Q

Makes Oxygen

A

anything with chloroplast can make oxygen, but it is produced as a waste although most organisms on earth need it.

Q

Chloroplasts do what…

A

they are carbohydrate factories that use solar E to form glucose, unless it is stored then it is turned into starch, lactose, sucrose, or cellulose.

25
what's the petiole of leaf anatomy
the pipeline which products of photosynthesis are moved from leaves to all of plant
26
cuticle does what
prevents water from escaping and protects the plant from bacteria, fungi, and insects
27
what is the epidermis
typically only one cell thick and is underneath the cuticle, the outermost layer of cell
28
where does the most part of photosynthesis occur at
the leaf
29
why is the leafs structure associated with its function?
because CO2 must come in and O2 must go out, H2O cant diffuse out
30
what does the stomata do
channels what come in and out of the leafs, and allows natural gases to pass through
31
what colors are found in the chloroplast always
green mostly, but yellow, orange, red, and brown are always in the chloroplast just not always visible
32
what "chemicals" do chloroplast contain
chlorophyll, Carotene, and xanthophyll
33
energy carrier
ATP ---> ADP + P + Energy
34
Election carriers
NADPH ----> NADH + 3ATP FADH2 ----> FAD +2 ATP
35
what does photosynthesis mean
putting together with light
36
light reaction
its light dependent and takes place in the grana, requires chlorophyll
37
photo-phosphorylation
chlorophyll captures the light and produces energized electrons, and the water molecule splits
38
electron transport train
produces from photo-phosphorylation make ATP and NADPH
39
glucose in plants can come in many forms...
proteins, carbohydrates, and lipids
40
how many times does carbon go around the Calvin cycle
3 for C3 or 4 for C4
41
when does CO2 come in during photosynthesis
during the Calvin cycle
42
why can u keep producing photosynthesis
it reaches its max level in the chloroplast
43
light intensity
the stronger the light, the R.O.P. increases until max
44
CO2 concentration
the higher concentration, the R.O.P. goes up until max
45
Temperature level
as heat increases so does R.O.P. until it gets to hot then plants start to die.
46
adaptation def
special features that allow particular plant/animals to live in an environment
47
what happens to CO2 if stomata are closed
no glucose can be produced because no CO2 is getting in
48
how to plants in dry/hot environments get there CO2
at night they open there stomata and let in the CO2 and store it until the morning or until needed
49
CAM
Crassulacean Acid Metabolism
50
aerobic respiration
converting glucose into ATP with O2 in the mitochondria
51
anaerobic respiration
Converting glucose into ATP without oxygen, in the cytoplasm
52
Krebs cycle
in aerobic respiration and it takes pyruvate and makes CO2 and high energy elctrons with it. In the mitochondria
53
electron transport chain
Step of aerobic respiration that take the high energy electrons from the Krebs cycle to change ADP to ATP.
54
glycolysis
first step to cellular respiration.
55
Krebs Cycle and Electron Transport Chain
2nd and 3rd steps to cellular respiration, in the mitochondria
56
Definition of Cellular Respiration
breaking down glucose into Energy
57
photosynthesis pigment
Chemicals that absorb light energy and use it to carry out photosynthesis. Contained in thylakoid membranes in chloroplast. Ex. chlorophyll a, chlorophyll b, carotenoids, xanthophylls, and phycobilins.
58
heterotrophs
must consume all marco molecules from outside sources
58
which organelle loses water
the central vacuole
59
what happens as you digest food in you
the energy is used for works in the body or it escapes to produce body heat
60
fermentation (anaerobic cellular respiration)
partially degrades glucose without O2 EX. pickles, muscles, and yogurt
61
how much ATP does anaerobic organisms make,
1 glucose=2 ATP
62
how much ATP does aerobic organisms make
6C glucose= 38 ATP
