The correct answer is - A. Photosynthesis.
Through the process of photosynthesis, the plants manage to use the sunlight, and combining it with the nutrients that they have got through their root system, they manage to produce glucose. Then they use the glucose by converting it to energy, which is crucial for their survival and proper growth, especially for their fruits, vegetables, seeds, spores.
This process is only able to occur with enough sunlight at disposal for the plant, and even if there's very small amount of nutrients gathered from the soil or water, the plants are still able to perform this process.
Endocrine glands secrete hornmones whereas
exocrine glands secrete enzymes....
here, Pituitary gland secrete stimulating and growth hormone and thyroid gland secrete thyroxine hormone whereas salivary gland produce enzyme called saliva
So,pituitary gland and thyroid gland are endocrine and salivary glands are exocrine...
HOPE THIS HELPS YOU!!!!!
