How are the algae separated or distinguished from each other?

How are the algae separated or distinguished from each other?

Algae lack tissue differentiation and have no true roots, stems, and leaves. The gametangia of algae are single-celled; the gametangia of plants are multicelled. Why is phytoplankton important to other organisms?

How are algae subdivided into divisions?

The algae are subdivided into several divisions (rather than phyla, like the protozoa): Rhodophyta, Pyrrophyta, Chrysophyta, Phaeophyta, and Chlorophyta. The divisions are based in part on the types of pigments and colors they have.

How do we classify algae?

There is three main Algae classification:

1. Chlorophyceae – These are called green algae, due to the presence of pigments chlorophyll a and b.
2. Phaeophyceae – Also called as brown algae, they are predominantly marine.
3. Rhodophyceae – They are the red algae because of the presence of the red pigment, r-phycoerythrin.

What characteristics separate algae from protozoans and plants?

#1 What characteristics separate algae from (a) protozoans and (b) plants? The characteristics that separate algae from protozoan are planktons. The chacteristics in plants is it is a type of plant. 2 types of asexual reproduction in algae are Chlamydomonas and zoospores.

Are algae single celled?

Algae are morphologically simple, chlorophyll-containing organisms that range from microscopic and unicellular (single-celled) to very large and multicellular. The algal body is relatively undifferentiated and there are no true roots or leaves.

What are the three groups of algae that are divided into phyla?

The three main taxonomic groups of macroalgae: (a) phylum Chlorophyta—green algae; (b) phylum Rhodophyta—red algae; (c) phylum Ochrophyta, class Phaeophyceae—brown algae. Table 1. Classification and pigment composition characteristic of some algae [1].

What phylum does algae belong to?

Phaeophyta: phylum of the kingdom protista consisting of those organisms commonly called brown algae. Many of the world’s familiar seaweeds are members of phaeophyta. Like the chrysophytes brown algae derive their color from the presence, in the cell chloroplasts, of several brownish carotenoid pigments, as fucoxathin.

What are the other unicellular algae?

Chlorophyta (green algae), mostly unicellular algae found in fresh water. The chlorophyta are of particular importance because they are believed to be most closely related to the evolution of land plants. Diatoms, unicellular algae that have siliceous cell walls.

Is algae a phylum?

Phaeophyta: phylum of the kingdom protista consisting of those organisms commonly called brown algae. Many of the world’s familiar seaweeds are members of phaeophyta.

Do algae have vascular tissue?

No algae does not have and does not require vascular tissue, because whole body or entire cell of the body is in contact with/submerged in the water hence they do not require vascular tissue.

What characteristics are used to put algae into their phyla?

Within the classification of algae, individual species are divided into five groups, based on characteristics such as type of chlorophyll molecule used in photosynthesis and type of reproductive cycle. The structure of the chloroplast is also used, for a very important reason.

What differentiates algae from plants and two ways they are different from protozoans?

The major difference between algae and protozoa is that algae are able to make their own food, as plants do, while protozoa ingest other organisms or organic molecules, as animals do.

What is the phyla of algae?

Phyla of Algae. Algae are a diverse group of simple organisms that live in aquatic environments, including the ocean, freshwater, ponds and moist land. Algae contain chlorophyll and are able to go through the process of photosynthesis, like plants; however, they lack the organs and kinds of cells found in plants.

What is the most common type of single celled algae?

Chrysophyta (Golden-brown algae and Diatoms) are the most abundant types of single-celled algae (approximately 100,000 different species). Pyrrophyta (Fire algae) are single-celled algae. They are found in both the oceans and in fresh water. They use flagella to move around.

What is the difference between paeophyta and red algae?

Rhodophyta (Red algae) are mostly found in tropical marine environments. These eukaryotic cells do not have flagella and centrioles, unlike other types of algae. Paeophyta (Brown algae) are among the largest species. Examples include both seaweed and kelp.

How many flagella does an algae have?

They possess one, two, four, or eight flagella, with or without cell walls, scales, thecae, or loricae. They are mostly motile and photosynthetic algae containing pigments like chlorophyll a, and chlorophyll b. They are mainly marine algae, but some are also found in brackish- and freshwater habitats.
