Task 3 Distinguishing Types of Cells (corrected)

What is the smallest unit that can be considered "alive"?

• An atom

• A molecule

• A cell

• An organism

Which of the following domains of life consists of single-celled organisms without organelles that are typically found in extreme environments such as hot mineral springs or deep sea thermal vents?

• Bacteria

• Eukaryote

• Archaea

• Plantae

What characteristic distinguishes Eukaryotes from other domains of life?

• They are single-celled organisms without organelles.

• They are found in animal digestive systems.

• They contain organelles.

• They are typically found in extreme environments.

What category do Archaea and Bacteria belong to according to the tutorial?

• Eukaryote

• Prokaryote

• Archaea

• Bacteria

How many domains of life are there in Biology?

• 1

• 2

• 3

• 4

Which of the following domains are classified as prokaryotes?

• Archaea and Bacteria

• Archaea and Eukaryote

• Bacteria and Eukaryote

• Eukaryote only

What is the function of organelles in the cell?

• They provide structural support to the cell.

• They are membrane-encased regions that do specialized work, similar to organs in the human body.

• They are responsible for the movement of the cell.

• They store genetic information outside the nucleus.

What is the role of lysosomes within a cell?

• To produce energy

• To organize cell division

• To digest food absorbed into the cell

• To store nutrients

Why are enzymes within lysosomes concentrated?

• To increase the speed of cell division

• To digest food more efficiently

• To prevent the digestion of the cell itself

• To break down food in the intestine

Where is the DNA or genetic material located in a cell?

• In the mitochondrion

• In the cytoplasm

• In the nucleus

• In the Golgi apparatus
