Cell Membrane- Controls
the passage of substances
in and out of the cell.
Nucleus- Which contains
the genetic material and
controls the activities of
the cell.
Cytoplasm- In which most
of the chemical reactions
take place.
Mitochondria- To release
energy in respiration.
Ribosome- To produce
Cell wall-For support proteins (protiensynthesis)
Vacuole- Contains cell
sap, also for support
nucleus Plant mitochondria
Chloroplasts- Contains
chlorophyll for
As organisms reticulum
develop, some of
their cells become cytoplasm chloroplast
specialised to
carry out
particular jobs.
This is called membrane
vacuole cell wall…read more

Molecules move randomly because of the
energy they have. Diffusion is the
movement of molecules from an area of
high concentration to an area of low
concentration (net movement). Example:
the diffusion of oxygen into the cells of
the body from the blood stream as the
cells are respiring (and using up oxygen).
This is a special type of diffusion that
only occurs with water. It's molecules also
move randomly requiring no energy form
the cell. Osmosis can only occur across a
partially permeable membrane from a
dilute solution to a more concentrated
solution.…read more
