! which three structures are found in drawing 2 of figure 7-11 but not in drawing 1? what are the names of these structures?

The difference between these structures is that figure I is the structure of an animal cell whereas figure II is a plant cell.

Figure II shows three distinct organelles which are absent in the animal cells:

1. Chloroplast- labelled as L which harvest the energy from the sunlight and converts it to chemical energy.

2. Vacuole- labelled as O a large vacuole is present in the plant cell which is usually absent in the animal cell.

3. Cell wall- labelled as J which is an outer covering surrounding the cellular membrane absent in an animal cell.

the real answer is b. scintillation counter
