Angiosperms, likewise called flowering plants, have actually seeds that are enclosed in ~ an ovary (usually a fruit), if gymnosperms have actually no flower or fruits, and have unenclosed or “naked” seed on the surface of scale or leaves. Gymnosperm seed are often configured as cones. The features that identify angiosperms indigenous gymnosperms include flowers, fruits, and also endosperm in the seeds.

You are watching: Which of the following is not a gymnosperm?
|Seed-producing non-flowering plants who seeds space unenclosed or “naked.”|
|Enclosed inside an ovary, usually in a fruit.||Bare, no enclosed; uncovered on scales, pipeline or as cones.|
|Seasonal (die during autumn/fall).||Evergreen|
|Present in flowers; have the right to be unisexual or bisexual||Cones; unisexual|
|Flat||scalelike , needle-like|
|Mostly rely on pollinators.||Mostly depend on wind.|

Hundreds of countless years ago, gymnosperms to be the only kind of plant life top top Earth. In between 250 and 200 million years ago, angiosperms started to evolve. Now, angiosperms are more widely distributed and also populous, and can be thought about the leading plant life on the planet. Angiosperms comprise a far much more diverse range of plants, with a range of 250,000 come 400,000 species. Castle inhabit every kind of land and aquatic environment except the most excessive habitats. Angiosperms may be dicots or monocots.
Examples the Angiosperms and Gymnosperms
Examples that angiosperms room monocots like lilies, orchids, agaves (known because that agave nectar) and also grasses; and dicots choose roses, peas, sunflowers, oaks and maples.
Gymnosperm examples include non-flowering evergreen tree such together pine, spruce and also fir.
Apple tree, a flowering, fruit-bearing angiosperm
Everyday flowering garden plants space angiosperms
Gymnosperm types number only in the thousands, through a little an ext than 1,000 extant species. Castle are uncovered in desert to semi-desert habitats.

Since gymnosperms and angiosperms are both vascular plants, they have actually a sporophyte-dominant life-cycle.
Tissue development in angiosperms above the amount and also complexity discovered in gymnosperms. Angiosperms have actually a triploid vascular tissue, flat leaves in many shapes and also hardwood stems. Due to the fact that of the innumerable varieties of the fruit and/or flower-bearing plants, they have actually variegated colors and also shapes the leaves, flowers and fruits.
Gymnosperms space haploid, have actually spiky, needle-like leaves and also are softwood. Gymnosperms are "simpler" anatomically because they perform not bear flower or fruit, and also although of various species, are usually just tall evergreens with brown cones.
More details about the anatomical differences in between angiosperms and also gymnosperms are defined in the adhering to video:
Reproduction in angiosperms deserve to be unisexual or bisexual. The gametes space spread by wind and also by insect and also animal pollinators attractive by your flowers. Flowers often have both female and also male gametes inside them, and also after fertilization, the ovules develop into a fruit.
The gametes the gymnosperms are discovered in cones. Fertilization is defined as single; the pollen seed fall and also germinate straight on the ovules. Pollen spores room spread by wind alone.
Angiosperms provide virtually every plant-based food, and most breed cub feed. Grains, fruit, legumes, nightshades (including potatoes and tomatoes), gourds, and also cabbages room all angiosperms. Various other angiosperms prefer cotton and flax provide document and textiles. The hardwood the angiosperms is supplied to make hardwood floors.

Gymnosperms native the conifer group like pine, spruce, and also fir are generally used for lumber. Other gymnosperms space processed right into other assets like soap, varnish, and also perfumes.
