Plant vs. Animal

DirectionsDon’t worry it’s simple!

As you proceed you will find several icon buttons that will be used to guide you through this lesson. Below is an explanation of what each button will do for you. Later in the lesson, a buttons function may change, and you will be provided with new buttons. These changes will be explained as it becomes necessary for you to know them.

Back Home NextThis button will bring you back one slide.

This button will bring you back to several checkpoints. You will reach throughout the lesson.

This will bring you to the next slide in sequence.

OBJECTIVE 1:CELL STRUCTURE

Students will be able to identifySimilarities and differences

Between plant and animal cells.They will be able to recognizeAnd Identify cell organelles.

OBJECTIVE 2:ORGANELLE FUNCTION

Students will be able to make a directAnd clear connections between

Organelles and the purpose in the cell. They will understand the importance of Each organelle as a part to the whole.

The Story Of Cells

On January 1st, 1953 Robert C. Hooke discovered the cell while examining a

piece of cork under a microscope with a

50x magnification.

ThenIn 1839 Matthias Schleiden and Theodor Schwann came up with what is known today

as...

Cell theory includes

three parts.

1) All living organisms are composed

of cells

2) The cell is the basic unit of life.

3) Cells arise from pre-existing cells.

WHAT DOES THAT MEAN?WHY IS ANY OF THIS

IMPORTANT?

Both of these questions can beAnswered with one simple

Response.

ALL LIFE IS CREDITED TO THE EXISTENCE OF THE CELL!

Animal CellsThese cells differ from plant cellsIn a number of different ways:1) Structure

2) Appearence 3) Organelle Composition

Animal CellsAnimal cells do not have a cell wall

They are more free formed and round

No vacuole or choloroplasts presentContain lysosomes

Choose an organelle from thisCross section to learn about its function.

Cell Membrane

Centrisome

Cytoplasm

MitochondriaRibosome

Gogli Apparatus

Rough/ Smooth Endoplasmic Reticulum

Plant Cells Plant cells differ from animal cells

in a number of ways:

1) Structure

2) Appearance

3) Organelle Composition

Plant Cells These cells, unlike animal cells have a cell wall.

They are more angular, square, and rigid

They contain chloroplasts.

Many contain a large central vacuole.

They lack lysosomes.

Central Vacuole

MitochondriaRibosome

Gogli Apparatus

Rough/ Smooth Endoplasmic Reticulum

THE NUCLEUS A membranous organelle that contains the majority of the cells genetic material.

Here, we find the cells DNA.

It is also the control center of the cell, allowing it to control its contents.

Often we can find a dense area within which is responsible for ribosome production. This area is known as the nucleolis.

Cell MembraneComprised of a semi-permiable phospholipid bilayer. This

essentially means that the composition of the membrane allows for some things to pass in and out of the cell and for others to stay where they are.

Seperates the interior of the cell from its

environment.

Chloroplasts

Found only in plant cells. The site of photosythesis.

Used to help capture the suns energy usingThylakoid to store energy in

Molecules such as ATP or NADPH.

Cytoplasm: Plain and simply put cytoplasmIs the watery

substance thatFills in the space

between the nucleus

And the cell membrane.

Cell WallTough usually flexible. Fairly Rigid.

Offers protection.

Semi permiable.

Only forms in plant cells.

Central Vacuole

Plants are known to

have largeCentral

vacuoles.Often used in

storage of various

materials.

Small bubble within a cell

Enclosed with a lipid bilayer

Mitochondria

Often referred to as the powerhouse of the cell. Supplies the cell with the energy it needs to perform its other basic life processes. It does this through the process of Respiration. Respiration uses energy from food and the deoxidation of water molecules to form ATP molecules. These molecules are used in essentially every situation where work needs to be done by the cell…

!!!-RIBOSOMES-!!!

These little guys are the primary hosts for a process known as biological protein synthesis.

During this process, ribosomes essentially link amino acids to build proteins according to corresponding Rna triplicate codons.

Rough and Smooth Endoplasmic Reticulum

In the rough E.R. one can observe

Studded ribosomes throughout

The extensive maze of the organelle matrix. On

the smoothE.R. however, no

ribosomes are present. This part of the

E.R. is used to aid in cellular detoxification.

GOLGI APPARATUSPart of the cellular endomembrane

system, the Golgi apparatus packages proteins inside the cell before they are

sent to their destination; it is particularly important in the processing of proteins

for secretion.

The Centrosome houses an animal cell’s two centrioles. Centrioles play a crucial role in growth replication as they form the spindle fibers that assist in mitotic division.

Great workYou have completed the quiz Click the Quiz icon if you want

to restart! Let’s recap what we’ve learned!

What we Learned:

• How to distinguish plat from animal cells, and that although they have their differences they are at the same time very similar.

• The cell is the most basic building block of all life on Earth, and yet it is very complex.

• How to identify organelles and their functions as they each play a crucial and purposeful role to the overall well being of the cell.
