Which of the following is correct about bryophytes?
1 They have rhizoids
2 They contain antheridium
3 They possess archegonia
4 All of the above
Explanation:
Sex organs is bryophytes are antheridium (male) and archegonium (female). Bryophytes have root-like structures called rhizoids which help in attachment of thallus to substratum. These rhizoids can be unicellular or multicellular.
