Science Review Questions – Unit on Plants
1.
How are plants and animals similar?
Plants and animals are similar because they both need food, air, water, and space
to live and grow.
2.
What can plants do that animals cannot?
Plants can make their own food.
3.

carbon dioxide to enter the leaf.
6.
How do roots help a plant?
Roots help hold up the plant. They take in water and minerals. Roots also help
store food made in plant leaves.
7.
What is a taproot?

Stems support leaves, flowers, and fruits. Stems carry food from the leaves to
the roots. Some stems help protect the plants from enemies.
10.
How are roots and stems alike and different?
Alike: Help support plant and transport materials.
Different: Roots are below ground, while stems are usually above ground; some
stems help make food or store water, some roots store food.
11.
What materials do the stem tubes move?
The stem tubes move water, minerals, and food.
12.
Describe how a flower makes a seed.
Pollen is placed on the tip of a certain part of the flower, then seeds form at the
bottom of that part.
13.
How do some insects help seeds form? Insects move pollen from one part of a
flower to the flower part that makes seeds.
14.
What do flowers do? Flowers make pollen, seeds, and fruit that will surround and
protect the seeds.
15.
How are deciduous trees and grasses alike and different?
A tree has stiff, woody stems, while most grasses do not. A deciduous tree loses
only its leaves in the fall, while grasses die back to the roots. Both make seeds.
16.
What are two ways to group plants?
By the kinds of roots, stems, and leaves they have, and by the kinds of flowers, or
cones they have.
17.
Describe two kinds of plant parts that can make seeds.
The flowers in flowering plants have special parts that make either seeds or
pollen. One kind of cone in a coniferous plant is larger and has stiff, scaly parts
that make seeds.
18.
What is a cone? A cone is a part of a coniferous tree that makes seeds.
