Let's solve the comprehension questions step by step and explain each answer.
Question 1: How does a plant start?
-
Options:
- A) flower
- B) roots
- C) seed
Explanation:
A plant typically starts its life cycle from a
seed. The seed contains the embryo of the plant and the nutrients it needs to germinate. Once the seed absorbs water, it begins to grow into a seedling, which eventually develops into a mature plant.
Answer: C) seed

Question 2: The roots
-
Options:
- A) hold the plant
- B) hold the leaves
- C) hold the flowers
Explanation:
The primary function of roots is to anchor the plant in the soil, providing stability and preventing it from being uprooted by wind or other forces. Additionally, roots absorb water and nutrients from the soil. They do not directly hold the leaves or flowers.
Answer: A) hold the plant

Question 3: Where do you find seeds?
-
Options:
- A) Stem
- B) Flower
- C) leaves
Explanation:
Seeds are typically found in the
flower or in structures derived from the flower, such as fruits. After pollination, the ovary of the flower develops into a fruit, which contains seeds. Seeds are not found in the stem or leaves.
Answer: B) Flower

Question 4: How does a plant get water?
-
Options:
- A) From the Roots
- B) Seeds
- C) People
Explanation:
Plants absorb water primarily through their
roots from the soil. The roots have tiny hair-like structures called root hairs that increase the surface area for water absorption. While people can water plants, this is not the natural primary source of water for plants.
Answer: A) From the Roots

Question 5: What is a flower?
-
Options:
- A) apple
- B) leaves
- C) seed
Explanation:
A flower is the reproductive part of a plant. It is where pollination occurs, leading to the production of seeds and fruits. An
apple is actually a fruit, which develops from a flower after pollination. Leaves are part of the plant but are not flowers. Seeds are produced by flowers but are not the same as flowers.
Answer: None of the options are correct. However, if we must choose, the closest option is
C) seed, as seeds are produced by flowers, but this is not the best answer since a flower is not a seed.
