Class 6 Science - ICSE-BIOLOGY
Living Things
The chapter 'Living Things' for Class 6 ICSE Biology introduces students to the fundamental characteristics that distinguish living organisms from non-living things. Students will explore essential biological processes such as growth, respiration, nutrition, excretion, reproduction, and response to stimuli. Understanding these core life processes is crucial for students as it builds the foundational knowledge required for higher-level biology in ICSE board exams. Questions from this chapter frequently test observational skills and the ability to differentiate between living and non-living entities using specific scientific criteria.

Cellular Organization
All living things are made up of tiny basic units of life called cells, which can be single-celled or multi-celled.
Nutrition
Living organisms require food and nutrients to obtain energy for survival, growth, and repair of body parts.
Respiration
It is the process by which living things release energy from food by taking in oxygen and giving out carbon dioxide.
Excretion
The biological process of removing metabolic waste products and harmful substances produced within the body of a living organism.
Response to Stimuli
Living things have the ability to perceive changes in their environment, known as stimuli, and react to them.
Reproduction
The process by which living organisms produce young ones of their own kind to ensure the survival of their species.

Frequently Asked Questions
Are viruses considered living or non-living?
Viruses are considered a borderline case because they do not show characteristics of life when they are outside a host cell, but they multiply and show life processes inside a living host.
Do plants show movement like animals do?
Plants do not move from place to place, but they show movement in parts, such as roots growing towards water or leaves closing when touched.
Why is excretion important for living things?
Excretion is important because waste products can become toxic and poisonous to the body if allowed to accumulate.
