Flashcards in Cells Chapter 1 Deck (11):
1

cell

in biology, the smallest unit that can preform all life processes; cells are covered by a membrane and have DNA and cytoplasm.

2

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 environment.

3

organelle

one of the small bodies in a cell's cytoplasm that are specialized to preform a specific function.

4

nucleus

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.

5

cell wall

a rigid structure that surrounds the cell membrane and provides support to the cell.

6

ribosome

cell organelle composed of RNA and protein; the site of protein synthesis.

7

endoplasmic reticulum

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.

8

mitochondrion

in Eukaryotic cells, the cell organelle this is surrounded by two membranes and that is the site of cellular respiration.

9

golgi complex

cell organelle that helps make and package materials to be transported out of the cell.

10

vesicle

a small cavity or sac that contains materials in a eukaryotic cell.

11

Iysosome

a cell organelle that contains digestive enzymes.
