Document Summary
Pellicle: skeletal structure consisting of plasma membrane and underlying cytoskeleton. Euglenoid motion : curious motion that involves changing in the pellicle and shape of the cell. Metaboly: the irregular changes in cell shape are referred to as this. (cytoplasm moves to change the shape) Phototaxic: therefore orients light using stigma which contains pigments that give it its red orange colour. Contractile vesicle: small and inconspicuous, located to ones side of reservoir. Function is osmoregulatory, ridding the cells of excess water. Pyrenoids: associated with chloroplasts and stored as granules in cytoplasm. Pyrenoid: seen as pale circles with darker centers. Cellulose capsule: body is enclosed in this clear cellulose capsule. Isogametes: produced by miotic division in sexual reproduction. Cystoplasmic strands: the way the cells are interconnected and therefore form a hollow colony filled with gelatinous material. Several cells at posterior end of the parent colony (gonidia) move to the center to undergo fission to form plakea.
