Are eggs (chicken/ostritch) a single cell?

I wish people won't answer science questions if they weren't sure of the answer. The answer is Yes. An egg (chicken, ostrich, partridge, pigeon, etc) is a SIGNLE cell just like ovules for mammals. And just like mammals, an egg from these animals is dropped whether it's fertilized or not (it's the equivalent of the 14th day of a woman's menstrual cycle).

Also, if you carefully break the egg, you'll notice a VERY easily spotter membrane; that's the equivalent of a cell wall. The shell is just a protection (mainly formed of Ca) because the egg goes out of the body (as opposed to a female ovule that stays in).

I hope this helps.

Yes, they are a single cell. Chicken/ostrich eggs are some of the largest single cells that exist. Even the human egg cell is the biggest in the body.

The egg is single celled if it hasn't been fertilized. If it has, then the egg is an embryo. All Embryos have more than one cell.

Clostridium, is very correct and I was getting mad reading the people who wrote that it is not....WHY WHY do you answer a question if you dont know the correct answer????? The correct answer is YES

Excerpt from wikipedia...... The 1.5 kg ostrich egg contains the largest existing single cell currently known, though the extinct Aepyornis and some dinosaurs had larger eggs. The bee hummingbird produces the smallest known bird egg, which weighs half of a gram. The eggs laid by some reptiles and most fish are even smaller, and those of insects and other invertebrates are much smaller still.

No, not really. The white of the egg is the equivalent of human amniotic fluid, which the embryo (whatever its size) floats in. The yolk sac is filled with nutrience the embryo needs to grow. The embryo is connected to the yolk sac with very short cord. And as the embryo grows the yolk sac gets depleted.

Humans also have a yolk sac, which can be seen at early stage of development.

Also most eggs we eat actually doesn't have an embryo. Chicken lay eggs regardless if it is fertilized or not.

What! Someone thinks they are a single cell? Come on.

The chicks start as single cells, just like us. As they continue to grow, their cells are multplying. So a child, before it born is a single cell organisim.

Have you ever cracked an egg and seen the milky icky stuff? That would be a chick, if left to grow.

Single cells, Give me a break.

****sorry, I'm a little crabby today*****

An unfertilized egg is a single cell. A fertilized egg is ballut which some but not all Filipino people enjoy gladly for lunch with some salt.

Yes. In fact, at 1.5 kilograms, the ostrich egg is the largest single cell in the world.

the inside of an ostrich egg is a single cell, that's right

Yes,

An egg is a single cell, albeit very, very large.
