Life Processes Class 10 full Chapter (Animation) | Class 10 Science Chapter 6 | CBSE | NCERT

The chapter begins with an introduction to the concept of life processes, emphasizing their importance for maintaining bodily functions and survival. These processes include nutrition, respiration, transportation, and excretion.

Nutrition is defined as the process of obtaining and utilizing food for energy and tissue repair. It involves two primary types: autotrophic, where organisms like plants produce their own food through photosynthesis, and heterotrophic, where organisms depend on others for food.

The detailed explanation of autotrophic nutrition includes photosynthesis, where plants convert carbon dioxide and water into glucose using chlorophyll and sunlight. The importance of chloroplasts in this process is highlighted.

Heterotrophic nutrition is explained with examples, such as how organisms derive nutrients from consuming organic matter, with specific references to decomposers like fungi and bacteria.

The concept of human nutrition is introduced, discussing its complexity involving five processes: ingestion, digestion, absorption, assimilation, and excretion.

Respiration is defined, highlighting its role in energy release. It is divided into external respiration (breathing in oxygen, expelling carbon dioxide) and internal respiration (exchange of gases at the cellular level).

The two types of respiration, aerobic (with oxygen) and anaerobic (without oxygen), are explained, providing examples of each and their significance in energy metabolism, including fermentation processes.

Transportation in humans is covered, focusing on blood's role in circulating nutrients and waste removal, detailing the components of blood and the heart's structure in this vital function.
