A teacher described the structure and function of an organelle as follows:

This organelle is small and formed by the Golgi apparatus. It contains digestive enzymes that are responsible for splitting complex chemical compounds into simpler ones, such as when proteins are broken down into amino acids. Sometimes these organelles may destroy old or damaged cells.

Identify the type of organelle described by the teacher.

• Golgi body

• Lysosome

• Vacuole

• Centriole

Which of the following statements about the nucleus is incorrect?

• The nucleus is surrounded by a double nuclear membrane that contains many pores.

• The nucleus stores the information needed to control all cell activities.

• The nucleus is responsible for the processing, sorting and packaging of cell products.

• The nucleus contains the nucleolus which is responsible for producing ribosomes.

Organelles such as the endoplasmic reticulum, mitochondria, Golgi body, chloroplasts are similar in that their structure is made up of flat membranes containing many folds.

The main reason that they all contain these flat, folded structures is that:

• this provides the organelles with a distinctive pattern for identification.

• this increases the surface area available for the organelle to carry out its function.

• all of these organelles carry out the same function.

• it allows the substances within the organelle to move more freely.
