photo synthesis

Question 1

photosynthesis is making things using ….

Answer 1

• light energy

Question 2

what do plants make , and what exactly is it ?

Answer 2

food > carbohydrate sugars > from this they can make anything

Question 3

what is the equation for glucose ?

Answer 3

C6 H12 O 6

Question 4

how is CH O2 made ?

Answer 4

the equation of glucose is broken down to make a new bond

Question 5

how do plants make water ?

Answer 5

they take carbon dioxide , mix it all around = water

Question 6

what is the waste gas produced through photosynthesis ?

Answer 6

oxygen

Question 7

what is the equation for photosynthesis ?

Answer 7

respiration photosynthesis

CO2 +H20 > C6 H12 O6 +O2

Question 8

when does photosynthesis take place ?

Answer 8

daytime

Question 9

when does respiration take place ?

Answer 9

night time

Question 10

what is the waste gas produced through respiration?

Answer 10

carbon dioxide

Question 11

equation for photosynthesis ?

Answer 11

carbon dioxide + water > glucose and oxygen

Question 12

what does rate mean ?

Answer 12

speed > high or low

Question 13

what effects the rate plants making food ?

Answer 13

• temperature
• light intensity
• water
• co2 levels

Question 14

why does temperature effects the rate that plants make food?

Answer 14

T

- more colisions with particles once temp is increased

Question 15

why does carbon dioxide levels effects the rate that plants make food?

Answer 15

CD L

- more co2 - more sugar is made

Question 16

why does light intensity effects the rate that plants make food?

Answer 16

L

- more sun = more energy more recations

Question 17

what 4 points of the process that plants make glucose ?

Answer 17

1- make other sugars e.g maltose , lactose
2-startch polymer of glucose , storage
3-makes molecules of lipid > fat, solid, animals have fat, plants have oil
4-make amino acid, plants make them all into -A-A-A-A- proteins

Question 18

how do you make oil and fat from glucose ?

Answer 18

-glucose > smash it up > oil > make oil into fat solid

Question 19

name some ways that gardeners control CO2 in green house ?

Answer 19

• use artificial light - photosynthesis carrie on at night

- use artificial carbon dioxide - photosyntheis carries on
