What is vegetative reproduction? Explain with an example. |
| Answer» <p>Vegetative reproduction is any form of asexual reproduction occurring in plants in which a new plant grows from a fragment of the parent plant or grows from a specialized reproductive structure. Plant Propagation is the process of plant reproduction of a species or cultivar, and it can be sexual or asexual.</p> <p>in 1 or 2 sentences</p> | |

| 4514. |
In vegetative reproduction plants take less time to grow and bear flowers and fruits, than plants produced from seeds. why |
| Answer» <p>In vegetative reproduction plants bypass the immature seedling phase and therefore reach the mature phase sooner. This can save a lot of time and money for commercial plant production. For example, it takes 3–4 years for a tea plant to grow big enough (from a cutting) to be ready for harvesting and processing into tea. Growing from seed would take even longer.</p> | |

| Answer» <p>When a candle burns, both physical & chemical changes occur.Physical Changes in Burning Candle: On heating, candle wax melts and form liquid wax. It is a physical change. Since it again turns into solid wax on cooling. This is a reversible change.Chemical Changes in Burning Candle:When you light the candle, the wax present near the wick will melt. Wick absorbs the liquid wax. The liquid wax vaporizes due the heat produced by the flame. This wax vapor near to flameburns and gives new substances like Carbon Dioxide, Carbon soot, water vapours, heat and light. This is an irreversible change.</p> | |
