Plant Structure: Roots, Stems, and Leaves Worksheet

Question 1

What is one main job of roots in a plant?

Accepted Answer

One main job of roots is to absorb water and minerals from the soil for the plant.

Question 2

How do stems help a plant?

Accepted Answer

Stems help a plant by holding it upright and carrying water and food between the roots and leaves.

Question 3

What is one important job of leaves?

Accepted Answer

One important job of leaves is to make food for the plant using sunlight, air, and water.

Roots absorb water and minerals from the soil, and stems carry those materials to the rest of the plant.

Question 7

A leaf is called a food-making part because it uses sunlight, water, and carbon dioxide from the air to make food for the plant.

Question 8

Which plant part usually anchors the plant in the soil, and why is that important?

Accepted Answer

Its leaves will have trouble making food because they need sunlight to do their job well.

Question 10

Water is absorbed from the soil by the roots, moves up through the stem, and then reaches the leaves.

Question 11

A student says, "Leaves only make a plant look green." Explain why this statement is incorrect.
