Which of the following is a reason why green algae is considered to be protists rather than plants?
Terms in this set (99) List the reasons why the algae are no longer classified as plants. They don't have vascular tissue, lack true rots, leaves, and stems, they form single-celled gametes (Gametangia), where true plants produce gametes in multicellular gametangia.
Is green algae a plant or protist?
Plant-like protists are called algae (singular, alga). They are a large and diverse group. Some algae, the diatoms, are single-celled….Classification of Algae.
| Type of Algae | Origin of Chloroplast | Type of Chloroplast |
|---|---|---|
| Green algae | cyanobacteria | two membranes, chlorophyll like a minority of cyanobacteria |

Why is green algae not a plant?
The "green algae" is a paraphyletic group because it excludes the Plantae. Like the plants, the green algae contain two forms of chlorophyll, which they use to capture light energy to fuel the manufacture of sugars, but unlike plants they are primarily aquatic.
Did kingdom Plantae arise from green algae?
Algal ancestors of land plants. The land plants arose from the green algae, and, together, land plants and green algae are sometimes called "Viridiplantae" (from the Latin viridis = green).
Why is green algae related to plants?
Green algae contain the same carotenoids and chlorophyll a and b as land plants, whereas other algae have different accessory pigments and types of chlorophyll molecules in addition to chlorophyll a. Both green algae and land plants also store carbohydrates as starch.
What makes green algae different from plants?
The main difference between algae and plants lie in their cellular composition. While algae can exist as both unicellular and multicellular structures, plants are only multicellular.
Why are green algae considered protists?
All algae are eukaryotic organisms. All algae, therefore, have a nucleus enclosed within a membrane and chloroplasts bound in one or more membranes. Example of plantlike protists, from very large kelp (left), to the microscopic marine dinoflagellate Karenia brevis (right).
Why is algae considered protists?
Protists are eukaryotes as they possess a nucleus and other membrane-bound organelles (structures that perform a specific job). At one time, simple organisms such as amoebas and single-celled algae were classified together in a single taxonomic category: the kingdom Protista.
Why are algae not included in kingdom Plantae?
Algae are not included in the kingdom Plantae because algae lack the structures needed for true plants to grow, such as stomata, a part of a plant…
What kingdom does green algae belong to?
PlantArchaepla… Green algae/Kingdom
Why is algae not classified in kingdom Plantae?
Algae are not included in the kingdom Plantae because algae lack the structures needed for true plants to grow, such as stomata, a part of a plant…
Why is algae a protist?
Algae are called living organisms. They possess chlorophyll that helps in photosynthesis. They are considered plant-like protists. They are simple organisms that lack complex plant organs such as roots, stems, and leaves.
Why are algae not included in the kingdom Plantae?
Algae are not included in the kingdom Plantae because algae lack the structures needed for true plants to grow, such as stomata, a part of a plant…
Why protists are placed in separate kingdom?
The kingdom Animalia includes all multicellular, eukaryotic, heterotrophic organisms whereas, the kingdom Protista includes all unicellular, eukaryotic and heterotrophic organisms. Hence, Protozoans are placed under the kingdom Protista instead of the kingdom Animalia.
Is algae in 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 are blue-green algae included under Kingdom Monera and not under kingdom Plantae?
The DNA is naked meaning it is not enclosed within nuclear membrane. Their genetic material is dispersed loosely in the cell. Whereas, the genetic material of plants is present in the cell nucleus. Hence, blue green algae are included under Kingdom Monera and not under Kingdom Plantae.
Is algae considered a protist?
Many diverse organisms including algae, amoebas, ciliates (such as paramecium) fit the general moniker of protist.
Is algae in the kingdom Protista?
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.
Does algae belong to Protista?
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.
Why is Protista not a true kingdom?
Kingdom Protista is not considered a true kingdom because, this kingdom comprises many organisms, which are related to the kingdoms of fungi, plants and animals.
Why are protists plants fungi and animals classified into the same domain but different kingdoms?
Why are protists, plants, fungi, and animals classifies into the same domain but into different kingdoms? They are the same domain because they are all Eukaryotes. However they are different from each other.
Why are protists in their own kingdom?
Protists have their own kingdom because they cannot be logically classified with the other single-celled organisms, the archaea.
What kingdom is blue-green algae in?
BacteriaCyanobacteria / Kingdom Algae have since been reclassified as protists, and the prokaryotic nature of the blue-green algae has caused them to be classified with bacteria in the prokaryotic kingdom Monera.
Why are bacteria and blue-green algae not considered true cells?
Bacteria are prokaryotic organisms that are not considered as true cells because of the following reasons: 1) Bacteria do not have a true nucleus. The DNA in bacteria rather is arranged in single circular strand in its cytoplasm. 2)the organelles in the blue algae also lack membrane unlike other cells.
Why is algae classified in the protist kingdom?
Protists are eukaryotes as they possess a nucleus and other membrane-bound organelles (structures that perform a specific job). At one time, simple organisms such as amoebas and single-celled algae were classified together in a single taxonomic category: the kingdom Protista.
Which algae is present in kingdom Protista?
The protists are a diverse group of eukaryotes that cannot be classified as animals, plants, or fungi. Organisms in the Protista kingdom include amoebae, red algae, dinoflagellates, diatoms, euglena, and slime molds.
Why are protists placed in their own kingdom?
Protists have their own kingdom because they cannot be logically classified with the other single-celled organisms, the archaea.
Why is Protista not a kingdom anymore?
Kingdom Protista is not considered a true kingdom because, this kingdom comprises many organisms, which are related to the kingdoms of fungi, plants and animals.
Which algae is placed in Protista kingdom?
Blue green algae Blue green algae belongs to the kingdom Protista.
Where is algae placed in which kingdom?
algae, singular alga, members of a group of predominantly aquatic photosynthetic organisms of the kingdom Protista.
