SEED AND FRUIT FORMATION_UNSOLVED PAPER

Topic: Seed and Fruit Formation

Time: 90 mins | Marks: 45 | Difficulty: Medium
multiple choice question

Q1. After fertilisation, which structure generally develops into a seed?

  1. Ovule
  2. Stigma
  3. Petal
  4. Anther

Q2.After fertilisation, the ovary of a flower generally develops into the:

  1. Seed
  2. Root
  3. Pollen grain
  4. Fruit

Q3. Which structure of a flower contains the ovules before fertilisation?

  1. Anther
  2. Ovary
  3. Filament
  4. Stigma

Q4. The zygote formed after fertilisation eventually develops into the:

  1. Embryo
  2. Pollen grain
  3. Fruit wall
  4. Stigma

Q5. Which of the following is most directly associated with the formation of a new plant inside a seed?

  1. Embryo
  2. Petal
  3. Filament
  4. Stigma

Q6. Which sequence correctly represents the major changes after fertilisation?

  1. Ovule --> Seed and Ovary --> Fruit
  2. Ovary --> Seed and Ovule --> Fruit
  3. Seed --> Ovule and Fruit --> Ovary
  4. Pollen --> Ovary and Stigma --> Seed

Short questions

Q1. What happens to the ovule after successful fertilisation in a flowering plant?

Q2. What happens to the ovary after fertilisation? How is this change related to fruit formation?

Q3. What is an embryo? How is it related to the zygote formed after fertilisation?

Q4. Why is a seed important for the continuation of a flowering plant's life cycle?

Q5. 

When you eat a mango, you may notice a large seed inside the fruit.

Which structures of the flower are associated with the formation of the mango fruit and its seed?

Q6. 

Students observe a flowering plant in the school garden. After some time, the flowers disappear and small fruits begin to develop.

What reproductive event must have taken place before this change could occur?

long questions

Q1. Explain the changes that take place in a flower after fertilisation. Describe the fate of the zygote, ovule, and ovary during this process.

Q2. Describe the structure and importance of a seed. Explain the roles of the seed coat, embryo, and stored food in the development of a new plant.

Q3. Farmers grow crops such as wheat, pea, mustard, and mango using seeds produced by flowering plants. Explain how fertilisation leads to seed and fruit formation and why this process is important for the next generation of plants.

application-based questions

Q1. 

A student cuts open a tomato and notices many small structures inside it.

a) Which flower structure is associated with the formation of these seeds?
b) Which part of the flower develops into the fruit containing them?

Q2. 

A student records the following events:

  1. Fertilisation takes place.

  2. A zygote is formed.

  3. The zygote develops into an embryo.

  4. The ovule develops into a seed.

  5. The ovary develops into a fruit.

Arrange these events in their correct sequence.

Q3. 

Two flowering plants produce flowers, but only Plant A develops fruits containing mature seeds.

Plant A has undergone successful fertilisation, while Plant B has not.

Compare the likely reproductive outcome of the two plants and explain why successful fertilisation is important for seed formation.
