Question

Give the general characters of Kingdom Protista with examples.

Answer 1

Answer:

Explanation:

Examples of protists include algae, amoebas, euglena, plasmodium, and slime molds. Protists that are capable of photosynthesis include various types of algae, diatoms, dinoflagellates, and euglena. These organisms are often unicellular but can form colonies.

Answer 2

Explanation:

General characters of Kingdom Protista:

Type of organisms: The protists are unicellular and eukaryotic organisms.

Habitat: They are mostly aquatic, some are terrestrial also.

Cell wall: They are with or without cell wall. Cell wall, when present is composed of cellulose.

Membrane bound cell organelles: They contain membrane bound cell organelles such as mitochondria, chloroplasts, ER, Golgi complex, etc.

Nucleus: The nucleus is well organized, i.e. with nuclear envelope, nucleoplasm, nucleolus and linear DNA with histone proteins.

Locomotion: They are either motile or non-motile. The locomotory organs are cilia, flagella and pseudopodia.

Nutrition: They show photosynthetic, holozoic, saprophytic and parasitic mode of nutrition. They store reserve food material in the form of glycogen, starch and fat.

Reproduction: They reproduce by asexual or sexual method. Asexual reproduction occurs by budding, binary fission, etc., while sexual reproduction is without the formation of embryo. Zygote directly develops into young individual.

Types:

Protists are of different types:

a. Plant like protists (Photosynthetic protists): They are autotrophic (photosynthetic), have cellulosic cell wall and store reserve food as starch. e.g. Dinoflagellates, Diatoms.

b. Animal like protists (Consumer protists): These are heterotrophic, lack cell wall and store reserve food as glycogen. e.g. Amoeba, Paramoecium.

c.Fungi like protists (Consumer decomposer protists): They are saprophytic and lack cell wall. e.g. Slime moulds.

d. Euglenoids: Primarily, these are photosynthetic aquatic organisms, however they behave as heterotrophs in the absence of light

e.g. Euglena

Kingdom Protista is a link between prokaryotic kingdom Monera and complex eukaryotic kingdoms − Plantae, Fungi and Animalia.
