cell wall is only found in plant cell . it is absent In animal cell . the neucleus in the plant cell contain a pigments haemoglobin, which contain genetic information to the cell .
D= m/v
solve this formula to find v
by solving we get,
v = m/D
v = 13/19.3
v = 0.67 cm^3
Answer:
It is made up of protons and neutrons
