Hello,

Following are the important 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.
• They develop needle-like leaves.
• They are perennial or woody, forming trees or bushes.
• They are not differentiated into ovary, style and stigma.
• Since stigma is absent, they are pollinated directly by the wind.
• The male gametophytes produce two gametes, but only one of them is functional.
• They form cones with reproductive structures.
• The seeds contain endosperm that stores food for the growth and development of the plant.
• These plants have vascular tissues which help in the transportation of nutrients and water.
• Xylem does not have vessels, and the phloem has no companion cells and sieve tubes.

hope it helped.
