Plant+Cells+-+EM

=Introduction= Have you ever thought about how you never run out of oxygen? When you take a deep breath, you breath in oxygen and you feel energized. Ever wonder how that oxygen keeps getting into your lungs? Well you can thank plant cells for constantly providing oxygen for us. This is a process called photosynthesis. The structure of a plant cell helps out with what to bring in the cell and what not. Just like us, the plant cell has a shield to protect it from diseases. Everything that was mentioned briefly, helps the plant produce oxygen so we'll be alive. toc =Photosynthesis= Plant cells need to have chemical energy from the sun to create food. The plant cells create food which is called glucose from water and cO2. Then after this, the plant cell starts photosynthesis. This happens in the chloroplast. The mitochondria is what makes the food. The mitochondria takes in the energy and nutrients from the sun and will store it in the vacuole along with the water, and then it turns it into glucose for the plant to eat and stay alive. The plant cell won’t stop photosynthesis since the sun and nutrients won’t go away or die anytime soon. All of photosynthesis happens in the chloroplast and the energy and nutrients are held in the vacuole, which could store a lot of food and water for the plant cell to live and to keep us living. Plant cells function and photosynthesis are very important to the world. =Structure of a Plant Cell= The plant cell has a unique feature. Unlike animal cells the plant cell has a cell wall. The cell wall is a stiff wall that surrounds the cell membrane and protects the cell, allowing which is good to enter the cell or which is bad that can damage the cell. The cell wall gives the plant a rigid, boxlike shape. The plant cell also has a bigger vacuole than an animal cell. (An animal cell's vacuole is very small) The plant vacuole is found in the cytoplasm and will store water, waste products, and food for the cell to live on. Like animal cells, the plant cell has a cell membrane that controls what substances can enter and leave the cell. (Just like the cell wall). The cells structure is very important and special to the plant cell. Without a cell wall or membrane, the plant cells would probably die from diseases. =How Plant Cells Benefit Humans= The plant cell has a wall around it called the cell wall and it protects what goes inside the cell and what comes out of it. A human has a shield and a defense system that protects us from disease and bad things that can enter the body. The plant cell and body have a lot of things in common. They both have a defense system and both have a wall/barrier that can protect itself from bad things and diseases that can be bad for it and can harm it. Plants can get cancer too as well as people. This can kill the plan and human or can harm it and it could get very week. This shows how plant and human functions/structures are very important and special to us to have because without them, the plants and humans would die quicker because of diseases we can't get rid of. =Conclusion= Now how do you feel after learning what to thank for leaving us oxygen to live? Now you that you know more about plant cells, you know how important the photosynthesis is, how important the cell wall and membrane are, and how plant shave a defense system just like we do. Now you also know how plant cells and people are alike in more than one way. All of these features in a plant cell are very important to them and to us. The plant cell keeps itself living, but also keeps you living. That's why plant cells are very important to have in an environment and to us. =References=
