7th Grade Science Quiz: Life's Basic Structure

Which of these scientists is credited with naming cells?

All living things are made up of [blank_start]cells[blank_end].

[blank_start]Cells[blank_end] are the [blank_start]smallest[blank_end] unit of all living things that can perform functions necessary for life.

Living cells come only from other dead cells.

Which of the following are the three concepts of the cell theory?

This scientist was one of the first people to describe living cells. He was also the first to describe bacteria.

A [blank_start]microscope[blank_end] is an instrument which makes an object appear bigger than it is.

This scientist was born in 1626, settled in Florence and published "Experiments on the Generation of Insects"

This scientist was born 12/21/1773. He discovered the nucleus of the plant cell.

Which of the following are characteristics of any living thing?

These two scientists determined that both plants and animals were made up of cells.

This scientist determined that all cells come from other cells.

[blank_start]Prokaryotic[blank_end] cells are smaller, simpler cells that are older and the first to evolve. [blank_start]Eukaryotic[blank_end] cells are more complex cells that evolve later.

The following are characteristics of prokaryotic cells

Which are the characteristics of eukaryotic cells?

Which of the following are basic cells?

The plant and animal cells are eukaryotic cells because they both have a nucleus which is surrounded by a membrane.

Select which of the following is NOT found in animal cells

A [blank_start]cell membrane[blank_end] is a protective covering that encloses the entire cell. [blank_start]Cytoplasm[blank_end] is the gelatin-like material inside of the cell. A [blank_start]nucleus[blank_end] is a structure enclosed by its own membrane. An [blank_start]organelle[blank_end] is any part of the cell that is enclosed by a membrane.

The cell membrane never surrounds the cytoplasm.

Plant and animal cells have prokaryotic cells.

Which of the following is only found in animal cells, not plant cells?

This is a tough outer covering that lies just outside the cell membrane.

Is this a animal cell or plant cell?

If a microscope has a 10X eyepiece and a 4X objective lens, what would the total magnification be?

The scientific enterprise is organized around several concepts which make up what is called “[blank_start]the nature of science[blank_end]” (NOS). These concepts serve to standardize and guide scientific inquiry around the globe. Understanding the nature of science helps to understand how science applies to our every day lives and promotes scientific literacy.

Select each of the following below that are part of "The Nature of Science"

[blank_start]Theories[blank_end] are generally used to explain complex natural processes not easily measurable. [blank_start]Laws[blank_end] often use mathematical formulas to show relationships and make predictions about the natural world.

What is a single living thing and the highest level of organization is called what?

The result of reproduction is called [blank_start]offspring[blank_end]. Newly reproduced cells resemble their [blank_start]parents[blank_end].

[blank_start]Evolution[blank_end] is when a group of organisms change over a period of time in order to survive changing environments.

[blank_start]Adaptation[blank_end] is the characteristics that help an organism to survive in its environment

A [blank_start]stimulus[blank_end] is a change in the environment. How you react is called a [blank_start]response[blank_end].
