Question

describe the structure of ulva​

Answer 1

Each cell contains one nucleus and has a cup-shaped choroplast with a single pyrenoid. Ulva undergoes a very definite alternation of generations. Biflagellate isogametes are formed by certain cells of the haploid, gametangial plant

Answer 2

here you go

This is a small genus of marine and brackish water green algae. It is edible and is often called 'Sea Lettuce'. Species with hollow, one-layered thalli were formerly included in Enteromorpha, but it is widely accepted now that such species should be included in Ulva.

The thallus of ulvoid species is flat and blade-like and is composed of two layers of cells. There is no differentiation into tissues; all the cells of the plant are more or less alike except for the basal cells, which are elongated to form attachment rhizoids. Each cell contains one nucleus and has a cup-shaped choroplast with a single pyrenoid.
