Tags and Description

45 Terms

1

guard cells

changes its shape to open & close the stomata

New cards
2

xylem

brings water from roots up to where photosynthesis takes place

New cards
3

phloem

takes extra, unneeded glucose & moves it to the sink

New cards
4

pore

CO2 enters & oxygen and water come out through here

New cards
5

vain

made up of phloem & xylem (vascular bundle)

New cards
6

cuticle

waxy, NON-LIVING layer that waterproofs the leaf & protects plant from drying out

New cards
7

lower epidermis

layer of cells produces cuticle on bottom of leaf

New cards
8

spongy layer of mesophyll

has big open air spaces, does some photosynthesis

New cards
9

palisades layer of mesophyll

tightly packed layer of cells where most of photosynthesis takes place

New cards
10

upper epidermis

layer of cells that produces cuticle on top of leaf

New cards
11

air spaces

allows the movement of CO2 up from palisades & allows oxygen to leave the leaf

New cards
12

what does cycling maintain in the enviornment?

homeostasis

New cards
13

4 processes the water cycle involves

evaporation, transpiration, condensation, precipitation

New cards
14

evaporation

happens when heat changes water from a liquid to a gas

New cards
15

transpiration

happens when water evaporates from the leaves of plants - depends on the properties of water

New cards
16

what happens as moist air rises?

it cools

New cards
17

condensation

the process by which water vapor turns into a liquid forming clouds

New cards
18

precipitation

comes in the form of rain, snow, sleet, hail, or fog & it falls when the water drops become heavy

New cards
19

runoff

when water runs down hills & mountains into bodies of water

New cards
20

Infiltration

when water soaks into the soil & collects as groundwater. Helps to build the water table

New cards
21

what determines the amt of water the atmosphere can hold?

temp & air pressure

New cards
22

how does the water cycle help the earth

it prevents large changes in global temperatures

New cards
23

what do the carbon & oxygen cycles use?

they’re interdependent on each other and use respiration to produce oxygen & photosynthesis to produce CO2

New cards
24

what is the oxygen produced in photosynthesis?

a waste product & made from water, not CO2

New cards
25

what are DNA & RNA?

nucleic acids

New cards
26

lipids

fats/oils/steroids

New cards
27

what are carbon & hydrogen?

organic compounds

New cards
28

photoautotrophs

release O2 into the atmosphere by photosynthesis

New cards
29

who needs oxygen?

all life with a mitochondria absorbs it to use during cellular respiration EXCEPT some prokaryotes

New cards
30

why do living organisms need Carbon?

to create organic molecules / macromolecules

New cards
31

producers

absorb CO2 from the atmosphere during photosynthesis & release CO2 during cellular respiration

New cards
32

consumers

intake oxygen when they feed & move it up the food chain

output CO2 during cellular respiration

New cards
33

decomposers

intake CO2 when they feed on organic matter

return organic molecules to the soil during decomposition

New cards
34

humans

release CO2 into the atmosphere when fossil fuels are burned for energy

New cards
35

4 main carbon reservoirs in BIOSPHERE

Atmosphere - as CO2 gas

Ocean - as dissolved CO2 gas

Land - in organisms, rocks, soil

Underground - as coal & fossil fuels & calcium carbonate in rocks

New cards
36

Where does CO2 in atmosphere come from?

-volcanic activity

-human activity (burning fossil fuels)

-cellular respiration

-decomposition

New cards
37

how do plants absorb water

through their roots, using cohesion & adhesion to move water to the leaves

New cards
38

what is transpiration aka?

evaporation

New cards
39

what does high humidity do to transpiration & why?

slows down transpiration because it slows the movement of water to roots

New cards
40

what does increased light do?

increases photosynthesis, increasing transpiration

New cards
41

what happens during droughts?

the stoma close so transpiration stops, making photosynthesis stop or slow

New cards
42

absorption occurs at the…

roots

New cards
43

cohesion & adhesion happens in the…

xylem

New cards
44

transpiration takes place in the…

stoma of the leaves

New cards
45

explain process of water movement in plants

water is absorbed through the roots and brought up to the leaves through cohesion & adhesion

exits through transpiration in the stoma of the leaves
