Is seaweed Plantae or Protista?
algae
Many people, if not most, believe seaweed to be a plant. Is it? Seaweed is actually a plant-like protist, which are also known as algae.
Is seaweed in Kingdom Protista?
Algae are part of the ‘Kingdom Protista’, which means that they are neither plants nor animals. Seaweeds are not true plants because they lack a vascular system (an internal transport system for fluids and nutrients), roots, stems, leaves, and enclosed reproductive structures like flowers.
Is seaweed in Plantae Kingdom?
Seaweeds are not a single taxnomic entity. Molecular phylogeny (gene sequencing) and other characters show they belong to three kingdoms: Kingdom Plantae (chlorophytes and rhodophytes), the Kingdom Chromista (phaeophytes), and the Kingdom Bacteria (cyanophytes).
What group is seaweed belong in?

| Seaweeds can be found in the following groups | |
| Chlorophyta (green algae) Phaeophyceae (brown algae) Phaeothamniophyceae Chrysophyceae (gold algae) Cyanobacteria Rhodophyta (red algae) |
Why are seaweeds assigned to the Protista rather than Plantae Kingdom?
Why are seaweeds assigned to the Protista rather than Plantae? Seaweed has many plantlike features but it is not a plant, it is algae. Algae is assigned to Protista causing seaweed to fall under Protista as well. The stipe also supports the rest of the plant.
Is Plantae prokaryotic or eukaryotic?
Kingdom Plantae consists of organisms that are eukaryotic.
Are protists photosynthetic?
According to Simpson, protists can be photosynthetic or heterotrophs (organisms that seek outside sources of food in the form of organic material). In turn, heterotrophic protists fall into two categories: phagotrophs and osmotrophs.
How is seaweed a protist and not a plant?
Unlike plants, however, plant-like protists do not have true stems, roots, or leaves. Protists can be unicellular (single-celled) or multicellular (many-celled). Seaweed and kelp are examples of multicellular, plant-like protists. Kelp can be as large as trees and form a “forest” in the ocean (Figure below).
What characteristics are seaweeds classified?
Seaweeds do not have roots, stems, or leaves, or flowers. They have holdfasts, stipes, and blades, and sometimes floats. Seaweeds have different structures than land plants because they live in the water rather than on land.
