Thinking Like a Scientist
100

This part of the plant captures most of the sunlight used for photosynthesis.

Leaves

100

Photosynthesis converts this type of energy into chemical energy.

Light energy

100

This process pulls water upward from the roots as water evaporates from leaves.

Transpiration

100

Plants take in this gas during photosynthesis.

CO2 

Carbon Dioxide

100

A plant grown under this color of light will grow worst.

Green

200

This tissue carries sugar made in photosynthesis to the rest of the plant.

Phloem

200

This molecule stores chemical energy made during photosynthesis.

Glucose

200

This term means “water sticking to itself.”

Cohesion

200

This gas is released as a byproduct of photosynthesis.

O2

Oxygen

200

Covering stomata with wax would prevent this gas from entering the leaf.

Carbon dioxide

CO2

300

These tiny openings on leaves allow carbon dioxide and oxygen to move in and out.

Stomata

300

What are the "ingredients" for a chemical reaction?

Reactants

300

This term means “water sticking to other surfaces,” such as xylem walls.

Adhesion

300

Why do animals need photosynthesis?

All energy in the ecosystem originates in photosynthesis
300

Why do low temperatures slow photosynthesis?

Stomata close

Fluids move slowly

Chlorophyll goes dormant if winter

400

Xylem and phloem are both examples of this type of plant tissue.

Vascular Tissue

400

This equation represents photosynthesis.

CO₂ + H₂O + light → C₆H₁₂O₆ + O₂

400

Together, adhesion and cohesion help water move upward through this tissue.

Xylem

400

If stomata are blocked, this process would slow or stop.

Photosynthesis

400

Leaves appear green because chlorophyll reflects this color.

Green

500

This pigment gives leaves their green color and absorbs light energy.

Chlorophyll

500

Photosynthesis is responsible for providing this to nearly all food chains.

Calories

500

If adhesion and cohesion did not occur, this process would be disrupted.

Water transport to leaves from roots for photosynthesis.

500

This environmental factor directly affects the rate of gas exchange in leaves.

Temperature

Light

CO₂ availability

500

Leaves change color in fall because chlorophyll breaks down and this happens.

Other pigments become visible
