Chapter 2 Flashcards
Diffusion
The movement of particals from regions of higher density to regions of lower density
Osmosis
The diffusion of water through a semipremeable membrane
Passive Transport
The movement of substances across a cell membrane without the use of energy by the cell
Active Transport
The movement of substances across a cell membrane with the use of energy by the cell
Endocytosis
The process by which a cell membrane surrounds a partical and encloses the partical in a vesicle to bring the partical into the cell.
Exocytosis
The process which a cell release a partical by enclosing the partical in a vesical that then moves to the cell surface and fuses with the cell membrane
Photosynthesis
The process by which plants, algae, carbon dioxide, and water to mkae food.
Cellular resperation
The process by which cells use oxygen to produce energy from food.
Fermentation
The breakdown of food without the use of oxygen
Cell cycle
The life cycle of a cell
Chromosone
In eukaryokic cell, one of the structures in the nucles
homologus chromosones
Chromosones that have the same sequence of genes and the same structure
Mitosis
A process of cell division that forms two new nucli , each which has the same number of chromosones
Cytokinesis
The division of cytoplasm of a cell
