Flashcards in biology ch 8 study guide Deck (28):
1

pigment

molecule that selectively absorbs light

2

main pigment of plants

chlorophyll

3

ATP

chemical energy for a cell

4

autotrophs and example of it

organisms that make their own food, example is plants

5

heterotrophs and example of it

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

6

ultimate source of energy for all living things

the sun

7

how many phosphates are stored in ATP

3 phosphates

8

how many phosphates do ADP have

2 phosphates

9

is photosynthesis exothermic or endothermic and why

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

10

what material coast epidermal cells to prevent excessive water loss

wax

11

where is ground tissue located in plants

between dermal and vascular tissue

12

where does most of photosynthesis take place in a plant

in the leaves

13

3 FACTORS THAT AFFECT THE RATE OF PHOTOSYNTHESIS

WATER LIGHT, AND TEMPERATURE

14

where do light dependent reactions take place

in the thylakoids

15

what is ATP synthase

enzyme that makes ATP

16

where do light independent reactions take place

in the stroma--empty space

17

what are light independent reactions called

the Calvin cycle

18

ultimate outcome of the calvin cycle

oxygen and glucose

19

why do plant leaves appear green

pigment chlorophyll which reflects green light

20

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

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

21

what is transpiration

the loss of water through plant leaves

22

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

plants use capillary action to move water through leaves

23

Carrier molecule

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

24

Equation for Photosynthesis

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

25

Dermal Tissue

Has wax that prevents water loss

26

Vascular tissue

Plant’s circulatory system

27

Ground tissue

Has chloroplast for Photosynthesis

28

Role of nadp and adp

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