Did the life form change as the plant matured?

The life form is the appearance of the plant. If we consider almost any plant, then it can change as it grows. Sometimes new shoots just appear, the trunk grows, more leaves appear and the plant itself becomes larger. But some plants can vary a lot over time. For example, wheat. When it sprouts, it looks like grass. After a while, an ear appears. This is a noticeable change. Therefore, we can say that the life form of plants changes with growth.
