Chapter 2 Flashcards
The movement of particles from regions of higher density to regions of lower density
Diffusion
The diffusion of water through semipermeable membrane
Osmosis
The movement of substances across a cell membrane without the use of energy by the cell.
Passive Transport
The movement of substances across the cell membrane that requires the cell to use energy.
Active Transport
The process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell.
Endocytosis
The process by which plants, algae and some bacteria use sunlight, carbon dioxide and water to make food.
Photosynthesis
The process by which cells use oxygen to produce energy from food
Cellular resporation
The breakdown of food without the use of oxygen
Fermentation
The life cycle of a cell
Cell Cycle
Ina eularyotic cell, one of the structures in the nucleus that are made up of DNA and protein; in a prokaryotic cell, the main ring of DNA
Chromosome
Chromosome that have the same sequence of genes and the same structure
Homologous Chromosomes
In eukaryotic cells, a process of cell division that forms two new nuclei, each of which had the same number of chromosomes
Mitosis
The cell division of the cytoplasm of a cell
Cytokinesis
The process in which a cell release a particle bu enclosing the particles in a vesicle that then moves to the cell surface and fuses with the cell membrane
Exocytosis
