Which statement is true?

• Cells come in different shapes, but are all about the same size—very, very small.

• Cells come in different shapes and sizes.

• Cells all have the same shape, but come in different sizes.

• Cells are all the same shape and size—small and rounded.

______ cells have genetic material that is surrounded by a lining.

• Prokaryotic

• Eukaryotic

The cell theory is the result of the hypothesis and observation of one person.

• True

• False

The cell theory states that cells do not have to come from cells that already exist.

• True

• False

Which correctly describes a difference between prokaryotic and eukaryotic cells?

• Only prokaryotic cells have vacuoles.

• Eukaryotic cells are smaller than prokaryotic cells.

• Prokaryotic cells have many organelles, each with their own specialized functions.

• Only eukaryotic cells have their genetic material surrounded by a lining.

A spore is a small structure, usually a single cell, produced by plants, fungi, and some microorganisms. In the right environment, a single spore can develop into a new, individual organism.

During observations of soil samples, scientists find tiny structures that appear to be spores.

Which experiment could the scientists use that would best determine if these tiny structures are spores?

• Test them for chemicals normally found in living cells.

• Place them in water and see if they change in shape or mass.

• Observe whether they go through the steps of cell division to form new cells.

• Observe whether they are made of atoms by using a high-powered microscope.

Jade places a fresh, thin slice of onion on a microscope slide to look for evidence that an onion is made of cells.

 

What are two observations Jade could make to provide evidence that an onion is made of cells?

• She observes that there are vertical lines dividing the specimen. She also observes that there are organelles floating around.

• She observes that there are specks of dirt from the garden. She also observes that the specimen has green sections.

• She observes cell walls and cell membranes. She also observes that there is a nucleus in each cell.
