Characteristics of Angiosperm
- Angiosperms may be found in a wide variety of environments, including those with fresh water, desert, extremely cold arctic climates, and extremely hot tropical climates.
- Stems, roots, and leaves are the 3 different parts of the sporophyte.
- Angiosperms are vascular plants and possess xylem and phloem.
- Angiosperm are heterosporous and produce microspores and megaspores.
- They produce seeds that are enclosed or covered by an ovary.
- They possess true leaves, true stems and true roots.
- When angiosperm becomes mature, the ovary constitutes the fruit.
- In angiosperms, fertilization occurs more quickly. Because the female reproductive components of the smaller females generate seeds more quickly.
- Stamens, the reproductive organs of flowers, are a component of all angiosperms. They create the pollen grains that contain the genetic material.
- One of the main benefits of angiosperms is the formation of endosperm. After fertilization, the endosperm develops and serves as a food supply for the growing seed and seedling.
Characteristics of Gymnosperm
- Gymnosperm plants have naked seeds, which implies that they do not have fruit coverings over them.
- Gymnosperms do not vegetatively reproduce by cutting, budding, etc.
- Heterosporous spores are seen in gymnosperms.
- Microspores and megaspores are two types of spores that gymnosperm generate.
- They are xerophytic and terrestrial but never aquatic.
- The leaves of gymnosperm are needle-like that have tough cuticles and sunken stomata.
- Gymnosperm doesn’t take place in double fertilization.
- They are heterosporous plants that produce a variety of spores.
- Gymnosperms are wind pollinated.
- The plant body of gymnosperm consists of intermediate to tall shrubs and trees.
Difference between Angiosperm and Gymnosperm
|Seeds||Their seeds are often contained in an ovary that is found in a fruit.||Their seeds, which are located on scales, |
leaves, or as cones, are exposed and unenclosed.
|Reproduction||The spread of reproduction is dependent on the animals.||The spread of reproduction is dependent on the wind.|
|Lifecycle||The lifecycle of angiosperm are seasonal.||The gymnosperm plant is evergreen.|
|Tissues||Angiosperm have triploid tissue.||Gymnosperm have haploid tissue.|
|Leaves||Leaves of angiosperm are flat in shape.||Leaves of gymnosperm are scalelike and needle-like in shape.|
|Wood||Hardwood types||Softwood types|
|Uses||Used for Medications, food, clothing, etc.||Used for Paper, Lumber, etc.|
|Polyembryony||Polyembryony is uncommon.||Polyembryony is common.|
|Archegonia||Archegonia are absent.||Archegonia are present (except Gnetum).|
|Vegetative reproduction||Vegetative reproduction is common.||Vegetative reproduction is very rare.|
