tissues made of similar cells.
The model of the cell that states that cells make up all living things, come from preexisting cells, and perform the functions of living things.
A group of similar cells that work together.
A group of tissues that work together.
Eukaryotic cells have structure called

the structure that surrounds all cells and regulates what comes in and goes out
a rigid structure that surrounds and protects some cells
a slimy layer surrounding some bacteria that protects them from harmful substances and prevents their drying out
a whip-like structure that some cells use to propel themselves through their environment
the molecule that contains important information for making proteins and helps regulate many cellular processes
a structure that contains a cell’s DNA
a network of tubes in eukaryotic cells that help produce and transport proteins and other molecules throughout the cell
the organelle in eukaryotic cells that modifies many proteins and packages them into small, bubble-like structures called vesicles
a small structure that assembles proteins found in both prokaryotic and eukaryotic cells
several types of long, thin fibers anchored to various parts of the cell that help the cell maintain and change its shape
a small organelle in eukaryotic cells that act as the demolition crew within a cell

the movement of molecules through a membrane as a result of a concentration gradient
the movement of water across a semipermeable membrane
the movement of molecules across a membrane without the cell doing any work (i.e. osmosis, diffusion)
the movement of molecules across a membrane that requires the cell to do work

the molecule that a cell uses to power many processes in the cell that need chemical energy
the process in organisms of breaking down molecules to produce ATP
describes a process that does not use oxygen
a special cell that divides and matures into any type of cell needed by the body
