Test: Biotechnology - 9 - Question 1

Which organelle is often referred to as the "powerhouse of the cell"?

Detailed Solution for Test: Biotechnology - 9 - Question 1
Mitochondria are often called the "powerhouses of the cell" because they are responsible for producing energy-rich molecules called ATP through aerobic respiration. ATP is the primary energy currency used by cells for various metabolic processes.
Test: Biotechnology - 9 - Question 2

What is the primary function of the plasma membrane in a cell?

Detailed Solution for Test: Biotechnology - 9 - Question 2
The plasma membrane, also known as the cell membrane, is responsible for regulating the entry and exit of materials into and out of the cell. It acts as a selectively permeable barrier, controlling the passage of ions, molecules, and nutrients, thereby maintaining the cell's internal environment.

Test: Biotechnology - 9 - Question 3

Which type of plastid is responsible for storing carbohydrates, such as starch, in plant cells?

Detailed Solution for Test: Biotechnology - 9 - Question 3
Leucoplasts are colorless plastids found in plant cells and are responsible for storing carbohydrates, particularly starch. They are involved in the storage of energy reserves in the form of polysaccharides.
Test: Biotechnology - 9 - Question 4
What is the function of the Golgi Apparatus in a cell?
Detailed Solution for Test: Biotechnology - 9 - Question 4
The Golgi Apparatus is responsible for modifying, sorting, and packaging proteins and lipids produced in other parts of the cell. It prepares these molecules for transport to their specific destinations within or outside the cell.
Test: Biotechnology - 9 - Question 5
Where are ribosomes primarily involved in protein synthesis located within a eukaryotic cell?
Detailed Solution for Test: Biotechnology - 9 - Question 5
Ribosomes that are primarily involved in protein synthesis are located in the cytoplasm of eukaryotic cells. These ribosomes translate the genetic code carried by mRNA into protein sequences.
Test: Biotechnology - 9 - Question 6
What is the primary function of the nucleolus within the nucleus of a cell?
Detailed Solution for Test: Biotechnology - 9 - Question 6
The nucleolus is primarily responsible for the synthesis of ribosomal RNA (rRNA), which is a crucial component of ribosomes. Ribosomes are involved in protein synthesis within the cell.
Test: Biotechnology - 9 - Question 7
Which organelle is responsible for trapping light energy during photosynthesis in plant cells?
Detailed Solution for Test: Biotechnology - 9 - Question 7
Chloroplasts are responsible for trapping light energy during photosynthesis in plant cells. They contain pigments like chlorophyll that capture light energy and convert it into chemical energy in the form of glucose.
Test: Biotechnology - 9 - Question 8
Which organelle is responsible for the detoxification of harmful substances in the cell?
Detailed Solution for Test: Biotechnology - 9 - Question 8
The smooth endoplasmic reticulum (SER) is involved in the detoxification of harmful substances, such as drugs and toxins, in the cell. It plays a crucial role in drug metabolism and detoxification processes.
Test: Biotechnology - 9 - Question 9
Which cellular structure provides shape and mechanical resistance to the cell and is involved in cell motility?
Detailed Solution for Test: Biotechnology - 9 - Question 9
The cytoskeleton is a network of protein filaments that provides structural support to the cell and is involved in cell motility. It helps maintain the cell's shape and allows for various cellular movements.
Test: Biotechnology - 9 - Question 10
What is the primary function of microbodies within a cell?
Detailed Solution for Test: Biotechnology - 9 - Question 10
Microbodies are organelles responsible for detoxifying harmful substances in the cell. They contain enzymes that help in the breakdown and detoxification of various molecules and compounds.
