HORTICULTURE

Detailed explanation-1: -Explanation of the correct option: The biggest group of plants is the angiosperm. An ovary produces seeds, which later become the fruit. These are highly developed plant species.

Detailed explanation-2: -Seeds are surrounded by one or two integuments, which develop into a seed coat that is usually hard. They are enclosed in the ovary of a carpel and thus are protected from the elements and predators. The ovule is attached to the ovary wall until maturity by a short stalk called the funiculus.

Detailed explanation-3: -Unlike gymnosperms such as conifers and cycads, angiosperm’s seeds are found in a flower. Angiosperm eggs are fertilized and develop into a seed in an ovary that is usually in a flower. The flowers of angiosperms have male or female reproductive organs.

Detailed explanation-4: -The term “angiosperm” is derived from the Greek words (’container, vessel’) and (’seed’), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13, 000 known genera and 300, 000 known species.
