Unit 3 Cell/Transport Quizlet

Homeostasis

The body in balance or without disruption

passive transport

movement across a cell membrane without energy

Diffusion

Higher to lower concentration movement

Osmosis

diffusion of water

cell membrane

the structure around eukaryotic cells that allows things to move in and out of the cell

Pores

tiny areas where things can move in and out

selectivly permeable

only cetain substances can enter

phospholipid bilayer

A double layer of phospholipids that makes up organelle membranes.

transport proteins

proteins that transport substances in and out of the membrane

concentration gradient

the differences of a substances concentration from a distance

osmotic pressure

pressure aplied to stop osmosis

Equilibrium

the point at which everything is in balance

active transport

the movement through a cell membrane using energy

Photosynthesis

the making of energy using the suns energy

cellular respiration

the process of making atp in animal cells with the mitochondria

Chloroplast

the organelle used in the process of photosynthesis

Mitochondria

the power house of the cell(makes energy for eukaryotic cells)

Nucleus

the protective layer of eukaryotic cells that surrounds dna

Golgi body

packages proteins in the cell

Vesicle

transports proteins around the cell

Endoplasmic Reticulum

gateways of the cell that transports things from different parts of the cell

Lysosomes

the oganelle that breaks down waste

cytoplasm

the fluid that fills up the empty areas of a cell
