Term
Autotrophs
Definition
Organisms such as plants, which make their own food.
Term
Heterotrophs
Definition
Organisms that obtain energy from the foods they consume.
Term
ATP (adenosine triphosphate)
Definition
One of the principal chemical compounds that living things us to store energy.
Term
ADP (adenosine diphosphate)
Definition
Has a structure similar to ATP but ADP has two phosphate groups instead of three.
Term
RELEASING ENERGY FROM ATP
Definition
The energy stored in ATP is released when ATP is converted into ADP and a phosphate group. Because a cell can add and subtract a third phosphate group, it has a way of storing and releasing energy as needed. ATP carries just enough energy to power a variety of cellular activities.
Term
Photosynthesis Equation
Definition
6CO2 + 6H2O Light C6 H12 O6 + 6O2
--------->
Chlorphyll
Term
Photosynthesis
Definition
Uses the energy of sunlight to convert water and carbon dioxide into oxygen and high-energy sugars.
Term
Pigments
Definition
the "THINGS" inside a chloroplast that absorbs sunlight, the plants principal pigment is chlorophyll.
Term
Thylakoids
Definition
Saclike membranes that are arranged in stacks known as grana. The thylakoids contain clusters of chlorophyll and other pigments and protein known as photosystems that are able to capture the energy of sunlight
Term
Stroma
Definition
Region outside the grana where the light INdependent reactions take place.
Term
Passive transport
Definition
uses no energy, substances move along a concentration gradient.
Term
Active transport
Definition
when a material moves from a high concentration to a low concentration.
4 types of active transport:
Endocytosis
phagocytosis
exocytosis
contracile vacoule
Term
Endocytosis
Definition
The process of taking a material into the cell by means of infoldings or pockets of the cell membrane(proteins).
Term
Phagocytosis
Definition
extensions of the cytoplasm that surround and engulf large particles
Term
Exocytosis
Definition
The membrane of the cell vacoule surrounding the material fuses with the cell membrane forcing contents out of the cell.
Term
Contractile Vacoule
Definition
used to remove excess water from a cell
Term
Hypertonic
Definition
Solution that has higher concentration of solute then surrounding solution
Term
Hypotonic
Definition
Solution that has a lower concentration of solute then surrounding solution.
Term
Isotonic
Definition
two solution have same solute concentrations.


( )
Term
Cytolysis
Definition
When red blood cell is exposed to water it will burst.
Term
Turgid
Definition
When plant cell exposed to water it will not explode because the cell wall prohibits it.
Term
Crenate
Definition
Animal cell will loose water and shrink when it has to give off water.
Term
Plasmolysis
Definition
when plant cell has to give water and the cell membrane will seperate from the cell wall.
Term
How is co2 obtained during photosythesis
Definition
it is obtained through leaf openings called stomata
Term
What are the pigments and what color do they suck in
Definition
Chloraphyll-Absorbs red and blue
Carotene-orange
xanthophyls- yellow
Term
Explain what happens in light dependent reaction
Definition
light is absorbed by pigments and H20 is needed and this yeilds 4 hydrogen ions an atp an nadph and a waste O2
Term
Cellular resperation equation
Definition
O2 + C6 H12 O6 -----> Co2 H20 36Atp(including atp's from glycolysis)
Term
Anaerobic(Fermentation)
Definition
Partially breaks down glucose with using no oxygen. Occurs in cytoplasm
Term
Aerobic Fermentation
Definition
Partially breaks down glucose first then uses oxygen to fully break down glucose to realease all its energy.
Term
Lactic Acid fermentation
Definition
-occurs in mammal muscle cells
-Turns pyrivic acid into lactic acid waste.
Term
How to get some sed 36ATP
Definition
1. glycolysis occurs and produces net 2 atp
2. O2 is used to completly break down pyruvic acid.
Term
What are the 3 things that the cell theory states?
Definition
-All living things are composed of cells.

-Cells are the basic units of structure and function in living things

-New cells are produced from existing cells.
Term
Difference between prokaryotes and euaryotes
Definition
Prokaryotic are small and all bacteria are prokayotic cells

Eukaryotic cells are larger can be plant or animal, eukaryotic cells have organelles that perform cellular functions.
Term
The nucleus
Definition
Contains genitic information
nucleolus is where ribosomes are produced
cromotin is in nucleus this is genitic information in the from of chromosomes.
Term
Golgi apparatus
Definition
Enzymes in the golgi apparatus attach carbohydrates and lipids to proteins.
Term
Level of organization
Definition
Cells----->Tissues------->Organs------>Organ systems
Term
Centrioles
Definition
cucumber things that play a role in cell division
Term
lysosome
Definition
break down some sed waste in cell that have enzymes in them.
Term
Endoplasmic Reticulam (rough and smooth)
Definition
smooth make lipids
rough makes proteins and has ribosomes on it.
