Chloroplasts:
I. have their own DNA and make all proteins needed by them
II. have a uniparental inheritance
III. cannot be made by the plant cell
1. Only I and II are correct
2. Only I and III are correct
3. Only II and III are correct
4. I, II and III are correct

The pH of the space of thylakoid of isolated chloroplast is decreased and then transferred in the dark to a pH-8 solution. The result would most likely be:
I. The isolated chloroplasts will make ATP.
II. The Calvin cycle will be activated.
III. Cyclic photophosphorylation will occur.
1. Only I
2. Only I and II
3. Only I and III
4. Only II and III

The following diagram shows bundle sheath cells with “special” types of chloroplasts. What is special about them?
  
1. They are larger than normal size
2. They are agranal
3. They are dimorphic
4. Calvin cycle cannot take place in them
