Answer 1

$\LARGE{ \underline{\underline{ \sf{Required \: answer:}}}}$

We have to pick the odd one out and give the appropriate reason for that:

1) Stigma, Ovule, Petiole, Style, Ovary

• The odd one out is Petiole

All others are the parts of the carpel or the gynaecium which is the female reproductive organ of the plant. The ovule is the female gamete which contains the female nuclei inside the ovary. Petiole is the stalk with which the flower is attached.

2) Potato, Radish, Onion, Ginger, Corm

• The odd one out is Radish

Rest all are underground or modified stems which stores the extra food made by the plant. Radish is a underground root which is actually the tap root.

Answer 2

1) stigma, ovule , Petiole , style, ovary

The odd one is " Petiole ".

Reason ;

The petiole is the stalk that supports a leaf in a plant and attaches it to the stem. Many people often call it a stem, which is incorrect. A stem is the part of the plant that serves as the main source of support and produces nodes and roots, and that's not what we observe in petioles.

2) potato , radish , onion, ginger , corn

.

The odd one is " Radish "

Reason;

Figuring out why radish plants only grow tops can be very frustrating. In new beds, it is often because you didn't loosen soil deeply enough. As a root crop, radishes depend upon loose soil to expand and develop thick roots into bulbs. Excess nitrogen in soil and neutral acidity will also slow the forming of radishes.
