Cell Structure and Function

the basic unit of life

• cell

• organ

• tissue

• organelle

States that: 1. All living organisms are composed of cells. They may be unicellular or multicellular. 2. The cell is the basic unit of life. 3. All cells come from pre-existing cells

• cell theory

• plant cell

• solution

single-celled organism lacking a nucleus and other membrane-bound organelles; for example cyanobacteria

• plant

• animal

• prokaryote

• eukaryote

organism whose cells contain a nucleus and other membrane-bound organelles; for example ameoba

• plant

• animal

• prokaryote

• eukaryote

organelles in eukaryotic cells that are surrounded by a lipid bilayer membrane

• membrane bound organelles

• muscle cells

• concentration gradient

• nuclear envelope

a lipid bilayer that surrounds the nucleus in eukaryotic cells

eukaryote

• plant

• animal

• fungus

• all of them are eukaryotes

process by which organisms maintain a relatively stable internal environment

• concentration gradient

• cellular respiration

• homeostasis

• active transport

phospholipid bilayer that surrounds all cells and regulates what enters and leaves the cell

• nuclear membrane

• cell membrane

• membrane bound organelles

• cell wall
