About Tissues
- When a large number of identical specialised cells are found in the same place it is called a tissue.
- Sperm do not work together so semen is not counted as a tissue.
- An organ is made of many tissues working together.
- Some tissues in vertebrates that you should know:
Tissues and their Specialised Cells
A specialised muscle cell | Muscle Tissue |
A specialised xylem cell | Xylem Tissue stained orange. |
A specialised palisade cell | Palisade Tissue is the layer of rectangular cells near the top of the leaf, just under the top layer. |
