PLAY
Nucleus
Controls cell activities, contains DNA (genetic information)
Nucleolus
Located inside of nucleus, produces ribosomes
Ribosome
Where proteins are made, most numerous organelle
Rough Endoplasmic Reticulum
Site of protein synthesis, has ribosomes attached to it
Smooth Endoplasmic Reticulum
Has no ribosomes in its membrane, synthesizes lipids and proteins
Golgi Apparatus
stack of membranes in the cell that modifies, sorts, and packages proteins from the endoplasmic reticulum
Lysosome
a cell organelle that contains digestive enzymes, only in animal cells
Nuclear Membrane
controls what goes in and out of the nucleus
Cilia & Flagella
Hair-like structures found in animal cells that assist in movement
Centrioles
Organelles that assist in cell division, only in animal cells
Chloroplast
Traps solar energy and converts it to glucose in the process of photosynthesis, only in plants
Mitochondria
Also called the powerhouse of the cell, converts (breaks down) glucose into useable energy
Vacuole
Stores food, water and digestive enzymes
Cell Wall
strong wall outside a plant cell's plasma membrane that protects the cell and maintains its shape
Cytoplasm
a jellylike fluid inside the cell in which the organelles are suspended, provides support to the cell
Cell (Plasma) Membrane
Controls what enters and exits the cell, double layer of lipids, essential for maintaining homeostasis
