micrometre)
* Nucleus is absent
and known as
nucleoid.
* Nucleus is present
&
with nuclear
membrane.
* Contains single
chromosome.

number of
chromosomes.
* Cell division takes
place by budding or
fission.
*Cell division takes
place by mitosis or
meiosis.
ANIMAL CELL PLANT CELL

size.
* Generally larger
than animal cell.

7. It is a 2-layered envelope which
is porous & semi-permeable .
It is transparent, semifluid, colloidal
ground substance in which chromatin are
present.
It is a darky stained, spherical
structure.
network of long, fine threads
There are 4 components of nucleus :

9. • CELL IS THE STRUCTURAL AND FUNCTIONAL UNIT OF LIFE.
• CELL WAS DISCOVERED BY ROBERT HOOKE IN 1665.
• DIFFERENT CELL ORGANELLES ARE CELL MEMBRANE, CELL WALL, NUCLEUS,
GOLGI APPARATUS, LYSOSOMES, RIBOSOMES, MITOCHONDRIA, PLASTIDS &
VACUOLES.
• NUCLEUS IS THE MOST CONSPICUOUS AND LARGEST ORGANELLE OF A CELL.
• IT WAS DISCOVERED BY ROBERT BROWN IN 1831.
• IT IS ALSO KNOWN AS DIRECTOR OF THE CELL AS IT CONTROLS ALL THE
ACTIVITIES OF THE CELL
• NUCLEUS IS FORMED OF 4 COMPONENTS : NUCLEAR MEMBRANE ,
NUCLEOPLASM, NUCLEOLUS, NUCLEAR CHROMATIN.
