The correct option is D Statements (i), (ii) and (iii) are true
Algae are usually aquatic, either
marine or fresh water. Only a few algae occur in moist terrestrial
habitats like tree trunks, wet rocks, moist soil, etc. Plant body is
thallus (a form without any differentiation into root, stem and
leaves). Sexual, asexual and vegetative modes of reproduction are |
abundant. Form and size of algae range from microscopic unicellular
forms like Chlamydomonas, to colonial forms like Volvox
and to filamentous forms like Ulothrix and Spirogyra. So,
the correct answer is 'Statements (i), (ii) and (iii) are true'.
