Chapter 1 Book 2 Flashcards
in biology the smallest unit can preform all life processes;cells are covered by a membrane and have DNA and Cytoplasm
Cell
a phospholipid layer that covers a cells surface acts as a barrier of the cell and the cells environment.
Cell Membrane
one of the small bodies in the cells cytoplasm and have special funtions
organelle
in a Eukaryota cell, a membrane bound organelle that contains the cells DNA
Nucleus
an organism made up of cells that have a necleus enclosed by a membrane
Eukaryote
a rigid structure that surrounds the cell membrane and provides support to the cell
cell wall
cell organelle composed of RNA and protein
Ribosome
an organism that consists of a single cell that does not have a necleus
Prokaryote
a system of membranes that is found in a cells cytoplasm and that assist in the production, processing, and transport of proteins and in the production of lipids.
Endoplasmic Reticulum
in Eukaryota cells the cell organelle that is surrounded by two membranes and that is the site of cellular respiration
Mitochondrion
cell organelle that helps make and package materials to be transported out of the cell
Golgi Complex
a small cavity or sac that contains materials in a Eukaryotic cell
vesicle
a cell organelle that contains digestive enzymes
Lysosome
a group of similar cells that preform a common funtion
tissue
a collection of tissue that carry out a specialized function of the body
