Question

Neem is classified under
(a) Thallophyta
(b) Bryophyta
(c) Pteridophyta
(d) Angiosperms

Answer 1

Hint: Flowering plants or phanerogams in which the ovules present inside the gymnosperms and are divided into two types depending on the number of cotyledons present in the seed. They are also called spermatophytes.

Complete answer:
Kingdom Plantae consists of algae, bryophytes, pteridophytes, gymnosperms, and angiosperms. In common, plants are classified as flowering plants and non-flowering plants. Flowering plants are called phanerogams and non-flowering plants are called cryptogams. algae, bryophytes, and pteridophytes come under cryptogams. Angiosperms and gymnosperms come under phanerogams. Azadirachta Indica (neem) belongs to the flowering plants and it contains ovules inside the ovary of gynoecium which is a characteristic feature of angiosperms

Additional Information: - Chlorophyll bearing, simple, thalloid, autotrophic, and largely aquatic organisms are present in the class algae. Archegoniate, embryophyte, and tracheophytes cryptogams are present in the class Bryophyta. Archegoniate, embryophyte, and tracheophyte cryptogams are present in the class Pteridophyta. All of them are non-flowering plants.
- Plants in which the ovules are not enclosed by any ovary wall and remain exposed both before and after fertilization belong to the class gymnosperms. The seed that develops post-fertilization is naked. Gymnosperms are Archegoniate, embryophyte, and tracheophyte phanerogams.
- Plants in angiosperms, the ovule is present inside the ovary of the gynoecium. They are non-archegoniate, embryophyte, vascular, fruit-bearing phanerogams.
- In angiosperms fertilization is termed double fertilization and fertilization is siphonogamous oogamy.
- examples of angiosperms are all the flowering plants without naked ovules.
So, the correct answer is ‘angiosperms’

Note: Gymnosperms and angiosperms are also called spermatophytes which means seed-bearing plants. Based on the number of cotyledons present in the seed, angiosperms are divided into two types namely dicotyledons and monocotyledons. Neem is a monocotyledon because its seed contains only one cotyledon.
