The presence of a cell wall provides structure, support, and protection to the cell. It helps maintain the shape of the cell and prevent it from bursting when exposed to hypotonic solutions. Additionally, the cell wall plays a role in defense against pathogens and provides a barrier to regulate the movement of substances in and out of the cell.
the plant cell wall looks like a brick wall that has been covered in slime.
The cell membrane has a fluid mosaic structure consisting of a phospholipid bilayer and protein molecules scattered in it. The evidence has been obtained by freeze fracture.

If you looked under a microscope and saw a cell with a cell wall and chloroplasts you would know that the cell is a what?
You would know that the cell is a plant cell. The presence of a cell wall and chloroplasts are unique to plant cells.
Which part of bacteria cell is most involved in gram stain?
The cell wall of a bacterial cell is the most involved in the Gram stain because it determines whether the bacteria will appear purple (Gram-positive) or pink (Gram-negative) after staining. The composition of the cell wall, specifically the presence of peptidoglycan, influences how the stain interacts with the bacteria.
Which is NOT an important structural feature on the surface membrane of an animal cell?
One structural feature that is not important on the surface membrane of an animal cell is the presence of a cell wall. Animal cells lack a cell wall, unlike plant cells which have a rigid cell wall for structural support and protection.
Do all bacteria have a cell wall?
No, not all bacteria have a cell wall. Bacteria can be classified into two main groups based on the presence or absence of a cell wall: Gram-positive bacteria have a thick cell wall, while Gram-negative bacteria have a thin cell wall surrounded by an outer membrane. Some bacteria, like Mycoplasma species, lack a cell wall altogether.
How can you tell if its a animal cell or plant cell?
You can tell if it's an animal cell by the presence of centrioles and lysosomes, which are not typically found in plant cells. Plant cells, on the other hand, contain chloroplasts and a large central vacuole, which are absent in animal cells. Additionally, plant cells typically have a cell wall, whereas animal cells do not.
What would distiguish a bacterial cell from an animal cell?
presence of a cell wall
What features indicate that a cell is a plant cell and not an animal cell?
lack of a cell wall and chloroplasts and the presence of centrioles
If you looked under a microscope and saw a cell with a cell wall and chloroplasts you would know that the cell is a what?
You would know that the cell is a plant cell. The presence of a cell wall and chloroplasts are unique to plant cells.
How do protoplast differ from L form?
Protoplasts are formed from gram-positive cells in the presence of lysozyme, which destroys the cell wall. L forms are gram-positive or gram-negative bacteria that do not make a cell wall. Therefore, L forms never had or made a cell wall as opposed to protoplasts which used to have a cell wall, but no longer do because it was destroyed. Penicillin can be used to destroy the cell wall of a bacterial gram-positive cell and form a protoplast, but in the presence of Penicillin, if a new bacterial cell is forming and cannot create a cell wall, then it will become an L form.

Do all cells have cell wall?
No, not all cells have a cell wall. Plant cells, fungal cells, and bacterial cells typically have cell walls, while animal cells do not. The presence or absence of a cell wall depends on the organism and its specific cellular structure.
How can a mycoplasma be recognized?
Mycoplasma organisms do not contain a cell wall. Thus, traditional cell staining techniques (which require the presence of a cell wall), do not highlight the organism. A special staining technique is required for visualization.
What is one way plants cells are differ from animals cells?
One way plant cells differ from animal cells is the presence of a cell wall in plant cells that provides structural support and protection. Animal cells do not have a cell wall but instead have a flexible cell membrane for support.
What fundamental traits did lennaeus use to separate plants from animals?
Autotrophic mode of nutrition Presence of cell wall Presence of alternation of generation
Is the absence of cell wall in animal cell necessary?
The cell wall is essential part of animal cells.it creates a barrier so that the cytoplasm remains in the cell and lets only the useful substances inside the cell i.e. it is semi permeable.without the cell wall the cell material would disperse and harmful substances would enter it and it will die. The presence of cell wall in animal cells is necessary,not the absence.

If you looked under a microscope and saw a cell with a cell wall and chloroplasts you would know that the cell is?
A plant cell. The presence of a cell wall and chloroplasts is a characteristic feature of plant cells. Cell walls provide structural support while chloroplasts are responsible for photosynthesis.
