Answer 1

schlieden.

EXCEPTION ARE FOLLOWING.

Viruses do not possess a cellular machinery. They consist of a nucleic acid (DNA & RNA) core surrounded by a protein sheath and are considered to be an organism.
(2) The bodies of certain fungi are made up of protoplasm and nuclei.
(3) RBCs and sieve tube cells continue to live without nucleus and other vital organelles.
(4) Bacteria and blue-green algae do not have an organised nucleus. Their genetic material (DNA) is naked and the cell organelles are absent

Answer 2

The other main exception to cell theory is the special case of viruses. Viruses lack the ability to generate energy on their own, and also generate no waste products, both hallmarks of living organisms. Viruses also lack the ability to replicate without first invading a host cell.
