Cards

Term
Diffusion
Definition
particles moving from an area of high concentration to an area of low concentration
Term
Osmosis
Definition
the diffusion of water through a semi-permeable membrane
Term
channels
Definition
passageways in the cell membrane through which small particles travel
Term
Passive Transport
Definition
Moving small particles through channels without the use of energy from the cell (from high to low concentration)
Term
Active Transport
Definition
Using energy to move small particles through channels from an area of low concentration to an area of high concentration
Term
Endocytosis
Definition
the process of moving large particles into a cell
Term
Exocytosis
Definition
The process of moving large particles out of a cell
Term
vesicle
Definition
a pouch in a cell made of a section of the cell membrane
Term
Photosynthesis
Definition
the process of making food using energy from the sun
Term
Cellular Respiration
Definition
the process of using oxygen to break down food
Term
Fermentation
Definition
The process of breaking down food without the use of oxygen
Term
lactic acid
Definition
produced by the process of fermentation, it causes muscle to burn
Term
Cell Cycle
Definition
life cycle of a cell
Term
Interphase
Definition
The first stage of the cell cycle, when the cell grows and copies insides
Term
Mitosis
Definition
Stage 2 of the cell cycle, the process of chromatid separation
Term
Binary Fission
Definition
process that bacteria use to reproduce
Term
Chromosomes
Definition
the structure that DNA is organized into in a eukaryotic cell
Term
Homologous Chromosomes
Definition
pairs of chromosomes (one from each parent)
Term
Chromatids
Definition
Identical copies of chromosomes
Term
Centromere
Definition
Holds chromatids together during the first phases of mitosis
Term
Prophase
Definition
first phase of mitosis - chromosomes condense and nuclear membrane dissolves
Term
Metaphase
Definition
phase two of mitosis - chromosomes line up along equator of the cell
Term
Anaphase
Definition
Phase 3 of Mitosis - chromatids separate and move to opposite sides of the cell
Term
Telophase
Definition
Phase four of mitosis - nuclear membrane forms around each set of chromosomes
Term
daughter cells
Definition
the two identical cells that are a result of the parent cell during the cell cycle
Term
Cytokinesis
Definition
separation of two animal cells once mitosis is complete - the cell pinches in two
Term
Cell plate formation
Definition
the separation of plant cells once mitosis has been completed
