What are the features of the protist cell?
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles….Characteristics of Protists
- They are eukaryotic, which means they have a nucleus.
- Most have mitochondria.
- They can be parasites.
- They all prefer aquatic or moist environments.
What is cell its structure and function?
Cells provide structure and support to the body of an organism. The cell interior is organised into different individual organelles surrounded by a separate membrane. The nucleus (major organelle) holds genetic information necessary for reproduction and cell growth. Lysosomes digest unwanted materials in the cell.
What is the cell structure 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 function of protist cells?
Protists also have mitochondria, which are the organelles responsible for turning food into energy the cell can use. Photosynthetic protist cells also have chloroplasts, or the organelles that are able to capture the energy from sunlight and turn it into sugars.
How do protists move?
A few forms can move by gliding or floating, although the vast majority move by means of “whips” or small “hairs” known as flagella or cilia, respectively. (Those organelles give their names to informal groups—flagellates and ciliates—of protists.) A lesser number of protists employ pseudopodia.
Do protists reproduce?
Reproduction. Some protists reproduce sexually using gametes, while others reproduce asexually by binary fission. Some species, for example Plasmodium falciparum, have extremely complex life cycles that involve multiple forms of the organism, some of which reproduce sexually and others asexually.
What are 3 functions of cells?
3 Major Functions of a Cell
- Energy Generation. Living cells exist in a perpetually active biological state.
- Molecular Transport. Each cell is surrounded by a membrane that delineates its boundaries and acts as a gatekeeper, controlling the movement of molecules into and out of the cell.
- Reproduction.
What is a protist cell?
A protist (/ˈproʊtəst/) is any eukaryotic organism (that is, an organism whose cells contain a cell nucleus) that is not an animal, plant, or fungus.
What do you mean by Protista?
Definition of protist : any of a diverse taxonomic group and especially a kingdom (Protista synonym Protoctista) of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that typically include the protozoans, most algae, and often some fungi (such as slime molds)
What is Kingdom Protista in biology?
Kingdom Protista Protists are a group of all the eukaryotes that are not fungi, animals, or plants. As a result, it is a very diverse group of organisms. The eukaryotes that make up this kingdom, Kingdom Protista, do not have much in common besides a relatively simple organization.
How do protists work?
Cilia – Some protists use microscopic hair called cilia to move. These tiny hairs can flap together to help the organism move through water or other liquid. Flagella – Other protists have a long tail called flagella. Pseudopodia – This is when the protist extends part of its cell body to scoot or ooze along.
