MEIOSIS
Meiosis refers to the type of cellular division that normally occurs as part of sexual reproduction when the new daughter cells receive that haploid (n) number of chromosomes.

PROKARYOTE
Organism (which is often also reference to a given type of cell) that lacks the membrane-bounded nucleus
and organelles containing membranes that are typical of eukaryotes.

EUKARYOTE (EUKARYOTIC CELL)
Cell that contains a well-defined and membraned nucleus and membranous organelles. These structures are normally absent in prokaryotic cells or organisms.

ORGANELLE
Membranous microscopic structures found in cells having specific structures and functions for example lysosomes, mitochondria, nucleus and ribosomes.
