cell parts Flashcards
cell
in biology the smallest unit that can perform all life processes cells are covered by membrane and have DNA and cytoplasm
nucleus
in a eukaryotic cell, a membrane-bound organelle that contains the cell DNA and that has a role in processes such as growth metabolism and reproduction
cytoplasm
fluid surrounding them make up the cytoplasm
cell membrane
a phosphoilpid layer that covers a cell surface acts as a barrier between the inside of a cell environment
cell wall
a rigid structure that surrounds the cell membrane and provides support to the cell
mitochondrion
in euraryotic cells the cell organelle that is surrouned 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
the organelle that processes and transports proteins and other materials out of a cell
endoplasmic reticulum
the organelle that makes lipids breaks down drugs and other substances and packages proteins for golgi complex
ribosome
cell organelle composed of RNA and protein the site of protein synthesis
llysosome
a cell organelle that contains digestive enzymes
vacuole
a cell or vesicle
organelle
one of the small bodies in a cell cytoplasm
prokaryote
an organism that consits of a single cell that does not have a nucleus
