Ricky notices a similarity between a fried egg and the diagram of a cell.

The cell organelles which Ricky is likely to associate with the parts of the egg are NUCLEUS AND CYTOPLASM.

The nucleus of the cell correspond to the egg yolk (yellowish part of the egg) while the cytoplasm of the cell correspond to the albumin part of the egg.  The nucleus and the cytoplasm carry out vital roles in cells. The nucleus serves as the control point of the cell while the cytoplasm serves as the fluid, in which all cell organelles are located.

Explanation:

The resemblance of fried egg with a cell is in the following way :

1. The outer layer of fried egg-Cell membrane

The cell is enclosed by a hydrophobic layer called a cell membrane made of fatty acids.  

2. A whitish portion of egg- Cytoplasm

The living component of a cell containing gel-like fluid with cell organelle.

3. Yellow yolk- Nucleus

The organelle containing genetic material of the cell which is the main centre of a cell.

Thus, the outer layer of fried egg-cell membrane, the whitish portion of egg- cytoplasm and yellow yolk- the nucleus is the correct answer.
