cell parts Flashcards
the smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane.
cell
a dense organelle present in most eukaryotic cells, typically a single rounded structure bounded by a double membrane, containing the genetic material.
Nucleus
the material or protoplasm within a living cell, excluding the nucleus
cytoplasm
the semipermeable membrane surrounding the cytoplasm of a cell
cell membrane
a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi, and bacteria.
cell wall
an organelle found in large numbers in most cells
mitochondria
a plastid that contains chlorophyll and in which photosynthesis takes place
Chloroplast
a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane
Endoplasmic reticulum
a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells
Ribosome
an organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in a membrane.
Lysosome
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Vacuole
any of a number of organized or specialized structures within a living cell
Organelle
a microscopic single-celled organism that has neither a distinct nucleus with a membrane nor other specialized organelles
Prokaryote
an organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus
Eukaryote
An aggregation of morphologically similar cells and associated intercellular matter acting together to perform specific functions in the body
