QuestionAnswer
a branch of science studying living things biology
group of similar organisms that can interbreed species
cell maintaining constant conditions homeostases
as a group, change over time evolution
educated guess hypothesis
group used for comparison control
a set of steps to test a hypothesis experiment
another name for a living thing organism
protein catalyst that speeds up the rate of reactions enzyme
cells that don't have a nucleus or membrane bound organelles prokaryote
cells that do have a nucleus or membrane bound organelles eukaryote
cell structure with specialized function organelle
diffusion of water through a selectively permeable membrane osmosis
main energy molecule for cell work ATP
producers use the sun to make sugars photosynthesis
main pigment in photosynthesis chlorophyll
organism that can make own food autotroph
must consume other organisms for energy heterotroph
process that required oxygen aerobic
process that doesn't require oxygen anaerobic
unit for energy in food calorie
The 8 characteristics of all organisms made of cells, reproduce, have DNA, grow and develop, obtain and use materials, respond to environment, maintain a stable internal environment, change over time
4 element that make up 96% of our bodies carbon, hydrogen, oxygen, nitrogen
function of carbs quick energy
lipids energy storage, cushions organs
proteins multipurpose molecule
nucleic acid info molecule
contains DNA, directs cell function nucleus
site of protein production ribosomes
outer boundary of cells; selectively permeable cell membrane
processes and transports proteins and lipids ER
packaging center for lipids and proteins Golgi
outer boundary of plant cells cell wall
found in nucleus; where ribosomes are made nucleolus
site of photosynthesis chloroplast
site of aerobic respiration mitochondria
storage area for water, wastes, and enzymes vacuole
structures for movement cilia and flagella
attachment for spindle fibers in mitosis centriols
clear fluid inside cell cytoplasm
difference between active and passive transport active = energy needed passive = energy not needed
examples of active and passive energy active = exocytosis, endocytosis passive = osmosis, diffusion
types of processes carried out by cells cell division, transporting materials, obtaining nutrients
ATP is made by gaining/losing energy from exothermic/endothermic types of reactions. ATP releases/gains energy for use in exothermic/endothermic reactions gaining, exothermic, releases, endothermic
then a phosphate is remove from ATP, energy is ___________. When a phosphate is added to ATP energy is ___________. released, gained
equation for photosynthesis 6H20+6C02+sunlight= C6H12O6 + 6O2
in photosynthesis equation, where does water come from roots/soil
in photosynthesis equation, where does carbon dioxide come from air
in photosynthesis equation, where does oxygen go air
in photosynthesis equation, where does glucose go into plant for storage
2 stages of photosynthesis are light dependent or ________ _________ __________, and the light independent or __________ _________. energy building reactions, Calvin cycle
stages of photosynthesis occur in the chloroplast
energy building reactions happen in the thylakoid mem
Calvin cycle happens in the stroma
In first stage of photosynthesis ___ and _____ are made, with the waste product of _________ exiting the leaves. ATP, NADPH, Oxygen
In the second stage of photosynthesis ______ coming from the air is used to make ________ CO2, sugar
equation for cell respiration C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP
what happens in glycolysis and where C6H12O6 breaks down into pyruvate, 2 ATP, 2 NADH, happens in cytoplasm
what happens in Krebs cycle and where makes electron carriers for ETC, NADH, FADH2, CO2, 2 ATP, happens in matrix of mitochondria
what happens in ETC and where Make ATP, O2, picks up electrons into H2O, happens in inner membrane/cristae
what is oxygens job in aerobic respiration end electron accepter in electron transport chain
compare and contrast photosynthesis and cellular respiration P: Both: CR: -happens in chloroplast - use elements - happens in mitochondria -only autotrophs can do. - necessary for life -all cells do this
how much ATP would a bacteria get from a molecule of glucose 2
how much ATP would our cells get from a molecule of glucose 36
which foods give us the most ATP lipids
function of fermentation free up NAD+ to go to glycolysis
what does life need water, reproduction, flow of energy from sun

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
