Let us see biology notes for class 10 chapter wise:

Chapter 6 – The Process of Life

NCERT Class 10 Science Chapter 6 describes the process of life. There are six life processes which all living organisms carry out. They are:

  • Movement
  • Respiration
  • Growth
  • Reproduction
  • Excretion
  • Nutrition

This chapter also teaches about nutrition, namely the process of eating and using it for growth, metabolism, and recovery. The stages of nutrition are consumption, digestion, absorption, transportation, assimilation and excretion. Nutrition is further divided into:

Autotrophic Nutrition

Autotrophic nutrition involves the consumption of simple inorganic materials from the environment and the use of an external energy source such as the sun to synthesize complex high-energy organic matter.

Heterotrophic Nutrition

Heterotrophic nutrition involves ingesting complex materials produced by other organisms. The different types of heterotrophic diets are the parasite diet, saprophytic diet, and the holozoic diet.

The next topic is human nutrition

The different nutritional measures are consumption, digestion, esophagus, stomach, small intestine, bile, absorption, assimilation and ingestion.

The next subtopic is Respiration

Which beautifully describes the human respiratory system. The various elements of the human respiratory system are the lungs, bronchi, larynx, throat and others. During the respiratory process, organic compounds such as glucose are broken down into energy in the form of ATP. ATP is used to provide energy for other reactions in cells. Respiration can be:

Aerobic

  • The respiration process takes place in the presence of oxygen.
  • CO2, water and energy are the products of aerobic respiration.
  • The first step glycolysis takes place in the cytoplasm, while the next in the mitochondria.
  • Occurs in all higher organisms.
  • In this process complete oxidation of glucose occur.

Anaerobic respiration

  • The respiration process takes place in the absence of oxygen.
  • Ethyl alcohol, CO2 and a little energy are the end products of anaerobic respiration.
  • The first step takes place in cytoplasm and next in mitochondria.
  • In this process the glucose molecule is incompletely broken down.
  • The process of anaerobic respiration takes place in lower organisms like yeast, some species of bacteria and parasites like tapeworm.

Aerobic breathing gives the body more energy. For plants, soil is the closest and richest source of raw materials such as nitrogen, phosphorus and other minerals. In humans, the transport of materials such as oxygen, carbon dioxide, food and waste products is a function of the circulatory system. The heart, blood and blood vessels altogether form circulatory.

In highly differentiated plants, the transport of water, minerals, food and other materials is a function of the vascular network, which consists of xylem and phloem. In humans, the waste product in the form of dissolved nitrogen compounds is removed from the nephrons in the kidneys. Plants use a variety of techniques to dispose of waste material.

Chapter 7 – Control and Coordination

Chapter 7 of Grade 10 control and coordination notes, which are the functions of the nervous and hormonal systems in our bodies. Nervous system responses can be classified as reflex actions, voluntary actions, or involuntary actions. The nervous system uses electrical impulses to carry messages. They receive body information from sensory organs and work through muscles.

Class 10 biology control and coordination notes pdf is available here. Chemical coordination is observed in plants and animals. The hormones produced in one part of the body are transferred to another part to achieve the desired effect. The feedback mechanism regulates the effects of hormones.

Notes to control and coordination

  • Organisms move in response to various types of stimuli such as light, heat, nutrients / food, etc.
  • All activities in animals are controlled and coordinated by the nervous and hormonal systems.
  • Hormones are chemical messengers that help the nervous system carry out various functions. They are secreted by endocrine glands.
  • Hormones in plants coordinate movement.

NCERT Class 10 Science Solutions Chapter 7 – Control and Coordination

For grade 10 science chapter 7 describes various nervous actions such as

  • Reflux effect
  • Voluntary Action
  • Accidental act
  • Describes the control and coordination of the nervous system.
  • Hormonal effects are regulated by a feedback mechanism.
  • Uses electric pulses to carry messages.

Chapter 8 – How Organisms Reproduce

Unlike other life processes, reproduction is not essential for sustaining the life of an organism. Additional DNA copies and cell tools are made from the cells involved in the process. Depending on their body structure, different organisms use different modes of reproduction. When dividing, many bacteria and protozoa divide into two or more daughter cells. Organisms such as Hydra can regenerate when broken down into pieces.

They can also shed off shoots that will mature into new individuals. The roots, stems and leaves of some plants develop into new plants through asexual reproduction. This is an example of asexual reproduction, where a person creates a new generation. Sexual reproduction involves two people to create a new human being. The DNA replication mechanism creates variations that are useful for ensuring the survival of species. The sexual reproductive system allows for greater variety.

