Osmosis
The diffusion of water through a semipermeable membrane
Diffusion
The movement of particles from regions of higher density to lower density
Photosynthesis
The process by which plants algae and some bacteria use sunlight carbon dioxide and water to make foo
Cellular respiration
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 lifecycle of a cell
Chromosome
In a eukaryotic cell one of the structures in the nucleus that Are made up of DNA and protein and a prokaryotic cell the main ring of DNA
Homologous chromosomes
Chromosomes that have the same sequence of genes and the same structure
Mitosis
In eukaryotic cells a process of cell division that forms to nuclei each of which has two of the same number of chromosomes
Cytokinesis
The division of the cytoplasm
Molecules
Molecules are what water is made up of
Semipermeable
Semipermeable mean that only certain substances can pass through
Channels
The passageway that small particles take are called channels
Passive transport
The movement of substances across the cell membrane without the use of energy by the cell
Active Transport
The movement of substances across the cell membrane that requires the cell to use energy
