Where is the cell membrane located in the cells that do not have cell walls?
Animal cells are the type of cells that do not have cell walls. The location varies depending on where the cell functions.
What purpose do diatoms cell walls serve?
Movement --- Diatoms are able to move by secreting chemicals out of small holes in their cell walls and gliding on the slime:)
Are cell walls considered organelles in a cell's structure?
No, cell walls are not considered organelles in a cell's structure. Organelles are membrane-bound structures within a cell that have specific functions, while cell walls are rigid structures found outside the cell membrane that provide support and protection to the cell.
How does a virus affect cell functions?
DNA, then RNA - it replicates itself and spreads. In doing so, breaks cell walls.
What functions do enzymes in Cells serve?
They control all of the Cell's biochemical reactions.
What functions do proteins have in the cell membrane?
Receptors, Selective Channels and pores
Is cholesterol a type of cellulose?
No. Cholesterol is a steroid alcohol and cellulose is a polysaccharide (a complex sugar).
Do birds have cell wall?
No, birds do not have cell walls. Unlike plant cells, which have rigid cell walls made of cellulose, bird cells have flexible cell membranes. This allows for greater mobility and adaptability in their tissues, crucial for functions such as flight.
Does a wolf have a cell wall?
No, wolves do not have cell walls. Cell walls are a feature of plant cells, not animal cells like those found in wolves. Wolves have cell membranes like other animals that serve to protect and maintain the integrity of the cell.
What functions do membrane proteins serve in biological systems?
Membrane proteins serve various functions in biological systems, including transporting molecules across the cell membrane, acting as receptors for signaling molecules, and providing structural support to the cell membrane. They also play a role in cell adhesion, cell communication, and cell recognition.
The chemical found in tears and saliva that hydrolyzes the peptidoglycan in certain bacterial cell walls is what?
The chemical found in tears and saliva that hydrolyzes the peptidoglycan in certain bacterial cell walls is lysozyme. Lysozyme functions as an antimicrobial by breaking down the cell walls of bacteria, leading to their destruction.
How do the cell walls of fungi differ from the cell walls of plants?
Fungal cell walls are primarily made of chitin, while plant cell walls are primarily made of cellulose. Fungal cell walls do not contain lignin, which is found in plant cell walls and provides rigidity. Additionally, fungal cell walls do not have chloroplasts like plant cell walls do.
