Parts And Functions Of The Plant Quiz

1.

This plant part takes in sunlight and produces food for the plant.

Explanation
The leaf is the plant part that takes in sunlight and uses it to produce food for the plant through a process called photosynthesis. The leaf contains chlorophyll, which is a pigment that captures sunlight and converts it into energy. The energy is then used to convert carbon dioxide and water into glucose, which is the plant's food source. Therefore, the leaf is responsible for the plant's ability to produce its own food and is essential for its growth and survival.

2.

This part of the plant makes the seeds.

Explanation
The flower is the part of the plant that produces seeds. It contains the reproductive organs, including the male stamens and the female pistil. The flowers are responsible for pollination, where the pollen from the stamens is transferred to the pistil, leading to fertilization and the development of seeds. Therefore, the flower is essential for the plant's reproduction and the production of seeds.

This plant part provides support.

Explanation
The stem of a plant provides support by holding up the leaves, flowers, and fruits. It also transports water, nutrients, and sugars between the roots and the rest of the plant. The stem is typically upright and rigid, allowing the plant to stand tall and reach towards the sunlight. Additionally, the stem contains vascular tissues that help in the distribution of resources throughout the plant.

4.

This part of the plant is usually below the ground.

Explanation
The correct answer is "root, roots" because the question states that this part of the plant is usually below the ground. The root is the part of the plant that anchors it in the soil and absorbs water and nutrients. It is typically found underground, providing stability and support to the plant. The plural form "roots" is also correct as it refers to multiple root structures of a plant.

5.

This plant part provides support, transportation between roots and leaves, location of food storage also holds leaves up towards sunlight.

Explanation
The stem is the plant part that provides support to the plant. It also serves as a transportation system, allowing water and nutrients to move between the roots and leaves. Additionally, the stem is responsible for storing food and holding the leaves up towards sunlight for photosynthesis.

6.

What part of the plant makes seeds, reproduces through pollination, which is carried by insects, animals or by wind?

A.

Root
B.

Flower
C.

Stem

Correct Answer
B. Flower

Explanation
Flowers are the reproductive structures of plants that produce seeds. They contain the reproductive organs, including the male stamen and the female pistil, where pollen is transferred for fertilization. Flowers are pollinated through various means, including by insects, animals, or wind, which carry the pollen from one flower to another. This process allows for the successful reproduction of plants, ensuring the continuation of their species.

What plant part holds the plant in place, draws water and nutrients from the soil?

A.

Root
B.

Stem
C.

Flower

Correct Answer
A. Root

Explanation
The root is the plant part that holds the plant in place, draws water and nutrients from the soil. Roots anchor the plant into the ground, providing stability and support. They also absorb water and minerals from the soil through tiny root hairs, which are extensions of the root. These absorbed nutrients are then transported to other parts of the plant, such as the stem and leaves, for growth and development. The flower, on the other hand, is the reproductive part of the plant and does not play a role in anchoring or nutrient absorption.

8.

What plant part takes in sunlight, carbon dioxide and water and releases oxygen and glucose (sugar)?

A.

Root
B.

Stem
C.

Leaf

Correct Answer
C. Leaf

Explanation
Leaves are the plant part that takes in sunlight, carbon dioxide, and water through tiny pores called stomata. They contain chlorophyll, which captures the energy from sunlight and converts it into chemical energy through the process of photosynthesis. During photosynthesis, oxygen is released as a byproduct, while glucose (sugar) is produced and stored in the leaves. This glucose serves as a source of energy for the plant and is transported to other parts of the plant through the stem. Therefore, the correct answer is leaf.
