FC: By:Kelsey Wynne | You Have Been Invited... | The CELL-Abration
1: Every moment there are cells HAVING A PARTY. Yes a party. So we decided to visit one. What follows is what we saw and learned from one particular partying plant cell.
2: Cell Wall | First we were stopped at the door by the cell wall. (Apparently it was an invite only) | The cell wall was very rigid, but we could tell he was all about keeping the cell structured. So he let us pass. But we learned later that he wasn't the one hard to get by. He was made of cellulose, only on the outside of the cell, and was there to give the cell support and structure.
3: Plasma Membrane | Then we made our way the the plasma membrane. We knew immediately what his purpose was. | The plasma membrane was the main gate and guard to the party. He was a lipid bilayer making sure nothing got into the cell that wasn't supposed to. He said by doing this he maintained the cell's homeostasis.
4: There was so much going on inside the cell! | We entered the cell and was immediately introduced to the cytoplasm. Cytoplasm was clear, jellylike fluid that was everywhere and where the other organelles were located. The next organelle we met was the endoplasmic reticulum. She was a layer of membranes and part of her was covered in Ribosomes(which we met afterwards). She told us her job was to direct all the materials throughout the cell. She introduced us to her friends, the ribosomes, which were sometimes connected to the ER. They made up a lot of the party, but were not bound by a membrane. They are made of protein and RNA. They told me that something very important is that they are the site of protein synthesis.
6: After chatting for a while, we went over to get some snacks. This brought us to the mitochondria. Her job was breaking down food, then to release it as ATP. She was also the site of cellular respiration. Mitochondria is made of folded inner membranes and an outer smooth membrane. | Chloroplast
7: Mitochondria | The job of the chloroplast is photosynthesis. He explained that photosynthesis is so important because it changes light energy into food...which is obviously needed to survive.(And good to have at a cell party) He was a fluid filled membrane which inside of were stacks of smaller membranes. One AWESOME fact he told me that because chloroplasts like him contain green pigments, called chlorophyll, make plants green.
8: One interesting parts of our visit was to the lysosomes. They were the cell's private party cleaners. They are covered by a membrane, this is so the digestive enzymes inside the lysosome don't leave it and digest parts of the cell that don't need to be. On the inside they contain enzymes in their structure that digest old cell parts. | Lysosome
9: Next we went and talked to an organelle called the golgi apparatus. She was close to the plasma membrane. She was made of lots of layers of membranes. The tubular shaped membranes are there to modify the protein before they are sorted. Then she packages and distributes proteins to the outside of the cell. | Golgi Apparatus
10: A simple celebration, a gathering of friends; here is wishing you great happiness, a joy that never ends.
11: Meeting the Hosts | Suddenly we saw one organelle that we hadn't met yet, in the center of the cell party. It was the host, but her official name is the nucleus! This organelle was surrounded by the nuclear membrane to keep it structured and also has nuclear pores. She was the one in charge! She knew everything about the cell, because she controls all of the cell activities. | The very last organelle we met was the nucleolus. This organelle was located inside the nucleus. The nucleolus was not membrane bound and main function is to make ribosomes. Which have to make proteins according to the direction of the nucleus and DNA. Which all the other organelles depend on!
12: So this was our cell party experience. We had fun and hope you did too!
