Answer 1

Explanation:

Answer 2

The difference between gametophyte of adiantum and marsilea is as follows:

Adiantum

• They have a heartshaped structure and spores are tetrahedral in shape.

• They are determinate and short-lived.

• After the formation of the cell, it gets divided into a short filament of cells. These filaments develop chlorophyll and form heart-shaped gametophyte.

Marsilea

• Marsilea is heterosporous which is generally globose.

• Female and male gametophytes are present in it.

• Both of them are endospores.

• In Marsilea, microspore produces male gametophytes and megaspores get developed into the female gametophyte.
