Answer:

The plasma membrane of a cell is organised as:

Two layers of phospholipids, with their polar hydrophilic heads facing away from each other.

Explanation:

Plasma membrane forms the external boundary of the cell.
The Plasma membrane is selectively permeable and allows only selected solute molecules to pass through it.
The Basic structure of the plasma membrane is the lipid bilayer.
This bilayer is composed of two leaflets of amphipathic lipid molecule.
The polar heads of the molecules are in contact with the intra- or extracellular aqueous phase while the non-polar hydrophobic tails face each other forming the hydrophobic interior of the membrane.
The three clases of lipids present in lipid bilayer are- phospholipids, glycolipids and sterols.

<h3>WHAT IS A HETEROZYGOUS CROSS</h3>

A heterozygous cross is a cross between two individuals that are heterozygous for two genes.

According to this question, white (W) fruit color is dominant over yellow (w). If two white-fruited individuals with genotypes that are unknown are crossed i.e. Ww × Ww.

The offsprings of this cross are as follows:

Therefore, the probability of obtaining a yellow-fruited plant from the cross is ¼ or 25%.
