This document describes characteristics of various algal divisions including Chlorophyta, Rhodophyta, Phaeophyta, Cryptophyta, Dinophyta, Euglenophyta, and Haptophyta. It provides details on their nuclei, pigmentation, flagellation, morphology, reproduction, life cycles, chloroplast structures, storage products, cell walls, and other distinguishing features. Examples are given for many algal types along with diagrams of their cells and organelles. Key aspects like ploidy levels, life histories, and reproductive structures are outlined for important brown and red algal orders.
13. Mazzaellasplendens Rhodophyta can only tell if there are cystocarps (2n +n) on the gametophyte (n) otherwise it is a tetrasporophyte (2n) Sporic
14. Sparlingiapertusa Rhodophyta if with bumps then gametophyte (n) with cytocarps (2n+n) otherwise it is the tetrosporophyte (2n) (Swiss cheese algae) Sporic
49. Cell wall always present – made of cellulose, alginic acid and polysaccharides
50.
51. Fucales: Fucusgardneri Ploidy: 2N Life History: gametic meiosis forms gametes which fuse to form a 2N zygote that grows into the adult plant Other: parenchymatousthalli with apical meristems Anatomy: meristoderm, cortex and medulla present - Receptacles (ends of blades) contain pores (small depressions) under which are conceptacles (spaces) within which are oogonia, antheridia or both
53. Fucales: Pelvetiopsislimitata Ploidy: 2N Life History: Gametic meiosis forms gametes which fuse to form a diploid zygote that grows into the adult plant
68. Desmarestiales: Desmarestiaacuelata Ploidy: 2N Life History: SporicHeteromorphic with microscopic filamentous gametophytes Other: trichothallicmeristem (at the base of hair) which produces a pseudoparenchymatousuniaxialthallus ** only pseudoparenchymatous brown
69. Desmarestiales: Desmarestia sp. Ploidy: 2N Life History: SporicHeteromorphic with microscopic filamentous gametophytes Other: trichothallicmeristem (at the base of hair) which produces a pseudoparenchymatousuniaxialthallus ** only pseudoparenchymatous brown
