What kind of protist is kelp.. What kingdom is giant kelp in? Is kelp a plant? Is kelp a protist? What kingdom is a giant kelp in? These include the central medulla , the cortex with its large cells, and the meristoderm with small cells. As for reproductive cells, kelp possesses sperm and spores.

Kelp can undergo both sexual and asexual reproduction, alternating between generations in some species. Asexual reproduction entails fragments of kelp blades growing into new organisms entirely. Some cells of kelp can grow quite large, even as much as 1 centimeter across. The large cells aid in protein production and cell function.

This is important, since kelp tends to grow rapidly. Kelp does possess cell walls. The cell walls are made primarily of cellulose, just as in plants.

Each cell wall is made of a cellulose inner layer as well as an outer layer made of a substance called algin. Algin is an extracellular matrix , made of various polymers and monomers called alginates. Algin is gelatinous, meaning it can swell and is elastic, and so it is often used in the food industry as a thickener.

Despite this color, kelp does contain chlorophyll ; it is simply overlaid by a pigment called fucoxanthin. Kelp does not possess roots in the manner of plants. It uses what is called a holdfast , which is similar to a root, and attaches to whatever substrate it needs. Extending from the holdfast, its stem or stipe stretches out and possesses blades at the end. There can be more than one blade on kelp. Some of the blades have a midrib. These blades absorb sunlight for photosynthesis.

Because of this function, the blades need to be closer to the surface than other parts of the kelp. Fortunately, kelp has the perfect feature to aid in getting blades higher in the water column.

A bulbous feature resides underneath the blades, filled with gas, and that creates a flotation device for the kelp called a pneumatocyst. With this flotation the kelp blades can be held erect and therefore get greater access to sunlight. This bulb or bladder gives the kelp species "bladder wrack" its common name. Some of these bladders can extend up to 15 centimeters around. The blades of kelp age, wear and fall off over time. They are therefore annual portions of kelp, whereas the stipe or stem is perennial.

This keeps opportunistic organisms that grow on kelp from overcoming it. Kelp unfortunately exudes a nasty stench when it rots. This happens due to the generation of a sulfurous gas called methyl mercaptan.

In life cycle A left , diploid 2n zygotes result from fertilization and then undergo meiosis to produce haploid n gametes. The gametes undergo mitosis and produce many additional copies of themselves.

How are life cycles B and C different from life cycle A? QUEST explores the potential of algae-—once considered nothing more than pond scum—-to become the fuel of the future. Entrepreneurs from throughout California are working to create the next generation of biofuels from algae.

But will you ever be able to run your car off it? Many people, if not most, believe seaweed to be a plant. Is it? Plant-Like Protists: Algae Plant-like protists are called algae singular, alga. Diatoms are single-celled algae. Other forms of algae are multicellular. Ecology of Algae Algae play significant roles as producers in aquatic ecosystems. Classification of Algae Types of algae include red and green algae, and euglenids , and dinoflagellates see Table below for examples.

Type of Algae Origin of Chloroplast Type of Chloroplast Red algae cyanobacteria two membranes, chlorophyll like the majority of cyanobacteria Green algae cyanobacteria two membranes, chlorophyll like a minority of cyanobacteria Euglenids green algae three membranes, chlorophyll like green algae Dinoflagellates red algae three membranes, chlorophyll like red algae.

Reproduction of Algae Algae have varied life cycles. Summary Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed. Like plants, algae contain chlorophyll and make food by photosynthesis. Types of algae include red and green algae, euglenids, and dinoflagellates.
