Which of the following is not a characteristic of bacteria?
a. Are prokaryotic
b. Have peptidoglycan cell walls
c. Have the same shape
d. Grow by binary fission
e. Have the ability to move

검증된 단계별 안내

Step 1: Understand the characteristics of bacteria. Bacteria are unicellular prokaryotic organisms, meaning they lack a true nucleus and membrane-bound organelles.

Step 2: Review each option in the question to determine if it correctly describes bacteria:

Step 3: Option a states bacteria are prokaryotic, which is true because bacteria do not have a nucleus.

Step 4: Option b states bacteria have peptidoglycan cell walls, which is true as peptidoglycan is a major component of bacterial cell walls.

Step 5: Option c states bacteria have the same shape, which is incorrect because bacteria exhibit a variety of shapes such as cocci (spherical), bacilli (rod-shaped), and spirilla (spiral-shaped).

주요 개념

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

Prokaryotic Cell Structure

Bacteria are prokaryotes, meaning they lack a nucleus and membrane-bound organelles. Their genetic material is found in a nucleoid region, and their cellular processes occur in the cytoplasm, distinguishing them from eukaryotic cells.

Bacterial Cell Wall Composition

Most bacteria have cell walls made of peptidoglycan, a polymer that provides structural support and shape. This feature is unique to bacteria and helps protect them from environmental stress and osmotic pressure.

Bacterial Morphology and Reproduction

Bacteria exhibit diverse shapes such as rods, spheres, and spirals, so they do not have the same shape. They reproduce asexually through binary fission, a process where one cell divides into two identical daughter cells, and many can move using structures like flagella.
