CELL

CONCEPT

Cells are the smallest living unit

of an organism They have many sizes and shapes which relate to their function

PROKARYOTIC CELL

The first category is Prokaryotic cells aka cells without membrane bound structures

 Those can be found in bacteria and pond scum.

EUKARYOTIC CELL

 Those can be found in animals, plants, fungi and protists

EUKARYOTIC CELLS WITH PROKARYOTIC

CELL

The distinction between prokaryotes and eukaryotes is

considered to be the most important distinction among

groups of organisms Eukaryotic cells contain

membrane-bound organelles, such as the nucleus, while prokaryotic

cells do not Differences in cellular structure of

prokaryotes and eukaryotes include the presence of

mitochondria and chloroplasts, the cell wall, and the

structure of chromosomal DNA

Prokaryotes were the only form of life on Earth for

millions of years until more complicated eukaryotic

cells came into being through the process of evolution

 All cells are bound by cell membrane

but with plants, fungi, algae and most

bacteria they also have cell wall.

 The cell wall is made of cellulose , this

material help the cell wall for protecting

the cell and giving shape For cells with

cell walls the membrane is inside the

cell wall.

CELL WALL

 The cell membrane is the protective

layer for all cells.

 It separates the inside of the cells

from the environment It also

transforms food, oxygen and water

into the cell as well as transforms

waste product out of the cell.

CELL MEMBRANE

 The gelatin-like between the

Cell membrane and nuclear is

called Cytoplasm aka

Protoplasm This part of the cell

provides the environment for

organelle where they can work

and active.

CYTOPLASM

In fact this part of the cell is as

important as organelle

Beside the eukaryotic cells

can maintain and change their

shape by scaffolding-like

structure call Cytoskeleton

The Cytoskeleton includes

Microfilaments which are

made of protein , and

Microtubules , which are thin,

hollow tubes

In center of the cell which is

one of the most important

organelle is called nucleus

The nucleus contains DNA, or

genetic material DNA

dictates what the cell is going

to do , and it’s going to do it

NUCLEAR MEMBRANE

The layer around the nucleus is

Nuclear Membrane which is

Cytoplasm

It also decides what is go in and

what is go out to the nucleus The

Nucleus also contains a nucleolus,

which a structure where ribosomes

are made Finally the material that

contains genetic code is called

Chromatin Made of DNA and

Protein the Chromatin will shrink

when the cell is ready to divide
