The correct answer is 10 m/s. This is because:
F = ma
45 = 5m
90 = 5m * 2
Therfore a = 10 m/s
From the options given above, the two structures that will provide positive identification of a plant cell under a microscope are CHLOROPLAST AND LARGE CENTRAL VACUOLES.
Plant cells have some cell organelles which is unique to them, these organelles are not found in animal cells. Examples of such organelles are chloroplasts, large central vacuole, cell wall, etc. The chloroplast found in plant cells help the plants to trap energy from the sun during the process of photosynthesis. The large central vacuole found in plants play a critical role in turgor pressure of plants.
