1. Define prokaryotes

Explanation

Prokaryotes are defined by the absence of a membrane-bound nucleus and organelles. Their genetic material is located in a nucleoid region instead of a true nucleus. This structural simplicity allows faster reproduction through binary fission. The lack of compartmentalization distinguishes them from eukaryotes and explains their efficiency in diverse environments, including extreme conditions where complex cellular organization is unnecessary.

2. Define eukaryotes

Explanation

Eukaryotes possess a true nucleus enclosed by a nuclear membrane, allowing regulated gene expression. They also contain membrane-bound organelles such as mitochondria and endoplasmic reticulum, which compartmentalize cellular processes. This organization supports higher complexity, specialization, and multicellularity. The presence of these structures makes eukaryotic cells larger and metabolically more diverse than prokaryotic cells.

Submit

3. To which domain do archaea belong

Explanation

Archaea belong to a separate domain due to their unique genetic, biochemical, and structural traits. Although prokaryotic, their cell walls, membrane lipids, and RNA sequences differ significantly from bacteria. Many archaea thrive in extreme environments, indicating evolutionary adaptations that justify their classification as a distinct domain rather than being grouped with bacteria.

Submit

4. To which domain do true bacteria belong

Explanation

True bacteria, or eubacteria, are classified under Domain Bacteria based on cell wall composition, ribosomal RNA structure, and metabolic traits. Unlike archaea, bacterial cell walls contain peptidoglycan. This distinction is critical in taxonomy and medicine, as it affects antibiotic targeting and ecological classification of microbial life forms.

Submit

5. What shape is a coccus bacterium

Explanation

Coccus refers to bacteria with a spherical shape. This geometry minimizes surface area relative to volume, which can influence nutrient exchange and mobility. Cocci often occur in pairs, chains, or clusters, affecting how they colonize surfaces and host tissues. Shape plays a role in bacterial identification and pathogenic behavior.

Submit

6. What shape is a bacillus bacterium

Explanation

Bacillus-shaped bacteria are rod-like, allowing greater surface area for nutrient absorption compared to cocci. This shape also aids in motility and division. Many bacilli can form endospores, enhancing survival in harsh conditions. Their elongated structure is a key morphological feature used in bacterial classification.

Submit

7. What shape is a spirillum bacterium

Explanation

Spirillum bacteria have a spiral or helical shape that aids in movement through viscous environments. This corkscrew motion increases efficiency in aquatic or host environments. The unique morphology differentiates them from rod and spherical bacteria and plays a role in their ecological niche and pathogenic potential.

Submit

8. What term describes bacteria arranged in pairs

Explanation

The prefix diplo- is used when bacteria are arranged in pairs after cell division. This arrangement results from incomplete separation following binary fission. Recognizing diplo arrangements helps microbiologists identify bacterial species and understand their reproductive patterns and structural behavior under microscopic observation.

Submit

9. What term describes grape-like bacterial clusters

Explanation

Staphylo describes bacteria arranged in irregular, grape-like clusters. This occurs when cells divide in multiple planes and remain attached. Staphylococcus species commonly show this pattern. The clustering impacts how bacteria interact with hosts and resist immune responses, making it an important diagnostic feature.

Submit

10. What is a biofilm

Explanation

A biofilm is a structured community of bacteria attached to a surface and embedded in a self-produced matrix. This matrix protects bacteria from antibiotics, immune responses, and environmental stress. Biofilms are significant in medical and industrial contexts because they increase bacterial survival and resistance.

Submit

11. Which cell structure is absent in prokaryotes

Explanation

Prokaryotes lack a nucleus, meaning their DNA is not enclosed by a membrane. This allows rapid transcription and translation. While they contain ribosomes and cytoplasm, the absence of a nucleus is the defining structural feature that separates them from eukaryotic cells.

Submit

12. Which organism is always prokaryotic

Explanation

Bacteria are always prokaryotic because they lack membrane-bound organelles and a true nucleus. Other organisms like amoeba and fungi are eukaryotic. This classification affects how bacteria reproduce, metabolize, and respond to treatments, making it essential for biological understanding and medical applications.

Submit

13. Which structure protects bacteria in harsh conditions

Explanation

Endospores are highly resistant structures formed by some bacteria to survive extreme conditions. They protect genetic material from heat, radiation, and chemicals. This ability explains why certain bacteria persist in harsh environments and why sterilization processes must be carefully designed.

Submit

14. Which term describes chain-like bacterial arrangements

Explanation

Strepto refers to bacteria arranged in chains due to division in a single plane. This linear arrangement is commonly seen in Streptococcus species. The pattern influences how bacteria spread in tissues and is a critical factor in laboratory identification and diagnosis.

Submit

15. Which feature is common to all bacteria

Explanation

The bacterial cell wall provides structural support and protection, maintaining shape and preventing osmotic lysis. It is composed mainly of peptidoglycan. This feature is universal among bacteria and is a primary target for antibiotics, highlighting its biological and medical importance.
