Cell Theory and Cell Organelles

Surrounds the outside of ALL cells!

Made of two layers (known as the phospholipid bilayer)

Controls what goes in and out of the cell

Have hydrophilic (likes water) heads and hydrophobic (dislikes water) tails

Threadlike fibers

Made of proteins

Give the cell shape

Can also move organelles around

Jelly-like substance

Mainly made up of water

Holds everything in place

• cytoskeleton

• cytoplasm

• cell membrane

• mitochondria

Contains genetic material (DNA)

Surrounded by a nuclear envelope/membrane with pores that control what goes in and out

Protects the DNA that controls the activities of the cell

• nucleolus

• chloroplast

• nucleus

• centrioles

NGSS.MS-LS1-2

Inside of the nucleus

Makes rRNA which make up ribosomes

• Nucleus

• Cytoskeleton

• Flagella

• Nucleolus

Made of proteins and rRNA

Located on Rough ER and floating in cytoplasm

Make proteins

• ribosomes

• smooth endoplasmic reticulum

• nucleus

• cytoplasm

NGSS.MS-LS3-1

Has ribosomes on the surface

Hugs the nucleus

Makes proteins

Packages them for secretion

• Smooth Endoplasmic Reticulum

• Rough Endoplasmic Reticulum

• Nucleus

• Golgi Apparatus

Tags

NGSS.MS-LS1-2

No ribosomes on surface

Makes lipids (membrane)

• Smooth Endoplasmic Reticulum

• Rough Endoplasmic Reticulum

• Golgi Apparatus

• Nucleus

Tags

NGSS.MS-LS1-2

Folded membrane

Gets vesicles of protein from the ER

Processes, sorts, and ships proteins where needed

• Rough Endoplasmic Reticulum

• Vesicle

• Lysosome

• Golgi Apparatus
