The nucleus is the control centre in the cell.
It controls all that happens inside, the Nucleus
contains chromosomes which carry long
threads of DNA Which contain genetic code to
pass onto one generation to another and
make new cells.. It controls all the chemical
processes that happen in the cell
Cytoplasm
The cytoplasm is the jelly-like substance in
the living cell. One of its major elements are
the organelles it has (excluding the nucleus)
like the mitochondrion, where most
respiration occurs and other chemical
reactions to keep the cell alive. These
reactions are controlled by enzymes.
Cell membrane
The cell membrane is the selectively permeable
(allowing gases and liquids to pass through;
penetrable) membrane or barrier, which controls
which substances can enter and exit the cell. It also
gives it its shape
Mitochondria
The mitochondria is a structure in the
cytoplasm where most aerobic respiration
happens and glucose is turned into energy
and oxygen is used
Nucleus
Cytoplasm
Cell membrane
Mitochondria
Chloroplast
The chloroplast contains a green
pigment called chlorophyll . It absorbs
sunlight in the process of
photosynthesis
Vacuole
The long lasting vacuole or space is within
the cytoplasm containing salts and sugars
called cell sap. This keeps the cell firm and
gives it support.
Cell wall
The cell wall is the outer protective layer made of cellulose of a
cell which covers the thin membrane. It is also a strong
container which prevents the outburst of water from the uptake
of it by osmosis. different organs have dissimilar structures and
chemical compositions, like of a plant, fungal or bacterial
organism.
Multicelluar
A multicelluiar organism is a living thing
with lots of cells. Thc cells in a multicelluar
animal or plant are specialised or
differnated to carry out a specific funcion.
For example the task of a red blood cell is
to carry oxygen around the body. It is
speacialised because it has a large surface
area to let oxygen pass through, it has no
nucleus to let more heamaglobin inside it
to join onto the oxygen
Red blood cell
Nerve cell
Sperm cell
Advantages: They
are larger because
they have more
cells
Disadvantages:
they need more
energy to function
Unicelluar
A unicelluar organism is a living thing with just
one cell. They may be one but they are quite
complex. They have special features that make them
suited for their environment. For example bacterial
cells which is a domain of Prokaryotic cells, has a
flagellum which helps it move around like a
propellor
Bacteria
To reproduce
they split into
two and so on
Yeast
A unicelluar organism
that is added to bread
to make it rise
Protoza
Amobea is a
type of protoza
which behaves
like an animal
Advantages:
they reproduce
quicker because
it doesn't have to
find a mate, it
does it by itself
Disadvantages:
They have a
short life span if
their one cell
gets damaged it
results in death.
It has to do all
its life processes
by itself so it
takes longer
