Group Activity

• Identify cell you are given Plant or Animal
• Label cell organelles using the word bank
• Each person must describe the function of each
  organelle on a separate piece of paper.
• Nucleus
• Mitochondria
• Chloroplast
• Cell Membrane
• Cell Wall

• Vacuole
• Cytoplasm
• Ribosomes
• Endoplasmic Reticulum
• Golgi Bodies

Plant vs. Animal
5
Cell Membrane

• Both plant and animal cells
• Description
• Inside cell wall of plant
• Outer layer for animal
• Selectively permeable
• Function
• Support and protection
• Controls what enters and leaves the cell
• Maintain homeostasis
• Barrier between cell and outside environment

6
Cell Wall

• Only found in plant cells
• Description
• Outer layer
• Rigid, strong stiff
• Made of cellulose.
• Functions
• Support and protection
• Allows water, oxygen, and carbon dioxide in and
  out of cell.

7
The Nucleus

• Both plant and animal
• Description
• Large oval structure
• Function
• Controls most activities in the cell
• Contains all genetic information in the form of
  DNA.

8
Cytoplasm

• Both plant and animal
• Description
• Clear, thick, jellylike fluid within cell that
  contains all organelles
• Inside cell membrane
• Function
• Allows movement of materials throughout the cell
• Supports and protects organelles

9
Endoplasmic Reticulum

• Both plant and animal
• Description
• Series of folded membranes that form sacs or
  tubes
• Function
• carries materials through cell
• lipid components of cell membrane are assembled.
• modify proteins made by ribosomes
• Rough ER has ribosomes attached

10
Ribosomes

• Both animal and plant
• Also in prokaryotes!
• Description
• Small bodies, free or attached to ER
• Function
• Makes proteins in the cell
• May be free in cytoplasm or attached to ER
• Proteins are vital to life- all cells must
  produce them

11
Golgi Bodies

• Both plant and animal
• Description
• Saclike, folded membranes
• Function
• modifies, sorts, and packages proteins
• prepares cell components for storage or movement
  out of cell
• Cells that make saliva or mucus have many Golgi
  bodies

12
Mitochondria

• Both plant and animal
• Description
• bean-shaped with inner membranes
• Function
• breaks down sugar molecules into energy
• Energy producers
• Powerhouse of the cell
• Many mitochondria in muscle cells

13
Chloroplast

• Only plant cells
• Description
• Green, oval usually containing chlorophyll
• Double membrane
• Function
• uses energy from sun to make food for the plant
  (photosynthesis)

14
Vacuoles

• Plants have few that are large
• Animals have small vacuoles
• Description
• Fluid filled sacs
• Function
• Store food, water, or waste materials
• In plants the pressure adds support for heavy
  leaves
• Plant need to store lots of food!

15
Lysosomes

• Plant uncommon
• Animals - common
• Description
• Small, round with a membrane
• Function
• Contain digestive enzymes to digest unwanted
  particles
• Digests old cell parts
• Help white blood cells to destroy bacteria

Summarize

• What did you notice about all of the plant cells?
• What did you notice about all of the animal cells?

Cell Specialization Benefit of Multicellular
Organisms

• How are the plant cells that are found in the
  leaves of a tree different from the plant cells
  that are found in the roots of the tree?
• How are our skin cells different from our muscle
  cells?
