[47] The concentration of photosynthetic products are altered by the environmental conditions like change in pH, the salinity of medium, change in light intensity, nutrient limitation etc. Asexual reproduction can occur through the production of spores and by vegetative means (fragmentation, cell division or propagules production). [14] In addition to multicellular brown algae, it is estimated that more than half of all known species of microbial eukaryotes harbor red-alga-derived plastids. carrageenan meaning in Urdu (Pronunciation -تلفظ سنیۓ ) US: 1) carrageenan.
