Question

Roundup Ready soybean has which one of the following features?

• A. Rich vitamin-A
• B. Herbicide tolerant
• C. Male sterility
• D. Bacterial blight

Hint:

"Roundup Ready" = Ready to be sprayed with Roundup (herbicide) without dying.

Answer 1

The Correct Option is B

Step 1: Understand the question.
We need the special feature of Roundup Ready soybean. The name itself is a strong hint, so let us read it carefully.

Step 2: Know what Roundup is.
Roundup is the brand name of a weed killer whose active chemical is glyphosate. Farmers spray it to kill unwanted weeds.

Step 3: Think about the problem with weed killers.
Normally a strong weed killer would harm the crop too. So farmers need a crop that can survive the spray.

Step 4: See what the gene does.
Roundup Ready soybean has been genetically engineered to resist glyphosate. The spray then kills only the weeds and leaves the soybean unharmed.

Step 5: Name the feature.
A crop that can withstand a herbicide is called herbicide tolerant. So this is the feature of Roundup Ready soybean.

Step 6: Match the option.
The correct choice is herbicide tolerant.
\[ \boxed{\text{Herbicide tolerant}} \]
