Answers
Answer:
Angiosperms are a most diversified group of land plants that include 64 orders, 416 families, and approximately 13000 known genera. Mangifera indica is an example of angiosperms.
Explanation:
Complete answer: Angiosperms are those plants which show flowering. Seeds of angiosperms develop in a female reproductive part which is known as the ovary, which usually ripens to form a protective fruit. Whereas, gymnosperms are plants that do not show flowering and do not have ovaries. Seeds of gymnosperms mature inside the cone. Wind, water or animals carry away seeds from the parent plant. Mangoes are monoecious plants, i.e. they show male and female reproductive organs in the same plant. So, they are self-pollinating and have a dicot seed. Mango is an angiosperm. Some gymnosperms are Cycas, Ginkgo and Pinus, etc.
a) Cycas revoluta belongs to the family of Cycadaceae. It also shows both female and male reproductive parts. Here, pollination occurs through wind and as a result of which, fertilization occurs.
