BIO FALL FINAL - CELLS

If the lysosome were a part of the city it would be the:

• Mayor - controls the cell

• Waste management - digests cell waste and cleans up

• Farms- synthesizes proteins

• Water tower - stores water

cells

Which cell structure is correctly matched with its function?

• vacuole: stores material in the cell

• cell membrane: divides the cell into two halves

• lysosome: manufactures proteins

• ribosomes: packages and modifies proteins

• cell wall and chloroplast

• cell wall and cell membrane

• cell membrane and mitochondria

Which are examples of active transport across the cell membrane?

• 1. osmosis and diffusion

• 1. diffusion and facilitated diffusion

• 1. osmosis and chemiosmosis

• 1. endocytosis and exocytosis

Wes places red blood cells in a petri dish with pure water and observes them under a microscope. He drew a model to illustrate his observations. What is the most likely explanation for Wes's observations?

• 1. The red blood cells were placed into an isotonic solution. Water moved into and out of the cells to maintain homeostasis.

• 1. The red blood cells were placed into an isotonic solution. Water moved into the cells until the cells burst.

• 1. The red blood cells were placed in a hypertonic solution. Water moved from the inside of the cells to the outside of the cells to maintain homeostasis.

• 1. The red blood cells were placed in a hypotonic solution. Water moved from the outside of the cells to the inside of the cells until the cells burst.

All cells contain cell membranes. Which of the following describes the composition of cell membranes?

• 1. Cell membranes are composed of carbohydrate chains, which allow all materials to enter and leave the cell.

• 1. Cell membranes are composed of cellulose, which provide rigidity for the cell.

• 1. Cell membranes are composed of cytoplasm, which allows proteins to be excreted by the cell.

• 1. Cell membranes are composed of lipid molecules, which provide a flexible structure.

Which describes active transport, but not passive transport?

• 1. requires cellular energy

• 1. moves particles across the cell membrane

• 1. moves particles from high concentration to low concentration

• 1. particles diffuse directly through the lipid bilayer
