Plant Study From Home

The plant that I have been given to look after has been growing very well and strongly. the Hypoestes Plant has not died yet and has permanently been in  glass of tap water. over the last few days that I have recorded the leaves of the plant started off red. Over the next few days the bottom leaves were dying while new shoots and leaves were sprouting near the top. All the new leaves were green. No flowers have grown or budded yet. As the number of new shoots grow and increase so do the number of dying leaves increase. it is still growing and receiving lots of water and sunlight. the plant is not directly outside.
