Lol, and stop cheating on your homework page 26 :D
Ovum is the largest cell in the human body and must carry nutrients to survive upto 72 hours if unfertilised. If fertilizer, it must go and reach the uterus and survive. It has a lot of work to do if fertilized. Hence robust and bigger.
In the sperm:
- the chromosomes are packed tightly together in the nucleus.
-it is 60 micrometers long.
-has a tail to help it to swim.
-has no membrane.
-has no cytoplasm or jellycoat.
-is separated into three parts;the head,middle piece and tail.
In the ovum:
-the chromosomes are more spread out.
-it is 120 micrometers wide.
-has no tail.
-has a membrane.
-has a cytoplasm and jellycoat.
-is not separated into several parts.
the sperm cells need to be able to see the egg cell
assuming you mean a sperm and not a cingular cell of a sperm, it is about 1/18th the size of an ovum.
the egg is larger than the sperm cell
the egg is larger than the sperm cell
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.
The egg is larger than a sperm because it has the cytoplasm of all four of the produced cells (the other cell components become polar bodies).
because Eggs are thousands of times larger than sperm, and it usually only requires one egg, whereas a male with 1 sperm count would have pretty much a 0% chance of having children.
A sperm cell is a different shape than a regular body cell. It sort of looks like a lemon with a tail. The main difference the between sperm cells and regular body cells is that sperm cells only have 23 chromosomes compared to the 46 in normal body cells do to undergoing meiosis.
No, chromosomes are smaller than cells. Chromosomes are found in the nucleus of cells which codes for the synthesis of proteins.
A lot bigger. The ovum is 120 µm in diameter and the sperm cell is about 1 µm in diameter (not counting the tail).
Yes it is alot larger.
The egg consists of food for the embryo for the first four days. In addition, it also needs to accommodate the sperm, which is why it is longer than the sperm.
