Assertion :
Euglena is studied as an animal as well as a plant.
Reason:
Euglena is more an animal than a plant.
The correct option is B Both the assertion and reason are true but the reason is not a correct explanation of the assertion
Euglena is a typical example of mastigophora. It is
phytoflagellate as it possesses both chloroplast and flagella. It is
autotrophic in sunlight, but becomes heterotrophic in dark. Because
of its two fold nutritional abilities, it is usually studied as a
plant as well as an animal. But it is more an animal than plant
because of:
(a) The absence of cellulose cell wall overlying
the
plasma membrane.
(b) Presence of chloroplasts.
(c)
Reserve food is paramount which is not a true starch.
(d)
Response to various stimuli like an animal.
So, the correct answer is 'If both the assertion and reason are true but the reason is not a correct explanation of the assertion'.
