Sample questions

1. Which of the following is the basic structural and functional unit of all known living organisms?

   1. Tissue
   2. Organ
   3. Cell
   4. System
   Show answer

   Answer: C. Cell

   The cell is universally recognized as the fundamental building block of life, responsible for all biological activities.

2. What is the primary function of connective tissue?

   1. Covering body surfaces
   2. Contracting to produce movement
   3. Transporting substances
   4. Supporting, connecting, or separating other tissues and organs
   Show answer

   Answer: D. Supporting, connecting, or separating other tissues and organs

   Connective tissues, such as bone, cartilage, and blood, provide structural support, bind tissues together, and facilitate transport and protection.

3. The cytoskeleton, a network of protein filaments within the cytoplasm, is primarily responsible for:

   1. Protein synthesis
   2. Cell shape, support, and movement
   3. Waste removal
   4. Energy storage
   Show answer

   Answer: B. Cell shape, support, and movement

   The cytoskeleton provides mechanical support, maintains cell shape, and plays a role in intracellular transport and cell motility.

4. What is the primary function of xylem tissue in plants?

   1. Transport of sugars produced during photosynthesis
   2. Transport of water and minerals from roots to leaves
   3. Storage of food reserves
   4. Photosynthesis
   Show answer

   Answer: B. Transport of water and minerals from roots to leaves

   Xylem is a vascular tissue that transports water and dissolved minerals upwards from the roots to the rest of the plant, and also provides structural support.

5. Which tissue type is composed of cells that have a spindle shape and are capable of contraction?

   1. Epithelial tissue
   2. Connective tissue
   3. Nervous tissue
   4. Muscle tissue
   Show answer

   Answer: D. Muscle tissue

   Muscle cells (fibers) are typically elongated and contain contractile proteins that allow them to shorten and generate force, resulting in movement.
