Angiosperms vs Gymnosperms – Difference and Comparison
Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. Gymnosperm seeds are often configured as cones. The characteristics that differentiate angiosperms from gymnosperms include flowers, fruits, and endosperm in the seeds.
Hundreds of millions of years ago, gymnosperms were the only kind of plant life on Earth. Between 250 and 200 million years ago, angiosperms started to evolve. Now, angiosperms are more widely distributed and populous, and can be considered the dominant plant life on the planet. Angiosperms comprise a far more diverse range of plants, with a range of 250,000 to 400,000 species. They inhabit every kind of land and aquatic environment except the most extreme habitats. Angiosperms may be dicots or monocots.
Examples of Angiosperms and Gymnosperms
Examples of angiosperms are monocots like lilies, orchids, agaves (known for agave nectar) and grasses; and dicots like roses, peas, sunflowers, oaks and maples.
Gymnosperm examples include non-flowering evergreen trees such as pine, spruce and fir.
Apple tree, a flowering, fruit-bearing angiosperm
Everyday flowering garden plants are angiosperms
Gymnosperm species number only in the thousands, with a little more than 1,000 extant species. They are found in desert to semi-desert habitats.
Pine tree, a gymnosperm with needle-like leaves and a cone
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. Because of the innumerable varieties of the fruit and/or flower-bearing plants, they have variegated colors and shapes of leaves, flowers and fruits.
Gymnosperms are haploid, have spiky, needle-like leaves and are softwood. Gymnosperms are “simpler” anatomically because they do not bear flowers or fruit, and although of different species, are usually only tall evergreens with brown cones.
More details about the anatomical differences between angiosperms and gymnosperms are explained in the following video:
Reproduction in angiosperms can be unisexual or bisexual. The gametes are spread by wind and by insect and animal pollinators attracted by their flowers. Flowers often have both female and male gametes inside them, and after fertilization, the ovules develop into a fruit.
The gametes of gymnosperms are found in cones. Fertilization is described as single; the pollen grains fall and germinate directly on the ovules. Pollen spores are spread by wind alone.
Angiosperms provide virtually all plant-based food, as well as most livestock feed. Grains, fruit, legumes, nightshades (including potatoes and tomatoes), gourds, and cabbages are all angiosperms. Other angiosperms like cotton and flax provide paper and textiles. The hardwood of angiosperms is used to make hardwood floors.
Gymnosperms from the conifer group like pine, spruce, and fir are commonly used for lumber. Other gymnosperms are processed into other products like soap, varnish, and perfumes.
Difference between Angiosperms and Gymnosperms? – BioMadam – As angiosperms and gymnosperms compose the two major families of most of the plants present, it is important The structure of the wood of angiosperms is inhomogeneous and more varied than that of gymnosperms. Similarly, Ginkgo serves as a common ingredient of many of the chines dishes.Like angiosperms, gymnosperms also have vessels and companion cells. The vascular system is common for the both of them, consisting of In angiosperms, the pollen receptive structures are mostly ovules, so they do not have to depend on external agents for pollination; while gymnosperms…What is the Difference between Angiosperm and Gymnosperm? Angiosperms are advanced land plants whereas Gymnosperms are primitive compared to Type of Pollination. In Angiosperm, animal pollination is common. Gymnosperms are mostly wind pollinated. Pollen Structure.
Angiosperms and Gymnosperms – Biology Wise – The gymnosperms, also known as Acrogymnospermae, are a group of seed-producing plants that includes conifers, cycads, Ginkgo, and gnetophytes. The term "gymnosperm" comes from the composite word in Greek: γυμνόσπερμος (γυμνός, gymnos, 'naked' and σπέρμα, sperma, 'seed'…Angiosperms and gymnosperms are both groups of plants. The students come to know about it in different The tissue structure is an important attribute to differentiate between angiosperms and Compared to the gymnosperms, single fertilization is common where only one male gamete actively…Gymnosperms and angiosperms both have ovule whcih is after fertilization becomes seed. The ovule in the gymnosperm is naked and not enclosed in the fruit, whereas in the angiosperms seeds are enclosed in the fruits.
Difference between Angiosperm and Gymnosperm – Angiosperms and gymnosperms are vascular land plants that reproduce by seeds. The angiosperm vs gymnosperm difference comes down to how Gymnosperms and angiosperms are more highly evolved than nonvascular plants. Both are vascular plants with vascular tissue that live on land and…Angiosperms and gymnosperms are both seed-bearing, vascular land plants on earth. Angiosperms are flowering plants with seeds enclosed within an ovary Although both share some common characteristics, there are many differences in their structure, reproduction, and lifecycle.20) Which structure is common to both gymnosperms and angiosperms? 21) Angiosperm double fertilization is so-called because it features the formation of ? One embryo involving one sperm cell and of endosperm involving a second sperm cell.