Reproduction in flowering plants involves transferring pollen grains from the anthers to the stigma, which is known as pollination. Fertilization follows. Body changes at puberty, such as an increase in breast size in girls and new facial hair in boys, are signs of puberty.

The male reproductive system in humans consists of the testes that produce sperm, the vas deferens, seminal vesicles, prostate, urethra, and penis.

The female reproductive system in humans consists of the ovaries, fallopian tubes, uterus and vagina.

Sexual reproduction in humans involves the entry of sperm into a woman’s vagina. Fertilization takes place in the fallopian tube. Contraception to avoid pregnancy can be achieved through the use of condoms, oral pills, and other methods.

Chapter 8: How do organisms reproduce? NCERT’s Class 10 Science Solution

In NCERT’s Class 10 Science Solutions, Chapter 8, the different playback modes are described as follows:

  • Sexual reproduction
  • Sexual reproduction
  • Propagation in flowering plants
  • It has been suggested that reproduction involves the production of cells involved in the DNA copying process, as well as additional cellular devices.
  • Summarizes the mechanisms for copying DNA
  • Describe body design and how different organisms use different reproductive systems

Chapter 9 – Inheritance and Evolution

We have seen that the reproduction process produces new individuals who are similar but slightly different. We discuss how certain variations are also created during asexual reproduction. The rule for inheriting traits in humans has to do with the fact that fathers and mothers contribute practically the same amount of genetic material to their children.

This means that every trait can be influenced by the DNA of the father and mother. Gender can be determined by various factors in different species. Non-reproductive tissue changes are caused by environmental factors that are not hereditary. Specifications can occur when variations are combined with geographic isolation. Evolutionary relationships are followed in the classification of organisms. Tracing common ancestors back in time leads to the idea that inanimate objects must have produced life at some time.

Complex organs can also develop at an intermediate stage because of the survival advantage. Organs or properties can be adapted to new functions during evolution. It cannot be said that evolution moved from a lower form to a higher form. In contrast, evolution appears to have resulted in more complex body designs, although simpler body designs continue to evolve. The study of human evolution shows that we all belong to a species that evolved in Africa and gradually spread throughout the world.

Chapter 15 – Our Environment

This chapter describes how the various components in the environment interact and how we affect the environment. Various components of the ecosystem are interdependent. Producers provide solar energy to the entire ecosystem. When moving from one trophic level to another, energy is lost. This constricts the number of trophic levels in the food chain.

The food chain is described in detail using examples related to nature such as forests, grasslands and lakes. Human activities affect the environment. The use of chemicals such as CFCs has threatened the ozone layer. Because the ozone layer protects from ultraviolet solar radiation, it can damage the environment. The waste that we produce can be biodegradable or non-biodegradable. The disposal of the waste that we produce creates serious environmental problems.

Chapter 16 – Sustainable Natural Resource Management

In the previous class, we learned about some natural resources such as land, air and water and studied how the various components in nature repeatedly circulate. In this chapter we will look at some of our resources and how we can use them. Our resources such as forests, wildlife, water, coal and oil must be used sustainably.

We can reduce the pressure on the environment by sincerely applying the adage “reject, reduce, reuse, reuse and recycle” in our lives. Forest resource management must consider the interests of various interest groups. The use of water resources by constructing dams has social, economic and ecological consequences. There are alternatives to large dams. They are locally specific and can be designed so that local people have control over their local resources. Fossil fuels, coal and oil will eventually run out. Therefore, and because burning it is polluting our environment, we must use these resources wisely.

Working model of science for class 10 biology

The working model of science for class 10 biology are scientific activities that aim to make certain characteristics of the world more understandable from the point of view of visualization and determination by referring to existing knowledge, usually accompanied by known knowledge. This includes identifying and selecting relevant facts and aspects for better understanding, analysis, quantification, and targeting operations.

Some of the models used include conceptual models, graphic models, mathematical models and operational models. The science working model has a wide spectrum in areas such as systems theory, science teaching, and knowledge visualization.

There is some basis for the working model of science for class 10 biology, it can be said that it is not possible to establish experimental conditions under which scientists can obtain direct results. Next includes stimulation, structure, systems, and finally includes model creation and evaluation.

Where stimulation is nothing more than a technique for modeling. A system consists of interacting units. There is a growing possibility in different meta-theories, techniques used and separate collections of materials with all kinds and special scientific models.
