A cell is basically made of biological molecules (proteins, lipids, carbohydrates and nucleic acids). These biomolecules are all made from Carbon, hydrogen and oxygen. Proteins and nucleic acids have Nitrogen.What are egg and sperm cells called?
gamete. Gametes are an organism's reproductive cells. They are also referred to as sex cells. Female gametes are called ova or egg cells, and male gametes are called sperm. Gametes are haploid cells, and each cell carries only one copy of each chromosome.What is a cell in the body?
Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions. Cells have many parts, each with a different function.What is coiled DNA called?
In the nucleus of each cell, the DNA molecule is packaged into thread-like structures called chromosomes. Each chromosome is made up of DNA tightly coiled many times around proteins called histones that support its structure.What is a diploid cell?
A diploid cell is a cell that contains two complete sets of chromosomes. This is double the haploid chromosome number. Each pair of chromosomes in a diploid cell is considered to be a homologous chromosome set.How many chromosomes are in a human sperm cell?
