Question

which alga shows a heterotrichous plant habit

Answer 1

Ans. A heterotrichous habit is the most highly evolved

type of habit in green algae. Heterotrichy means

producing two types of branches.

(a) Prostrate branches (prostrate system)

(b) Erect branches (erect system).

In some algae only the prostrate system is well

developed e.g. Coleochete scutata, in others, like

Stigeoclonium, both the systems are well

developed. Heterotrichy is dominant in

Chaetophorales.
