Meristematic tissue• Meristematic tissue is

composed of immature cells that grow, divide & differentiate giving rise to the other types of plant tissues.

• Eg. The root tip of an onion

Surface of a leaf• Note the guard cells.

What tissue type has this feature?

Xylem• Long tubes• Note the pits • Transport of water,

dissolved solutes.• Support

What do we call these features?

Vascular bundles (cross section)

Phloem –• Long tubes composed

of sieve tubes and companion cells.

• Transport of sugar.Xylem

Parenchyma

What are these?

What are those ringlets?• Parenchyma is a

simple tissue. It makes up the bulk of plant body.
