What type of cell contains the most chloroplasts?
Generally, only two groups of organisms contain chloroplasts: plants and cyanobacteria (aka, the blue green algae). Based on volume, plants contain more chloroplasts than cyanobacteria. Based on ecological location, ie., land or aquatic, land plants contain more chloroplasts than aquatic plants, since the former are more active with the available solar energy than the latter. Based on plant tissue types, the chlorenchyma tissues of the plants contain the most number of chloroplasts compared with the epidermis, parenchyma, collenchyma and sclerenchyma tissue. The chlorenchyma tissue is considered the photosynthetic cells of the plants, so it contains the most chloroplasts. The epidermis and the collenchyma tissues may contain few or less chloroplasts compared with the chlorenchyma tissue. Remember, animal cells do not contain chloroplasts.
