Darwin observed an orchid flower with petals arranged in very long, thin tubes, rather than broad and flat, as we might see in other common flowers. What is the advantage to the orchid having an 11-inch-long nectar tube arrangement of the petals? A. The flower can produce nectar more easily spread over a larger area to attract more pollinators. B. The flower can only be pollinated by o specifically adapted pollinator, reducing cross fertzation among orchid species. C. The flower nectar tube can collect more romwater to mainain health of the lower. D. The long tube can trap insects as a source of nutrients.

B. The flower can only be pollinated by a specifically adapted pollinator, reducing cross-fertilization among orchid species.

Explanation:

answer: angiosperms

dicots

angiosperms are highly evolved plants, they produce seeds which are enclosed within in a carple. these are the largest group of plants on earth. they include trees, shrubs, herbs and small flowering plants. angiosperms exhibit a flowering stage in their life cycle. the flower serves the function of reproduction and fruit formation in majority of angiosperms. dicot is the term used to describe flowering plants that have two seed leaves. dicots are plants which develop seeds which split into two parts called cotyledons. each cotyledon contains one embryo.

here, a small purple flower development indicates that the plant belongs to angiosperms and having two embryonic leaves indicates it belongs to dicots.
