1)
Plant and animal cells differ in a variety of ways. Notice when you compare the model cells, plant cells contain chloroplasts and animal cells do not. What is the function of this organelle found in plant cells?
A) It is the site of photosynthesis, where glucose is produced.
B) It is the site of cellular respiration, where cellular energy is produced.
C) It is the site of cellular digestion; glucose is broken down to produce energy.
D) It is the site of protein synthesis; amino acids are joined together to make proteins.
2)
Sometimes when plants are under water stress, they wilt. Animals do not wilt! Review the plant cell structure. What analogy based on the plant cell structure explains wilting?
A) The chloroplast is like a factory. When the plant is water-stressed, the chloroplast stops producing energy and the plant wilts.
B) The cell wall is like a cardboard box. When the plant is water-stressed, the cell wall folds, like someone crushing the cardboard box.
C) The large vacuole is like a water-filled balloon. When the plant is water-stressed, the water leaves the vacuole and the cells shrink.
D) The plasma membrane is like the drain in your sink. When the plant is water-stressed, the plasma membrane stops water from going into and out of the cell.
