Cells Part 1

Which cell structure contains the cell's genetic material and controls many of the cell's activities?

• cell envelope
• cytoplasm
• nucleus
• organelle

the term Hydrophobic describes which part of a phospholipid?

• both heads and tails
• Neither heads nor tails
• Heads
• Tails

The movement of molecules down a concentration (from high to low) gradient through transport proteins in the cell membrane is a type of

• facilitated diffusion
• osmosis
• energy expenditure
• selective transport

By looking at the conditions given, what type of solution is this red blood cell found in?

• Yolotonic
• Hypotonic
• Hypertonic
• Isotonic

Which process is occurring when a vesicle fuses with the cell membrane and releases its contents outside the cell?

• endocytosis
• osmosis
• exocytosis
• phagocytosis

Which phrase best describes passive transport?

• requires an isotonic solution
• requires no energy from the cell
• requires facilitation by enzymes
• requires transport proteins

Looking at the conditions given in the above diagram, what kind of solution is the red blood cell in?

• Hypotonic
• Isotonic
• Hypertonic
• Yolotonic

Cells fall into two broad categories, depending on whether they

• contain genetic material
• have a nucleus
• contain chloroplasts
• have a cell wall

Which phrase best describes rough ER?

• connected to the Golgi Apparatus
• protected by vesicles
• studded with ribosomes
• stored in the central vacuole

Which process requires NO energy from the cell?

• facilitated diffusion
• active transport
• endocytosis
• exocytosis
