EMBRYOLOGY

CHROMOSOMES AND CELL DIVISIONS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
cell division in eukaryotic cells is a complex process because of
A
the multiple chromosomes
B
the nucleus
C
the many organelles
D
all of the above
Explanation: 

Detailed explanation-1: -Eukaryotic have a more complex cell structure due to compartmentalisation of organelles. So, they need a more complex process like mitosis which also divides the organelles and cytoplasm equally among the daughter cells.

Detailed explanation-2: -Like prokaryotic cells, all eukaryotic cells are surrounded by plasma membranes and contain ribosomes. However, eukaryotic cells are much more complex and contain a nucleus, a variety of cytoplasmic organelles, and a cytoskeleton (Figure 1.7).

Detailed explanation-3: -The division cycle of most cells consists of four coordinated processes: cell growth, DNA replication, distribution of the duplicated chromosomes to daughter cells, and cell division.

Detailed explanation-4: -Cell division is simpler in prokaryotes than eukaryotes because prokaryotic cells themselves are simpler. Prokaryotic cells have a single circular chromosome, no nucleus, and few other organelles. Eukaryotic cells, in contrast, have multiple chromosomes contained within a nucleus, and many other organelles.
