worksheet 10.2:

Growing plants from parts of a parent plant

Most flowering plants reproduce themselves by producing seeds. The seeds grow into new plants. Seed production involves sexual reproduction since seeds only form after the fertilisation of an egg, Some plants can also reproduce from special types of stems or roots. This is called vegetative or asexual reproduction. In this worksheet you will learn about some of the methods of vegetative reproduction of plants.

Bulbs

Bulbs are plants that grow leaves and then produce flowers during their growing season. The leaves die down at the end of the growing season and the bulb remains in the soil until the next growing season. They also produce new bulbs around or inside the older bulb. Examples of bulbs are plants in the onion family (onion, garlic, chives, shallots) and plants grown for their beautiful flowers such as lily, hyacinth, iris, daffodil and tulip.

Tubers

Tubers are storage stems or roots. Sweet potatoes are an example of a storage root and potatoes are an example of a storage stem. Plants that produce tubers store food to be able to grow again at the start of the next growing season. You can use the tubers to grow new plants.
