Protesta Flagella Cilia Syngamy Isogamy Anisogamy
Dinoflagellates ' Euglenoid's Protozoans In sexual reproduction two haploid gametes fuse to form a diploid zygote ( Fertilization ) S simplest way of sexual . Fusing gamete are morphological similar but physiologically may be similar / dissimilar Gametes morphologically dissimilar but physiologically they may be smaller ot dissimilar
50
Oogamy Male Female Haplontic life cycle Meiosis Diplotic life cycle Meiosis
Develop form of Anisogamy Gamete z small, motile or immotile Gamete is large and immobile, human n → 2n only zygote tic phase diploid and all remaining phase haploid Zygotic. Meiosis 2 n→n→ 2n. Only gametic phase is haploid and remains phase are diploid Gametic meiosis
51
Dinoflagellates Location Appear colour Nutrition Cell wall Covering called
Dinophyceae _ protests with two flagella Marine surface, photosynthetic Yellow, green, brown, blue or red depending on main pigment present Holophytic, autotrophic Divided in to stiff, plates, made up of cellulose Seen as armoured so they called armoured algae
