Virus
Tiny non-living structure that depends on a host cell to reproduce
Cell wall
Supports and protects cell membrane in plant cells
Prokaryotic
Simple cell without organelles
Organelles
Specialized functional bodies with in the cytoplasm of the cell
Homeostasis
Regulation of conditions within a cell which allows for stable equilibrium
Vacuole
Organelle that holds water; particularly large in plant cells
Eukaryotic
Complex cell containing organelles with specific functions
Nucleus
Controls the cells activities; contains the cell's DNA
Hyoertonic
Solution with a relatively higher solute concentration (such as salt)
Chloroplast
Contains chlorophyll for photosynthesis in plant cells
Hypotonic
Solution with a relatively lower solute concentration (such as salt)
Passive transport
Diffusion if a substance across a cell membrane requiring no energy
Nucleic acids
A biological molecule, such as DNA or RNA, that contain genetic coding
Cytoplasm
Suspends organelles in a eukaryotic cell; enclosed by the cell membrane
Host cell
a particular type of cell that is targeted by a virus for reproduction
Diffusion
The tendency of a substance to move from a higher concentration to lower concentration
Active transport
Movement of a substance across a cell membrane requiring the use of energy
Mitochondria
Organelle responsible for breaking down food into energy
Cell membrane
Controls what leaves and enters the cell; maintains homeostasis
