organelles of a standard undifferentiated cell are as follows. The cytoplasm is the watery substance that makes up the bulk of the cell with organelles in it. It consists mainly of water with dissolved substances such as amino acids in it. The endoplasmic reticulum (ER) is a set of flattened cavities lined by a thin membrane. It is where many substances are made in the cell. It also works as a transport system in which substances can move through from one part of the cell to another. There are 2 types

Reviewing Ideas and Using Concepts: P.258-259 Reviewing Ideas: 1. Describe the function of tRNA‚ mRNA‚ and rRNA. The function of tRNA is to delivers amino acid to ribosomes during translation in the order specified by the mRNA. The function of mRNA is to specify which amino acids must be placed during protein synthesis or translation. The function of rRNA is just to become part of the ribosomes. 2. In what situation does RNA play a role similar to enzymes? RNA is like an enzyme when it

Mitochondria - Take in glucose via proteins that pass the plasma membrane and after it journey through the cytoskeleton to the mitochondria inside the cytoplasm. Endoplasmic Reticulum - Both ER types are covered in making essential cellular segments. For the most part in charge of the combination and handling of proteins that are either emitted from the cell or that end up stuck in the plasma film. The lipids made in the SER are joined with phosphorous to make phospholipids‚ the most inexhaustible
