Answer 4

organisms that make their own food, example is plants

Question 5

heterotrophs and example of it

Answer 5

organisms that get energy from the food they eat and fungi and animals

Question 6

ultimate source of energy for all living things

Answer 6

the sun

Question 7

how many phosphates are stored in ATP

Answer 7

3 phosphates

Question 8

how many phosphates do ADP have

Answer 8

2 phosphates

Question 9

is photosynthesis exothermic or endothermic and why

Answer 9

endothermic because it’s taking energy IN to build the glucose

Question 10

what material coast epidermal cells to prevent excessive water loss

Answer 10

wax

Question 11

where is ground tissue located in plants

Answer 11

between dermal and vascular tissue

Question 12

where does most of photosynthesis take place in a plant

Answer 12

in the leaves

Question 13

3 FACTORS THAT AFFECT THE RATE OF PHOTOSYNTHESIS

Answer 13

WATER LIGHT, AND TEMPERATURE

Question 14

where do light dependent reactions take place

Answer 14

in the thylakoids

Question 15

what is ATP synthase

Answer 15

enzyme that makes ATP

Question 16

where do light independent reactions take place

Answer 16

in the stroma–empty space

Question 17

what are light independent reactions called

Answer 17

the Calvin cycle

Question 18

ultimate outcome of the calvin cycle

Answer 18

oxygen and glucose

Question 19

why do plant leaves appear green

Answer 19

pigment chlorophyll which reflects green light

Question 20

how do guard cells regulate the rate of transpiration based on temperature/environmental conditions

Answer 20

they stay closed during the hottest parts of the day to prevent water loss

Question 21

what is transpiration

Answer 21

the loss of water through plant leaves

Question 22

how does capillary action work with transpiration to keep water moving through the plant

Answer 22

plants use capillary action to move water through leaves

Question 23

Carrier molecule

Answer 23

Molecule that can bind to high energy electrons and transport that energy to other locations

Question 24

Equation for Photosynthesis

Answer 24

6C02+6H20 ====> C6H1206+602
Light
Carbon +water===> glucose to oxygen
dioxide

Question 25

Dermal Tissue

Answer 25

Has wax that prevents water loss

Question 26

Vascular tissue

Answer 26

Plant’s circulatory system

Question 27

Ground tissue

Answer 27

Has chloroplast for Photosynthesis

Question 28

Role of nadp and adp

Answer 28

The sun charges electrons and the NADP and ADP move them and convert them from electromagnetic energy to chemical energy
