[edit] Cells, tissues and organs

Cells act together to form tissues, for instance the cells on the surface of a leaf form "pallisade tissue". A group of cells with similar structures and a particular function is called a tissue. Tissues are grouped together to form an organ, a leaf is an organ. Organs are grouped together to form an organism such as a whole plant or animal.

Cells ----> Tissue ----> Organ ----> Organism

Tissues are usually formed from specialised cells. The cells in pallisade tissue are specialised to perform photosynthesis and contain many chloroplasts. Some other specialised cells are:

  • Guard cells
  • Egg cells
  • Sperm cells
  • Red blood cells
