While walking in the lawns of DLF Capital Greens, New Delhi, we came across two beautiful flowers. We then took a sample of a fresh and an aged flower. Later during our research on them we found that they were West India Jasmine (Plumeria alba ). On observing the fresh and aged variants , the following were our observations and questions : 

1. Observation - The fresh petal looked like a newly whitewashed brick wall with some black lines. We believe these black lines are cell walls.
2. Observation - The petal of the aged flower looked as if the whitewashed wall had got dirty, old and pale with a continuous fashion of yellow coloured stripes .Question - What are these yellow stripes? Are they a result of some sort of fungal infection? 
3. Observation - In the petal of the aged variant there was a stranded green structure which was not visible to the naked eye. Also, nothing of this type was found in the fresh type. Question - What are these green strands? Was it the reason for aging?
4. Observation - The fresh sample had a bluish tint of white color while in the aged sample it seemed to have turned silvery and reddish.
5. Question - Is the change of tint a symbol of aging or some sort of reaction that might have taken place?
