Answer 1

In the alphabet, the basic unit is a letter. In all living things, the basic unit is a cell. The smallest living things are single cells that carry out all of the processes of life by themselves. Two of the basic functions of cells are getting energy and getting rid of waste.

Getting Energy
When you are getting a little sleepy during the day what do you do. Many people grab a candy bar or a soda. Why? One reason is they both contain sugar. We call this energy. Animals obtain energy by eating things. Anything that animals eat is digested and converted to sugars. Sugar is the basic source of energy. Whatever you eat for energy gets converted to sugar. Now, we also need other things like proteins, fats, vitamins, minerals and fiber. All of these things that we eat and need are actually used at the level of a cell. Each cell in your body needs energy and when you eat foods your body breaks it down into smaller and smaller pieces until your cells can bring them into your body through the process of osmosis. This entire process of getting food and breaking it down and your cells using the energy is called digestion and respiration.

Plants also need energy but you don't often meet a sunflower getting a candy bar at the vending machines. Plants get their energy differently than animals. Plants have a special chemical in their cells called chlorophyll. This chemical along with a cell organelle called a chloroplast allows plants to use carbon dioxide, energy from sunlight, and water to make sugar. This process is called photosynthesis

I would refer you to Lesson 7: Cells

This given copious details of the process.

Answer 2

Red blood cell pick up oxygen from the lungs, and transport it to every cell in the body. At the same time, CO2 is removed from these cells and transported back to the lungs (exhalation). Thats the simple 25 cent tour.
