GENBIO SUMMATIVE #1

Nucleus

Controls all the activities of the cells, a distinguishing feature between prokaryotes and eukaryotes

Bacterias

considered prokaryotic, while Amoeba, yeast, and paramecium are considered eukaryotic

Cell membrane

responsible for allowing substances in and out of the cell

Flagellum

helps prokaryotic cells move

Nuclear membrane

acts as a selectively permeable membrane that allows the passage of materials between the nucleus and the cytoplasm

Ribosome

the site of protein synthesis

Microtubules

supports the structure of the cell

Chloroplast

is responsible for energy production in plant cells, present in plant cells but absent in animals

Robert Hooke

coined the term "cell"

Cytosol

gel-like substance where all the other organelles are suspended

The theory of spontaneous generation

has been proven wrong because of the study of cells

Phospholipids

part of the cell membrane that is responsible for its fluid nature

Plasma membrane

found in all cells

Prokaryotic cell

a unicellular organism with circular DNA and ribosomes but no internal membranes
