cell parts Flashcards
(20 cards)
cell
In biology, the smallest unit that can perform all life processes; cells are covered by a membrane and contain DNA and cytoplasm.
Nucleus
in a eukaryotic cell, a membrane-bound organelle that contains the cell’s DNA and that has a role in processes such as growth, metabolism, and reproduction.
Cell Wall
A rigid structure that surrounds the cell membrane and provides support to the cell.
cell membrane
a phospholipid layer that covers a cell’s surface and act’s as a barrier between the inside of a cell and the cell’s environment.
Organ
a collection of tissues that carry out a specialized function of the body.
Organ system
a group of organs that work together to perform body functions.
Organism
a living thing; anything that can carry out life processes independently.
Tissue
A group of similar that perform a common function.
organism
a living thing; anything that can carry out life processes independently.
Structure
The arrangement of parts in an organism.
Eukaryote
an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes includes ,animals, plants and fungi but not archaebacteria or eubacteria.
Golgi complex
cell organelle that helps make and package materials to be transported out of the cell.
Endoplasmic reticulum
a system of membranes that is found in a cell cytoplasm and that assist in the production, processing and transport of proteins.
Vacoule
a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
a small cavity or space in tissue, especially in nervous tissue as the result of disease.
Chloroplast
(in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
mitochondrion (plural mitochondria.)
The mitochondrion (plural mitochondria) is a double-membrane-bound organelle found in most eukaryotic organisms. Some cells in some multicellular organisms may, however, lack them (for example, mature mammalian red blood cells).
Lysosome
a cell organelle that contains digestive enzymes.
Prokaryote
an organism that consist of a single cell that does not have a nucleus.
Ribosome
a cell organelle composed of RNA and protein; the site of protein synthesis.
Organelle
one of the small bodies in a cell’s cytoplasm that are specialized to perform a specific function
