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