B. Keywords
2. Define: binary fission, callus, fertilization, grafting, pollination and reproduction.
Show answer
Answer: Binary fission: division of the parent body into two equal daughter cells. Callus: a mass of undifferentiated cells formed at a cut or wounded part. Fertilization: fusion of the male and female gametes (nuclei) to form a zygote. Grafting: joining a cut part (scion) of one plant to the rooted stem (stock) of another so that they grow as one. Pollination: transfer of pollen from an anther to a stigma. Reproduction: the process by which living organisms produce new individuals of their own kind.
Teacher's Note: Learn these as one-line definitions.
C. Multiple Choice Questions
(i) Asexual reproduction is seen in (a) Paramoecium (b) Amoeba (c) Spirogyra (d) All

Show answer
Answer: 1. False (it reproduces by cutting); 2. False (spores are formed inside the sporangium); 3. False (garlic reproduces by bulbs); 4. True; 5. False (it is fertilization); 6. False (fungi reproduce by spores).
Teacher's Note: Correct the false statements when you write the answer.
F. Very Short Answer Questions
1. Name a method of artificial vegetative propagation.
Show answer
Answer: Cutting, layering or grafting.
Teacher's Note:
2. Identify the type of reproduction in yeast.
Show answer
Answer: Budding, a type of asexual reproduction.
Teacher's Note:
3. Name the different parts of a flower.
Show answer
Answer: Sepals (calyx), petals (corolla), stamens (male part: anther and filament) and carpel or pistil (female part: stigma, style and ovary).
Teacher's Note: See the diagram below.
4. What type of asexual reproduction takes place in Chlamydomonas?
Show answer
Answer: Zoospore formation.
Teacher's Note: Zoospores are motile spores.
5. What do we call a flower having both sexual parts?
Show answer
Answer: A bisexual (hermaphrodite) flower.
Teacher's Note: Example: hibiscus and mustard.
G. Short Answer Questions
1. Differentiate between: (a) sexual and asexual reproduction (b) binary and multiple fission (c) self- and cross-pollination (d) cutting and grafting.
Show answer
Answer:
| Pair | Difference |
|---|---|
| Sexual and asexual | Sexual reproduction needs two parents and gametes and gives variation; asexual needs one parent, no gametes, and the offspring are identical. |
| Binary and multiple fission | In binary fission the parent splits into two cells (Amoeba); in multiple fission it splits into many daughter cells (Plasmodium). |
| Self and cross-pollination | In self-pollination pollen goes to the stigma of the same flower or plant; in cross-pollination it goes to a flower of another plant of the same kind. |
| Cutting and grafting | In cutting, a piece of a plant is planted in soil to grow roots; in grafting, a cut part of one plant is joined to another rooted plant. |
Teacher's Note: Use a table in the exam.
2. What is reproduction?
Show answer
Answer: Reproduction is the biological process by which living organisms produce new individuals of their own kind. It keeps the species from dying out.
Teacher's Note: Without it, a species would disappear.
3. Explain vegetative propagation and artificial vegetative propagation.
Show answer
Answer: Vegetative propagation is the formation of a new plant from a vegetative part (root, stem or leaf) of the parent, without seeds, as in potato (eyes), ginger (rhizome) and Bryophyllum (leaves). Artificial vegetative propagation is done by humans using methods such as cutting, layering and grafting to get plants with the desired qualities.
Teacher's Note: Vegetative means 'of the body of the plant'.
4. Define pollination. What is artificial pollination?
Show answer
Answer: Pollination is the transfer of pollen grains from the anther to the stigma. Artificial pollination is done by people, who place pollen of a chosen plant on the stigma of another with a brush, to get a hybrid of improved quality.
Teacher's Note: Pollination comes before fertilization.
5. Write short notes on: (a) spore formation (b) artificial pollination (c) seed and fruit formation.
Show answer
Answer: (a) Spore formation: tiny, light, spore cases (sporangia) burst and release spores, each of which grows into a new plant in damp, warm places; seen in fungi (bread mould), ferns and mosses. (b) Artificial pollination: pollen is moved by hand to a chosen stigma to produce hybrids. (c) After fertilization, the ovule becomes the seed and the ovary becomes the fruit; the other flower parts wither and fall off.
Teacher's Note: Mention an example for each.
H. Long Answer Questions
1. What is reproduction? Explain its types with examples.
Show answer
Answer: Reproduction is the production of new individuals of the same kind. Asexual: one parent, no gametes; offspring are identical. Examples: binary fission in Amoeba, budding in yeast, spore formation in fungi, and vegetative propagation in potato. Sexual: two sexes or gametes fuse to form a zygote, giving variation; examples are flowering plants (by pollination and fertilization) and most animals.
Teacher's Note: Two types: asexual and sexual.
2. What are the advantages and disadvantages of vegetative propagation?
Show answer
Answer: Advantages: plants grow faster; the new plants are exactly like the parent; plants that make no seeds (such as banana) can be grown; flowers and fruit appear earlier. Disadvantages: there is no variation, so a disease can spread to all plants; the plants may crowd the parent; and they do not spread to distant places.
Teacher's Note: Always give both sides.
3. Explain the structure and parts of a flower with an example.
Show answer
Answer: A flower is the reproductive part of a plant. Taking the hibiscus: the calyx (green sepals) protects the bud; the corolla (coloured petals) attracts insects; the androecium (male part) has stamens, each with an anther that holds pollen and a filament; the gynoecium (female part) is the pistil with stigma, style and ovary that holds ovules.
Teacher's Note: Use the diagram given above.
4. Explain the various agents of pollination.
Show answer
Answer: Pollen is carried by: wind (light, dry pollen, as in maize and grasses); insects (bright, scented flowers with nectar, as in sunflower and rose); water (aquatic plants such as Vallisneria); birds and animals (for example, sunbirds on some flowers); and humans, in artificial pollination.
Teacher's Note: Match each agent with a flower feature.
5. Write a short note on seed and fruit formation.
Show answer
Answer: After pollination, the pollen grain grows a tube down the style to the ovule, where a male gamete fuses with the egg cell (fertilization) to form a zygote. The zygote grows into the embryo inside the ovule, so the ovule becomes the seed. The ovary wall grows into the fruit, which protects the seed. Petals, stamens and the style dry up and fall off.
Teacher's Note: Ovule becomes seed; ovary becomes fruit.
