Brain of the Cell The nucleus is literally a membrane-bound organelle and is surrounded by a double membrane. I feel that the nucleus is of the greatest importance in the cell because it is the control center that oversees the metabolic functioning of the cell and it directs all the cells activities. The nucleus is like the head of the cell and without a head the rest of the body is useless. It is the largest organelle and within the nucleus is the DNA responsible for providing the cell with its unique

we decided to investigate an important fact that normally goes unquestioned: why are cells so small? Would it be more efficient if everyone were just made up of one or two huge cells? A source of energy and molecules are required by all living organisms‚ which means that the amount of the cell that is able to receive molecules is important. The group’s hypothesis was that “cells are small because small cells have a larger surface area to volume ratio”‚ which is important because a larger surface area

What Is So Important About Cells? Cells are the most basic building block of all life as we know it. But what makes cells extremely important to living organisms‚ and why do we need cells anyway? A cell is “a usually microscopic structure containing nuclear and cytoplasmic material enclosed by a semipermeable membrane and‚ in plants‚ a cell wall; the basic structural unit of all organisms.” But what makes cells extremely important to living organisms‚ and why do we need cells anyway? Cells are made

The reason is that carbohydrates‚ proteins‚ lipids‚ and vitamins are all organic compounds(contains carbon) . The structure of minerals is very simple‚ usually nothing more than a molecule‚ or molecules. Most of the minerals in a diet come from eating plants and animals or from drinking water
