What makes gymnosperms distinct from other groups?
In contrast to flowering plants (or angiosperms), the seeds of gymnosperms grow on the surface of scales or leaves, not enclosed within an ovary (which usually develops into fruits), and are therefore called “naked seeds”.

What makes gymnosperms distinct from other plants?
gymnosperm, any vascular plant that reproduces by means of an exposed seed, or ovule—unlike angiosperms, or flowering plants, whose seeds are enclosed by mature ovaries, or fruits. The seeds of many gymnosperms (literally, “naked seeds”) are borne in cones and are not visible until maturity.
What are the major characteristics of gymnosperms?
General characteristics of Gymnosperms
- Most plants are perennial and woody.
- They are xerophytic, with sunken stomata and thick cuticle.
- The xylem is without vessels and phloem lacks companion cells.
- Reproductive organs are usually in the form of cones or strobili. ...
- Microsporophylls bear microsporangia.
What are major characteristics of angiosperms?
Characteristics of angiosperms
- Habit. The plant body is divided into roots, stems and leaves in angiosperms. ...
- Vascular. They possess vascular tissues like xylem and phloem. ...
- Seed-bearing. ...
- Fruit-bearing. ...
- Flower-bearing. ...
- Formation of male gametophyte. ...
- Formation of female gametophyte. ...
- Embryo sac.
Which one of the following is the most important character of Gymnosperm?
Gymnosperm plants have naked seeds, which means that their seeds are not covered within a fruit. The plant body consists of intermediate to tall shrubs and trees.
What makes gymnosperms unique?
Characteristics of Gymnosperms
They do not produce flowers. Seeds are not formed inside a fruit. They are naked. They are found in colder regions where snowfall occurs.
What advantages do gymnosperms have?
Gymnosperms possess several key evolutionary innovations compared to earlier groups such as the clubmosses and ferns. They produce sperm-containing pollen, which is carried through the air by the wind to the female. This innovation has freed these plants from the need for water for sexual reproduction.
What is the advantage of the Gymnosperm leaf type?
The leaves in gymnosperms are well adapted to withstand extremes of temperature, humidity, and wind. In conifers, the needle-like leaves reduce the surface area. Their thick cuticle and sunken stomata also help to reduce water loss.
What makes angiosperms unique?
Angiosperms are the only plants that have concealed seeds. The seeds in angiosperms are found inside the fruit. The fruit protects the seed and also gives nutrition. No other division in the plant kingdom bears fruits.
What made angiosperms so successful?
Angiosperm success is a result of two novel structures that ensure reproductive success: flowers and fruit. Flowers allowed plants to form cooperative evolutionary relationships with animals, in particular insects, to disperse their pollen to female gametophytes in a highly targeted way.Sep 22, 2021
