Cell Differentiation Stems And Meristems

Question 1

What does it mean for a cell to be differentiated

Answer 1

The process by which a cell changes to become specialised

Question 2

Where are plant stem cells found?

Answer 2

Meristems

Question 3

Why are plant stem cells useful to the plant?

Answer 3

Unspecialised cells can differentiate to form specialised cells (eg. Palisade, root hair, xylem/phloem) to perform a function; eg. photosynthesis or water + sugar transportation

Question 4

How are embryonic stem cells better than adult stem cells

Answer 4

Embryonic stem cells can differentiate into any type of cell we need. Adult some cells can only differentiate into a narrow range of cells. E.g. the stem cells in bone marrow can only differentiate into different types of blood cells.

Question 5

What is the purpose of stem cells?

Answer 5

They are able to differentiate into specialised cells to perform a specific function/need. Eg. A nerve cell for animal cells
