Term
Function of Nucleus
Definition
Control center of the cell
Term
Function of Golgi Apparatus
Definition
Packages up the protein
Term

Function of Cell Membrane

Definition
Semi- permeable; it controls what moves in and out of the cell
Term

Function of Endoplasmic Reticulum ( smooth and Rough)

Definition

Transport system in the cell

*rough ER has ribosomes on it-produces proteins

*smooth ER has no ribosomes-produces lipids

Definition

Small Circular structure in the nucleus, involved in the making of ribosomes

Term
Function of Cytoplasm
Definition
The region between thr nucleus and the plasma membrane
Term

Function of Microtubules

Definition

Straight hollow tubes of protein/ provides tracks for organelles

Term

Function of Cytoskeleton

Definition
a network of microfilaments and microtubules that helphold the cell shap and move organelles around

Function of Central Vacuole

Definition
Term

What do Ribosomes make?

Definition

Produces Proteins

Term
Function of Flagella
Definition
an organelle with a single whip like structue
Term

Definition
  • Prokaryotic- lacks a nucleus and most other organelles *bacteria
  • Eukaryotic- has nucleus surrounded by own membrane and other internal organelles
Term
Cell Theory
Definition
  • all living things are made of cells
  • cells are basic structure pf living things
  • all cells come from pre existing cells
