Question

How is algae a protist?

Answer 1

Hint: Algae, singular alga, are a category of primarily watery photosynthetic animals that belong to the kingdom Protista. Algae come in a variety of sizes and life cycles, ranging from microscopic Micromonas species to gigantic lengths. Their photosynthetic pigments are more diverse than plants', and their cells have characteristics not found in either plants or animals.
Algae are commercially essential as a source of crude oil, food, and a variety of pharmaceutical and industrial products for humans, in addition to their ecological responsibilities as oxygen providers and the nutritional base for practically all aquatic life.
Phycology is the study of algae, and a psychologist is someone who studies algae.

Complete answer:
Algae are mostly photosynthetic and aquatic organisms that do not belong to the plant or animal kingdoms. Plant-like protists, on the other hand, range in size from minuscule unicellular diatoms to giant multicellular seaweed.
Algae are classified under the Kingdom Protista because they are eukaryotic, unicellular organisms with the Kingdom Protista trait.
All single-celled eukaryotes are classified as Protista. The kingdom's borders, on the other hand, are not firmly defined. Protista is largely an aquatic phylum. This kingdom is linked to the kingdoms of plants, animals, and fungus. Like other eukaryotes, the protist cell body has a well-defined nucleus and other membrane-bound organelles.
Some have flagella or cilia, while others don't. Cell fusion and zygote development are used by protists to reproduce both asexually and sexually. It's possible that it's photosynthetic or holotropic. Saprotrophic, parasitic, and symbionts are all possibilities.

Note:
The zygote is in the form of a two-nucleotide repeat. Meiosis is the most common way for it to divide (also called zygotic meiosis). These give rise to 1n chromosome-containing vegetative cells. Mitosis is a cell division process that occurs regularly in these cells. The number of chromosomes in the daughter cells is maintained at 1n. Gametes are produced by some vegetative cells. When these gametes fertilise each other, a zygote is formed, and the life cycle gets completed.
