Cell Structures of Animal Cells

NAME

GRAPHIC

FUNCTION

 

 

Plasma (cell) Membrane

 

 

cell membrane

Semi-Permeable

Lipid Bilayer

double layer of phospholipids

& proteins

 

There is NO CELL WALL

 

Cytoplasm

 

All of the cellular material between the plasma membrane and the nucleus.

 

cytosol: The fluid,

cytoplasmic organelles,

inclusions: glycogen granules, lipid droplets

 

 

Nucleus

 

cell nucleus

The nucleus contains the genetic material and functions as the cells control center.

 

It contains the instructions to build the body’s proteins.

 

Nucleoli

Spherical bodies within the nucleus

This is the site of ribosome production.

Nuclear Envelope

Double membrane that contains nuclear pores

Keeps DNA in the nucleus & lets mRNA out

Chromatin

Chromatin is composed of DNA and histone proteins

Genetic material

 

 

 

 

Mitochondria

 

mitochoondria

 

Mitochondria are the powerhouse of the cell

 

It is where respiration takes place and ATP is produced

Golgi Apparatus

all called:

 Golgi body

and

Golgi complex)

 

glogi apparatus

 

It functions to modify, concentrate, and package proteins.

 

Transport vesicles bud of and move to the plasma membrane and discharge the contents.

 

 

Rough Endoplasmic Reticulum

rougn endoplasmic reticulum

 

Studded with ribosomes;

 

Functions to secrete proteins and phospholipids.

 

 

Smooth Endoplasmic Reticulum

smooth endoplasmic reticulum

Some of its functions include:

a). lipid metabolism

b). synthesis of steroid base hormones

c). detoxification of drugs

d). breakdown of glycogen

e). absorption and transportation of fats.

 

 

Ribosomes

ribosomes

 

 

Ribosomes are the sites of protein synthesis

 

 

 

Cytoskeleton

cytoskeleton

Microfilaments

Involved in cell motility

Intermediate Fibers

Act as guy wires to resist pulling forces.

Microtubules

Determine the overall shape of the cell.

 

 

Centrioles

centrioles

 

 

During mitosis the centrioles line up on the opposite ends of the cell and organize the tubules that pull the chromosomes apart

 

 

Cilia & Flagella

cilia/flagella

 

Cilia

Whip-like motile cellular extensions that usually occur in large numbers.

 

Flagella

Are long cellular projections

 

Lysosomes

lysosomes

 

Digests particles, degrades nonfunctional organelles, and non-useful tissues
