Since gymnosperms and angiosperms are both vascular plants, they have a sporophyte -dominant life-cycle. Tissue formation in angiosperms exceeds the amount and complexity found in gymnosperms. Angiosperms have a triploid vascular tissue, flat leaves in numerous shapes and hardwood stems.

Angiosperm leaves are seasonal in their life cycle while gymnosperms are generally evergreen. Reproductive Process of Angiosperms The flowers of angiosperms have male and female reproductive parts. Stamens are male sex structures that make pollen on their anthers.

The diploid sporophyte of angiosperms and gymnosperms is the conspicuous and long-lived stage of the life cycle. The sporophytes differentiate specialized reproductive structures called sporangia, which are dedicated to the production of spores. The microsporangium contains microspore mother cells, which divide by meiosis to produce haploid ...

Biologists consider gymnosperms to be the oldest among the plants; they have been around since the Carboniferous period, which is 358.9 ± 0.4 million years ago. Angiosperms, on the other hand, are a younger species that started to evolve around 250 million years ago.

Gymnosperms first appeared on Earth during the Carboniferous period about 359-299 million years ago and they dominated the landscape by the Mesozoic era 251-65.5 million years ago. By the end of the Mesozoic era, angiosperm plants had taken over and they remain the most successful terrestrial plant group.

Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers. Both groups use pollen to facilitate fertilization, though angiosperms have an incredible diversity of pollination strategies that are not found among the gymnosperms.

Angiosperms are plants that produce flowers, which are nothing but the reproductive machinery of the plant. The life cycle of angiosperms begin with pollination and end in the formation of fruits which contains seeds that germinate into new plants which mature till they reach the flowering stage, thereby, completing a full circle.

Gymnosperms encompass a diverse group of non-flowering plants that include conifers, cycads, ginkgoes and gnetophytes. Despite this diversity, there are some common factors in the life cycle of gymnosperms. Primarily, this group of plants produces male and female cones as part of the gymnosperm reproductive cycle but do not produce flowers or ...
