All living organisms on Earth are divided in pieces called cells. There are smaller pieces to cells that include proteins and organelles. There are also larger pieces called tissues and systems. Cells are small compartments that hold all of the biological equipment necessary to keep an organism alive and successful on Earth.

6. MULTICELLUAR

10. CYTOPLASM :- The portion of the protoplasm
lying inner to the cell membrane, but outside
the nuclear membrane, is called Cytoplasm.
NUCLEUS:- It is the most important part of the
cell. It lies in the centre of the cell, but it may
also occupy peripheral positions. It
controls all the activities of the cell.

11. CELL ORGANELLES

12. • MITOCHONDRIA :- They are present in a large
number in cells engaged in different physiological
activities. They are responsible for cellular respiration
and generating energy for different activities of life.
Hence, they are also called the power house of the
cell.

13. ENDOPLASMIC RECTICULUM (ER) :-
It is a network of membranes. It
provides a skeletal framework to
the cell.
GOLGI COMPLEX :- They stored the material
which are produced by the cell. Hence, they
are also called the power house of the cell.

14. VACUOLE :- It is generally large in plant cells. It
stores excess of water and waste products. In
Amoeba, food materials are held in food
vacuoles for digestion.
RIBOSOMES :- These are the tiny granules
present in the cytoplasm. They help in
protien synthesis.

15. CILLA AND FLAGELLA :- They help in locomotion
and collection of food. Unicellular organisms
like Paramecium have numerous cilia
while Euglena has a single flagellum
