What plant group has the most species?

Are mosses gymnosperms or angiosperms?

The most common bryophytes are mosses. The pteridophytes include ferns. The gymnosperms include pines and other conifers. The angiosperms are the flowering plants.

Do gymnosperms seed?

Gymnosperms are a smaller, more ancient group, and it consists of plants that produce “naked seeds” (seeds that are not protected by a fruit). There are more than 1,000 species of gymnosperms still found on Earth. The key difference between angiosperms and gymnosperms is how their seeds are developed.

How do you identify a Gymnosperm?

1. They do not have an outer covering or shell around their seeds.
2. They do not produce flowers.
3. They do not produce fruits.
4. They are pollinated by the wind.

• Occurrence:
• Xerophytic Traits:
• Xylem:

How can you tell if it is a cycad and not a palm?

As palms grow, leaves encircle the stem at the base and leave circular scars around the trunk. Alternatively, cycads have two rows of leaves along a stem that uncoil from the trunk. Generally, the trunk of a cycad is stocky, and they also have little or no branching.

Are carrots monocots or dicots?

Which gymnosperms can tolerate air pollution?

Of four gymnosperm species collected from road side, all species (Cedrus deodara, Araucaria bidwillii, Thuja orientiales and Pinus roxburghii) showed high value of APTI (i.e., more than 8), indicating their resistance to air pollution.

What are the advantages and disadvantages of gymnosperms?

Gymnosperms have a disadvantage compared to angiosperms because once gymnosperm seeds fall or are blown out of their cones they only have a thin cover for protection. Many gymnosperms such as coniferous are adapted to thrive in environments with long cold winters and low amounts of nutrients in their soil.

Where do gymnosperms dominant?

They are found throughout much of the earth, but form dominant vegetation in many colder and arctic regions.
