1

plants have helped the atmosphere develop to contain --% oxygen, which is vital to aerobic organisms

21

2

plants also make use of the -- that is produced by other living organisms

CO2

3

chlorophyll, which is responsible for reflecting green light and absorbing wavelengths of red and blue light which is around

660 and 430 nm

4

roots anchor plants and --

absorb water and nutrients

5

-- dramatically increase the absorption surface area of plant's roots

root hairs

6

carries water and minerals from the roots to the leaves

xylem

7

-- carries glucose from the leaves where it is synthesized

phloem

8

leaves large -- allows for more direct contact with sunlight and for absorption of CO2

surface area

9

gas exchange of CO2 input and O2 output as well as transpiration occurs through the --

stomata

10

stomatal opening is regulated by --

guard cells

11

stomata will open when the guard cells that flank it become -- through the osmosis of water into the cells

turgid

12

guard cells become turgid when there's a build up of -- in the interior of the guard cells

K+

13

K+ moves into guard cells through specific membrane channels when -- are pumped out of the cell, thereby making the exterior of the cell more positive

H+

14

with the increase of K+ inside the cell, water will enter by osmosis, causing guard cells to become --

turgid

15

stomata will close when the K+ is moved out of the cell, which will cause water to leave as well as make the guard cells --

flaccid

16

flowering plant's male reproductive organs

stamen

17

flowering plant's female reproductive organs

carpel

18

stamen is made up of the -- and --

anther and filament

19

carpel is made up of the --, --, and --

stigma, style, and ovary

20

pollen can be carried from the -- to the stigma

stamen

21

after fertilization, the -- will develop into the fruit

ovary

22

seeds develop from the --

ovule
