Question

Different types of meristematic tissue and ther location

Answer 1

 Meristematic tissue is like an unprogrammed computer--it is made of cells that haven't been assigned a role within the plant, or undifferentiated cells. These cells could do or be anything, just like that blank computer. Once a cell's role is assigned though (just like when the computer is programmed), its function becomes limited.

Properties of Meristematic Cells

Cells within meristematic tissues have special characteristics that make them unique when compared to cells in mature, specialized plant tissue. Cells within meristematic tissue are self-renewing, meaning that every time they divide, one new cell remains meristematic, while the second heads off to become a programmed or specialized mature cell.
Types of Meristematic Tissue

Based on its location in a plant, meristematic tissues fall into two categories: primary and secondary. Both types produce new cells through mitotic division, or the splitting of the cell in two. However, the growth pattern they produce differs. Primary meristematic tissue helps the plant increase in length or vertical growth, meaning it helps the plant grow up toward the sun and down into the soil. Secondary meristematic tissue helps the plant increase the girth or lateral growthof its stems, branches, and roots. Secondary meristematic growth is also responsible for producing the bark on woody trees

Answer 2

hey
_____

meristmatic tissue
________________

• tissues which has ability to divide

•present only at certain regions called meristems

• results in primary and secondary growth in plants

• intercellular spaces are absent

classification of meristmatic tissue on the basis of location
__________________________

• apical meristem
_______________

•peresent at growing tips of stems and roots

•cell division in this tissue leads to the elongation in the stem and roots parts

•results in primary growth

Intercalary meristem
_________________

•present behind apex

• present at base of leaf and internode region

• leads to increase in length of leaf ( primary growth)

Lateral meristem
______________

• also called secondary meristem

• occurs along sides of longitudnal axis of plant

• causes growth in girth of stem and root

• responsible for secondary growth
