Science Unit 1 Lesson 1

What is photosynthesis?

• A green substance found in leaves and some stems that captures the energy in sunlight.

• The process in which plants use energy from the sun to make food.

• A plant structure where food is usually made.

• A picture that is taken in sync.

Click all the things that plants need to survive.

• Sunlight

• Water

• Food

• Shelter

• Nutrients

What is the formula for photosynthesis?

• sunlight + sugar + oxygen = carbon dixoide + water

• oxygen + carbon dioxide = water

• sugar = food

• sunlight + water + carbon dioxide = sugar + oxygen

The vascular system is a system of tubes inside the plant that connects the leaves, stems, and roots. The tubes carry food, water, and nutrients to all parts of the plant.

• True

• False

Food is made in this plant structure:

• The stem

• The root

• The leaf

• The flower

What process does this diagram show?

A green substance found in leaves is __________________.

• chlorophyll

• photosynthesis

• slime

• sugar

What TWO things does the stem do for the plant?

• Make it pretty.

• Help hold it up.

• Make it green.

• Connect the roots with the leaves

Click the TWO things that the root plant structure does for the plant:

• Cheers for it to grow.

• Take in water from the soil.

• Anchors it in the soil so it doesn't get washed away or fall over.

• Digs a hole for it to stay in.

Click TWO types of roots:

• Fibrous

  roots

• Stray roots

• Gray

  roots

• Taproot
