Nucleus

a part of the cell containing DNA and RNA and responsible for growth and reproduction, SOME Genes are founds in the Mitochondria and Chloroplasts

Prokaryote

single celled

no nucleus

no membrane inside cell

Eukaryote

Cells that contain an nucleus and membrane-bound organelles such as endoplasmic reticulum, chloroplasts, mitochondria and Golgi apparatus

Organelle

is a small body in a cell's cytoplasm that is specialized to perform a certain function -- Cell Organs

Chloroplast

GREEN BLOBS....organelle bounded by a double membrane containing the enzymes and pigments that perform photosynthesis; occur only in eukaryotes.

Mitochondria

Organelle responsible for producing energy in animals, plants, and fungi --- breaks down food to make ATP "ENERGY" (CELL RESPIRATION)

"Powerhouse" of the cell

cell wall

Structure found in prokaryotic cells and eukaryotic plant cells that provides support and protection for the cell

Cell membrane (plasma membrane)

Outside layer of most eukaryotic cells --- "Bouncer," controlling what enters and leaves the cell

Diaphragm

LEVER OR KNOB -- regulates the amount of light that enters the body tube of a microscope?

microscope objective lens

low, medium, and high power

ocular lens

Eye Piece Lens

fine adjustment knob

this knob sharpens an image under low and medium power

transparent

easily seen through, as in glass
