Our comparison is between the fuse box of the house and the nucleus. The nucleus of a cell has three parts; nucleus envelope, nucleolus and nucleus. The nucleolus is inside the nucleus and the nuclear envelope surrounds everything. The nucleolus is filled with a gel-like substance, called nucleoplasm. The nucleus is like the “brain” of the cell, and the fuse box is like the “brain” of the house. They both have the same thing in common because they both control if we didn't have a nucleus in the cell, it wouldn't be able to work, and if we didn't have a fuse box in the house it would be a lot of things wouldn't work. Our comparison is between mitochondria and the power lines that power the house. Mitochondria energy is stored in two types of molecules: carbohydrates and lipids. Carbohydrates have quick energy and lipids have long-term energy. Both have the same thing in common because they both emit energy. If we didn't have mitochondria, cells would have no energy. If we didn't have power lines the house would be powerless and nothing would work. Our comparison is between the ribosome and the electrical outlets in the house. The ribosome of a cell has four types of macromolecules. These four types are carbohydrates, lipids, nucleic acids and proteins. Protein is vital to cell function because proteins do just about everything. Some of the things they do are signaling, structure, communication, transport movement. So our analogy is good because both are there to do whatever is needed. Power outlets make everything plugged in work, and the ribosome does almost everything the cell needs. Our comparison is between the endoplasmic reticulum and a home oven. The ER i...... middle of paper ......n in nucleotides. The inside of a lysosome is very acidic. Acid helps break things down; the acid is very toxic to the rest of the cell. Catabolism is breaking things down into smaller parts; anabolism consists of building molecules from smaller parts. Catabolism+anabolism=metabolism. Metabolism is the rate at which fuel is broken down and rebuilt into usable molecules. I'm comparing eyelashes to a ceiling fan in a house. Cilia are hair-like projections of a cell membrane. The hair-like projections make the cell appear hairy. The function of cilia is to flap in unison to move things out of the cell. Cilia increase the surface area of ​​a cell and are common in multicellular organisms. I've compared eyelashes to a fan because they both move things. The fan moves the air in a house in circular motions. Cilia move things out of the cell with its hair like projections.
