  •  English    19     Public
    Test Review: Plant Cells; Animal Cells; Specialized Cells; Cell, Tissues, and Organs; Characteristics of Living Things; Virus; Vaccine; Species; Classification Keys
  •   Study   Slideshow
  • Name three cell components and its functions.
    Nucleus, Cell Wall, Cell Membrane, Chloroplast, Sap Vacuole, Mitochondria, Cytoplasm, Centrioles, Golgi Apparatus, Endoplasmic Reticulum, Lysosomes
  •  20
  • What are the main structures found in plant cells?
    Chloroplasts, cell wall, large central vacuole, nucleus, cell membrane
  •  15
  • How do a plant cell differ from an animal cells?
    Plant cells have a cell wall and chloroplasts, while animal cells do not. Plant cells have a large central vacuole compared to smaller vacuoles in animal cells
  •  15
  • What are the key components of animal cells?
    Nucleus, cell membrane, mitochondria, endoplasmic reticulum, Golgi apparatus, lysosomes
  •  15
  • Laabel the organelles in the cell.
    1. Nucleus, 2. Mitochondria, 3. Chroloplast, 4. Lysosomes, 5. Centrioles, 6. Cell Wall
  •  25
  • What are specialized cells?
    Cells that have specific structures and functions suited to their roles in an organism.
  •  10
  • Give two examples of a plant specialized cell and describe its functions.
    Palaside Cell / Root Hair Cell
  •  20
  • Give two examples of an animal specialized cell and describe its functions.
    Red Blood Cell / White Blood Cell / Sperm Cell / Egg Cell / Fat Cell / Muscle Cell / Ciliated Cell / Nerve Cell
  •  20
  • Discuss the relationship between cells, tissues, and organs.
    Cells are the basic unit of life, which group together to form tissues. Tissues then combine to form organs, which perform specific functions in the body.
  •  20
  • List the eight characteristics of living things.
    Made up of cells; Breathe; Sensitivity / Respond to stimuli; Require energy / nutrition; Movement; Excrete; Grow and develop; Reproduce
  •  20
  • What is a virus?
    A virus is a microscopic infectious agent that can only replicate inside the living cells of an organism.
  •  15
  • How does a virus differ from living organisms?
    Viruses cannot carry out metabolic processes on their own and need a host cell to reproduce.
  •  15
  • What is the purpose of a vaccine?
    Vaccines are designed to stimulate the immune system to recognize and fight specific pathogens.
  •  20
  • How do vaccines work?
    They introduce a harmless component of a pathogen to stimulate the immune system to produce antibodies and memory cells.
  •  25
  • How do vaccines help protect public health?
    By providing immunity to individuals, vaccines reduce the spread of diseases and protect vulnerable populations.
  •  25
  • What defines a species?
    A species is a group of organisms that can reproduce and produce fertile offspring.
