Plants Growth and Needs Worksheet

Question 1

Name three things most plants need to grow.

Accepted Answer

Most plants need water, sunlight, and air to grow. Many plants also need space and nutrients from soil.

Question 2

A plant is kept in a dark closet for many days. What will likely happen to the plant?

Accepted Answer

The plant will likely become weak and may stop growing because it is not getting sunlight. Without light, plants cannot make the food they need.

Question 3

What job do roots do for a plant?

Accepted Answer

Roots hold the plant in the ground and take in water and nutrients from the soil. They help the plant stay alive and steady.

Question 4

What job does the stem do for a plant?

Accepted Answer

The stem holds the plant up and helps move water and nutrients to other parts of the plant. It supports the leaves and flowers.

Question 5

Leaves are important to plants. Explain why.

Accepted Answer

Leaves help plants make food using sunlight, air, and water. They are important because they help the plant grow and stay healthy.

Question 6

A child waters one plant every day and never waters another plant. How will the two plants be different after a while?

Accepted Answer

The watered plant will likely grow better and look healthier. The plant without water will likely droop, dry out, or die.

Question 7

Circle the living thing: rock, plant, pencil. Explain your choice.

Accepted Answer

The plant is the living thing because it grows, needs water and air, and can make seeds. A rock and a pencil do not grow or need those things.

Question 8

Why do many plants need soil?

Accepted Answer

Many plants need soil because soil holds water and gives nutrients to the roots. Soil also helps anchor the plant in place.

Question 9

Put these plant life stages in order: seed, adult plant, seedling.

The correct order is seed, seedling, adult plant. A seed begins to grow into a seedling, and then it becomes an adult plant.

Question 10

What does a seed need before it can begin to grow?

Accepted Answer

A seed needs water and the right conditions, such as warmth, to begin to grow. After it starts growing, it will need light and air too.

Question 11

A plant near a sunny window grows taller than a plant in a shady corner. What is one reason why?

Accepted Answer

One reason is that the plant near the sunny window gets more sunlight. More sunlight helps the plant make food and grow.

Question 12

How are plants and animals alike in one way?

Accepted Answer

Plants and animals are alike because both are living things that need air and water to live. Both also grow and change over time.

Question 13

How are plants and animals different in one way?

Accepted Answer

Plants can make their own food using sunlight, but animals cannot. Animals must eat food from plants or other animals.

Question 14

Why is space important for a plant?

Accepted Answer

Space is important because a plant needs room for its roots, stem, and leaves to grow. If plants are too crowded, they may not get enough light, water, or nutrients.
