Approximately how many chloroplasts were present in each elodea cell

Mature elodea leaves has the average of 35 chloroplasts in each cell while young elodea leaf has the average of 25 chloroplasts in each cell.

Elodea cell is a plant cell that has many organelles such as a nucleus, many chloroplasts, a hard cell wall, a thin and transparent cell membrane, cytoplasm, and a central vacuole. The number of chloroplasts present in each elodea cell is determined by some factors such as the age of the leaves and the presence of any plant growth stimulants. Mature elodea leaves have the tendency to have more chloroplasts than young elodea leaves. Mature elodea leaves has the average of 35 chloroplasts in each cell while young elodea leaf has the average of 25 chloroplasts in each cell.
