| A | B |
| prokaryotic cell | cell without a nucleus or organelles (ex. bacteria) |
| eukaroyotic cell | cells with a nucleus and organelles |
| organelles | tiny structure in a cell with a specific structure |
| cell wall | supports and protects plant cells |
| cell membrane | "gate keeper" maintains homeostais, controls what goes in and out of a cell |
| selective permeabilty | some substances can go through it and some can't |
| cytoplasm | watery material in cell that holds organelles in place |
| nucleus | controls function of cell, contains DNA |
| mitochondria | "powerhouse" of cell, cellular respiration, makes ATP (energy) |
| endoplasmic reticulum | canal or highway system in cell that transports material in cell and to membrane |
| ribosomes | site of protein synthesis, some on ER, some float in cytoplasm |
| chromosomes | thread-like structures in nucleus composed of DNA & protein |
| vacuoles | large central sac in plants; small sac in animals; store food, waste, water |
| golgi complex | "post office and processing plant" stack of membranes that package newly synthesised products and send them back |
| lysosomes | "suicide sac" breaks down food, old cell parts, bacteria/only in animals |
| centrioles | used in cell division; cylinders that appear at 90 degree angles/only in animals |
| chloroplasts | contain green chlorophyll, used in photosynthesis/only in plants |
| nucleolus | small organelles in nucleus where ribosomes are made |
| nuclear membrane | membrane around the nucleus |
