A strawberry plant mutant that fails to make stolons would suffer from
a. Too little mineral absorption.
b. A tendency to topple over.
c. Too little water absorption.
d. A reduction in asexual reproduction

검증된 단계별 안내

Understand the role of stolons in strawberry plants. Stolons are horizontal stems that grow at or just below the soil surface and are involved in asexual reproduction by producing new plants.
Consider the options given in the problem. Option (A) refers to mineral absorption, which is primarily the function of roots, not stolons.
Option (B) suggests a tendency to topple over. Stolons do not provide structural support to prevent toppling; this is more related to the plant's root system and stem strength.
Option (C) mentions water absorption, which is also a function of roots rather than stolons.
Option (D) refers to a reduction in asexual reproduction. Since stolons are directly involved in producing new plants asexually, a failure to make stolons would indeed lead to a reduction in asexual reproduction.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Stolons

Stolons, also known as runners, are horizontal stems that grow at or just below the soil surface. They are crucial for asexual reproduction in plants like strawberries, allowing them to spread and form new plants. Stolons facilitate the propagation of genetically identical offspring, enhancing the plant's ability to colonize an area.

Asexual Reproduction

Asexual Reproduction

Asexual reproduction is a mode of reproduction that does not involve the fusion of gametes, resulting in offspring that are genetically identical to the parent. In plants, this can occur through mechanisms like stolons, rhizomes, or tubers, enabling rapid population growth and survival in stable environments without the need for pollinators.

Plant Structure and Stability

Plant structure, including roots, stems, and leaves, plays a vital role in stability and nutrient absorption. While stolons primarily aid in reproduction, other structures like roots are responsible for anchoring the plant and absorbing water and minerals. A lack of stolons does not directly affect stability or absorption but limits reproductive spread.
