No, it isn't! Seaweed is a type of algae. Algae lack the traits used to classify plants as terrestrial: cuticle, stomata, roots, vascular tissue, or leaves Plants use cellulose with lignin in cell walls (Algae lack a cell wall or have different components like agar or alginic acids mixed with cellulose.) Algae also have little sexual reproduction and do not have a multicellular embryo like the plants have.
All algae have sperm as the motile form in their life cycle. The majority of plants have lost this trait and use pollen not sperm.

Seaweeds are not plants. They are protists. They differ from plants in that they lack vascular tissues (xylem and phloem), they have holdfasts instead of roots, and their cells do not have all of the plant characteristics.
Marine habitats are home to seaweeds, algae, sea grasses, and mangroves.
Seaweeds were once thought to be plants because according to greek thinker Aristotle, all the organisms which don't move are plants. As seaweeds don't move so they were thought to be plants. Moreover seaweeds also contain chlorophyll in them and perform photosynthesis.
Sea weeds and some water plants would conform to this description, though some would not consider seaweeds to be a plant.
