Some cells have cell walls (plants do, animals don't) to keep their rigid structure. They also prevent water loss.
Plants and fungi have cell walls. Note that while plants have cell walls made of cellulose, fungi cell walls are made of chitin.
Animalia
The species inside the animal kingdom are example organisms that do not have cell walls. This includes reptiles, birds and mammals.
Yes, different organisms have different substances in their cell walls. For example, plants have cell walls made of cellulose, fungi have cell walls made of chitin, and bacteria have cell walls made of peptidoglycan. These differences in cell wall composition are important for distinguishing between different types of organisms.
Bacteria with peptidoglycan cell walls and fungi with chitin cell walls are two examples of single celled organisms with cell walls.
only plants have cell walls, so all plants would be the answer.
Yes. They have a cell wall. Plants which are eukaryotes also have cell walls.
Snake
No, peptidoglycan cell walls are characteristic of Eubacteria, which are prokaryotes.
Multicellular organisms whose cells have nuclei but don't have cell walls are called anamalia cells
Various organisms have cell walls, including plants, fungi, algae and bacteria.
No, amoebas do not have cell walls made of cellulose. They belong to a group of organisms known as protozoa, which generally lack cell walls or have flexible cell membranes. Cellulose cell walls are more commonly found in plants and some algae.
