Foundations in Cells and Genetics

During a science class, Isla was fascinated by the structure of a cork under a microscope. Her teacher explained that the scientist who first coined the term "cell" after observing cork was:

• Anton van Leeuwenhoek

• Matthias Schleiden

• Robert Hooke

• Theodor Schwann

During a science class, Mason was fascinated by the story of Anton van Leeuwenhoek. What did Anton van Leeuwenhoek contribute to the development of cell theory?

• He discovered the cell nucleus.

• He observed and described living cells in pond water.

• He proposed that all plants are made of cells.

• He introduced the concept of spontaneous generation.

In a biology class, Nora and Benjamin are discussing the principles of cell theory. Which statement is NOT a part of the modern cell theory?

• All living things are composed of one or more cells.

• Cells are the basic units of structure and function in organisms.

• All cells arise from pre-existing cells.

• Cells can spontaneously generate from non-living matter.

Matthias Schleiden and Theodor Schwann contributed to cell theory by stating that:

• All cells arise from pre-existing cells.

• Cells are the basic unit of life.

• Plants and animals are composed of cells.

• Cells contain a nucleus.

In a biology class, Avery was curious about how new cells are formed. The teacher explained that the principle that all cells come from pre-existing cells was proposed by:

• Rudolf Virchow

• Robert Brown

• Louis Pasteur

• Robert Hooke

During a biology class, Ava is asked to identify which of the following is a characteristic of prokaryotic cells?

• Presence of a nucleus

• Membrane-bound organelles

• Lack of a defined nucleus

• Multicellular organization

During a biology class, Grace and Ethan are learning about cell structures. They discover that eukaryotic cells differ from prokaryotic cells in that eukaryotic cells:

• Are always unicellular

• Lack membrane-bound organelles

• Have a defined nucleus

• Do not contain DNA

During a biology class, Anika was asked: Which of the following organisms is unicellular?

• Human

• Oak tree

• Amoeba

• Mushroom

In a school project, Emma and Kai are studying how living organisms are structured. They learn that multicellular organisms are composed of:

• A single cell

• Multiple cells working together

• Cells without nuclei

• Cells lacking DNA

In a biology class, Jackson and Aria are learning about how different organisms obtain energy. They discover that autotrophic organisms obtain energy by:

• Consuming other organisms

• Performing photosynthesis or chemosynthesis

• Absorbing nutrients from their environment

• Engaging in parasitic relationships
