Cell Organelles And Their Functions Trivia
1.
What is the function of a cell wall?
Answer:
Structure and protection
Explanation:
The function of a cell wall is to provide structure and protection to the cell. It acts as a rigid outer layer that gives shape to the cell and protects it from external mechanical forces. The cell wall also helps in preventing the cell from bursting due to osmotic pressure. Additionally, it provides a barrier against pathogens and other harmful substances, ensuring the cell's integrity and survival.
2.
What role do chloroplasts play?
Answer:
Photosynthesis
Explanation:
Chloroplasts are responsible for photosynthesis, the process by which plants convert sunlight into energy. They contain chlorophyll, a pigment that captures light energy, and other molecules necessary for the chemical reactions involved in photosynthesis. Through this process, chloroplasts produce glucose and oxygen, which are essential for the plant's growth and survival. Therefore, the correct answer is photosynthesis.
3.
What is the function of the central vacuole?
Answer:
Increases the cell surface area, stores metabolic waste, water and nutrients.
Explanation:
The central vacuole functions to increase the cell surface area and store metabolic waste. It helps maintain the shape and structure of the cell by occupying a large portion of the cell's volume. Additionally, the central vacuole stores various substances such as water, ions, nutrients, and waste products. By storing metabolic waste, the vacuole prevents the accumulation of harmful substances within the cell. Moreover, the expansion and contraction of the central vacuole can also contribute to changes in cell size and shape.
4.
What is the role of nucleolus?
Answer:
Assembly of Subunits of Ribosomes.
Explanation:
The nucleolus is responsible for the assembly of subunits of ribosomes. Ribosomes are essential for protein synthesis, and they consist of two subunits that are synthesized separately and then assembled in the nucleolus. Once the subunits are assembled, they are transported out of the nucleolus to the cytoplasm, where they can join together and function as ribosomes. Therefore, the role of the nucleolus is specifically related to the assembly of ribosomal subunits, rather than other cellular processes such as lipid modification, protein synthesis, or controlling substances entering or leaving the cell.
5.
What is the role of ribosomes?
Answer:
Protein synthesis
Explanation:
Ribosomes play a crucial role in protein synthesis, which involves the creation of new proteins. They act as the site where mRNA is translated into proteins by assembling amino acids in the correct order. This process is essential for the functioning and maintenance of cells, as proteins are involved in various cellular processes such as enzyme activity, cell signaling, and structural support. Therefore, the role of ribosomes in protein synthesis is vital for the overall functioning and survival of cells.
6.
What is the function of rough ER?
Answer:
Protein synthesis, processing, and transport.
Explanation:
The rough endoplasmic reticulum (rough ER) is a complex organelle within a cell that serves several important functions, primarily related to protein synthesis, processing, and transport. It plays a crucial role in the proper functioning of the cell and is characterized by its rough appearance due to the presence of ribosomes attached to its surface.
7.
What is the function of smooth ER?
Answer:
Makes lipids, degrades fats, and inactivates toxins.
Explanation:
Smooth ER is responsible for making lipids, degrading fats, and inactivating toxins. It does not have a role in communication between cells, organizing DNA, organizing and moving internal parts of the cell, or digesting and recycling materials. Therefore, the correct answer is that smooth ER is involved in lipid synthesis, fat degradation, and toxin inactivation.
8.
What is the importance of the Golgi Body?
Answer:
It modifies, sorts, and ships lipids for export or for insertion into the cell membrane.
Explanation:
The Golgi Body plays a crucial role in the cell by modifying, sorting, and shipping lipids for export or for insertion into the cell membrane. This process is essential for maintaining the integrity and functionality of the cell membrane. By modifying and sorting lipids, the Golgi Body ensures that they are properly distributed within the cell and transported to their intended destinations. This is important for various cellular processes, including cell signaling, membrane repair, and the export of lipids to other parts of the body.
9.
What is the primary source of energy for the aerobic energy system?
Answer:
Glucose
Explanation:
The primary source of energy for the aerobic energy system is glucose. This system relies on the aerobic metabolism of glucose (and other carbohydrates) to produce ATP (adenosine triphosphate), which is the primary energy currency of cells. Aerobic metabolism occurs in the presence of oxygen and involves the breakdown of glucose through processes such as glycolysis, the citric acid cycle (Krebs cycle), and oxidative phosphorylation in the mitochondria.
10.
What role does the cytoskeleton play?
Answer:
Structurally supports and gives shape to a cell. Moves the cell and its components.
Explanation:
The cytoskeleton provides structural support to the cell, maintaining its shape, and is involved in various cellular movements. It organizes the cell's components, facilitates intracellular transport, and is essential for cell division and motility.
