the egg is larger than the sperm cell
Just before hatching begins, the air cell expands to approximately 30% of the internal volume of the egg. As hatching begins, the beak of the embryo penetrates the inner shell membrane where it forms the inner wall of the air cell. The lungs begin to function, inhaling the air from the air cell.
Several hundreds of millions of times larger in volume, if not even larger.
The smallest egg cell is that of a fruit fly. It measures around 0.12mm in length.
A fertilized egg cell is when a sperm enters an egg. The result is a fertilized egg cell, or a zygote.
Eggs float when they are older because air enters the eggshell as it ages, creating a larger air cell inside. This means the egg is less fresh.
The air space in an egg serves as a buffer for the developing embryo, providing it with a supply of oxygen as it grows. This space forms at the larger end of the egg as moisture and air seep in through the porous shell, and it expands as the egg ages. Additionally, the air space helps maintain the egg's internal pressure and can indicate freshness; a larger air space typically signifies an older egg.

As an egg ages, its moisture content decreases and air enters through the porous shell, leading to the air cell inside expanding. The egg white becomes thinner and the yolk membrane weakens, making it more prone to breaking. The egg may also lose some of its freshness and flavor as it ages.

Egg cells are the biggest: you could only fit one on the head of a pin. But I'm not sure if a sperm cell is bigger than a red blood cell or vice versa.
The size of egg is larger than sperm because the the sperm enters inside the egg and egg has to accommodate the sperm. And egg contains fats and nutrients in order to feed zygote in case of pregnancy.
Animal cells are larger; an ostrich egg is only one cell.
When a raw egg floats, it means that it is no longer fresh and has likely gone bad. This is because as an egg ages, the air pocket inside it grows larger, causing it to become less dense and float in water.
The air cell pocket in a chicken egg serves as a reservoir of air that provides the developing embryo with oxygen as it grows. It forms as moisture and air seep through the porous shell during incubation, creating a space at the larger end of the egg. This pocket also helps regulate temperature and humidity, which are crucial for proper development. As the embryo develops and consumes the yolk, it relies on the air cell for respiration before hatching.
When eggs float, it usually means that they are old and have lost moisture through their shells, creating a pocket of air inside. This can happen as the egg ages and the air cell inside expands. It is a sign that the egg is not as fresh and may not be good to eat.
