The Cell Theory states that: 1) All organisms are made up of one or more cells and the products of those cells. 2) All cells carry out life activities (require energy, grow, have a limited size). 3) New cells arise only from other living cells by the process of cell division.tructure-a bilipid membraneous layer composed of proteins and carbohydrates. It is fluid like. Function-the cell membrane separates the cell from its external environment, and is selectively permeable (controls what gets in and out).
The anatomy and structure of the five sense organs of the human body: vision, hearing, smell, taste, and touch.
A bit of a joke - but senses (including your sense of smell) are very important. Your senses let you know what is going on in the world around you.
