Cell structure: Practice Questions

In most animal cells, which organelle is responsible for the release of energy during the process of respiration?

Which of the following describes a key structural difference between a prokaryotic bacterial cell and a eukaryotic plant cell regarding their genetic material?

A scientist identifies a specialised cell that produces a high volume of digestive enzymes. Which sub-cellular structure would you expect to be particularly abundant or active in this cell to facilitate enzyme production?

In a typical bacterial cell, which of the following structures would you find containing the genetic material in the absence of a distinct nucleus?

Which part of a eukaryotic cell is responsible for controlling the passage of substances into and out of the cell?

In a bacterial cell, where are the genes that are not found in a distinct nucleus primarily located?

In the provided diagram of two different cells, identify two structures present in Cell A (a plant cell) that are absent in Cell B (an animal cell).

Explain how plasmids are a unique feature of prokaryotic cells like bacteria and how they differ from the primary chromosomal DNA in terms of their structure and function.
(Hint: Consider the location and typical genes carried by these structures.)

(a) Name three organelles that are found in both a typical animal cell and a typical plant cell.
(b) For each organelle named in part (a), describe its primary function within the cell.
(c) Name two structures that are present in plant cells but are absent from animal cells.

Eukaryotic cells, such as those found in plants and animals, have complex internal structures.
(a) Name two structures found in a plant cell that are not found in an animal cell.
(b) Describe the function of the permanent vacuole in a plant cell.
(c) Explain why the nucleus is essential for the function of any eukaryotic cell.
