Answer:
- The two lines on the outside of the chloroplast indicate a double membrane: True
- The Golgi apparatus is not shown in this cell but this does not mean that this organelle does not occur in the cell: True
- The relative dimensions and placement of the membranes and organelles in this model are exact representations of those structures in a living cell: False
- The large structure in the center is a nucleus: False
- This cell is capable of photosynthesis: True
Explanation:
- Chloroplast, like mitochondra, have double membrane called the chloroplast envelope. Hence the first statement is true.
- Golgi apparatus is found in all plant and animal cell. It is usually located close to endoplasmic reticulum. Hence this statement is true.
- The relative dimensions and placement of the membranes and organelles in this model are not an exact representation of those structures found in living cell. Hence its a false statement.
- The large structure in the centre is vacuole and not nucleus. Hence its a false statement.
- Since its a plant cell so it is capable of photosynthesis. Hence its a true statement
