Some topics covered in Biology Class 10 for CBSE syllabus are as follows:
1) Life Processes

2) How Do Organisms Reproduce

3) Heredity and Evolution

4) Control and Coordination

5) Our Environment

6) Management of Natural Resources

1) Life Processes
In previous years, questions of 1, 2, 3 as well as 5 marks have been asked from this chapter. We can also conclude that mostly 2 questions will be asked from this chapter. Thus, to score full marks in this chapter, we suggest that you read this chapter from NCERT thoroughly, as it has some small details which can be asked, like names and functions of enzymes, products formed during a particular reaction, etc.

Also do remember to practice drawing every diagram atleast once, as they have been asked in previous exams.

The concepts to be revised for life processes are:
Nutrition
In autotrophs
In amoeba
In humans
Respiration
Aerobic and anaerobic
In humans
Transportation
In humans
In plants
Excretion
In Humans
In plants

2) How Do Organisms Reproduce
In previous years, questions of 1, 2, 3 as well as 5 marks have been asked from this chapter.

Make sure that you read this from NCERT to score well in 1 nd 2 mark questions and practice drawing diagrams once before the exam.

The concepts to be revised for How do organisms reproduce are:

Role of DNA in reproduction
Sexual and asexual reproduction
Modes of asexual reproduction
Fission
Fragmentation
Regeneration
Budding
Vegetative propagation
Spore formation
Sexual reproduction in flowering plants
Sexual reproduction in Human Beings
Male reproductive system
Female reproductive system
Reproductive health

3) Heredity and Evolution
In previous years, questions of 2, 3 and 5 marks have been asked from this chapter. One important concept that is asked repeatedly is Mendel’s pea experiment, so make sure you study this thoroughly.

The concepts to be revised for Heredity and Evolution are:

Mendel’s pea experiment
Sex determination
Acquired and Inherited traits
Speciation
Homologous and Analogous organs
Fossils
Human evolution
4) Control and Coordination
In previous years, questions of 1, 2, 3 as well as 5 marks have been asked from this chapter. Thus, to score full marks in this chapter, we suggest that you read this chapter from NCERT thoroughly, as it has some small details which can be asked, like names and functions of hormones, etc.

Also do remember to practice drawing every diagram atleast once, as they have been asked in previous exams.

The concepts to be revised for Control and Coordination are:

Structure and functioning of a neuron
Reflex arc
Human brain
Chemical coordination in plants
Chemical coordination in humans
5) Our Environment
Mostly, questions of 1 or 3 marks are asked from this chapter.

The concepts to be revised for Our Environment are:

Ecosystem
Producers, consumers and decomposers
Food chain
Food web
Biological magnification
Ozone layer and its depletion
6) Management of Natural Resources
Questions of 2 and 3 marks have a higher probability of being asked from this chapter.

The concepts to be revised for Our Environment are:

Why we need to save resources
The three R’s to save our environment
Stakeholders
Chipko movement and restoration of Arabari forest
Sustainable management
Dams – advantages and disadvantages
Water harvesting
Coal and Petroleum
