photosynthesis

photosynthesis

The process in which plants make their own food

Three things needed for photosynthesis

light, c02, water

photosynthesis happens in the chloroplasts

cloroplasts are structures found in plant cells

Multiple Select

click on all the elements needed for photosynthesis

• dirt

• co2

• water

• light

Multiple Choice

What is the name of the structure in a plant cell that has the function of photosynthesis?

• cytoplasm

• nucleus

• chloroplasts

• mitochondria

Water is absorbed through the roots of the plant

tiny tube like structures called Xylem carry the water to the leaves so photosynthesis can occur

Xylem

tube like structures that carry water up from the roots to the leaves

Multiple Choice

What "organ" of the plant absorbs the water for the process of photosynthesis to begin?

• leaves

• roots

• stem

• flowers

Multiple Choice

What is the job of the xylem?

• to take waste products to the leaves

• to transfer water to glucose

• to transport water up from the roots to the leaves

Co2

carbon dioxide is in the air. Humans and animals exhale CO2 during respiration (when they breath)

CO2

Co2 enters the plant through the leaves. Leaves have microscopic holes in them called Stoma (stomata)

Stoma- Stomata

The tiny holes open and allow CO2 to enter the plant.

Multiple Choice

How does CO2 enter a plant?

• roots

• stomata

• stem

• water

Light

Plant cells have chloroplasts. These structures have other structures inside of them called chlorophyll. When the light hits the plant it is absorbed in the chlorophyll

Multiple Choice

What are chlorophyll?

• tiny structures inside of chloroplasts where light is absorbed during photosynthesis

• tiny tubes that transport water to the leaves

water+Co2+light

these elements combine and a chemical reaction occurrs....creating glucose (sugar)

Multiple Choice

water +Co2+light =

• salt

• glucose

• spices

• candy

Glucose=sugar

This is the food the plant needs to survive

Co2

is a gas that is a mixture of the elements Carbon and Oxygen- plants do not use the oxygen part of Co2...so they release it during photosynthesis

oxygen

this waste product is then released through the stomata

Multiple Choice

What is the waste product of photosynthesis

• water

• glucose (sugar)

• Carbon

• oxygen
