Open in App
Solution
The correct option is A Coenobium
A.Coenobium – A green alga
having fixed number of cells in it’s thallus is called Coenobium.
B.Daughter cell – Cells formed
from parent cell
C.Heterocyst - A specialized
cell found in nitrogen-fixing cyanobacteria. Heterocysts are enlarged
cells with thick cell walls and they lack chlorophyll, giving them a colourless
appearance. They are the site of nitrogen fixation, for which they produce the
enzyme nitrogenase.
D.Harmogonia - motile filaments
of cells formed by some cyanobacteria in the order Nostocales and Stigonematales.
They are formed during asexual reproduction in unicellular, filamentous
cyanobacteria, and some may contain heterocysts and akinetes.
So, the correct option is ‘Coenobium’.
