Answer:
Angiosperms are the flowering plants that are the largest and most diverse groups of plants in the kingdom Plantae.
These plants occupy about 80% of all green plants present on earth.
Angiosperms are found in almost environments ranging from mountains to deep-sea surfaces to deserts.
These are vascular plants that bear seed and flowers. They exist in different forms; herbs, trees, shrubs, etc.
The flower is the reproductive organ of plants which consists of both male and female reproductive parts.
The flowers, after fertilization, mature into fruits. The seeds are formed and are enclosed within the fruits. Based on the number of seed leaves, angiosperms are divided into monocotyledons and dicotyledons.
The cells and tissues in angiosperms are specialized to perform different functions within the plant.
These plants have specialized vascular tissues, xylem, and phloem that help transport water, mineral, and food to a different part of the plant.
Gymnosperms are vascular plants that have exposed or naked seeds that are not even visible until maturity.
The seeds in gymnosperms are mostly observed in the form of cones.

In most gymnosperms, the male pollen cones also called microstrobili, have reduced leaves, called microsporophylls.
The pollen sacs, also termed microsporangia, are formed at the base of the microsporophylls.
The female cones are termed megastrobili that might be present on either the same plant with male cones or on a different plant.
Like microstrobili, megastrobili also have reduced leaves, called megasporophylls that contain megasporangium.
