Define Diffusion
the movement of particles from high to low concentration
the movement of particles from low to high concentration

Which gas leaves the stoma?
oxygen
carbon dioxide
Select with organelles are found in stoma
Nucleus
Vacuole
Chromosomal DNA
Cell Wall
What happens to the stoma when there isn't much water?
they open
they close
What is the name of the green pigment found in plant cells?
chloroplasts
chlorophyll
vacuole
cell wall
What is the function of chlorophyll?
to absorb light
to absorb carbon dioxide
to absorb glucose
to store glucose
Select all that are raw materials for Photosynthesis.
Water
Carbon Dioxide
Oxygen
Sunlight (Light Energy)
Glucose (Sugar/food)
Which organelle stores water for use in photosynthesis?
Chloroplast
Cell Membrane
Vacuole
Nucleus
Is Glucose (C6H12O6) a Raw Material (Ingredient) or Product of Photosynthesis?
Product
Raw Material
Neither
How does most of the water needed by the plant get into its leaves?
It enters through the stomata
The roots absorb it and then it travels up the stem
It's made during a chemical reaction in the leaf
The flowers capture water and deliver it to the leaves
Which of the following is the correct equation for PHOTOSYNTHESIS?
light + carbon dioxide + water --> glucose + oxygen
carbon dioxide + sugar + water --> oxygen + light
oxygen + light + water --> carbon dioxide + sugar
carbon dioxide + oxygen + water --> Light+ Sugar
Which of the factors directly affect the rate of photosynthesis?
Light intensity
Carbon dioxide levels
Water levels
Temperature
What are the limiting factors for the rate of photosynthesis?
Light intensity
Carbon dioxide levels
Water levels
Temperature
The leaf is green because
It has lots of vacuoles that contain chlorophyll
It has lots of chloroplasts that contain chlorophyll
It has lots of chloroplasts that contain oxygen
It has lots of chloroplasts that contain glucose
A root hair cell is adapted by:
Being stronger than a normal root cell
Having a large nucleus
Having lots of chloroplasts
Having a larger surface area
