Why is seaweed in the 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.

What are seaweeds? What are their functions?
Some seaweeds are microscopic, such as the phytoplankton that live suspended in the water column and provide the base for most marine food chains. Some are enormous, like the giant kelp that grow in abundant “forests” and tower like underwater redwoods from their roots at the bottom of the sea. Most are medium-sized, come in colors ...

Is seaweed a misnomer?
The vernacular “seaweed” is a bona-fide misnomer, because a weed is a plant that spreads so profusely it can harm the habitat where it takes hold. (Consider kudzu, the infamous “mile-a-minute vine” that chokes waterways throughout the U.S. Southeast).

What is the red seaweed?
Rhodophyta or ‘red seaweeds’ are multi cellular and can come as filamentous algae, in sheets or as calcareous algae. The red seaweeds are often common at very shallow depths and even in the intertidal zone but can also be found at depth, below that of the green and brown seaweeds.
What is the role of seaweeds in the food chain?
Being able to create sugars from carbon dioxide means seaweeds provide the basis of many food chains in both marine and freshwater ecosystems and can sometimes be a significant source of food in terrestrial environments. Along with the production of food, macroalgae can also provide shelter and habitat, as plants do, ...
What are the three divisions of macroalgae?
The macroalgae are extremely diverse and have evolved in three different divisions within the algae clade; the Rhodophyta or ‘red seaweeds’, Phaeophyta or ‘brown seaweeds’ and Chlorophyta or ‘green seaweeds’ . As seaweeds are mostly photosynthetic, they play a similar role to plants in terrestrial ecosystems.
What kingdom is chlorophyta in?
Chlorophyta are believed to be the ancestor of the terrestrial plants and are classed within the Kingdom Plantae. They exhibit many similar characteristics such as using starch for food storage, cellulose cell walls and having chlorophyll a as their primary photosynthetic pigment.
What makes seaweed green?
Chlorophyll a is what makes plants green and is what absorbs light to kick off the process of photosynthesis. In water, much of light wavelengths that cholorophyll a rely on are absorbed rapidly through the water column making chlorophyll a much less efficient and making other pigments much more advantageous than they are on land. This allows for different colored seaweed to be far more common than different photosynthetic material in land plants.
What is the most complex group of macroalgae?
The ‘brown algae’ or Phaeophyta is the most complex group of macroalgae. They include the kelp species that dominate many sub-tidal zones in lower latitudes and can form dense kelp forest canopies that provide a drastically different environment than the otherwise barren rocky sub-tidal zone. The Phaeophyta also have a number of species that are able to survive permanently adrift such as Sargassum spp. in the North Atlantic Ocean which provdes shelter and habitat for many fish and invertebrate communities.
How is the abundance of seaweed determined?
The abundance of seaweed is determined by a number of biotic and abiotic factors. Light limits the lower distribution of seaweed as light availability decreases rapidly with depth, keeping the seaweed communities within a maximum depth of around 40 m.
What kingdom do algae belong to?
Molecular phylogeny (gene sequencing) and other characters show they belong to four kingdoms: Kingdom Plantae (e.g. chlorophytes and rhodophytes - green and red algae), the Kingdom Chromista (e.g.
What kingdom are plants in?
Those that belong to the Kingdom Plantae are, by defitinition, plants; the others, strictly speaking, are not. However, most people think of "plants" as organisms with roots, stems and leaves and include liverworts, mosses, ferns, flowering plants (including trees).

An alga strongly resembling the red alga Bangia (a seaweed ), Bangiomorpha pubescens, has been found in rocks 1,200 million years old. It is also the first known sexually-reproducing organism. A very similar marine organism survives to this day ( Bangia below with barnacles).
Overview
Seaweed, or macroalgae, refers to thousands of species of macroscopic, multicellular, marine algae. The term includes some types of Rhodophyta (red), Phaeophyta (brown) and Chlorophyta (green) macroalgae. Seaweed species such as kelps provide essential nursery habitat for fisheries and other marine species and thus protect food sources; other species, such as planktonic algae, play a v…
Taxonomy
"Seaweed" lacks a formal definition, but seaweed generally lives in the ocean and is visible to the naked eye. The term refers to both flowering plants submerged in the ocean, like eelgrass, as well as larger marine algae. Generally it is one of several groups of multicellular algae: red, green and brown. They lack a common multicellular ancestor, forming a polyphyletic group. In addition, blueg…
Anatomy
Seaweed's appearance resembles non-woody terrestrial plants. Its anatomy includes:
• Thallus: algal body
The stipe and blade are collectively known as the frond.
Ecology
Two environmental requirements dominate seaweed ecology. These are seawater (or at least brackish water) and light sufficient to support photosynthesis. Another common requirement is an attachment point, and therefore seaweed most commonly inhabits the littoral zone (nearshore waters) and within that zone, on rocky shores more than on sand or shingle. In additio…
Uses
Seaweed has a variety of uses, for which it is farmed or foraged.
Seaweed is consumed across the world, particularly in East Asia, e.g. Japan, China, Korea, Taiwan and Southeast Asia, e.g. Brunei, Singapore, Thailand, Burma, Cambodia, Vietnam, Indonesia, the Philippines, and Malaysia, as well as in South Africa, Belize, Peru, Chile, the Canadian Maritimes, Scandinavia, South West Engl…

Sea urchin barrens have replaced kelp forests in multiple areas. They are “almost immune to starvation”. Lifespans can exceed 50 years. When stressed by hunger, their jaws and teeth enlarge, and they form "fronts" and hunt for food collectively.
