Cell wall: We know that not all living organisms have cell walls around their cells e.g. animals and many animal-like protists. Cell wall is a non-living and strong component located outside the plasma membrane. It provides shape, strength, protection and support to the inner living matter (protoplasm) of cells.
Understand the Problem
The question is a statement describing the characteristics and functions of the cell wall in living organisms. It explains that not all organisms have cell walls and details the role of the cell wall in providing shape, strength, protection, and support to the cells it surrounds.
Answer
Animals and many protists lack cell walls.
Animal cells and many types of protists do not have cell walls.
Answer for screen readers
Animal cells and many types of protists do not have cell walls.
More Information
Cell walls are crucial for organisms like plants, fungi, algae, and bacteria as they provide protection, shape, and structural support, but animals and certain protists rely on other cellular structures for these functions.
Tips
Confusing the presence of a cell wall with the presence of a cell membrane can be a common error. All cells have a membrane, but not all have walls.
