facilitated diffusion
diffusion of materials across a cell membrane assisted by carrier molecules or protiens.
extensions of the cytoplasm surround and engulf large particles
Active Transport
an energy-requiring process that enables material to move across a cell membrane again a concentration difference.
Passive Transport
process in which particles move from an area of high concentration to an area of low concentration on their own using no energy
the process of taking material into the cell by means on infoldings, or pockets, ove the cell membrane.
The membrane surrounding the material fuses with the cell membrane, forcing the contents out of the cell.
group of tissues that work together to perform a specific function
Organ system
group of organs that work together to perform a specific function
the process of ting pockets froming along the cell membrane, filling with liquid, and piching off to form vacuoles within the cell.
a group of similiar cells that perform a particular function.
adenosine triosphate ATP
a compound that stores energy in three phosphate bonds
The process by which plants use the energy of sunlight to produce carbohydrates
Formula for Photosynthesis
carbon dioxide + water--light--> carbohydrate/glucose + Oxygen
green plants that use the sun to directly obtain energy
Organisms that cannot use the sun's energy directly
colored substances that absorb or reflect light.
the green pigment the enables plants to carry on photosynthesis. Red and blue are the colors of the visible spectrum that are absorbed by It
the first step in cellular respiration
Aerobic process
a process that requires oxygen
lactic acid
fermentation produces ATP in your muscle cells during rapid exercise when they cannot get enough oxygen
process that enables cells to carry out energy production in the absence of oxygen; breakdown of glucose and release of energy in which organic substances are the final electron acceptors
alcoholic fermenation
carried out by yeast cells and is of particuluar importance to brewers and bakers
the diffusion of water molecules through a selectively permeable membrane
the process by which molecules of a substance move from areas of high concentration of that substance to areas of lower concentration.
Van Leeunwenhoek
1600's developed microscope... looked at organisms in pond water
Robert Hook
1600's saw cell walls of dead cork cells and called them cells
Schlieden and Schwann
1800's proposed the cell theory
Cell theory
1.All living things are composed of cells
2.cells are the basic units of structure and function in living things.
3.All cells come from pre-existing cells
