SB2c growth in plants

Question 1

describe the stages of growth in plants

Answer 1

cell division/mitosis, elongation, differntiation

Question 2

definition of cell differntiation, elongation, and cell division

Answer 2

cell differentiation - process which cell changes to become specialized for its job ( divides by mitosis to produce 2 different types of cell
cell elongation - plant cell expands - cell bigger - plant grow

Question 3

examples of specialized plant cells

Answer 3

root hair cells, palisade cells, xylem cells and phloem cells.

Question 4

describe how the structure of specialized plant cells are related to their functions

Answer 4

A long thin ‘hair’ extends from each cell into the soil increasing the root’s surface area.

Question 5

explain why cell differntiation is important in the development of specialized cells in plants

Answer 5

growth in height is mainly due to cell elongation - cell division usually just happens in the tips of the roots and shoots ( areas called meristems ) plants often continue to grow, plant continue to differntiate to develop new parts
