Mature cells of several algal species ( Protosiphon bo‐tryoides, Chlorococcum echinozygotum, Asterococcus superbus, Chlamydomonas reinhardtii, Chlorella pyrenoidota ) that will grow in a strontium‐substitution for calcium are larger and more highly vacuolated than control cells in calcium. In logarithmic phase cultures average cell size of cells in strontium‐replacement medium is greater than for control cells in calcium. The water content of strontium‐replacement cells is indicated to be greater than of control cells. Mechanisms whereby water content and cell size differences may become established are discussed.
