Multiple nuclear divisions without cytoplasmic divisions result in cells called _________.
a. Mycoses
b. Coenocytes
c. Haustoria
d. A pseudohypha

검증된 단계별 안내

Understand the key terms in the question: 'multiple nuclear divisions without cytoplasmic divisions' means the nucleus divides several times but the cell's cytoplasm does not split, resulting in a multinucleate cell.

Recall that in microbiology, when a cell undergoes nuclear division multiple times without cytokinesis (cytoplasmic division), the resulting structure is called a coenocyte.

Review the options given: a) mycoses are fungal infections, b) coenocytes are multinucleate cells formed by multiple nuclear divisions without cytoplasmic division, c) haustoria are specialized fungal structures for nutrient absorption, and d) pseudohyphae are chains of elongated yeast cells.

Match the definition from the question to the correct term: since the question describes multinucleate cells formed by nuclear division without cytoplasmic division, the correct term is 'coenocytes'.

Conclude that the answer is option b, coenocytes, based on the definition and elimination of other options.

주요 개념

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

Nuclear Division vs. Cytoplasmic Division

Nuclear division (karyokinesis) is the process where the nucleus divides, while cytoplasmic division (cytokinesis) divides the cell's cytoplasm. When nuclear division occurs repeatedly without cytokinesis, it leads to multinucleated cells, which is key to understanding the question.

Coenocytes

Coenocytes are multinucleated cells formed by multiple rounds of nuclear division without cytokinesis. They are common in certain fungi, algae, and protists, where the cytoplasm remains continuous despite multiple nuclei.

Other Cell Structures in Fungi and Microorganisms

Mycoses are fungal infections, haustoria are specialized structures for nutrient absorption in parasitic fungi, and pseudohyphae are chains of elongated yeast cells. Understanding these terms helps differentiate them from coenocytes.
