  Side A   Side B
1
what are the portions of the electromagnetic spectrum?
 
x-rays, ultraviolet, and infrared.
2
what process are they used for?
 
they are used in photosynthesis.
3
what molecules are stored in the cell?
 
(carbohydrates-made of c, h, and o) starches, glycogen, glucose-short term
(lipids-c,...
4
where in the cell are these molecules found?
 
they are stored in the bonds of atoms.
5
how does photosynthises work?
 
proscess by wich all plants, some bacteria, and some protists use light energy to power chemical...
6
photosynthises formula?
 
6co2 + 6h2o --> c6h12o6 +6o2
6carbon dioxide molecules+6water molecules=glucose molecule+6oxygen...
7
what is energy?
 
the ability to do work.
8
examples of cellular energy?
 
nucleoli constructing-ribosomes
ribosomes building-proteins
spindle fibers...
9
what is atp?
 
(3 phosphates) a molecule made in the mitochondria, bonds between phosphate groups can be broken...
10
adp and amp?
 
they are atp but with less energy. adp is like a half way charged battery, and amp is a battery...
11
van helmont's discovery?
 
soil does not make a plant grow, the water does.
12
priestley's discovery
 
plants give off gas called oxygen.
13
ingenhousz discovery
 
plants need sunlight
14
what is a pigment?
 
a compound that absorbs some wavelengths and reflects others, causing some cells to have color.
15
what is chlorophyll?
 
it is located in the chloroplasts of plant cells.
16
which parts of the visible light spectrum does chlorophyll absorb the most energy?
 
red and blue waves
17
from which parts of the visisble light spectrum does chlorophyll absorbe the least energy?
 
green
18
what is the primary color for most plants?
 
green, because leaves absorb their chlorophyll t save it until spring.
19
what factors affect the photosynthesis?
 
sunlight (light intensity)
temperature
water
20
cellular resperation?
 
process that releases energy by breaking down food molecules in the presence of o2; made up...
21
anaerobic respiration/ fermentation
 
this presses releases very little energy and it exstracts energy without using oxygen. ther...
22
step 2 alcoholic fermentation
 
occuring in the cytoplasm of yeast (a fungus) and many bacteria. this process produces carbon...
23
step 2 lactic acid fermentation
 
occurs in the cytoplasm of all other organisms. when some fungi and bacteria perform lactic...
24
aerobic respiration (with oxygen)
 
ALOT OF ENERGY RELEASED
25
step 2: krebs/ citric cycle
 
occurs in the mitochondria after the glycolysis (cytoplasm) uses o2 to extract more energy...
26
step 3 electron transport chain
 
occurs in the mitochondria after krebs cycle. it is the aerobic cellular respiration process...
27
nutrients
 
substances in food that supply the energy and raw materials an organism needs to grow, repair...
28
for animals and humans, what is the most important nutrient?
 
water, carbohydrates, lipids(fats), proteins, vitamins and minerals.
29
water
 
the most imprtant nutrient, comprising 65- 70% of most animals.
30
what does water do?
 
maintains homeostasis (heats and cools slowly), water also enebals blood flow through vessles...
31
matabolism?
 
the sum of all chemical reactions in an organism.
32
carbohydrates
 
serves as short term energy (fruits,honey, and table sugar) and complex sugars/starches (potatoes,...
33
lipids
 
fats-protect organisms-provide padding. insulate-keep body heat in. stor long-term energy....
34
proteins
 
large polymers-large molecules-made up of amino acids-small molecules. the body can only...
35
vitamins
 
vitamins- organic molecules (a,b,c,d,e ect.) that help regulate body processes, often in...
36
minerals
 
inorganic molecules (iron, zinc, mg, ect.) that help regulate body processes and fulfill structural...
37
excersize
 
adults should be active for at least 30 min. a day and childeren should be active for 60...
38
magnification
 
an increase in size of an image
39
re3solving/resolution power
 
how clear the magnified specimen appears
40
feild of veiw
 
how much the image is seen through ocular
41
depth of veiw
 
how resolute/clear images appear at different distances from the ocular/eyepeice
42
how and when is energy released during cellular resperation?
 
it is released by breaking down food molecules.
43
factors that effect the reate of photosynthises
 
the amount of light(sunlight)
water 
and carbon dioxide
44
location of photosynthisis and cellular resp.
 
photosynthesis-cloroplasts
cellular resp.-mitochondria
45
what processes are necessary for atp?
 
breaking down of glucose in the cellular prosses
46
how do atp, adp and amp store energy?
 
they store the energy in the phosphates
47
how do atp, adp, and amp release energy?
 
when they need to release energy they break off the bond of a phosphate, releasing energy to...
