Cells that have changed their shape and structure to carry out a particular job
Organelles found only in plant cells
Cell wall
Vacuole
Chloroplast
Mitochondria
Organelle that carries out respiration/produces energy for the cell
Nucleus
Organelle that contains genetic material and controls the cell
What are specialised cells?
A specialised cell is a cell that has changed its shape and structure so it can carry out a particular job
Nerve cells
They are really long and have connections at both ends, so they can transmit messages around the body by sending electrical signals to each other
Red blood cells
They do not have a nucleus, but they do have haemoglobin and their biconcave shape allows them to carry a lot of oxygen around the body
Sperm cells
They have a streamlined shape and a long tail so they can swim through liquid, and they have a lot of mitochondria to provide energy

Leaf (palisade) cells
Plant cells that contain chloroplasts
Root hair cells
Plant cells that do not contain chloroplasts
Leaf (palisade) cells
Contain chloroplasts
Root hair cells
Do not contain chloroplasts
Job vacancies for specialised cells
Energetic cell for delivery of genetic material. Must be very fast and well-suited for movement through liquid (Sperm cell)
Transmit messages around the body by sending electrical signals to each other (Nerve cell)
Carry a lot of oxygen around the body (Red blood cell)
Carry out photosynthesis (Leaf cell)
Absorb water and nutrients from the soil (Root hair cell)
