Eukaryotic Cells

1
Eukaryotic Cells

• The Inside Story

2
What two things help scientist see cells?

• Better magnification
• Staining

3
Cell Membrane

• All cells have this made from lipids.
• Keeps cytoplasm in
• Allows nutrients into the cell and lets waste out
• Interacts with things outside of the cell

4
Cell Wall

• Only plants including algae
• Made of cellulose
• Provides strength and support
• Prevents membrane from tearing
• Why do trees stand up?

5
Nucleus

• The largest organelle
• Cells Brian/Library
• Means kernel or nut
• Stores DNA
• Nucleolus
• makes ribosomes which make protein
• Why is it called the cells library or brain?

6
Ribosomes

• Ribosomes function as factories to make proteins
• Proteins are the building blocks of all cells
• Ribosomes release some proteins through the wall
  of the ER
• Can a cell survive without ribosomes?

7
Endoplasmic Reticulum

• ER
• Also known as the highway
• Membrane covered compartment/tunnels
• Internal delivery system
• Makes lipids for the membrane

8
The Cells Power Plant

• Cells need energy to function
• Mitochondria makes ATP
• Needs oxygen
• Has two membranes
• Chloroplasts
• Only plants and algae
• Chlorophyll makes them green
• Photosynthesis

9
Golgi Bodies/Apparatus/Complex

• The Golgi Complex
• Named after Camillo Golgi
• Located near the membrane
• Processes
• Packages
• Transports
• food and waste
• lipids and proteins from the ER
• Golgi complex pinches off a piece into a vesicle

10
Vacuoles and Vesicles

• Move throughout the cell
• Storage compartments or packages
• Vesicles store food and waste
• Vacuoles store water

11
Plant Vacuole

• Plants largest organelle in a plant
• Store water and other lipids
• Needs water for photosynthesis
• How do you refresh lettuce?

12
Lysosomes

• Lysosomes are the BOMB
• Packages of destruction
• A tadpoles tail to disappear
• Lysosomes special vesicles
• Destroy worn out organelles
• Get rid of waste
• Protect the cell from foreign matter

13
Plant Cell

• Chloroplast
• Large vacuole
• Cell wall
