It enables photosynthesis by facilitating primary growth of the plant
A. Evolution is a scientific theory, and scientific theories have many hypothesis and experiments that support their findings.
Lipid bilayer model was proposed for its structure but it was modified and new structure is according to fluid mosaic model. Plasma membrane is selectively permible as it selects small molecules like lipid etc (composition is also of lipid and as solubility principle like dissolve like) so large and charged molecules like plasma and ion can't pass through it. Lipid are in form of layer so at the chain when ever other phosphate group attach the place conjugate molecule (phospholipid ) formed
DNA and RNA both produce proteins, but RNA copies itself and moves out of the nucleus while DNA stays inside the nucleus and produces proteins. Also DNA helps more in cell division, while RNA helps in making proteins.
