Read the following statements about embryogenesis and select the incorrect option.
It is the process of development of embryo from zygote
During this process, zygote undergoes cell division and cell differentiation
Cell divisions decrease the number of cells in developing embryo
Cell differentiation helps groups of cells to undergo certain modification to form specialised tissues and organs
Correct answer: (c)
Solution: In unicellular organisms, cell division is the means of reproduction; in multicellular organisms, it is the means of tissue growth and maintenance. Most tissues of the body grow by increasing their cell number, but this growth is highly regulated to maintain a balance between different tissues.
So, the correct option is 'Cell divisions decrease the number of cells in developing embryo'.
