Identify "A" diagram and select the right option giving some of the features correctly?
(I) | (II) | (III) | |
(a) | A= Paramecium | Saprophytic | Pellicle makes the body flexible |
(b) | A= Euglena | Autotroph & heterotroph | Pigmentsare identical to higher plants |
(c) | A= Euglena | Heterotroph | They have a gullet that opens to the outside of the cell surface |
(d) | A= Trypanosoma | Heterotroph | They have one long flagellum |
Text Solution
Verified by ExpertsB
Paramecium → Incorrect (Paramecium has cilia, not a flagellum)
Euglena — Autotroph & heterotroph — Pigments are identical to higher plants → Correct
Euglena is mixotrophic: it can photosynthesize and also feed heterotrophically. Its pigments include chlorophyll a and b, like higher plants.
Euglena — Heterotroph — They have a gullet... → Partly true about gullet/reservoir, but Euglena is not only heterotroph.
Trypanosoma → Incorrect shape/features for this diagram.
