Cell vocab

TermDefinition
Cell Wall A rigid structure that surrounds the cell membrane and provides support to the plant cell
Cell Membrane A lipid layer that surrounds the cells surface
Cytoplasm The material or protoplasm within living cell excluding the nucleus
nuclear membrane A membrane that surrounds the nucleus in eukaryotic cells
nucleas The brain of the cell-controls all the cells activities
chromosomes thread like structures that carry genetic information in the form of genes
nucleolus Makes Ribosomes-found in nucleus (small and circular)
Mitochondria It has a double membrane-The site of cellular respiration (creates the cells energy)
Chloroplasts The organelle that uses the energy of sunlight to make food-only in plant cells
Golgi Bodies Helps make and package materials to be transported out of the cell
vacuole A membrane bound organelle that stores food and water
Endoplasmic Reticulum Helps in the production, procesing, and transport of proteins and in the prodution of lipids
Ribosomes Composed of RNA and protein; site of protein synthesis (makes protein)
Vesicle A small cavity or sac that contains materials in a eukaryotic cell
Lysosome Contains digestive enzymes-breaks down waste (garbage man of the cell)
Prokaryote cell DNA is circular in cell, single celled, no nucleus, no membrane-bound organelles, is bacteria and anchaea
Eukaryote cell Multicellular, has nucleus, found in animals and plants, DNA found in nucleus
Diffusion The movement of particles from regions of higher density to regions of lower density.
osmosis The diffusion of water through a semipermeable membreane
passive transport The movement of substances across a cell embrane without the use of energy by the cell
active transport the movement of substances across the cel membrane that requires the cell to use energy
endocytosis the process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
exocytosis 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
semipermeable only certain substances can pass through
