Life cycle
The life cycle of most brown algae is a Haploid/Diploid life cycle, which is the most common life cycle for plants. It happens when a multi-cellular sporophyte phase rotates with a multi-cellular gametophyte phase. During the sporophyte phase, it is a large spore-producing plant, and during the gametophyte phase, there are microscopic male and female plants that produce haploid male or female cells (gametes).
