Animal cells contain 7 different types of organelles that regulate and perform the function of each cell. The first organelle is the nucleolus, the nucleus is where all the genetic information is stored. The nucleus regulates the entire cell by holding the instructions of what is to be done and when. The second organelle is the mitochondrion, this organelle is where the energy is produced to maintain the cell. The third organelle is the smooth endoplasmic reticulum, this is where the cell produces lysosomes and detoxifies necessary fluids. The forth organelle is the rough endoplasmic reticulum or RER, here is where proteins are synthesized that are intended to leave the cell. The fifth organelle is the Golgi apparatus, this organelle modified the proteins produced within the RER and exports them outside the cell. The sixth organelle are the peroxisome, peroxisomes contain oxidative enzymes which destroy unwanted lipids. The final organelle are the lysosomes, lysosomes deconstruct proteins for reuse, additionally, they destroy unwanted proteins to protect the cell. Each organelle has a specific function that is vital for the cell to remain alive, they depend on each other and without them life as biologist know it wouldn’t be possible.
