Flashcards in Cells Chapter 1 Deck (11):
in biology, the smallest unit that can preform all life processes; cells are covered by a membrane and have DNA and cytoplasm.
a phospholipid layer that covers a cell's surface; acts as a barrier between the inside of a cell and the cell's environment.
one of the small bodies in a cell's cytoplasm that are specialized to preform a specific function.
in a Eukaryota cell, a membrane-bound organelle that contains the cell's DNA and that has a role in processes such as growth, metabolism, and reproduction.
a rigid structure that surrounds the cell membrane and provides support to the cell.
cell organelle composed of RNA and protein; the site of protein synthesis.
a system of membranes that is found in a cells cytoplasm and that assist in the production, processing, and transport of proteins and the production of lipids.
in Eukaryotic cells, the cell organelle this is surrounded by two membranes and that is the site of cellular respiration.
cell organelle that helps make and package materials to be transported out of the cell.
a small cavity or sac that contains materials in a eukaryotic cell.
