What are the 3 different shapes, or structures, or carbon base molecules?
ddd [48]

Answer:

Carbon based molecules have 3 main structures which are

straight chain

branched chains

rings

Explanation:

The structure or shape of carbon can be a straight chain, branched chained or in the form of rings. Examples of straight chain carbon includes propane, butane and pentane. Examples of branched chain carbons include members of the alkyl group like methyl and ethyl. Ring shaped carbons form structures in the form of rings like benzene which forms a six carbon ring. All these structures are made and dependent on the ability of carbon molecules to form four covalent bonds. Enormous, complex molecules can be formed by the binding of carbon chains to carbon rings. The carbon based molecules are very important as they are the basic buiilding blocks of life. Many important molecule like the DNA, RNA, lipids are made up of carbon atoms.

Please help. What is the function of cell wall?​
Furkat [3]

Answer:

According to my search:

Explanation:

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.

Generally:

  • It protects the cell and prevents any physical damage.
  • It provides structure to the cell. It prevents osmotic bursting.
  • It protects the protoplasm against mechanical injury.
