PROKARYOTIC AND EUKARYOTIC CELLS:

We have studied prokaryotic cells so far. The difference between prokaryotic and eukaryotic cells can be seen below:

BASIS PROKARYOTIC CELLS EUKARYOTIC CELLS
NUCLEAR ENVELOPE ABSENT PRESENT
MITOCHONDRIA ABSENT PRESENT
ER, LYSOSOMES, PEROXISOMES ABSENT PRESENT
CHROMOSOMES CIRCULAR, SINGLE, WITH NUCLEOSOMES LINEAR, MULTIPLE, WITH WOUND ON NUCLEOSOMES
RIBOSOMES RELATIVELY SMALL RELATIVELY LARGE

MICROTUBULES

 ABSENT PRESENT
 
 

 

CELL DIVISION

Cell division is a process by which new cells are formed from pre-existing ones. Cells divide by two processes- mitosis and meiosis. Let us look at the difference between them.

NOTE: Chromosomes occupy a central stage in cell division.
