cell parts Flashcards
cell
cell in biology, the smallest unit that can perform all life processes; cells are covered by a membrane and have 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
cytoplasm
the fluid inside a cell
cell membrane
a phospholipid layer that covers a cell’s surface; acts as a barrier between the inside of a cell and the cell’s evrionment
cell wall
a rigid structure that surrounds the cell membrane and provides support to the cell
mitochondrion
in eukaryotic cells, the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
Chloroplast
the organelle that uses the energy of sunlight to make food
Golgi complex
cell organelle that helps make and package materials
Endoplasmic reticulum
a system of membranes that is found in a cells cytoplasm and assists in the production, processing , and transport of proteins and in the productions of lipids
Ribosome
cell organelle composed of RNA and Protein; the site of Protein synthesis
Lysosome
a cell organelle that contains digestive enzymes
Vacuole
the organelle that stores water and other nutrients
Organelle
one of the small bodies in a cell’s cytoplasm that are specialized
Prokaryote
an organism that consists of a single cell that does not have a nucleus
Eukaryote
an organism made up of cells that have a nucleus enclosed by a membrane; eukaryotes include animals, plants, and fungi, but not archaebacteria or eubacteria
