Name 4 structures that are needed for Photosynthesis.
|
Light, Chlorophyll, Water, and Carbon Dioxide
|
|
|
Describe 4 ways in which the structure of a leaf helps with photosynthesis.
|
1. Large SA to absorb sunlight
2. Leaves are thin so that water does not have to travel far to get to the plant cells 3. Leaves contain Chlorophyll to absorb sunlight to make glucose 4. Leaves have Stomata which takes in oxygen and lets out CO2 |
|
|
What is glucose converted to, to make cell walls?
|
Glucose=Cellulose
|
|
|
What do the Roots do?
|
Trap/absorb water for the plant
Hold the Plant in place=provide structure |
|
|
What does the Stem do?
|
Holds the Leaves and carries the flow of water upward
|
|
|
What do the Leaves do?
|
They are the Food Factory of the plant, they make glucose from the chlorophyll.
|
|
|
What do the Flowers do?
|
The flowers are the reproductive organs and spread seed
|
|
|
What does water also contain for the plant
|
Minerals from the soil that the roots absorb with the water
|
|
|
Explain the difference between Xylem and Phloem.
|
Xylem=carries water and mineral salts
Phloem=carries food/glucose |
|
|
What is the Stomata?
|
They are pores in the leaf that allow the exit of oxygen and entry of CO2.
|
|
|
What do the Guard Cells do for the Stomata?
|
They surround the stomata to control the size of the hole.
|
|
|
Why does the Stomata open?
|
To release water by evaporation, to exchange gases with air and because the pressure is high.
|
|
|
Why does the Stomata close?
|
To save water the internal pressure will be low.
|
|
|
What is Transpiration?
|
Process where plants loose water vapor by evaporation. The movement upward of water.
|
|
|
What does transpiration depend on?
|
Wind
Temperature Time of Day Humidity |
|
|
The blood cells that carry oxygen and CO2 are:
|
Red Blood Cells
|
|
|
What is the name of the blood vessel that transports blood from the left ventricle to the rest of the body?
|
Aorta
|
|
|
Clotting is the function of:
|
Platelets
|
|
|
White blood cells help fight:
|
Disease
|
|
|
Arteries carry blood:
|
away from the heart
|
|
|
What vessel carries blood from the heart to the lungs?
|
pulmonary artery
|
