Cell Structure & Organization
Cells are the building blocks of life.
The Cell Theory states that
Each cell has smaller structures called organelles which vary in number, size and types between different types of cells. In specialized cells, the shape and organelles are closely related to function.
Cells are organized into tissues, and further into organs, organ systems and finally organisms. Learning Objectives
