A gardener wants to grow potato plants. He had put a potato with buds (eyes) in the soil. He succeeded to get a new potato plant because:
potatoes can be grown by root cuttings
there was no animal to eat the potato buds
vegetative propagation is by buds (eyes)
there are no other plant species in that area
vegetative propagation is by buds (eyes)
Potato tubers are modified underground stems that possess nodes known as 'eyes' or buds. When planted in soil, these buds undergo vegetative propagation to give rise to new leafy shoots and root systems.
Potato tubers are modified underground stems that possess nodes known as 'eyes' or buds. When planted in soil, these buds undergo vegetative propagation to give rise to new leafy shoots and root systems.
Think of potato 'eyes' as built-in starter kits on a plant; just like seeds, they carry all the biological instructions needed to grow a brand new plant when given soil and moisture.
STEM: Shoots Today, Eyes Multiply (potatoes propagate vegetative shoots through stem eyes, not roots)
Vegetative propagation is a form of asexual reproduction where new plants grow from vegetative structures such as stems, roots, or leaves rather than seeds. In potatoes, the buds (eyes) located on the tuber stem contain meristematic tissue capable of active cell division and differentiation into a complete new plant organism.
A potato is a modified underground stem (tuber), not a root.
The 'eyes' of a potato are nodes containing axillary buds.
Vegetative propagation allows exact genetic clones of the parent plant to be produced efficiently.
Fast and reliable method of plant reproduction.
Produces genetically identical plants (clones) preserving desirable traits.
Lacks genetic variation, making crops susceptible to the same diseases.
Over-reliance can lead to crop vulnerability (e.g., historical blight epidemics).
Commercial potato farming using seed tubers.
Vegetative reproduction in other crops like sugarcane (stem cuttings) and Bryophyllum (leaf buds).
Option A is incorrect because potatoes are stem tubers, not root cuttings.
Option B is incorrect because animal presence is not the biological reason for plant growth.
Option D is incorrect because plant growth depends on internal meristematic tissue and suitable conditions, not the total absence of other plant species.
C is correct тАФ Potato plants reproduce naturally through vegetative propagation via axillary buds (eyes) located on the stem tuber.
Always remember for Indian competitive exams that a potato is a modified stem (tuber), whereas sweet potato and carrot are modified roots; this distinction is frequently tested in biology sections.
