the structure and function of each of the eukaryotic organelles. ”A eukaryotic cell is sectioned by internal membranes into different functioning categories called organelles. For example‚ the nucleus houses DNA‚ the genetic component that controls the cells activities. (Boundless. “Introduction” Boundless Biology). The Cytoplasm is the material between the cell membrane and the nucleus. It has a lot of responsibilities within the cell. It contains enzymes for breaking down waste and also gives the

largest and most prominent organelle‚ occupying about 10% of the total volume of a cell and can have a varying number of nuclei. It could be uni-nucleate – single nucleus; bi-nucleate – two nuclei or even multi-nucleate. The nucleus separates itself from the surrounding cytoplasm by the double membrane around it called the nuclear envelope‚ this helps to regulate the flow of certain substances going in and out of the nucleus. At varying points around the nucleus‚ the two membranes fuse together to create

The Nucleus: In the kingdom the nucleus is the king. The nucleus is a membrane-bound organelle found in the center of the cell that contains all of the genetic information‚ and DNA and controls the rest of the cell. To the kingdom the nucleus is the king because of how he controls the kingdom and is responsible for the wealth of the town through his actions. Additionally not all cells have a nucleus. Just as not all kingdoms have a king. The Nuclear Envelope: The nuclear envelope is similar to the

The constellation is visible with the naked eye and can be seen by everyone in the world‚ wherever they are.

The Cell membrane surrounds all living cells and is the most important organelle‚ there is also a similar plasma membrane that surrounds all the organelles except for the ribosome. The membrane controls how and what substances can move in and out of the cell/organelle The structure of the membrane is often referred to as the “Fluid Mosaic Model”; this is because of the way it is structured It is composed of phospholipids‚ proteins‚ and carbohydrates‚ which are arranged in a fluid
