Name the two parts of a tapioca plant where you would expect to find chlorophyll
guard cells & spongy mesophyll
palisade mesophyll cells & guard cells.
root cell & stem cells
chloroplast & chlorophyll
Where does the hydrogen needed for reduction of carbon dioxide during photosynthesis comes from?
mineral salt
soil
roots
water
Name the structure in a Palisade mesophyll cell which absorbs light energy during photosynthesis
chloroplast
Clorophyll
Water
chlorophyll
What is the role played by light energy
split up water molecules to produce nitrogen and hydrogen
split up water molecules to produce hydrogen and water
split up water molecules to produce hydrogen and oxygen
split up water molecules to produce carbon dioxide and oxygen
Name the by-product of photosynthesis
oxygen/ water
Carbon dioxide/hydrogen
Hydrogen/water
Water/carbon dioxide
What role does the stomata play in determining the rate of photosynthesis?
The stomata suddenly gets pregnant then gives birth to water 9 months later resulting in low glucose concentration
They occur in large numbers to ensure a high intake of carbon dioxide
hydrogen gas leaves and re-enter through the guard cell
carbon dioxide and oxygen enter and leave the leave through the stomata
What is the role of chlorophyll in photosynthesis
To capture the sun
to provide food for the plant
to capture light energy
to transport minerals throughout the plant
Name two factors affecting the rate of photosynthesis
Light intensity
Amount of oxygen
sodium levels
temperature
Name one important reason of photosynthesis
To ensure survival
Provide food for animals
maintains balance of oxygen and carbon dioxide in the atmosphere
provides humans with food
spongy mesophyll cell has fewer chloroplasts compared to palisade cell
True
False
In phototsynthesis, glucose fromed from oxygen and water
True
False
what is the function of the xylem in the leaves
transport water to the rest of the plant
transport oxygen to the rest of the plant and leaves
transport water and mineral salts to mesophyll cells
stores starch to transport to the res to the plant to the mesophyll cells
what is the function of the cuticle on the upper epidermis of the leaves?
prevents evaporation of water from the leaves
prevents water from entering
traps sunlight for photosynthesis
to perform photosynthesis
How long does it take for the leaf to destarch?
7 days
3 days
1 week
2 days
what are the 3 important factors that determine the limit of photosynthesis.
carbon dioxide concentration,nitrogen,oxygen
water,light intensity,temperature
light intentsity,carbon dioxide concentration,temperature
temperature,oxygen,light intentsity
