The Structure and Function of Cells
Converts light energy from the sun into chemical energy.
Chloroplast
The internal balance of a system that keeps conditions stable.
homeostasis
A factor that determine if a particle can be passively transported across a cell membrane
particle size, particle shape, particle polarity, membrane composition
The fluid in which the organelles are suspended?
cytoplasm
Not found in animal cells, provides strength and rigidity to the cell.
cell wall
The diffusion of a solvent through a semipermeable membrane from an area of low concentration of solutes to an area of high concentration.
osmosis
Requires energy for molecules to move across a cell membrane.
active transport
A cell without membranes around the organelles.
prokaryotic
The powerhouse of the cell transforms sugar into useable energy.
mitochondria
When solute particles spread from an area of high concentration to an area of lower concentration.
diffusion
Energy is used to surround a molecule by a cell membrane and pinches it off into the cell.
endocytosis
Genetic material of the nucleus.
chromatin
Found in all cells and protects the cell and allows certain materials to move through it.
cell membrane
Produces movement of water out of the cell that causes it to shrivel.
hypertonic
Energy is used to releases molecules to the outside of the cell.
exocytosis
Organelle that is responsible to make protein.
ribosome
Control center of the cell only found in eukaryotic cells.
nucleus
Producing movement into a cell that causes it to swell.
hypotonic
The cell applies energy to this before the protein will move the substance across the membrane.
transport protein
Long whip-like structure that propels the cell.
flagellum
