Which group of plants bear flowers?
-
Pteridophytes
-
Angiosperms
-
Gymnosperms
-
Bryophytes
Angiosperms or flowering plants include all those plants in which seeds are enclosed in the fruits. An ovule is well developed in angiosperms. Thus option B is the correct answer.
Vessels and companion cells are characteristics of
-
Angiosperm
-
Gymnosperm
-
Pteridophyta
-
Fern
A xylem vessel is a characteristic feature of an angiosperm and help in transportation of water. When it comes to transportation of food, it is the phloem that transports food materials from the leaves to the other parts. Sieve tube elements, companion cells, phloem parenchyma are the different components of the phloem. The sieve tube elements are arranged longitudinally with the companion cells and the pressure gradient in them is maintained by the companion cells
So, the correct answer is 'Angiosperm'
Vessels are found in
-
All pteridophyta
-
All angiosperms
-
Some gymnosperms
-
Both (B) and (C)
Vessels are present in most of the angiosperms and also in certain lower plants like Gnetum, Marsilea and Selaginella. Tracheids are found in pteridophytes, most of the gymnosperms and a few angiosperms.
Thus, the correct answer is option D.

-
Dicotyledons
-
Angiosperms
-
Spermatophytes
