Cells Homework 1. Name................................................................................... Below is a drawing of an animal cell as seen under an electron microscope. E D A B C Complete the following table by: • identifying the parts of the cell A to E • naming the part of the cell responsible for the function stated. The first one has been done for you. function controls activities of the cell part of cell label nucleus A carries out aerobic respiration attaches to mRNA in protein synthesis produces secretory vesicles contains digestive enzymes [Total 8 marks] Whitehaven School 1 2.

The diagram below is an electron micrograph of part of a cell from a human liver. This cell is responsible for converting glucose in the body into glycogen for storage. The glycogen can be seen as granules in the cytoplasm. nucleus X glycogen granule (i) Identify the organelle labelled X in the diagram above. .........................................................................................................................
