Procambium

QUESTION 15

Xylem and phloem elements arise from this type of tissue?

Dermal

Ground

Vascular

		Vascular cambium
		Cork cambium

Solution

1. Cork cambium. It palys a major role in secondary growth like wood (bark) in dicotyledons. Vascular cambium is responsible for Xylem and Pholem formation.

2.Animals. Edible part of fruits are eaten by animals and remaining part (seeds) dropped in other locations.

3. Winds. It has a smaller seeds with feather - like or wings it helps easily transfer in winds.

4. InDeterminate inflorescence.
Acropetal sucession - The new flowers arranged at the top and old flowers are at bottom is Racemose or Indeterminate inflorescence.

5. Determinate inflorescence
Basipetal sucession - The new flowers arranged at the bottom and old flower are at tip is cymose or determinate inflorescence.

6.Ground Tissue
It contains simple tissuse are parenchyma, collenchyma and sclerenchyma. Parenchyma cells are usually present in cortex.

7. Protoderm
It helps in develop epidermal tissues.

8. Dermal tissue
Epidermal tissue system present in outer most layer of plant system. It contains epidermal, stomato, trichomes and hairs etc.,

9. Ground meristem.
Ground meristem give rise to ground tissues and contains parenchyma, collenchyma and sclerenchyma.

10. Ground Tissues.

11. Vein
Lamina - Green expanded part of leaf. Petiole - It attach leaf and stem. Stipules- It protect leaf in bud stage.
Veins - It has channels of transport water and nutrients.

12. Apical meristem.
Apical meristem contains actively diving cells present in the root and shoot tips of the plant for elongation.

13. Lateral meristem.

14. Procambium - It leads to vascular tissues Xylem and pholem.

15. Vascular tissue.
