Class 10th CBSE Biology Classes By Arshi

Life Processes:

• Topics: Nutrition (autotrophic/heterotrophic), Respiration, Transport (blood, heart, lymph, transpiration), Excretion.

• Outcomes: Explain different modes of nutrition, describe human systems (respiratory, circulatory), understand photosynthesis, explain transpiration, differentiate aerobic/anaerobic respiration.

Control & Coordination:

• Topics: Plant (tropisms, hormones), Animal (nervous system, reflex action, hormones).

• Outcomes: Describe plant movements, identify plant hormones, explain the human nervous system, differentiate voluntary/involuntary/reflex actions.

Reproduction:

• Topics: Asexual & Sexual reproduction in plants/animals, Reproductive Health (family planning, STDs).

• Outcomes: Compare sexual/asexual reproduction, understand human reproductive health issues.

Heredity & Evolution:

• Topics: Mendelian laws, Sex determination, Basic concepts of Evolution.

• Outcomes: Apply Mendelian principles, understand sex determination, relate heredity to evolution. 

Our Environment:

Topics: Ecosystem and its Components:

• Definition of ecosystem: Biotic (living) and Abiotic (non-living) components.

• Types of Ecosystems: Natural (forests, ponds) vs. Artificial (gardens, crop-fields, aquariums).

Food Chains and Food Webs:

• Producers, Consumers (Primary, Secondary, Tertiary), and Decomposers.

• Trophic Levels and energy flow in an ecosystem.

• 10% Law of energy transfer.

Environmental Problems:

• Ozone layer depletion: Causes (CFCs) and effects.

• Biodegradable and Non-biodegradable substances.

Waste Management:

• Methods for reducing, reusing, and recycling garbage.

• Impact of waste on the environment (Land and Water pollution).

Biological Magnification:

• Accumulation of harmful chemicals at different trophic levels.
