What is the shape and function of cells? The
shape and function of cells
vary depending on their purpose. For example, pipes are
cylindrical for efficient water conduction, while red blood cells
are concave discs to carry maximum oxygen.
How can cells be categorized?
Cells can be categorized as prokaryotic and eukaryotic based on
the nature of their nucleus.
What are prokaryotic cells?
Prokaryotic cells have a primitive nucleus that is not well-
developed and no membrane separating the chromosome from
the cytoplasm.
What are eukaryotic cells?
Eukaryotic cells have a more advanced nucleus, with the genetic
material separated from the cytoplasm by a membrane.
What is double stranded DNA?
Double stranded DNA is a type of genetic material that can be
either circular or linear.
What is the difference between prokaryotic and eukaryotic genetic
material?
In prokaryotic cells, the genetic material is a double stranded,
circular DNA known as the nucleoid or genophore. In eukaryotic
cells, the genetic material is a double stranded, linear DNA known
as the chromosome. It is enclosed by a nuclear membrane.
What are the main differences between prokaryotic and eukaryotic cells?
Prokaryotes lack membrane-bound organelles like nucleus,
mitochondria, and chloroplasts. They have non-membrane-bound
organelles like ribosomes and may also have extra chromosomal
