Term
cytoplasm
Definition
Cytoplasm is the part of the cell outside the nucleus.
Term
organelle
Definition
Organelles are structures that act like specialized organs "little organs".
Term
vacuole
Definition
A large, saclike, membrane-enclosed structures that store materials like water, salts, proteins, and carbohydrates.
Term
lysosome
Definition
A small organelles that break down macromolecules and other organelles that have outlived their usefulness that into small molecules that can be used by the rest of the cell; found in plant cells too
Term
cytoskeleton
Definition
Cytoskeleton are protein filaments that give eukaryotic cells shape and internal organization.
Term
centriole
Definition
Centrioles are found in animal cells, formed by tubulins, lcated near the nucleas and help organize cell division.
Term
ribosome
Definition
Ribosomes are small particles of RNA on which proteins are assembled and made.
Term
endoplasmic reticulum
Definition
Lipid components of the cell membrane are assembled along with proteins and other materials to be exported from cell and rough ER has ribosomes.
Term
golgi apparatus
Definition
Golgi Apparatus looks like a stack of flattened membranes which modifies, sorts, and packages materials from the ER for storage in cell or release from cell.
Term
chloroplast
Definition
Chloroplast captures energy from sun and turn it into food during photosynthesis.
Term
mitochondrion
Definition
Mitochrondrion are the power plants that convert chemical energy into compouds that are easier for the cell to use and is inherited from the ovum.
Term
cell wall
Definition
The cell wall is the strong supporting layer that surrounds membrane, give plants strength and rigity, supports
shapes, protects prokaryotes & plant cells. Animal cells do not have cell walls.
Term
lipid bilayer
Definition
The lipid bil;ayer gives the cell its flexible structure that forms a strong barrier between the cell and its surroundings.
Term
selectively permeable
Definition
Selectively permeable allows some substancees to pass across the membrane.
