After mitosis, plant cells may specialize into tissues like xylem, phloem and palisade cells. This allows the plant to
A)divide the work that needs to be done to survive in a manner that is most efficient
B)get nutrients to the parts that need them
C)save DNA by shutting off parts of the nucleus that aren't needed
D)increase the rate of photosynthesis while reducing the rate of cellular respiration
2
A multicellular organism is one that has
A)a single large cell that does multiple tasks
B)many cells which may or may not be specialized
C)many nuclei in each cell
D)a need to ingest organic materials in order to survive
3
In many multicellular organisms
A)every cell is near the surface and can get the nutrients it needs directly from its environment
B)there are many nuclei which are close to the cell's surface so each can get the nutrients it needs easily
C)some cells are not near the surface and must rely on specialized cells to deliver the nutrients they need
D)wastes can diffuse directly into the environment from every cell in the organism
4
If a cell from a freshwater organism is placed in distilled water, the cell will
A)shrink due to the movement of water from the inside of the cell to the outside
B)not change in volume due to the isotonic nature of the distilled water
C)allow glucose to diffuse out of the cell in order to make the water isotonic to the cell
D)swell and burst due to the movement of water from the environment into the cell
5
If a membrane is able to let glucose and water pass through it but not salt, the membrane can be described as
A)permeable
B)impermeable
C)semipermeable
D)depermeable
6
A piece of dialysis tubing is filled with 5% salt solution and placed into a beaker filled with a 7% salt solution. The dialysis tubing is permeable to water but not to salt. You would expect
A)salt to move out of the tubing, and water to move out as well
B)water to move out of the tubing
C)salt to move into the tubing
D)water to move into the tubing
7
An aquatic plant is placed in a 3% solution of glucose. After 24 hours, its mass does not change. We can describe the experiment by saying that the
A)plant and glucose solution are isotonic to each other
B)the plant is isotonic to the water, but the water is not isotonic to the cell
C)the plant is hypotonic to the glucose solution
D)the glucose solution is hypertonic to the plant
8
The gas required for cellular respiration is
A)water
B)carbon dioxide
C)methane
D)oxygen
9
The gas that is a waste material produced by cellular respiration is
A)carbon dioxide
B)oxygen
C)water
D)glucose
10
Cellular respiration is
A)endothermic
B)exothermic
C)neither exo- nor endothermic
D)both exo- and endothermic
