eukaryote

A cell that contains a true nucleus and membrane bound organelles

prokaryote

A unicellular organism that lacks a nucleus and membrane bound organelles

organelle

specialized cell structure that performs a specific function with in the cell

cytoplasm

the liquid portion of the cell in which all organelles are found

nucleus

the control center of the cell

nuceolus

a region of the nucleus that produces ribosomes (rRNA)

nuclear envelope

A double membrane that surrounds the nucleus in the cell

chromatin

long strands of DNA found in the eukaryotic cell nucleus; condense to form chromosomes

chromosome

condensed coils of genetic material formed from chromatin as a cell prepares to divide

ribosome

An organelle that functions in the synthesis of proteins

endoplasmic reiculum

pathways to transport materials throughout the cell, helps process proteins and move them to the golgi

golgi body

organelles that package cellular materials and transport them within the cell or out of the cell

lysosome

cell organelle filled with enzymes needed to break down certain materials in the cell

mitochondria

Powerhouse of the cell, organelle that is the site of ATP (energy) production

vacuole

storage structures for food, water, minerals, waste, very large in plants due to the storage of water reserves

chloroplast

organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy

cytoskeleton

a network of fibers that holds the cell together, helps the cell to keep its shape, and aids in movement

centriole

structure in an animal cell that helps to organize cell division

cell membrane

controls what comes in and out of the cell

cell wall

strong layer around the cell membrane in plants, algae, and some bacteria
