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.
Therefore,last common ancestor of gymnosperms and angiosperms possessed the same characters such as pollen, seeds, and vascular tissue.

Answer:
- If it were true, all organisms would be complex and simple organisms would disappear

Explanation:
Lamark's theory of evolution is that changes in the organism's physical form during its lifetime can be passed on to its offspring. In other words, he believed that children can inherit acquired characteristics from their parents.
The classic example is that he believed giraffes evolved long necks because they would stretch upwords to eat leaves from tall trees, elongating their necks, and then would pass on a longer neck to its children. Or in humans, that a body builder would make a muscular child because of their intense training!
There are a few problems with this theory:
- If we believe this theory, organisms would always be getting more and more complex and 'improved', so simple organisms would disappear.
- We know that changes to the DNA influence inherited physical characteristics, not simply continued use
