Sample questions

1. Which of the following plant tissues is characterized by being dead at maturity and providing structural support to the plant?

   1. Parenchyma
   2. Collenchyma
   3. Sclerenchyma
   4. Epidermis
   Show answer

   Answer: C. Sclerenchyma

   Sclerenchyma tissue consists of cells that are dead at maturity and have thickened, lignified secondary cell walls. These features provide rigidity and mechanical strength to various plant parts.

2. Which type of epithelial tissue is found lining the digestive tract and is specialized for absorption and secretion?

   1. Stratified squamous epithelium
   2. Simple cuboidal epithelium
   3. Simple columnar epithelium
   4. Pseudostratified columnar epithelium
   Show answer

   Answer: C. Simple columnar epithelium

   Simple columnar epithelium, often with microvilli, forms the lining of much of the digestive tract and is adapted for efficient absorption of nutrients and secretion of digestive enzymes.

3. Neurons are specialized cells that form nervous tissue. What is the primary function of a neuron?

   1. Muscle contraction
   2. Nutrient absorption
   3. Signal transmission
   4. Hormone production
   Show answer

   Answer: C. Signal transmission

   Neurons are the basic units of the nervous system, responsible for receiving, processing, and transmitting information through electrical and chemical signals.

4. Which of the following is a characteristic feature of dense irregular connective tissue?

   1. Fibers are densely packed and arranged in parallel bundles.
   2. Fibers are loosely arranged with a high proportion of ground substance.
   3. Fibers are densely packed and arranged in an interwoven, irregular pattern.
   4. Fibers are sparsely distributed in a gelatinous matrix.
   Show answer

   Answer: C. Fibers are densely packed and arranged in an interwoven, irregular pattern.

   Dense irregular connective tissue, found in the dermis of the skin, has collagen fibers arranged in a multidirectional, interwoven network, providing tensile strength in various directions.

5. Which of the following cell types is primarily responsible for the transport of sugars in plants?

   1. Tracheids
   2. Vessel elements
   3. Sieve tube elements
   4. Sclereids
   Show answer

   Answer: C. Sieve tube elements

   Sieve tube elements, along with companion cells, are the principal conducting cells of the phloem, responsible for the translocation of photosynthates (sugars) throughout the plant.
