Cell wall
The cell wall is a tough
rubbery wall that protects
the inner organs but
sometimes fairly rigid layer
that surrounds some types
of cells. It is located outside
the cell membrane and
structural support and
protection, in addition to
acting as a filtering
mechanism
Golgi
complex
Part 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.
Ribosome
s
Ribosomes are cell
organelles that consist of
RNA and proteins. They
are responsible for
assembling the proteins of
the cell. Depending on the
protein production level of
a particular cell, ribosomes
may number in the
Nucleus
The nucleus is the cell brain it
contains the cell uniqueness and tells
the cell what to do.
Mitochondria
Mitochondria are known as the powerhouses of
the cell. They are organelles that act like a
digestive system which takes in nutrients, breaks
them down, and creates energy rich molecules for
the cell. The biochemical processes of the cell are
known as cellular respiration. Many of the
reactions involved in cellular respiration happen
in the mitochondria. Mitochondria are the
working organelles that keep the cell full of
energy.
cytoplasm
Cytoplasm is the fluid that fills a cell.
Scientists used to call the fluid protoplasm.
Early on, they didn't know about the many
different types of fluids in the cell. There is
special fluid in the mitochondria,
endoplasmic reticulum, Golgi apparatus,
and nucleus. The only two 'plasms' left are
cytoplasm (the fluid in the cell also called
cytosol) and nucleoplasm (the fluid in the
nucleus). Each of those fluids has a very
different composition
vacuole
A vacuole is a membranebound organelle which is
present in all plant and
fungal cells and some
protest, animal and
bacterial cells.
chloroplast
Chloroplasts are the food producers of the cell. The organelles
are only found in plant cells and some protests such as algae.
Animal cells do not have chloroplasts. Chloroplasts work to
convert light energy of the Sun into sugars that can be used by
cells. The entire process is called photosynthesis and it all
depends on the little green chlorophyll molecules in each
chloroplast.
Plants are the basis of all life on Earth. They are classified as the
producers of the world. In the process of photosynthesis, plants
create sugars and release oxygen (O2). The oxygen released by
the chloroplasts is the same oxygen you breathe every day.
Mitochondria work in the opposite direction. They use oxygen in
the process of releasing chemical energy from sugars.
Cell membrane
According to cell theory, cells are the main unit of
organization in biology. Whether you are a single cell or
a blue whale with trillions of cells, you are still made of
cells. All cells are contained by a cell membrane that
keeps the pieces inside. When you think about a
membrane, imagine it is like a big plastic bag with some
tiny holes. That bag holds all of the cell pieces and fluids
inside the cell and keeps any nasty things outside the
cell. The holes are there to let some things move in and
