CELLS
-

-

All living things are made up of cells
...
They are large
of sizes between 10 micrometres to 100 micrometres
...
They have a nucleus which contains genetic material
...
They do not have a
nucleus
...
Also they contain
plasmid
...

Prokaryotes are single celled organisms
...

Cells are specialised to carry out different functions
...

Cell Membrane: controls the passage of things going into and out of the cell
...
It also contains receptor molecules
...
Chemical reactions take place here
...
It also contains dissolved nutrients,
salts, and organelles
...
e chromosomes), which determines the
function and the appearance of the cell
...
It
also has information to make new cells or organisms
...
Energy is ATP which is formed when glucose breaks down
...
It is visible by the light microscope but not
clear enough
...
This is where proteins are
made
...


Plant Cell:
Some of the content is like the animal cell but there are some additional subcellular
components
...
It is made
from cellulose
...
Sap is sugar and salt solution
...

Chloroplasts: Photosynthesis takes place her
...

Mitochondria: Aerobic respiration takes place here; this is where energy the is
provided from
...

Mitochondria is the source of the ATP
...

Ribosomes: This is where protein synthesis happens
...
Ribosomes are only visible by the electron microscope
...
It acts
as a barrier and holds the cells together
...

Cytoplasm: it is a gel like substance
...
It contains
enzymes that would control these reactions
...

Nucleus: This contains the genetic material (i
...
It also controls the activities of the cell
...


Bacterial Cell:
Bacterial Cells have very few similar cells content to plant or animal cell
...
They are very similar, unicellular and can only be seen through
microscope as they are around 1 nanometre in size
...
It also used to transfer
genetic material
...
It
acts as a barrier and holds the cells together
...

DNA (nucleoid): Bacteria do not have nucleus instead they have loop of floating DNA
in the cytoplasm
...
Extra
protection towards chemicals that could cause harm, also helps to stick to surfaces
...
It provides strength, rigid structure,
and support to the plant cells
...

Ribosomes: This is where protein synthesis happens
...
Ribosomes are only visible by the electron microscope
...

Cytoplasm: it is a gel like substance
...
It contains
enzymes that would control these reactions
...

Plasmids: Small rings of more DNA, can move around
...
In this
DNA antibiotic resistant genes are found
