To Appreciate the Nature of Life We Must First Understand the Cell
Life itself is amazing. It surrounds us on a daily basis from the ants in our window seal, the squirrels on the power line, to the bacteria we all have in our mouths and on our bodies. Life is indeed a gift. Every life that comes into this world is made up of cells, life of humans, plants, and animals. I know that to understand the nature of life we must first comprehend the cell, its parts, and organelles. There are two different types of cells, including prokaryotic and eukaryotic. Living bacteria is an example of something that contains prokaryotic cells.
Eukaryotic cells are in just about everything, all humans and all animals. I must say that the eukaryotic cell is way more complex than the prokaryotic. A prokaryotic cell does not even hold a nucleus, which is the brain of the eukaryotic cells. Human and animals cells cannot be developed without prokaryotic cells. Even though these two different types of cells are very different they also are somewhat similar. Both contain ribosomes, cell membranes, and cytoplasm. Plant cells are eukaryotic cells but there are items that definitely set them apart. Cell walls, chlorophyll, and vacuoles are difference between the two.
By plant cells having these different organelles, they function in a unique order. Each organelle in the cell do different task. Supporting all organelles in the cell is the cytoplasm. Cytoskeleton maintains the shape and gives it strength. The nucleus is a cell’s brain and operating system. The mitochondrion develops energy through cellular respiration. Ribosomes produce protein, while the nucleolus is what makes ribosomes. The vacuole is the largest organelle and it stores food, wastes, and water. The cell wall which is in all cells except animals, protect the cell and allows elements such as water, oxygen, and carbon dioxide to enter.
Endoplasmic reticulum is what carries materials through the cell. Lysosomes are what break down large food molecules into smaller ones. Using energy from the sun to produce glucose is the chloroplast (which can only be found in plant and algae). Cells make up life. We cannot live or operate without them. Each individual cell is like groups of workers that work together. Without the nucleolus which makes the ribosomes, we would not have any protein. And without protein, we as humans could not be healthy. Humans need cells and all their many organelles. Without cells, there is no life.
