Real questions that test this

आम्लपर्जन्य, वनस्पतीसाठी हानीकारक आहे कारण Acid rain is harmful to plants because

a)(1) ते अन्नद्रव्य पुरवितात / It gives nutrients

b)(2) अन्नद्रव्य हे पूरक म्हणून टाकतात / Nutrients are added as supplement

c)(3) हे अन्नद्रव्य धुवून काढतात / It washes away the nutrients✓ Correct

d)(4) अन्नद्रव्य तशीच राहतात / Nutrients will remain as they are

Acid rain lowers the pH of the soil and leaches essential nutrients like calcium and magnesium away from the plants, making them weak.

खालीलपैकी मॅक्रोन्युट्रिएंट कोणते आहे ? / Which of the following is a macronutrient ?

a)मॅग्नेशियम / Mg✓ Correct

b)मॉलिब्डेनिअम / Mo

c)बोरॉन / Bo

d)झिंक / Zn

Magnesium (Mg) is a macronutrient required by plants in relatively large amounts for chlorophyll synthesis and enzyme activation.

मॅक्रोलेमेंट्स म्हणजे काय ? What are macroelements ?

1)जे घटक कमी प्रमाणात लागतात / Elements required in small amounts

2)जे घटक सम प्रमाणात लागतात / Elements required in equal amounts

3)जे घटक जास्त प्रमाणात लागतात / Elements required in large amounts✓ Correct

4)वरीलपैकी कोणतेही नाही / None of the above

Macroelements are essential plant nutrients required in relatively large amounts for growth and development, unlike micronutrients.

(a)पोटॅशियम

(b)बोरॉन

(c)क्लोरीन

2)फक्त (a) आणि (b) / Only (a) and (b)

3)फक्त (c) / Only (c)

4)फक्त (d) / Only (d)

Potassium is a macronutrient required in large quantities by plants for various physiological functions like osmoregulation and enzyme activation.
