Class 10 Science 2 Life Processes Part 2 Worksheet
This Class 10 Science 2 Chapter 3 Life Processes in Living Organisms Part 2 Worksheet is prepared according to the Maharashtra State Board Science and Technology Part 2 syllabus. It supports preparation for unit tests, school examinations, preliminary examinations and the Maharashtra SSC Board examination.
The worksheet contains Maharashtra State Board exam important questions, MCQs, one-word answers, matching pairs, diagram-based activities, scientific reasons, comparisons, short-answer questions and detailed explanatory questions. Selected previous board exam questions are included with their examination-year labels, making it useful as an SSC question bank.
Students revise asexual reproduction, sexual reproduction, binary fission, multiple fission, budding, fragmentation, regeneration, vegetative propagation, flower structure, pollination, fertilisation, seed formation and human reproductive processes. Questions also encourage age-appropriate understanding of reproductive health and responsible behaviour.

Asexual Reproduction
Asexual reproduction involves a single parent and does not include the fusion of male and female gametes. Offspring are generally genetically similar to the parent, although small differences may arise due to mutation.
| Method | Process | Example |
|---|---|---|
| Binary fission | One parent cell divides into two daughter cells | Amoeba and Paramecium |
| Multiple fission | One parent cell produces many daughter cells | Plasmodium |
| Budding | A small outgrowth develops into a new organism | Yeast and Hydra |
| Fragmentation | The body breaks into fragments that grow independently | Spirogyra |
| Regeneration | A body part develops into a complete organism | Planaria |
| Spore formation | Spores germinate under suitable conditions | Rhizopus |
Vegetative Propagation
Vegetative propagation is a form of asexual reproduction in plants in which roots, stems or leaves develop into new plants. It may occur naturally or through artificial methods used in agriculture and horticulture.
| Plant Part or Method | Example |
|---|---|
| Stem tuber | Potato |
| Rhizome | Ginger |
| Leaf buds | Bryophyllum |
| Cutting | Rose or sugarcane |
| Grafting | Mango and citrus plants |
| Tissue culture | Rapid production of selected plants |
Sexual Reproduction
Sexual reproduction generally involves the formation and fusion of male and female gametes. The fusion of gametes is called fertilisation, and the resulting cell is called a zygote. Sexual reproduction produces variation because hereditary material from two parents is combined.
| Point | Asexual Reproduction | Sexual Reproduction |
|---|---|---|
| Number of parents | Usually one | Usually two |
| Gamete fusion | Absent | Present |
| Variation | Usually limited | Comparatively greater |
| Speed | Often faster | Usually slower and more complex |
Sexual Reproduction in Flowering Plants
Structure of a Flower
The stamen is the male reproductive part of a flower and consists of the anther and filament. The pistil or carpel is the female reproductive part and consists of the stigma, style and ovary. Ovules are present inside the ovary.
Pollination
Pollination is the transfer of pollen grains from the anther to the stigma. In self-pollination, pollen reaches the stigma of the same flower or another flower on the same plant. In cross-pollination, pollen is transferred to a flower on another plant of the same species.
Fertilisation and Seed Formation
After pollination, a pollen tube grows through the style towards the ovule. The male gamete travels through the pollen tube and fuses with the female gamete. After fertilisation, the zygote develops into an embryo, the ovule develops into a seed and the ovary commonly develops into a fruit.
Human Reproduction and Reproductive Health
In humans, reproductive organs become functionally mature during puberty. The male reproductive system produces and transports sperm, while the female reproductive system produces ova and supports fertilisation and development of the embryo.
Reproductive health includes correct scientific knowledge, personal hygiene, balanced nutrition, respectful behaviour, responsible decision-making and medical guidance when required. Students should use accurate biological terms and avoid social myths or misleading information.
Common Mistakes Students Should Avoid
- Writing that asexual reproduction always requires two parents
- Confusing binary fission with multiple fission
- Writing regeneration and fragmentation as identical processes
- Confusing pollination with fertilisation
- Writing that pollen grains are produced by the stigma
- Writing that the ovary develops directly into the embryo
- Forgetting that the ovule generally develops into the seed
- Drawing reproductive diagrams without correct labels

What is the main difference between asexual and sexual reproduction?
Asexual reproduction usually involves one parent and no fusion of gametes. Sexual reproduction involves the formation and fusion of male and female gametes and generally produces greater variation.
What is binary fission?
Binary fission is an asexual reproduction method in which one parent cell divides into two daughter cells. Amoeba is a commonly studied example.
How does budding occur in yeast?
A small bud develops on the parent yeast cell. The nucleus divides, one daughter nucleus enters the bud and the bud grows before separating as a new cell.
What is vegetative propagation?
Vegetative propagation is asexual reproduction in plants through roots, stems or leaves. For example, potato grows from stem tubers, while Bryophyllum develops plantlets from leaf margins.
What is the difference between pollination and fertilisation?
Pollination is the transfer of pollen grains from anther to stigma. Fertilisation is the fusion of the male and female gametes to form a zygote.
What happens after fertilisation in a flower?
The zygote develops into an embryo, the ovule generally develops into a seed and the ovary commonly develops into a fruit.
Why does sexual reproduction produce variation?
Sexual reproduction combines hereditary information from two parents. Meiosis and fertilisation produce new combinations of genes, so offspring are not genetically identical to either parent.
