How many of the given statements are correct?
A: The eukaryotes include only multicellular organims.
B: Animal cells have centrioles which are absent in almost all plant cells; Spindle formation is seen in animal seen which is absent in all plant cells.
C: The isolated lysosomal vesicles have been found to be very rich in almost all types of oxidative enzymes.
D: Like chloroplasts, the mitochondria are also double membrane bound and easily observed under the microscope as they are large.
E:  In case of acrocentric chromosome the centromere is situated close to its end forming one extremely short and one very long arm, whereas the telocentric chromosome has a terminal centromere.
