What is body cell?
1 : somatic cell —opposed to germ cell. 2 : the one of two cells produced by division of the generative cell in the pollen grain of certain gymnosperms that in turn divides to produce two male nuclei or cells.
Are body cells diploid or haploid?
Diploid is a cell or organism that has paired chromosomes, one from each parent. In humans, cells other than human sex cells, are diploid and have 23 pairs of chromosomes. Human sex cells (egg and sperm cells) contain a single set of chromosomes and are known as haploid.
What are cells called cells?
Cells got their name from an Englishman named Robert Hooke in the year 1665.

What are the three important parts of a cell?
Complete answer: There are three major parts of a cell: a cell membrane, a nucleus, and a cytoplasm between the two. There are hundreds or even thousands of complex structures of fine fibers or minuscule but distinct structures inside the cytoplasm, called organelles.
What are essential cell parts?
The vital parts of a cell are called “organelles.” Among the most important are the nucleus, vacuoles, and mitochondria, all of which are enclosed within the cell membrane and immersed in cytoplasm. Each organelle performs a specific task that helps keep the cell alive.
What is cell and its parts and functions?
Each cell is surrounded by a membrane and contains parts called cellular organelles. Each cellular organelle has a specific function. Some parts of a cell are involved in converting energy from nutrients in the food you eat into a form of energy that the cell can use.
