Question

Funaria
What do these plants have instead of roots?​

Answer 1

Answer:

Funaria is known as common moss or green moss. The plant body is foliose that consists of stem axis which bears many leaves and instead of roots, rhizoids are present. It is gametophytic (n) and independent. It bears antheridia and archegonia on the same plant but on different branches.

After many years of vegetative growth sex organs develop on Cycas sporophytes in the form of cones or strobili. Cycas is dioecious i.e. male cone and female cone (lax) born on separate sporophytes. The male sporophyte is heterogametic having sex chromosomes-XY while the female sporophyte is homogametic having sex chromosomes
