M. Hiraoka et al., PIGMENT CONTENT OF THE REPRODUCTIVE CELLS OF ULVA-PERTUSA (ULVALES, ULVOPHYCEAE) - EVIDENCE OF ANISOGAMY, Phycologia, 37(3), 1998, pp. 222-226
The main pigments of three types of reproductive cells (viz. male and
female gametes and zoospores) and the vegetative cells of Ulva pertusa
Kjellman were investigated. The relative amounts of both chlorophyll
a and chlorophyll b in male gametes, female gametes, and zoospores wer
e 1 : 2: 16-18, respectively. The reproductive cells contained gamma-c
arotene, which was not found in the vegetative cells. The carotene con
tent of the male gametes was almost the same as that of female gametes
. Because the difference of the chlorophyll content between male and f
emale gametes is obvious, it is suggested that U. pertusa has anisogam
ous union of gametes.
