The last common ancestor of gymnosperms and angiosperms possessed the same characters such as pollen, seeds, and vascular tissue.
<h3>What are angiosperms and gymnosperms?</h3>
The gymnosperms are a group of plant that are known as seed- producing plants such as Ginkgo, gnetophytes, cycads etc.
Angiosperms are the plant that produces flowers and having seeds enclosed within their fruit.
Gymnosperms have no production of flowers and fruits and they contain seeds without cover on the surface of their leaves.

Explanation: I found this answer on quizlet
<span>Nickel and cobalt are ferromagnets. This means that they are able to acquire magnetism from induction by an external magnetic field. This is caused by the realignment of atoms and unpaired electrons in their structure induced by the magnetic field. Aluminum and copper don't get magnetized because they have few unpaired electrons in their atomic structures. </span>
