Answer:
Brown algae are known to reproduce both sexually and asexually.
Step-by-step explanation:
In sexual reproduction, brown algae produce both eggs and sperm. The eggs are typically fertilized by the sperm of another individual, and the resulting zygote will develop into a new brown alga.
Asexual reproduction in brown algae can occur via fragmentation, in which a piece of the alga breaks off and grows into a new individual, or by means of spore formation.
