Within vascular plants, specialized tissue called “phloem” conduct sugars and other nutrients. (Similar to how humans have veins and arteries to transport blood and nutrients.) Phloem consists of the cells that act as the conductors of these nutrients, as well as “companion cells,” which provide energy to the conductor cells.

What organelles might you see more of in these plant “companion” cells? Why do you think that is?

Protein synthesis actually begins in the nucleus when transcribes a single gene on the dna molecule is copied. the process of copying this gene is called this copy is known as and contains the protein building instructions. this copy is sent out into the cytoplasm to the part of the cell known as the the of the ribosome will join together to form a functional ribosome when they attach to the mrna. as the mrna moves through the ribosome, the message is read by transfer rna brings the correct back to the ribosome. the amino acids are placed in the correct order and are hitched together by
