Which of the following statements is the best definition of biogenesis?
a. Nonliving matter gives rise to living organisms.
b. Living cells can only arise from preexisting cells.
c. A vital force is necessary for life.
d. Air is necessary for living organisms.
e. Microorganisms can be generated from nonliving matter.

검증된 단계별 안내

Step 1: Understand the concept of biogenesis in microbiology. Biogenesis is the principle that living organisms arise from preexisting living cells, not from nonliving matter.

Step 2: Review each option carefully to see which one aligns with the definition of biogenesis.

Step 3: Option (a) states that nonliving matter gives rise to living organisms, which describes spontaneous generation, not biogenesis.

Step 4: Option (b) states that living cells can only arise from preexisting cells, which matches the definition of biogenesis.

Step 5: Confirm that other options (c), (d), and (e) do not correctly define biogenesis, as they refer to other concepts like vitalism, the necessity of air, or spontaneous generation.

주요 개념

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

Biogenesis

Biogenesis is the principle that living cells and organisms arise only from preexisting living cells, not from nonliving matter. This concept disproves spontaneous generation and is fundamental to understanding the origin of life in microbiology.

Spontaneous Generation

Spontaneous generation is the outdated belief that living organisms can arise from nonliving matter spontaneously. This idea was refuted by experiments from scientists like Pasteur, establishing that life does not emerge without existing life.

Vitalism

Vitalism is the theory that a 'vital force' or special energy is necessary for life to exist. This concept was historically used to explain life processes but has been replaced by biochemical and cellular explanations in modern biology.
