Answer:
Option D, structure of sperm cells, presence of phragmoplasts, and rings of cellulose-synthesizing complexes
Explanation:
The cells of Charophyte contain several chloroplast and nuclei and thus they are known as coenocytic.
The structure of their sperm is very similar to that of the plants on land which make it distinctive from other fresh water algae. The sperm has flagella that makes it motile.
Only one of the Charophyta species uses the phragmoplast method of cell division just like plants
Like land plants, charophytes' plasma membrane has distinctive rings of cellulose-synthesizing complexes which synthesizes cellulose microfibrils
Hence, option D is correct
