UNIT 2 CHAPTER 11-PHOTOSYNTHESIS

Question 0

what are autotrophs ????

Answer 0

they’re organisms that can make their own food

Question 1

what is the ultimate source of energy for the planet ????

Answer 1

the sun motherfucker

Question 2

what is the process of photosynthesis ???

Answer 2

it is the process by which glucose & oxygen are made from carbon dioxide and water, light is needed and chlorophyll is used as a catalyst, takes place is plants mainly green plants.

Question 3

what is the formula of photosynthesis ????

Answer 3

6CO2 + 6H2O + LIGHT ————-> C6H12O6 + 6O2

chlorophyll

Question 4

WHAT IS ATP ?????

Answer 4

Adenosine TriPhosphate

Question 5

what does ATP do ????

Answer 5

made by light energy, supplies energy to make glucose, glucose is used later to make ATP,

Question 6

what are the roles of photosynthesis ?

Answer 6

plants use it to make their own food,

animals get food from these plants.

Question 7

what are the main events of photosynthesis ?

Answer 7

1-light is absorbed,
2-water is split,
3-the products of the splitting of water,
4-light energises electrons,
5-glucose is formed.

Question 8

describe the first event of photosynthesis (light is absorbed) ?

Answer 8

• chlorophyll traps sunlight,
• photosynthesis takes place in choroplasts,
• trapped sunlight provides energy to make glucose.

Question 9

describe the second event of photosynthesis ?

Answer 9

-some of the trapped sunlight energy is used to split water molecules,

Question 10

describe the third event of photosynthesis (the products of the splitting of water) ?

Answer 10

• electrons are passed to chlorophyll,
• protons are released into a storage pool for later use,
• oxygen is passed through the plant until to the leaf where it is disposed of.

Question 11

explain the 4th vent of photosynthesis ?

Answer 11

-sunlight energy is passed onto electrons to form high-energy electrons,

Question 12

explain the 5th event of photosynthesis ?

Answer 12

-high-energy electrons along with protons combine with carbon dioxide to form glucose.

Question 13

what are some resources of light for photosynthesis ?

Answer 13

• sunlight,

- artificial like (lamp).

Question 14

what are some resources of carbon dioxide for photosynthesis ?

Answer 14

• atmosphere,

- leaf cells.

Question 15

what are some resources of water for photosynthesis ?

Answer 15

-soil

Question 16

what experiment is there for photosynthesis ?

Answer 16

to investigate the influence of light intensity or carbon dioxide on the rate of photosynthesis ?

Question 17

what are the stages of photosynthesis ?

Answer 17

• light stage (no enzymes required),

- dark stage (enzymes required).
