• The basic structural and functional units of all living organisms are cells.

• The basic structural and functional units of all living organisms are tissues.

• The basic structural and functional units of all living organisms are organs.

• The basic structural and functional units of all living organisms are systems.

Which of the following is a key feature of eukaryotic cells?

• No membrane-bound nucleus

• A cell wall made of peptidoglycan

• A membrane-bound nucleus containing genetic material (DNA)

• No membrane-bound organelles

List two additional structures found in animal cells.

• Mitochondria and Ribosomes

• Chloroplasts and Cell Wall

• Nucleus and Vacuole

• Golgi apparatus and Lysosomes

The main difference between the cell walls of plant cells and prokaryotic cells is:

• Plant cell walls contain cellulose, while prokaryotic cell walls do not.

• Prokaryotic cell walls contain cellulose, while plant cell walls do not.

• Both plant and prokaryotic cell walls contain cellulose.

• Neither plant nor prokaryotic cell walls contain cellulose.
