(3); try using the phrase "AN OX ate the RED CAT"
(anode=oxidation, reduction=cathode)
the cell theory states that all new cells come from other living cells, and it's true for both multicellular as well as unicellular organisms.unicellular organisms reproduce through asexual reproduction,There are different types of reproduction like binary fission, vegetative, budding, fragmentation etc reproduction in unicellular organisms, through that they directly divide into new similar cells.
whiltin multicellular organisms, reproduction takes place through sexual reproduction, where male and female gametes are formed in separate reproductive organs and get transferred to form an embryo.
so in nut cell in unicellular organisms there is no specific organs,that is responsible for reproduction, while in multicellular there coplex reproductive system
