Plants are the ancestors of seaweeds. Convergent evolution caused their similarity. Both evolved from brown algae. Seaweeds are the ancestors of plants. Seaweeds are aquatic plants.
Seaweeds are not plants it is a type of algae
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.
Fungi and plants are multicellular.
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.

Perhaps the large seaweeds (algae), but maybe the Banana if you're seeking terrestrial plants.
You know, I was wondering the same thing! Except in my school project, I need to know seaweeds abiotic needs. Any suggestions? 2. Algae were the first plants to use photosynthesis, which has proved to be a hit. The Latin word for seaweed was algae. seaweeds come in red, brown and green. It is thought that the green seaweeds are the origin of all plants. Seaweeds need water and a small amount of nutrients, and sunlight. they are VERY fast growing in the right conditions.
