movement of molecules across the cell membrane without using cellular energy

movement of materials against a concentration difference

relatively constant internal physical and chemical conditions that organisms maintain

process by which particles tend to move from an area where they are more concentrated to an area where they are less concentrated

facilitated diffusion

process of diffusion in which molecules pass across the membrane through protein channels in the cell membrane

water channel protein in a cell membrane

diffusion of water through a selectively permeable membrane

when the concentration of two solutions is the same

when comparing two solutions, the solution with the greater concentration of solutes

when comparing two solutions, the solution with the lesser concentration of solutes

pressure that must be applied to prevent osmotic movement across a selectively permeable membrane

a membrane protein that uses energy to move ions or molecules across a cell membrane against their concentration gradient.

the process of bringing material into a cell by means of parts of the membrane folding in, or forming pockets resulting pocket breaks away from the cytoplasmic side of the cell membrane, forming a vesicle or vacuole in the cytoplasm

type of endocytosis in which extensions of the cell surround a particle and package it within a food vacuole

type of endocytosis Tiny pockets form along the cell membrane, fill with liquid, and pinch off to form vacuoles "CELL DRINKING"

the membrane of a vesicle or vacuole fuses with the cell membrane, forcing the contents of the vacuole out of the cell

group of similar cells that perform a particular function

group of tissues that work together to perform closely related functions

group of organs that work together to perform a specific function

a living thing that possesses a set of characteristics, including cellular organization, metabolism, homeostasis, growth and development, response to environmental stimuli, and reproduction

on or in a cell, a specific protein that receives chemical signals from molecular messengers, such as hormones

to pass through a substance, like a biological membrane, by diffusion or osmosis.

ATP (adenosine triphosphate)

the cell's "energy currency" or a "rechargeable battery" a molecule that stores and releases energy by breaking the high-energy bonds between its phosphate groups
