What characteristics do algae share?

What characteristics do algae share?

Algae are eukaryotic organisms that have no roots, stems, or leaves but do have chlorophyll and other pigments for carrying out photosynthesis. Algae can be multicellular or unicellular.

What observable traits might green algae and plants share that support the molecular evidence that these two groups are related?

Some plantlike protists are multicellular also. What observable traits might green algae and plants share that support the molecular evidence that these two groups are closely related? Most protists are single celled like bacteria, but protist are eukaryotic and have membrane bound organelles.

What makes a Volvox colony different from a multicellular animal quizlet?

What makes a Volvox colony different from a multicellular animal? Volvox cells are autotrophic. Volvox cells are members of a colony.

Why are multicellular algae considered to be protists?

Algaes are difficult to define. Some classify the group as all eukaryotic photosynthesizing microorganisms. Here we have grouped algae with protozoa and slime molds in Protista because mthe majority of algae are unicellular, and even the multicellular algae are structurally simple compared to true plants. …

What are 3 characteristics of plant-like protists?

Characteristic of plant-like protists

  • Eukaryotic organism.
  • There are unicellular (form of yarn / ribbon) and some are multicellular (sheet form).
  • Has chlorophyll, so it is autotrophic.
  • Algae / algae bodies are indistinguishable from roots, stems, and leaves.

What are four examples of plant like protists?

What are the major types of protists?

Protists are typically divided into three categories, including animal-like protists, plant-like protists, and fungus-like protists. Protists vary in how they move, which can range from cilia, flagella, and pseudopodia.

What are the four main areas of protist diversity?

What are the four main areas of protist diversity? nutrition, roles, habitats, life styles3.

What 3 characteristics do protists and Animalia have in common?

They may be classified as animal-like protists (heterotrophs and have ability to move), Plant-like (autotrophs that photosynthesize) and fungi-like (heterotrophs with cells that have cell wall and reproduce by spore forming).

What are examples of animal-like protists?

Examples of Animal-like Protists

  • Amoeboid Protozoans. Amoeba are characterized by the presence of pseudopodia, or ‘false feet,’ which they use to catch bacteria and smaller protists.
  • Ciliated Protozoans.
  • Slime Molds.
  • Red Algae.
  • Brown Algae.
  • Golden-brown Algae and Diatoms.

What is the definition of a protist?

Protists are a diverse collection of organisms. While exceptions exist, they are primarily microscopic and unicellular, or made up of a single cell. The cells of protists are highly organized with a nucleus and specialized cellular machinery called organelles.

What is the common name for plant like protists?

algae

Is algae a protist?

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.

What organisms are not in Kingdom Protista?

Ascomycetes belong to the kingdom of fungi, so it does not belong to the kingdom of Protista. Protists are the eukaryotic organisms which cannot classify as the fungus, animal or plant.

Is a paramecium more like a plant or animal?

A paramecium is animal-like because it moves and searches for its own food. The have characteristics of both plant and animal. Sometimes they make food and sometimes they don’t. A spirogyra is plant-like because of the presence of chlorophyll which allows it to make its own food.

Why does paramecium never die?

Answer: Paramecium never gets old because it keeps on dividing into new paramecium by reproduction.

What is the smallest organism on earth?

Mycoplasma genitalium

What is the largest virus?

The physically largest virus is Pithovirus sibericum, at 1.5 microns (or 1,500 nanometers) in length [2]. Though that might seem tiny, it is larger than some bacteria, and approximately half the width of a strand of spider web silk [3].

What’s the smallest virus?

For the first time – scientists have detected one of the smallest known viruses, known as MS2. They can even measure its size – about 27 nanometers. For comparison’s sake, about four thousand MS2 viruses lined side-by-side are equal to the width of an average strand of human hair.
