growth and differentiation Flashcards
why are the cells in your body not all the same
the cells in your body are not all the same because as cells divide, grow and develop, they also begin to differentiate
what’s differentiate
differentiate is the process where cells become specialised for a particular function
what is a stem cell
a stem cell is an undifferentiated cell with the potential to form a wide variety of different cell types
what are the differences between differentiation in animal and plant cells
Animals: Most cells differentiate very early in life, usually before birth.
Plants: Cells can differentiate throughout their entire lives.
Cell division mainly occurs for repair and replacement in mature animals, with little or no growth.
Plants: Mitosis occurs continuously in specific growing regions (meristems), leading to ongoing growth.
Animal: Once a cell differentiates (e.g., muscle or nerve cell), it cannot change into another type of cell.
Plants: Differentiation is not permanent; cells can re-differentiate if moved to another location.
Animal :Cells are usually specialised by the time of birth and function in specific roles.
Plants: Cells differentiate only after reaching their final position in the plant.
what is cloning
cloning is the production of identical offspring by asexual reproduction
why is it difficult to clone animals
it is difficult to clone animals because most animal cells differentiate permanently early in embryo development and the cells cannot change back
