Question 1

What is photosynthesis?

Answer 1

Photosynthesis is the process when some autotrophs such as plants, algae, and some bacteria convert light energy glucose

Question 2

Reactants and products for photosynthesis (equation)

Answer 2

• 6Co2+6H2o+light energy->C6H12O6+6o2
• reactants: Co2 and water
• products: glucose and oxygen

Question 3

Where does photosynthesis occur?

Answer 3

chloroplast

Question 4

Parts of the chloroplast

Answer 4

outer and inner membrane, stroma, thylakoid, grana, ribosomes

Question 5

Where in the chloroplast do you find chlorophyll? what is chlorophyll?

Answer 5

• Chlorophyll is the pigment found in the thylakoid membranes.
• It absorbs light energy and plays a key role in photosynthesis, allowing plants to convert light into food.

Question 6

What affects the rate of photosynthesis? (be able to read graphs)

Answer 6

light intensity, temp, amount of water, Co2, chlorophyll levels

Question 7

Xylem and stomata

Answer 7

• The xylem carries water from the roots up to the stem and leaves.
• The stomata opens for gas exchange.

Question 8

photons

Answer 8

particles of light

Question 9

what does the phloem do

Answer 9

transports food in leaf

Question 10

what splits the water during photosynthesis?

Answer 10

The sunlight excites chlorophyll electrons, and this energy is used to power the enzymes that splits the water molecules and releases o2 into the air.

Question 11

what opens and closes the stomata?

Answer 11

guard cells

Question 12

explain what happens to the h+ions during phase one

remember the photosynthesis diagram

Answer 12

• h+ions are from the split water and will move from the thylakoids to the stroma.
• the h+ions now move over and are used in the light independent phase
