Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What might happen if plants could not produce glucose?
A
They would not be green.
B
They could not grow and function.
C
They could not absorb energy from the sun.
D
They would not have leaves.
Explanation: 

Detailed explanation-1: -Also, plants need glucose for respiration. If plants stopped producing glucose, that would threaten their survival. The negative effect is even greater for plants considering that, unlike animals, plants cannot burn other nutrients such as fat for energy.

Detailed explanation-2: -Glucose is used by plants for energy and to make other substances like cellulose and starch. Cellulose is used in building cell walls. Starch is stored in seeds and other plant parts as a food source.

Detailed explanation-3: -If photosynthesis ceased, there would soon be little food or other organic matter on Earth, most organisms would disappear, and Earth’s atmosphere would eventually become nearly devoid of gaseous oxygen.

Detailed explanation-4: -Basically, photosynthesis is the process that provides fuel to plants and that allows plants and even some photosynthetic algae to survive and grow. If photosynthesis came to a sudden ending, most plants would die within a short span of time.

Detailed explanation-5: -Glucose affects plant growth and induces delay in development of juvenile to vegetative phase. Glucose induces the synthesis of chlorophyll, rubisco and various photo-protective pigments. Glucose alleviates harmful effects of abiotic stress by increasing antioxidant and sugar level.
