What is the process of vegetative reproduction in plants?
- By Roots
- By Stem
- By Leaves
Vegetative reproduction involves producing new plants from vegetative parts such as roots, stems, and leaves.
Which plants reproduce through swollen roots?
- Sweet potato
- Asparagus
- Dahlia
TUBERS
These roots store food and have buds that can grow into new plants when planted.
What is a potato tuber?
A swollen underground stem modified to store food
Potato tubers have buds or ‘eyes’ that can grow into new plants.
What type of plant structure is an onion bulb?
A modified shoot with thick, succulent leaves
The bulb can produce new bulbs with the help of buds.
What is a rhizome?
An underground stem with scaly leaves, buds, and roots
Examples include ginger and turmeric.
What are corms?
Swollen stems in plants such as Colocasia and Gladiolus
These structures help in vegetative reproduction.
True or false: The onion bulb is a stem modification.
FALSE
The onion bulb is a shoot modification, with the stem represented by a small white discoid portion.
How do leaves contribute to plant reproduction?
In some cases, leaves can produce plantlets from notches on their margins
These plantlets can fall off and grow into new plants.
What is the importance of reproduction in plants?
To maintain the continuity of life
Asexual reproduction occurs through budding, fragmentation, spore formation, and vegetative propagation.
