Vegetative Propagation
Vegetative Propagation is growing a new plant from a cut piece of a parent plant, not from a seed.
A cutting from a plant works like a slice of potato left in a bowl of water. The slice already has everything it needs to sprout roots and shoots. One parent piece becomes a whole new plant, with no seed involved.
Explaining vegetative propagation by grade level
You can cut a stem from a geranium plant. Put the stem in soil. Roots grow from the cut end. Now you have a new plant that matches the first one.
Projects that explore vegetative propagation
This project starts with a simple cut. You snip four healthy stems from a geranium and place them in jars of distilled water, then watch what happens over two to three weeks. Within 10 to 14 days, adventitious roots — roots that sprout from a stem rather than a normal root system — begin to appear on the cut ends. When the roots have grown, you transfer the cuttings to pots with soil, where they develop into plants that look just like the original parent. That is the essence of vegetative propagation: a new plant grown from a cut piece, not from a seed.
You gather cuttings from four plant types and plant them in soil. Growing a new plant from a cutting instead of a seed is vegetative propagation. This project compares whether a greenhouse or the hormone Rootone helps those cuttings root better.
You place a geranium leaf on soil and observe new buds growing from it. That leaf is a cut piece of the parent plant producing new growth without any seed — a clear case of vegetative propagation. This project explores how the hormones auxin and cytokinin influence that bud development.
