Question

Two Mark Questions
Write the modes of asexual reproduction in the following organisms; Bryophyllum, Potato, Yeast, Rhizopus, Penicillium

Answer 1

• Bryophyllum reproduce by asexual reproduction, which is vegetative propagation through leaves. In this type, the margin of the leaves develop buds. These buds then develop into mature individuals.
• Potatoes reproduces by natural vegetative propagation through stems. They are underground shoot modifications. Potatoes develop eyes on them that form a whole new plant.
• Yeast develop by budding. Yeasts develop minute little out growths over them. These are in the form of buds. These buds first increase in size and mature. After attaining maturity, they separate from the parent individual and develop into fully blown new individuals.
• Rhizopus is a bread fungus. It exhibits saprophytic mode of nutrition. They reproduce by vegetative propagation through spores. These spores develop into sporangium that give rise to spores by the process of cell division through mitosis and meiosis. These spores then disperse and develop into new organisms.
• Penicillium also shows vegetative reproduction through spore formation. these spores develop in the form of conidia. They develop at the tip of the hyphae and form chains or elongations.
