Root Hair Cell
Organelles
Function
Nucleus
An organelle which contains the genetic material
that controls the cell’s activities. It is surrounded
by its own membrane.
Cytoplasm
A gel-like substance where most of the cell’s
chemical reactions happen. It contains enzymes
which control these reactions.
Cell Wall
A rigid structure made of cellulose, which
surrounds the cell membrane. It supports the cell
and strengthens it.
Vacuole
A large organelle that contains cell sap (a weak
solution of sugars and salts). It helps support the
cell.
Cell Membrane
This membrane forms the outer surface of the
cell and controls the substances that go in and
out.
Ribosomes
Small organelles where proteins are made in a
cell.
Mitochondrion
Small organelles were most of the reactions of
aerobic respiration take place. Respiration
transfers energy that the cell need to work.
Root hair cells are adapted for taking up water and mineral ions by having a large surface
area to increase the rate of absorption. They also contain lots of mitochondria , which release
energy from glucose during respiration in order to provide the energy needed for active
transport. (BBC Bitesize)
