Biology Study Guide 2

One function of the nucleus is to:

• store genetic information

• produce energy

• enclose the cell

• make proteins

All the following are found in both plant and animal cells, except:

• a cell wall

• a cell membrane

• mitochondria

• the endoplasmic reticulum

The structure that regulates what enters and leaves the cell is called:

• the nucleus

• the cell wall

• the nuclear membrane

• the cell membrane

Which process requires energy?

• Diffusion

• facilitated diffusion

• active transport

• all of the above

The process by which water passes into or out of a cell is called:

• solubility

• osmosis

• selective transport

• endocytosis

Molecules that are too large to be moved through the membrane can be transported into the cell by:

• osmosis

• endocytosis

• lipid carriers

• diffusion

One difference between prokaryotes and eukaryotes is that:

• nucleic acids are found only in prokaryotes, mitochondria are found in larger quantities in eukaryotes

• Golgi vesicles are found only in prokaryotes

• prokaryotes have no nuclear membrane

• prokaryotes have no nuclear membrane

Which of the following is an example of a prokaryotic cell?

• Amoeba

• virus

• bacterium

• liver cell

Which structure is typically largest and most complex?

• prokaryotic cell

• eukaryotic cell

• nucleus

• virus

Eukaryotic cells are found in:

• Viruses

• bacteria

• plants and animals

• all living organisms
