internal membrane system found in eukaryotic cells; place where lipid components of the cell membrane are assembled

organelle in cells that modifies, sorts, and packages proteins and other materials from the endoplasmic reticulum for storage in the cell or release outside of the cell

cell organelle that stores materials such as water, salts, proteins, and carbohydrates

cell organelle that breaks down lipids, carbohydrates, and proteins into small molecules that can be used by the rest of the cell

network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement

cell organelle that converts energy from sunlight into chemical energy through the process of photosynthesis

cell organelle that converts the chemical energy stored in food into compounds that are more covenient for the cell to use (POWER HOUSE)

organism whose cells contain a nucleus

unicellular organism that lacks a nucleus

cluster of chlorophyll and proteins found in thylakoids

movement of molecules from high concentration to low concentrations

movement of particles across a cell membrane without the use of energy by the cell

uses energy to move materials into a area of higher concentration

diffusion of water through the selectively permeable membrane

when a cell uses energy to surround a particle and enclose the particle in a vesicle to bring the particle into the cell

when particles are enclosed in a vesicle and released from a cell
