What wraps up the nucleus area would be the nuclear membrane. This membrane is known as the nuclear envelope. It 's found in both plant and animal cells. This is what surrounds the nucleus. These are selectively permeable, meaning this membrane choses certain molecules to enter or pass through the nucleus. Another organelle would be ribosomes. Ribosomes are in both plant and animal cells. Ribosomes are made up of proteins and RNA. It 's often called the “protein factories” for the cell. Ribosomes join together with with amino acids and those two together is what makes proteins. They’re either found unattached in the cytoplasm or attached to rough E.R. E.R stands for endoplasmic reticulum, these are a set of tubes or membranes and they connect to the nuclear envelope and cell membrane. The function of endoplasmic reticulum is the synthesis of cell products and helps transport materials through the cell. There are two kinds of E.R, rough and smooth. Rough E.R is found to have ribosomes along it 's surface. The ribosomes are what produce the proteins. These particular proteins are membrane proteins and the protein for the export of the cell. They are then passed through the interior of the rough E.R to be transformed then sent out. …show more content…
Microfilaments and microtubules join together and that 's what forms cytoskeleton. The cytoskeleton helps with cell shape, it connects to just about every part of the cell membrane. Lysosomes and peroxisomes are shipped to go help with the digestion process. Lysosomes contain digestive enzymes. These are small and round, with a membrane. The cell takes in food through photosynthesis, lysosomes are what break down larger food molecules into smaller ones and then it digests the old cell parts. There are many ways that peroxisomes are like lysosomes. They are small vesicles that are found around the cell. They’re single membraned that contain digestive enzymes for break down toxic materials. They hold a different kind of enzyme though. The peroxisomal enzymes require oxygen. Lysosomal enzymes are in areas that have poor oxygen and low pH level. Peroxisomal absorb nutrients and digests fatty acids. It also plays a part in amino acids break down process in cholesterol synthesis. Along with the cytoskeleton comes cilia, flagella, and centrioles. They are all 3 made up of microtubules. Centrioles are only found in animal cells and they appear as paired structures located near the nucleus. They’re seen during cell division forming mitotic spindle. Centrioles help with pulling chromosome pairs away from each other to the separate ends of the cell. Cilia and flagella both move cells and fluids. Cicilia appear to be shorter but there seem to be more of them.
