Stem Cells And Meristems
- Specialised cells originate from stem cells*
- *(Cells which are yet to be specialised)
- *(Cells which are yet to be specialised)
- Stem cells can divide and produce cells that have the
potential to become more specific cell types
- Stem cells are involved in growth/development and
repair of animals
- There are two types of stem cells
- Adult stem cells
- Adult stem cells are present in tissues and organs
and can become cells such as neurons, muscle
cells or blood cells
- Adult stem cells are present in tissues and organs
and can become cells such as neurons, muscle
cells or blood cells
- Embryonic stem cells
- Embryonic stem cells can divide and
differentiate to form any type of cell in the
body
- Embryonic stem cells can divide and
differentiate to form any type of cell in the
body
- Adult stem cells
- In plants, growth occurs in special
areas called meristems
- Where mitosis occurs
- Where mitosis occurs
- Meristems are regions of actively dividing cells, which have the
potential to become almost any type of cell and contribute to growth
- There is two types of meristem
- Lateral meristems
- Lateral meristems are
found within the tens and
roots of plants
- Lateral meristems are
found within the tens and
roots of plants
- Apical meristems
- Apical meristems are found at the shoot tip
and at the root tips of plants
- Apical meristems give rise to organs
like leaves and flowers
- Apical meristems are found at the shoot tip
and at the root tips of plants
- Lateral meristems
- Mitosis in Meristems
- Embryo = Anything
- aduLt = Limited
- No particular shape or
structure
- Stem cells can not become
gametes
