Groups of Protists – Biology - University of Hawaiʻi The red algae life cycle is an alternation of generations. Some species of red algae contain phycoerythrins, photosynthetic accessory pigments that are red in color and outcompete the green tint of chlorophyll, making these species appear as varying shades of red. Other protists classified as red algae lack phycoerythrins and are parasites. Red algae are common in …

GRADE 12 LIFE SCIENCES LEARNER NOTES - Mail & Guardian Alternation of generations: is the alternating of a haploid with a diploid phase. Each phase has one distinct structure: a gametophyte that is haploid, and a sporophyte that is diploid. A haploid plant of a gametophyte generation will produce gametes by the process of mitosis. Alternation of generations - Wikipedia The diagram shows the alternation of generations in a species which is heteromorphic, sporophytic, oogametic, dioicous, heterosporic and dioecious. A seed plant example might be a willow tree (most species of the genus Salix are dioecious). Starting in the centre of the diagram, the processes involved are: An immobile egg, contained in the archegonium, fuses with a … Sessility (botany) - Wikipedia In botany, sessility (meaning "sitting", used in the sense of "resting on the surface") is a characteristic of plant parts (such as flowers and leaves) that have no stalk.
