Cells Made Easy

        Cells are important. Very important. In fact, without cells, you wouldn't be here! They are what keeps you alive. But a cell is not what it seems. Because inside a cell, there is a factory, castle, house, school, or whatever going on. There are workers, bosses, kings, walls, bodyguards, and so on. It's actually very cool, and you should be interested because, as I said before, they're what keeps you alive and well. Since what goes on inside a cell can be pretty complicated, I'll make it easy.
  • The nucleus: In a factory, the nucleus would be the boss. It controls the cell. It's usually round and darker than the rest of the cell.
  • Cell membrane: In a castle, the cell membrane would be the bodyguard. It protects the inside of the cell. The cell membrane supports and gives a cell its shape. It also controls the movement of materials(food, water, waste) into and out of a cell.
  • Cytoplasm: It's basically the wall of the cell. The nucleus floats in the cytoplasm. Most of the cell is made up of cytoplasm. Most of the cells activities take place in the cytoplasm.
  • Mitochondria: The mitochondria is the powerhouse of the cell. It produces the cells energy. They're rice shaped structures that are so small, you need an electronic microscope to see them. They break down food to make energy for the cell.
  • Lysosomes: In a school, the lysosomes would be the janitors, or clean up crew. Lysosomes are small, round structures that are involved with the digestive activities of the cell. They also digest old cell parts. They contain enzymes that break down large food molecules into smaller ones.
  • Vacuoles: They are like storage bins. They store food, wastes, and some hold water.They pump extra water out of the cell.
  • Ribosomes: Ribosomes are small, round structures in the cytoplasm . They make protein needed for cell growth and repair . They can help fight certain diseases. Ribosomes are the cells most numerous organelles.
        I know, I know. It's not easy. But it is interesting. I couldn't make it so easy that you could do it in your sleep, but nothing is so simple. It takes a lot of brain power to memorize stuff, so I hope you have some to spare. If you want to learn more about cells, simply go to youngro-jalenguy's blog, or to SuperSara's. Peace, me out!
