What type of cell wall does paramecium have?
Paramecium wears a soft armor, called pellicle The body of the paramecium cell is enclosed by a stiff but elastic membrane, called pellicle. Pellicle is made up of a thin, gelatinous substance produced by the cell. The layer of the pellicle gives the paramecium a definite shape and good protection of its cell content.
Plant cell walls are primarily made of cellulose, which is the most abundant macromolecule on Earth.

Do paramecium have mitochondria?
Paramecium cells are mitochondria-rich: Each individual cell in P. aurelia species is estimated to contain about 5,000 mitochondria, with about 8″10 genomes per mitochondrion (Beale and Tait 1981), which is much larger than in mammalian cells with 1,000″2,000 mitochondria (Kukat et al.
Which is absent in archaebacteria?
Cell walls: virtually all bacteria contain peptidoglycan in their cell walls; however, archaea and eukaryotes lack peptidoglycan. Various types of cell walls exist in the archaea. Therefore, the absence or presence of peptidoglycan is a distinguishing feature between the archaea and bacteria.
Do fungi have a cell wall?
The cell wall is a characteristic structure of fungi and is composed mainly of glucans, chitin and glycoproteins.
What cell does not have a cell wall or chloroplasts?
Monera (includes Eubacteria and Archeobacteria) Individuals are single-celled, may or may not move, have a cell wall, have no chloroplasts or other organelles, and have no nucleus. Monera are usually very tiny, although one type, namely the blue-green bacteria, look like algae.
What is cellulose in a cell wall?
Cellulose, a tough, fibrous, and water-insoluble polysaccharide, plays an integral role in keeping the structure of plant cell walls stable. Cellulose chains are arranged in microfibrils or bundles of polysaccharide that are arranged in fibrils (bundles of microfibrils), which in turn make up the plant cell wall.
What type of cells have chloroplasts?
Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant.
What is an example of a cell wall?
An example of a cell wall is the rigid cellulose outside the cell membrane of a plant. (cytology) A thick, fairly rigid, layer formed around individual cells of bacteria, Archaea, fungi, plants, and algae (but not animals and other protists which generally have cell membranes without cell walls).
Do all cell membranes have a cell wall?
All cells have a cell membrane, although there are slight variations. Some cells also have cell walls. While these cell walls provide additional protection and support, they do not replace the function of the cell membrane.
What kind of prokaryotes have cell walls?
Gram-Positive and Gram-Negative Bacteria While all bacteria have a cell wall, its composition changes from species to species owing to differences in the peptidoglycan content of which the cell walls are partly or mostly made.
What are prokaryotic cell walls made of?
Prokaryotic cell walls may be composed of peptidoglycan (bacteria) or pseudopeptidoglycan (archaea). Gram-positive bacterial cells are characterized by a thick peptidoglycan layer, whereas gram-negative bacterial cells are characterized by a thin peptidoglycan layer surrounded by an outer membrane.

What is called cellulose?
Cellulose is a molecule, consisting of hundreds ” and sometimes even thousands ” of carbon, hydrogen and oxygen atoms. Cellulose is the main substance in the walls of plant cells, helping plants to remain stiff and upright. Humans cannot digest cellulose, but it is important in the diet as fibre.
Why is cellulose suitable for cell walls?
Cellulose provides rigidity to the plant cells. The high tensile strength of cellulose fibers present in the plant cell wall is responsible for maintaining the shape and rigidity of plant cells.
