animalcule

Very Small animal invisible to the naked eye

Cell Membrane

container of the cytoplasm around the cell

Cell Wall

thicker, tougher than membrane; found only in plants

Diffusion

movement of water in a cell

isotonic

same concentration both sides

hypertonic

side with higher concentration

hypotonic

side with lower concentration

Osmotic Pressure

force to transfer water through a semi permable membrane

Facilitated Diffusion

the lipid bilayer will only let molecules of the right size through

Active Transport

moves solute from areas of high concentration to low concentration

Endocytosis

the transport of solid matter or liquid into a cell by means of a coated vacuole or vesicle

Phagocytosis

endocytosis of larger cells

exocytosis

endocytosis out of the cell

Chromatin

grainy material in nucleus, makes chromosomes

Nucleolus

assembles ribosomes

nuclear envelope

lipid bilayer

microtubles

hollow tubes of protein, builds cilia, flagela and centrioles

microfilaments

moves organelles inside cell

rough endoplasmic reticulum

studded with ribosome; assembles proteins

smooth endoplamic reticulum

no ribosomes; assembles lipids
