The process by which modified stem or root of a parent plant grows offspring that remain attached is called
A. Fragmentation
B. Vegetative
C. Tuber reproduction
D. Binary fission
B. Vegetative
The correct answer is B. Vegetative.
To arrive at this answer, let's break down the options and explain each one:
A. Fragmentation: Fragmentation is a process in which a parent organism breaks into fragments and each fragment can grow into a new offspring. This process is commonly seen in some microorganisms, fungi, and certain plants, but it does not involve stems or roots remaining attached.
B. Vegetative: Vegetative reproduction is a process in which a modified stem or root of a parent plant grows offspring that remain attached. This process is observed in many plants, where specialized structures like runners, stolons, or rhizomes enable the growth of new plants from a parent plant.
C. Tuber reproduction: Tuber reproduction generally refers to a type of vegetative reproduction. However, tubers are typically underground storage structures such as potato tubers. These structures serve as food reserves and can be used for propagation.
D. Binary fission: Binary fission is a form of asexual reproduction in which a single-celled organism divides into two identical daughter cells. It is a common method of reproduction in certain bacteria and protists, but it is not relevant to the given context of modified stems or roots.
Therefore, the correct answer is B. Vegetative, as it describes the process by which modified stems or roots of a parent plant grow offspring that remain attached.
