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, eventually developing roots, stems, and leaves.
Correct 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.
Correct 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.
Correct 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 that increase the surface area for water absorption. This water is then transported throughout the plant via the xylem.
Correct 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 formation of seeds and fruits. While an apple is a fruit (which develops from a flower), and leaves are part of the plant's structure, the correct answer directly relates to the definition of a flower.
Correct Answer: C) seed
