Homework Answers
Answer- B. Parallel leaf venation.
Explanation- Most of the famous taxonomist while classifying the plants, concluded that monocots are later originated than dicots and the members of magnoliaceae as most primitive angiosperms as the members posses large flower having many petals and spiral arrangment of floral parts which is very much primitive in nature.
So, option A is incorrect.
Pollen with one opening means single aperturate pollen like sulcus pollen grain which posses a furrow like aperture. This is also found in a primitive dicotyledon family Nymphaeaceae.
So, option C is incorrect.
Most of primitive family like Magnoliaceae have large woody tree members like Michelia champaca, Magnolia grandiflora. This is considered as primitive character.
So, option D is incorrect.
Taxonomist Arthur Cronquist while proposed the Integrated system of classification of flowering plants showed that dicots are primitive, from them monocots are originated.
So, option E is incorrect.
As monocots are considered as advanced and they shows parallel venation, it is not the ancestral character.
So, option B is correct
