2. contains simple and bordered pits

3. smallest  cells in plant body

4. All of these

Mechanical support to the growing parts of the plant such as young stem and petiole of leaf is provided by a living tissue called

Which of the following function can be performed by
both parenchyma and collenchyma?
1. Storage.

3. Sclerenchyma

4. Parenchyma

Choose odd with respect to collenchyma

1. Living mechanical tissue

2. Intercellular space is absent in angular type

3. Thickening of the wall is due to deposition of lignin
