What is the algae of Kingdom Protista?
What is the algae of Kingdom Protista?
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista. Algae have many types of life cycles, and they range in size from microscopic Micromonas species to giant kelps that reach 60 metres (200 feet) in length.
Why algae is known as plant-like protists?
Plant-like protists, also called algae are a large and diverse group of simple plant-like organisms. They are considered “plant-like” because they photosynthesize, and are considered “simple” because they do not have the distinct organization of higher plants such as leaves and vascular tissue.
What is a plant-like protist?
Most plant-like protists are single celled but some live in colonies or are multicellular making up red, brown (kelp/seaweed), and green algae. Plant-like protists are responsible for producing most of earth’s oxygen. Other examples include diatoms and euglena.
Why are protists classified as being plant-like animal-like or fungus-like?
Protists are called plant-like, fungus-like and animal-like because they share some of the characteristics of plants, fungi and animals, even though they belong in a different category: the kingdom Protista.
What are fungi like protists?
What are fungus-like protists? They are protists that absorb their food from dead organic matter. They are grouped into 2 groups, slime molds and water molds. Most fungus-like protists use psuepods, (“false feet”) to move around.
Is algae a protist or plant?
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.
What are fungus-like protists called?
Fungus-like protists are molds. Molds are absorptive feeders, found on decaying organic matter. They resemble fungi and reproduce with spores as fungi do. Examples of fungus-like protists include slime molds and water molds.
Why are algae not in the plant kingdom?
The main reason is that they contain chloroplasts and produce food through photosynthesis. However, they lack many other structures of true plants. For example, algae do not have roots, stems, or leaves. Some algae also differ from plants in being motile.
Is algae a kingdom?
In the 5-kingdom scheme of classification, the algae, together with the protozoa, belong to Kingdom Protista. The Cyanophyta or blue-green algae, which are prokaryotic organisms, are traditionally included in this group but in modern classification, they are now grouped together with bacteria under Kingdom Monera.
How are animal-like protists different than algae?
Animal-like protists are called protozoa. Most consist of a single cell. Plant-like protists are called algae. They include single-celled diatoms and multicellular seaweed.
What features of algae are plantlike?
Algae are considered simple, plant-like organisms. They are “plant-like” because they photosynthesize and “simple” because they do not have the distinct organization of higher plants such as organs and vascular tissue.
