Biology Terms Review Quiz 1

Which of the following are in the correct order?

• organ system, cell, organ, tissue, organism

• cell, organ, tissue, organ system, organism

• cell, tissue, organelle, organ system, organism

• cell, tissue, organ, organ system, organism

Mrs. Whitehead is teaching her biology class about different types of organisms. She explains that some organisms can produce their own food using light or chemical energy. What term describes these organisms?

• Heterotroph

• Autotroph

• Organism

• Prokaryote

Answer explanation

An autotroph is an entity that can produce its own food using light or chemical energy, distinguishing it from heterotrophs that rely on external sources for nutrition.

Mrs. Whitehead is teaching her biology class about different types of entities in the environment. She asks, 'What is the term for a living thing, anything that can carry out life processes independently?'

• Macromolecule

• Biotic factor

• Organism

• Monomer

Which of the following is a characteristic of a prokaryotic cell?

• It has a nucleus.

• It lacks a nucleus.

• It contains multiple chromosomes.

• It is typically larger than a eukaryotic cell.

Answer explanation

Prokaryotic cells lack a nucleus, distinguishing them from eukaryotic cells which have a nucleus.

What term is used to describe non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems?

• Biotic factors

• Autotrophs

• Abiotic factors

• Heterotrophs

Answer explanation

Abiotic factors are the non-living chemical and physical parts of the environment that affect living organisms and ecosystems.

Which of the following best defines a heterotroph?

• An organism that produces its own food.

• An organism that consumes other organisms for food.

• An organism that can perform photosynthesis.

• An organism that lives in extreme environments.

What is a macromolecule?

• A simple molecule that can bind chemically to other molecules.

• A small biological molecule that is the building block of a polymer.

• A large molecule formed by the joining of smaller molecules, usually by a condensation reaction.

• A type of prokaryotic cell.

What is a monomer?

• A large molecule that can be broken down into smaller molecules.

• A molecule that serves as a building block for polymers.

• A type of macromolecule that cannot be broken down.

• A biological molecule that provides energy for organisms.

Mrs. Whitehead's biology class is studying how a polar bear maintains a stable internal temperature despite the freezing Arctic conditions. Which term refers to this process of maintaining a stable internal environment?

• Homeostasis

• Autotrophy

• Heterotrophy

• Macromolecule

During a science fair, Mrs. Whitehead explains the difference between plant cells and bacteria cells. What key feature did she mention distinguishes a plant cell (eukaryotic) from a bacteria cell (prokaryotic)?

• Plant cells are smaller than bacteria cells.

• Plant cells lack a cell membrane.

• Plant cells have a nucleus.

• Plant cells do not have ribosomes.

Answer explanation

Eukaryotic cells have a nucleus, which distinguishes them from prokaryotic cells that lack a nucleus.
