Very Short Answer Questions

1. Identify the type of tissue found at the following locations:
   • Tip of plant roots: Apical meristem.
   • Lower surface of leaves: Stomatal guard cells.
   • Inner lining of the intestine: Columnar epithelium.
   • Joint between two long bones: Cartilage.
   • Walls of leaf veins: Vascular tissue (Xylem and Phloem).
   • Gritty texture in pear skin: Sclereids.
2. Which is the least specialized tissue in plants?
   • Parenchyma.
3. Provide one term for each description:
   • Group of similar cells performing a function: Tissue.
   • Least specialized cells in plants: Parenchyma.
   • Cells responsible for increasing stem/root diameter in dicots: Lateral meristem.
4. Identify one location for each tissue type:
   • Meristematic tissue: Root tips.
   • Cartilage: Ear pinna.
   • Squamous epithelium: Lung alveoli.
   • Sclerenchyma: Plant stem.
   • Ciliated epithelium: Respiratory tract.
   • Ligament: Between bones.
5. Identify cell types in the following:
   • Salivary gland: Glandular epithelial cells.
   • Brain: Neurons.
   • Skin surface: Squamous epithelial cells.
   • Inner lining of the windpipe: Ciliated epithelial cells.

Short Answer Questions

1. Where is ciliated epithelium found in humans and what is its role?
   • Found in the respiratory tract, it assists in moving mucus and trapped particles.
2. Define the following terms:
   • Tissue: A collection of similar cells performing a particular function.
   • Organ: Structure composed of different tissues working for a specific function.
   • Organ system: Group of organs collaborating for a common physiological purpose.
   • Lymph: A fluid connective tissue playing a role in immunity.
   • Neuron: A specialized cell transmitting nerve impulses.
3. Locations of specific tissues:
   • Sclerenchyma: Plant stems.
   • Collenchyma: Leaf stalks.
   • Ciliated columnar epithelium: Respiratory tract.
   • Cardiac muscles: Heart.
4. What tissues are present in the human heart?
   • Cardiac muscle, connective tissue, and nerve tissue.
5. Are clustered eggs considered a tissue? Explain.
   • No, because tissues are groups of similar cells working for a common function, whereas eggs don’t form such a unit.
6. List three muscle types in humans with examples:
   • Skeletal muscle: Biceps.
   • Cardiac muscle: Heart.
   • Smooth muscle: Intestinal walls.

Long Answer Questions

1. Differentiate between the following pairs:
   • Parenchyma vs. Collenchyma: Parenchyma has thin walls and is involved in storage, whereas collenchyma has unevenly thickened walls providing mechanical support.
   • Meristematic vs. Permanent tissue: Meristematic tissues contain actively dividing cells, while permanent tissues consist of differentiated cells that no longer divide.
   • Blood vs. Lymph: Blood consists of red and white cells along with platelets, while lymph is a fluid with fewer cells and plays a role in immunity.
   • Bone vs. Cartilage: Bones are hard and porous due to calcium salts, whereas cartilage is flexible and less porous.
   • Voluntary vs. Involuntary muscles: Voluntary muscles are striated and controlled consciously, while involuntary muscles are non-striated and function automatically.
2. Explain the differences between:
   • Cell and Tissue: A cell is the basic unit of life, while a tissue is a group of similar cells performing a shared function.
   • Organ and Organism: An organ is a structure made of tissues, and an organism is a living entity with various organ systems.
   • Organ and Organelle: Organs are structures within organisms, while organelles are specialized structures within cells.
   • Organ and Organ System: An organ system is a group of organs that collaborate to perform complex functions.

Structured/Application Questions

1. Analyze the phloem tissue diagram:
   • Identify the tissue: Phloem, responsible for food transport.
   • Label the parts 1-4.
   • Typical location: Stems and leaves.
   • Functions of the labeled parts: (Descriptions for each labeled part should be given).
2. Examine the neuron diagram:
   • Identify the cell: Neuron.
   • Label parts 1-6.
   • Typical location and function: Found throughout the nervous system; it transmits nerve impulses.
3. Identify animal tissues from diagrams:
   • Tissue A and B identified.
   • Label all marked parts.
   • Common function: Both provide structural support.
   • Functional difference: One may be involved in movement, the other in protection.
   • Location examples: (Specific locations for each tissue type).
4. Describe the two types of fibrous connective tissue:
   • Tendons: Connect muscles to bones; provide strength and flexibility.
   • Ligaments: Connect bones to other bones; provide stability to joints.
   • Include a diagram with labeled parts.
