Describe the two types of root systems. compare and contrast

Types of Roots : Roots are of two types viz. (a) Tap roots(normal or main) and

(b) Adventitious roots.

(a) TAP ROOT-Here the radicle prolongs directly to form a main primary roots when the primary root becomes stronger and persistent, it forms the tap root e.g. roots of dicotyledonous plants.

Primary root forms tap root, its lateral branches are secondary roots; branches of secondary roots in turn produce tertiary roots and so on. The tap root with its branches forms the tap root system.

the correct option is option d

the answer would be 2, if crossing over doesn’t occur 2 out of 4 of the daughter cells will have that allele.

hope this : )
