Plant tissues

What is a plant tissue?

A group of one or more cell types which carries specialized functions.

What are meristems?

Undifferentiated tissues in plants with cells which constantly divide under suitable conditions to produce new cells.

What are the activities shown by meristematic cells?

Meristematic cells can elongate and differentiate, producing new tissues of the plant body, while some remain as meristems.

How do plants grow?

Plant growth occurs by making new tissues through the action of meristematic cells, which divide and differentiate.

What are the characteristics of meristematic cells?

1. Structural: Isodiametric shape and a central nucleus with dense cytoplasm. 2. Functional: All are living cells, with the ability to multiply, and are structurally and functionally undifferentiated.

What are the characteristics of meristematic cells?

1. Structural: Isodiametric shape and a central nucleus with dense cytoplasm. 2. Functional: All are living cells, with the ability to multiply, and are structurally and functionally undifferentiated.

Name three overlapping zones in meristems.

1. Zone of cell division 2. Zone of cell elongation 3. Zone of cell differentiation

How are plant tissue systems formed?

Plant tissue systems are formed from new cells originating from meristems, which then differentiate to perform specialized functions.

Which parts of the plant cells undergo changes during differentiation?

During differentiation, the cytoplasm, organelles, and cell wall undergo changes.

What are the three main tissue systems in vascular plants?

1. Dermal tissue
2. Ground tissue
3. Vascular tissue
