Answer:
The life cycles of all sexually reproducing plants follow a pattern of alternation between a haploid, sexual generation called gametophyte with a diploid, asexual generation called sporophyte.
This phenomenon of alternation between gametophyte (n) and sporophyte (2n) in the life cycle of a plant is called alternation of generations (Hofmeister, 1851).
Alternation of generations is of two types- isomorphic and heteromorphy. In isomorphic (or homologous) type both the alternating generations are morphologically similar, while in heteromophic (or heterologous) type of alternation of generations both the generations of life cycle are morphologically dissimilar.

Answer:
Lipid bilayer can be defined as a polar membrane, which composes two layers, made up of lipid molecules. It shows both hydrophobic (due to non-polar tails of lipid molecules) and hydrophilic (due to polar heads of lipid molecules) nature, and hence is known as of amphipathic nature.
Lipid bilayer shows selective permeability as not all molecules can cross the lipid bilayer. It can pass non-polar, small, uncharged molecules due to its hydrophobic core, such as oxygen, water, urea.
On the other hand, polar, large, or charged molecules, such as glucose, amino acids, and ions cannot pass through lipid bilayer. These molecules require transport proteins for their transport, which are embedded in lipid bilayer.
he lipid bilayer has unique properties. They are formed in sheet-like structures that contain both a hydrophilic and a hydrophobic moiety. The membrane is composed of lipids and proteins and sometimes even carbohydrates. There are two different membrane proteins in the lipid bilayer.
Genetic variation. C is the answer
Yes, a plant would as long as a living creature is in the area to exchange oxygen and carbon dioxide. It is not totally necessary for other plants to be in the immediate vicinity but is necessary for all living things to live. As mentioned before carbon dioxide and oxygen must be exchanged.
