Let’s Look at structures in Animal Cells First

Cell Membrane

This structure, in animal and plant cells, holds the parts of the cell inside and controls the movement of materials in and out of the cell.

The Nucleus

• Controls most activities in the cell

• Contains all genetic information in the form of DNA.

Nucleus DNA

Chromatin

Chromosome

Nucleolus

Nuclear Envelope

It is like the “Brain” of the cell

Cytoplasm

This is the jelly-like substance in which the structures inside the plant and animal cells float and move

Endoplasmic Reticulum

– 2 Types:

1.Rough ER: – Rough appearance because it has ribosomes– Function: helps make proteins, that’s why it

has ribosomes

2.Smooth ER:– NO ribosomes– Function: lipids; and detoxifies

Page 7: Parts of A Cell Everything on Earth is made up of atoms and molecules. So what makes you different from something like a rock? You, like all living things,

Endoplasmic Reticulum

• Series of folded membranes that form sacs or tubes

• Rough ER has ribosomes attached

Ribosomes

• Makes proteins in the cell

• May be free in cytoplasm or attached to ER

Page 10: Parts of A Cell Everything on Earth is made up of atoms and molecules. So what makes you different from something like a rock? You, like all living things,

Golgi Bodies

• Saclike membranes• Modifies proteins

• Sorts and packages used for storing/ packages

• “Post Office”

VacuoleTemporary storage area for food and waste.

Plant cell—one large CENTRAL VACUOLE

Animals-fewer, smaller. t

It is like a pantry.

Lysosomes

Garbage Disposal

(“suicide sacs)

• Contain digestive enzymes to digest unwanted particles

• Help white blood cells to destroy bacteria

The Energy Tranformers

• Mitochondria

• Chloroplast

Page 14: Parts of A Cell Everything on Earth is made up of atoms and molecules. So what makes you different from something like a rock? You, like all living things,

Mitochondria

• Energy producers—ATP- releases energy from digested food

• Powerhouse of the cell

• Sausage-shaped

• Many mitochondria in muscle cells

Centrioles

• -microtubules form here for cell division

Page 16: Parts of A Cell Everything on Earth is made up of atoms and molecules. So what makes you different from something like a rock? You, like all living things,

These are found in plants—not animals

• Cell Wall

• Chloroplast

Page 17: Parts of A Cell Everything on Earth is made up of atoms and molecules. So what makes you different from something like a rock? You, like all living things,

Cell Wall

This structure is not found in animal cells.

Made of cellulose in plants

Permeable-not selective

Provides support and protection for the plant cell.

Chloroplast

photosynthesis plant makes food.
