Plant

​Plant Structures

​Plants needs: water, air, sunlight, space, and nutrients.

Nutrients are substances that a living thing needs to stay healthy.

Plants need energy to meet these needs.

Energy is the ability to perform work or change something.

Plants use structures such as leaves, stems, and roots to obtain energy.

​ترجمة

Nutrients = مغذيات

stems = ساق النبات

roots = جذور النبات

Multiple Choice

Which of the following structures do plants use to obtain energy?

• Leaves

• Stems

• Roots

• All of the above

Multiple Choice

Which of the following is NOT a need of plants?

• Nutrients

• Space

• Sunlight

• darkness

• Air

Multiple Choice

Nutrients are substances that a living thing needs to stay healthy.

• True

• False

Multiple Choice

What is energy?

• The growth of plant cells.

• The ability to perform work or change something.

• The absorption of water by plant roots.

​Plant Structures

Plants need carbon dioxide from the air to make their food.

Tiny opening on the underside of most leaves allow air to enter.

These openings - called stomata- can close and prevent water from escaping.

Other plant structures obtain the other materials that the plant needs. water is absorbed by plants roots.

Water is absorbed by plants roots.

It travels up the center of the stem through specialized tissues called xylem.

Multiple Choice

Plants need carbon oxygen from the air to make their food.

• True

• False

Multiple Choice

From where do Plants need carbon dioxide to make their food?

• From the air

• From the water

• From the space

• From the sun

Multiple Choice

Tiny opening on the underside of most _____ allow air to enter.

• Roots

• Stems

• Leaves

Multiple Choice

Tiny opening on the underside of most leaves that allow air to enter is called:

• stomata

• xylem

• Nutrients

• Energy

Multiple Select

Benefits of the stomata:

• allow air to enter

• prevent water from escaping

• absorb water

• make food

Multiple Choice

Water is absorbed by ___

• roots

• stems

• leaves

Multiple Choice

The water travels up from the roots to ----

• the center of the stem

• the center of the leave

• the end of the stem

• the end of the leave

Multiple Choice

The water travels up the center of the stem through specialized tissues called ----

• stomata

• xylem

• Nutrients

• carbon dioxide

• Plant need enough space where they grow for their roots to spread out and absorb water and nutrients from the soil.

• Water and carbon dioxide combine in presence of light energy to produce sugar and oxygen.

• The sugars are what the plant uses for food.

• Phloem are tissues that transport sugars to all parts of the plant.

  It drives the movement of materials throughout a plant.

• Transpiration is the evaporation of water from a plant's leaves.

  As water evaporates from leaves, more water is carried from the bottom of the plant to the top.

  Water moves into the leaf, replacing the water that has evaporated.

​Plant Needs

Multiple Choice

Why does a plant need enough space where it grows?
