• What are the two main types of cells discussed in the study material?

  Prokaryotic and Eukaryotic cells
• What is a key structural difference between prokaryotic and eukaryotic cells?

  Eukaryotic cells contain a nucleus, while prokaryotic cells do not.
• What are the key structural components of prokaryotic and eukaryotic cells?

  • Prokaryotic cells:
  • No nucleus
  • Membraneless nucleoid region
  • Ribosomes (smaller subunits)
  • Eukaryotic cells:
  • Nucleus with nuclear envelope
  • Membrane-bound organelles (e.g., mitochondria, endoplasmic reticulum)
  • Ribosomes (larger subunits)
• What might be the function of structures present in eukaryotic cells but not in prokaryotic cells?

  They allow eukaryotic cells to carry out more functions and have greater specificity.
• What is the general shape of prokaryotic cells?

  Typically rod-shaped, spherical, or spiral.
• What are the different shapes of bacteria mentioned?

  1. Spherical - Cocci
  2. Rod-shaped - Bacilli
  3. Spiral - Spirillum
  4. Comma-shaped - Vibrio
• How do cocci-shaped bacteria differ in their cell wall structure?

  They may be gram-positive with a thick peptidoglycan layer or gram-negative with a thin peptidoglycan wall.
• What type of bacteria are Bacilli?

  Rod-shaped bacteria.
• What distinguishes Spirillum from Spirochete bacteria?

  Spirillum are gram-negative and rigid with external flagella, while Spirochete are thin, flexible, and have internal periplasmic flagella.
• What is the shape of Vibrio bacteria?

  Comma-shaped.
• What is a key characteristic of eukaryotic cells?

  They contain a nucleus.
• What are organelles?


  Structures within the cytoplasm that perform specific jobs in the cell.
• What is the function of mitochondria in eukaryotic cells?

  They provide energy to the cell.
• How do prokaryotic and eukaryotic ribosomes differ?

  Eukaryotic ribosomes are larger and more complex, while prokaryotic ribosomes are smaller and scattered throughout the cytoplasm.
• What is the primary difference in reproduction between prokaryotes and eukaryotes?

  Most eukaryotes reproduce sexually, while prokaryotes reproduce asexually.
• What is a common feature of prokaryotic cell walls?

  They are rigid and composed of peptidoglycan.
• What is the function of connective tissue in animals?

  It provides structure, shapes, and protection.
• What are the four types of animal tissues and their functions?

  1. Epithelial Tissue:

  • Covers surfaces and lines cavities
  • Provides protection

  1. Connective Tissue:

  • Provides structure and support

  1. Muscle Tissue:

  • Responsible for movement

  1. Nervous Tissue:

  • Transmits electrical signals and supports neurons
• What is the role of neurons in nervous tissue?

  They sense stimuli and transmit electrical signals throughout the body.
• What is the function of glial cells?

  They provide physical support for neurons and regulate the extracellular fluid.
• What is the importance of having a tissue level in biological organization?

  It results in tissue formation that performs common functions.
• What happens if a tissue is injured?

  Both the cells and the cell structure in the organ are also damaged.
• How do the varying shapes and arrangements of epithelial tissue suggest their function?

  They indicate the specific roles they play in protection, secretion, and absorption.
• What is the primary function of muscle tissue?

  To facilitate movement.
• What is the role of the cell body in a neuron?

  It controls all the functions of the cell.
• What is the function of dendrites in a neuron?

  They receive impulses from other neurons.
• What is the function of the axon in a neuron?

  It transmits impulses to other neurons.
• What is the role of blood vessels in the body?

  They flow blood throughout the body.
• What are the five kingdoms of cellular characteristics mentioned?

  1. Kingdom Plantae
  2. Kingdom Fungi
  3. Kingdom Animalia
  4. Kingdom Protista
  5. Kingdom Monera
• What is the purpose of the PowerPoint presentation mentioned in the study material?

  To present the title, objectives, introduction, discussion, conclusion, and quiz.
• What is the significance of the quiz mentioned in the study material?

  It assesses understanding of the material covered.
• How many items are in the multiple-choice quiz mentioned?

  20 items.
• What is the importance of classifying different types of tissues in animals?

  It helps to describe the structure and function of each type of tissue.
• How can understanding tissue classification help in analyzing tissue samples?

  It allows for correct identification of tissues based on their structure and function.
