Difference between Angiosperms and Gymnosperms |
Angiosperms are vascular plants with stems, roots, and leaves. The seeds of the angiosperm are found in a flower. These make up the majority of all plants on earth. The seeds develop inside the plant organs and form fruit. Hence, they are also known as flowering plants.
Angiosperms are the most advanced and beneficial group of plants. They can grow in various habitats as trees, herbs, shrubs, and bushes.
The classification of angiosperms is explained below:
The angiosperms originated about 250 million years ago and comprise 80% of earth’s plant life. They are also a major source of food for humans and animals.
Angiosperms and gymnosperms are both seed-bearing plants with a few similarities. This is due to the fact that gymnosperms were present for at least 200 million years before the angiosperms evolved and they may have shared a common ancestor.
The main difference between angiosperms and gymnosperms is their diversity. The diversity of angiosperms is greater than the gymnosperms. The higher diversity indicated the angiosperms adapted to a wide plethora of terrestrial ecosystems. Another characteristic of angiosperms is the flowers and production of fruits.
Following are the important difference between angiosperms and gymnosperms:
The word angiosperm is derived from Greek, which translates to a “container.” As the name suggests, the angiosperms are vascular plants, which bears seeds in fruits or mature ovaries. Angiosperm forms flower that carries reproductive organs and fruits. These plants are more adaptive to the terrestrial habitat and have a very wide distribution, around 250000 species have been identified to date.
Fruits trees including Mango, Apple, Banana, Peach, Cherry, Orange, and Pear often shows flowers before they bear fruits and the pollination process is generally carried out by agents such as bees.
Grains including rice, corn, and wheat are also examples of Angiosperm. In these plants, the pollination process is carried out by the wind. Other examples of Angiosperms include roses, lilies, Broccoli, kale, Petunias, Eggplant, Tomato, Peppers and sugarcanes.
Gymnosperms are other types of plant that bear seeds directly on sporophylls without covering. As the name suggests the gymnosperms are vascular plants of the Kingdom Plantae which bear naked seeds. There are very fewer species of gymnosperms, few examples of these plants are cypress, Gnetum, pine, spruce, redwood, ginkgo, cycads, juniper, fir, and Welwitschia.
The main reason for being very fewer species is the lack of protection of seeds. The seeds are naked and unprotected when released. They need to get into the ground quickly to take root or they will be damaged by animals, weather conditions or any other factors.
