Eukaryotic Cells
Robert Hook
Contribution to Science:
Came up with the word “cells”
Anton van Leeuwenhoek
Contribution to Science:

Cell Theory
• All living things are composed of cells
• Cells are the basic units of structure and
function in living things
• New cells are produced from existing
cells
Eukaryotic Cell
Eukaryotic Cell
Definition:
A cell that contains a NUCLEUS
2 Types of Eukaryotic Cells
1) Animal Cell
2) Plant Cell
Parts of the Eukaryote
Cell Membrane
Encloses contents of entire cell
Cell Membrane
Cytoplasm
Gel like region that holds the
organelles and nucleus in place
Organelles “Little Organs”
Specialized structures within a cell
Organelles within an Animal
Eukaryotic Cell
Nucleus
Stores the cell's DNA
Coordinates the cell's activities (growth,
metabolism, protein synthesis, cell
division)
Endoplasmic Reticulum
Transports materials
ER
Ribosomes
Where proteins are made
Look like small
specks throughout
the cytoplasm or ER
Golgi Apparatus
Receives, modifies, and ships out,
proteins from the ER, within or outside
the cell
Mitochondria
Converts chemical energy stored in food
into usable energy for the cell
Lysosome
Break down the
cell’s food, waste,
and damaged
organelles.
Vacuoles
Stores materials such as water, salts,
proteins, and carbohydrates until the
cell needs them
