Answer 1

1. aggregate fruit

It is the fruit which is derived from multiple ovaries that are separated in a single flower or inflorescence.

example- Mulberry, bread fruit.

2.Procambium is a apical meristem

Apical meristems develop into three kinds of primary meristems- protoderm, procambium and ground meristem.

Protoderm develops into epidermis, procambium develops into xylem and phloem and ground meristem is made up of parenchyma, collenchyma and sclerenchyma.

3. Zone of maturation

Root hair develops from zone of maturation. It is the region where root differentiates into tissue of primary body. It develops from single epidermal cells.

4. Eudicot

Eudycots are embryos with two cotyledons. Pollens are with three openings. Flower parts in multiples of four or five.

5. Eudicots

Leaf venation in dicots is net or mesh like where monocots have parallel.

6..Palmate is not a type of leaf margin

crenate is with routh teeth like, lobate is indented, but not to midline whereas serrate is tooth forward pointing.

7. Secondary xylem

8. vascular.

vascular tissue is present in xylem , phloem, parenchyma and cambium cells.

9. Dermal tissue

It covers the outer surface of the plants.
