The “plantae” Kingdom under Eukarya

The plantae kingdom consists of plant cells, green algae cells, and multi-cellular organisms made from these two types of cells. Plant and green-algae cells are characterized by cell walls made of cellulose, chloroplasts, and large central vacuoles. The chloroplasts are essential for photosynthesis.
