Q. Which is correct about cell theory in view of current status of our knowledge about cell structure'?
(a) It needs modification due to discovery of subcellular structures like chloroplasts and mitochondria.
(b) Modified cell theory means that all living being are composed of cells capable of reproducing.
(c) Cell theory does not hold good because all living beings (e.g., viruses) do not have cellular organisation.
(d) Cell theory means that all living objects consists of cells whether or not capable of reproducing.

Why is karyotype done at metaphase?
WHAT ARE TRANSOSOMES?
Q. Cell is the fundamental, structural and functional unit of all living organisms because
(1) Unicellular organisms are incapable of
independent existance
(2) The cell is the basic unit of life
(3) Anything less than a complete structure of cell does ensure independent living
(4) Essential life functions can be performed in only multicellular organisms
