๐ฌ Think about it
A tiny seedling becomes a tall tree, roots dig deep, stems thicken, and grass grows back after being cut. Something inside the plant keeps making new cells. Which tissue does this? Let us find out.
In what ways do plants grow?
- They increase in length (taller stems, deeper roots).
- They increase in girth (thicker stems).
- They regrow after branches are cut or grazed.
Three Ways Plants Grow
Plant growth
↓
In length
Taller stems and deeper roots.
In girth
Thicker stems.
Regrowth
New growth after cutting or grazing.
Which tissue is responsible for plant growth?
- Growth needs actively dividing cells.
- These cells together form a meristematic tissue.
- There are different kinds of meristematic tissue.
Example:
The growing tip of an onion root is full of dividing meristematic cells.
