Chap 2 New Book Flashcards
The diffusion of water through a semipermeable membrane
Osmosis
The movement of particles from regions of higher densities to regions of lower density
Diffusion
In the middle of substances across the 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 in which a cell releases a particle by enclosing the particle in a vesicle that then moves to the cell surface and fuses with the cell membrane
Exocytosis
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 respiration
The breakdown of food without the use of oxygen
Fermination
The life cycle of a cell
Soul cycle
It eukaryotic cell one of the structures in the nucleus that are made up of DNA and protein and a prokaryotic cell main ring of DNA
Chromosome
Chromosomes that had the same sequence of genes and the same structure
Homologous chromosomes
In eukaryotic cells a process of cell division that forms to nuclei in each of which has the same number of chromosomes
Mitosis
The division of the cytoplasm of the cell
Cytokinesis
