What are the 2 types of cell walls in plants?
Plant cell wallsThe primary cell wall, generally a thin, flexible and extensible layer formed while the cell is growing.The secondary cell wall, a thick layer formed inside the primary cell wall after the cell is fully grown.
It is not found in all cell types.
The middle lamella, a layer rich in pectins..
Which organism has no cell wall?
Examples of bacteria that lack a cell wall are Mycoplasma and L-form bacteria. Mycoplasma is an important cause of disease in animals and is not affected by antibiotic treatments that target cell wall synthesis. Mycoplasma acquire cholesterol from the environment and form sterols to build their cytoplasmic membrane.
What can a cell wall be compared to?
The cell wall in a plant cell is like the frame on a car. The frame supports the car as the cell wall supports the plant.

What 4 types of organisms have a cell wall?
The main kinds of organisms that have cell walls are plants, fungi, and certain prokaryotes (bacterial type cells). In plants, cell walls are mainly comprised of complex polysaccharides (sugar-based polymers) molecules such as cellulose, hemicellulose, and pectin.
Why is a cell like a city?
Like the organs in your own body, each one carries out a specific function necessary for the cell to survive. Imagine the cells as a miniature city. The organelles might represent companies, places, or parts of the city because they each have similar jobs.
Do humans have a cell wall?
A cell wall is a fairly rigid layer surrounding a cell located outside of the plasma membrane that provides additional support and protection. They are found in bacteria, archaea, fungi, plants, and algae. Animals and most other protists have cell membranes without surrounding cell walls.
What is an analogy for cell wall?
The cell wall is like a bullet proof vest, because a cell wall protects the cell like a bullet proof vest protects its user.
What is DNA in a cell City?
The Town hall represents the nucleus because like a town hall, the nucleus directs all the cellular activities. … In Springfield, the museum represents the DNA, because the DNA contains all the information about the cell, and the blueprints too.
What does a cell wall do?
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
What cell organelle is called the Big Boss?
nucleusThe nucleus is the control center of the cell. Think of it like cell headquarters. The big boss, our DNA, works there and directs the rest of the cell’s activities.
