Class 6 Science - ODISHA

Living Creatures: Exploring their Characteristics

In this chapter, Class 6 students under the Odisha BSE board will explore the fascinating world of living things. You will learn to distinguish between biotic (living) and abiotic (non-living) components by studying their fundamental characteristics such as growth, respiration, nutrition, excretion, reproduction, response to stimuli, and movement. Understanding these traits helps us appreciate the diversity of life on Earth and forms the foundation for higher-level biological concepts tested frequently in board assessments.

Key Concepts

Cellular Organization

All living things are made up of tiny structural and functional units called cells, which can be single-celled or multi-celled.

Respiration

Living organisms take in oxygen and release energy from food to carry out their daily life activities.

Response to Stimuli

Living creatures react to changes in their environment, such as plants turning towards sunlight or animals running from danger.

Excretion

The biological process by which living organisms remove harmful waste products generated by their body's metabolic activities.

Reproduction

The process by which living organisms produce young ones of their own kind to ensure the survival of their species.

Important Formulas

Respiration: Glucose + Oxygen -> Carbon Dioxide + Water + Energy
Photosynthesis (in plants): Carbon Dioxide + Water + Sunlight -> Glucose + Oxygen

Board Exam Info

Under the Odisha BSE Class 6 Science curriculum, this chapter typically carries around 5 to 8 marks. Questions usually include objective multiple-choice questions, short answer questions defining key life processes, and differentiating between living and non-living things.

Frequently Asked Questions

Are viruses considered living or non-living?

Viruses are considered a bridge between living and non-living; they do not show characteristics of life until they enter a host body.

Do plants also respire like animals?

Yes, plants respire day and night by taking in oxygen and giving out carbon dioxide, alongside the process of photosynthesis during the day.

Why is movement not a universal feature to define living things?

Because plants are living things, but they do not move from place to place like animals, though their body parts show movement towards stimuli.
