Types of Cells

Eukaryotic Cells

:

organisms whose cells have a nucleus enclosed within membranes, unlike prokaryotes, which have no membrane-bound organelles.

Prokaryotic Cells

unicellular organism that lacks a membrane-bound nucleus, mitochondria, or any other membrane-bound organelle

Heredity

Phenotype

Genotype.

Cell Division

the set of observable characteristics of an individual resulting from the interaction of its genotype with the environment.

the genetic constitution of an individual organism

Mitosis

type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus.

Meiosis

a type of cell division that results in four daughter cells each with half the number of chromosomes of the parent cell, as in the production of gametes and plant spores
