Cell Structures, Functions and Transport

ALWAYS REMEMBER!!!

Pro = No!Eu = Do!

Animal Cell

Nucleus

Nucleolus

Rough Endoplasmic Reticulum

Smooth Endoplasmic Reticulum

Ribosomes

Golgi Bodies

Mitochondria

Cell Membrane

Cytoplasm

Eukaryotic Cell Organelles and Function

Cell Membrane Nickname: “The Screen Door” Function:

Hold and protect the cell Control the movement of materials into

and out of the cell

Eukaryotic Cell Organelles and Function

Nucleus Nickname: “The Control Center” Function: Holds the DNA Parts:

1. Nucleolus: dark spot in the middle of the nucleus that helps make ribosomes

Eukaryotic Cell Organelles and Function

DNA Nickname: “The Info” Function

hereditary material that is passed on to you from your parents and is kept safe inside the Nucleus

Eukaryotic Cell Organelles and Function

Cytoplasm Nickname: “Jell-O” Function: A watery, gel-like material

in which cell parts move

Eukaryotic Cell Organelles and Function

Vesicle Nickname: “The Bag” Function:

Small membrane-enclosed sack that can store or transport substances

Eukaryotic Cell Organelles and Function

Ribosomes Nickname: “The Factory” Function: makes proteins Made in Nucleolus Found in all cells NOT membrane bound Smallest & most abundant

organelle in the cell

Eukaryotic Cell Organelles and Function

Endoplasmic Reticulum (ER) Nickname: “The Highway” Function: The internal delivery

system of the cell There are 2

types: Rough &Smooth

Eukaryotic Cell Organelles and Function

Golgi Bodies (Golgi Complex) Nickname: “The Post Office” Function: packages and transports

materials to different location inside/outside of the cell

Appearance: stack of pancakes

Eukaryotic Cell Organelles and Function

Lysosomes: circular shape but larger than ribosomes

Nickname: “The Trash Man” Function: to break down food into

particles the rest of the cell can use and to destroy old cells

Eukaryotic Cell Organelles and Function

Mitochondria Nickname: “The Powerhouse” Function: Breaks down food

molecules to release energy for the cells

Plant Cell

Cell Membrane

Vacuole

Chloroplasts

Cell Wall

Eukaryotic Cell Organelles and Function

Cell Wall Nickname: “The Fence” Function

Tough, rigid structure found outside of cell membrane that provide support for plants and fungi

Eukaryotic Cell Organelles and Function

Chloroplasts Nickname: “The Hulk” Function:

traps energy from the sun to produce food for the plant cell

Green in color because of chlorophyll, which is a green pigment

Eukaryotic Cell Organelles and Function

Vacuoles Nickname: “The Water Tower” Function: stores water & give

support This is what makes lettuce crisp

When there is no water, the plant wilts They are also found in animal cells, but

are smaller

PROKARYOTIC CELLS

Bacteria Cell

Only in Prokaryotic Cells

Gelatin-Like Capsule: Nick Name: “The Armor” Function: outer covering protects

the cell when it is eaten by other organisms

Allows Bacteria to survive and be dormant for many years until the conditions are right

Only in Prokaryotic Cells

Flagellum: Nickname: “The tail” Function:

Helps the cell move Used as a sensory organ
