Which of the following is the primary genetic material in prokaryotic cells?

  1. DNA

  2. RNA

  3. Protein

  4. Lipid


Correct Option: A
Explanation:

Prokaryotic cells, such as bacteria and archaea, store their genetic information primarily in the form of DNA (deoxyribonucleic acid).

What is the main difference between prokaryotic and eukaryotic cells?

  1. Prokaryotes have a nucleus, while eukaryotes do not.

  2. Prokaryotes have membrane-bound organelles, while eukaryotes do not.

  3. Prokaryotes have a cell wall, while eukaryotes do not.

  4. Prokaryotes are unicellular, while eukaryotes are multicellular.


Correct Option:
Explanation:

The presence or absence of a nucleus is the key difference between prokaryotic and eukaryotic cells. Prokaryotic cells lack a nucleus and other membrane-bound organelles, while eukaryotic cells have a nucleus and various membrane-bound organelles.

Which of the following is an example of a prokaryotic cell?

  1. Bacteria

  2. Plant cell

  3. Animal cell

  4. Fungal cell


Correct Option: A
Explanation:

Bacteria are prokaryotic cells, meaning they lack a nucleus and other membrane-bound organelles.

Which of the following is an example of a eukaryotic cell?

  1. Bacteria

  2. Plant cell

  3. Animal cell

  4. Fungal cell


Correct Option: B
Explanation:

Plant cells are eukaryotic cells, meaning they have a nucleus and other membrane-bound organelles.

What is the function of the cell wall in plant cells?

  1. It provides structural support and protection.

  2. It regulates the movement of substances into and out of the cell.

  3. It contains the cell's genetic material.

  4. It produces energy for the cell.


Correct Option: A
Explanation:

The cell wall in plant cells provides structural support and protection, helping to maintain the cell's shape and protect it from mechanical damage.

What is the function of the nucleus in eukaryotic cells?

  1. It contains the cell's genetic material.

  2. It regulates the movement of substances into and out of the cell.

  3. It produces energy for the cell.

  4. It provides structural support and protection.


Correct Option: A
Explanation:

The nucleus in eukaryotic cells contains the cell's genetic material, including DNA, which is essential for controlling the cell's activities.

Which of the following is responsible for producing energy in eukaryotic cells?

  1. Mitochondria

  2. Chloroplasts

  3. Ribosomes

  4. Endoplasmic reticulum


Correct Option: A
Explanation:

Mitochondria are responsible for producing energy in eukaryotic cells through a process called cellular respiration.

What is the function of chloroplasts in plant cells?

  1. They produce energy through photosynthesis.

  2. They store genetic information.

  3. They regulate the movement of substances into and out of the cell.

  4. They provide structural support and protection.


Correct Option: A
Explanation:

Chloroplasts in plant cells are responsible for photosynthesis, the process by which plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Which of the following is responsible for protein synthesis in cells?

  1. Ribosomes

  2. Mitochondria

  3. Chloroplasts

  4. Endoplasmic reticulum


Correct Option: A
Explanation:

Ribosomes are responsible for protein synthesis in cells, using genetic information from DNA to assemble amino acids into proteins.

What is the function of the endoplasmic reticulum in cells?

  1. It transports materials within the cell.

  2. It produces energy for the cell.

  3. It contains the cell's genetic material.

  4. It provides structural support and protection.


Correct Option: A
Explanation:

The endoplasmic reticulum is a network of membranes that transports materials within the cell, including proteins and lipids.

Which of the following is responsible for packaging and distributing proteins in cells?

  1. Golgi apparatus

  2. Mitochondria

  3. Chloroplasts

  4. Endoplasmic reticulum


Correct Option: A
Explanation:

The Golgi apparatus is responsible for packaging and distributing proteins in cells, modifying them and sorting them for transport to their final destinations.

What is the function of lysosomes in cells?

  1. They digest and recycle cellular waste.

  2. They produce energy for the cell.

  3. They contain the cell's genetic material.

  4. They provide structural support and protection.


Correct Option: A
Explanation:

Lysosomes are small organelles that contain enzymes that digest and recycle cellular waste, damaged organelles, and foreign materials.

Which of the following is responsible for maintaining the cell's shape and providing structural support?

  1. Cytoskeleton

  2. Mitochondria

  3. Chloroplasts

  4. Endoplasmic reticulum


Correct Option: A
Explanation:

The cytoskeleton is a network of protein filaments and tubules that maintains the cell's shape, provides structural support, and facilitates cell movement.

What is the function of centrioles in animal cells?

  1. They help organize microtubules during cell division.

  2. They produce energy for the cell.

  3. They contain the cell's genetic material.

  4. They provide structural support and protection.


Correct Option: A
Explanation:

Centrioles are small, cylindrical structures found in animal cells that help organize microtubules during cell division, ensuring the proper distribution of chromosomes.

Which of the following is a type of asexual reproduction in which a single cell divides into two identical daughter cells?

  1. Binary fission

  2. Budding

  3. Fragmentation

  4. Spore formation


Correct Option: A
Explanation:

Binary fission is a type of asexual reproduction in which a single cell divides into two identical daughter cells, each with its own copy of the genetic material.
