  • Tay-Sachs disease causes lysosomes to rupture. How would this affect the cell?
    Ruptured lysosomes would release digestive enzymes into the cytoplasm, leading to cellular damage and cell death.
  • Which of the following is a function of the nucleus in the cell body of a neuron?
    The nucleus in a neuron stores genetic information and regulates gene expression necessary for cell function.
  • Which of the following statements is false regarding the nucleus of eukaryotic cells? a) It contains the cell's DNA b) It is surrounded by a single membrane c) It has nuclear pores d) It contains the nucleolus
    b) It is surrounded by a single membrane
  • The largest vacuoles are typically found in which type of cells?
    The largest vacuoles are typically found in plant cells, where they help maintain turgor pressure.
  • What is the purpose of cilia and flagella?
    Cilia and flagella are used for cell movement and the movement of substances across cell surfaces.
  • Where are ribosomes usually located in animal and plant cells?
    Ribosomes are usually located in the cytoplasm and on the rough endoplasmic reticulum in both animal and plant cells.
  • How do endodermal cells differ from other types of cells?
    Endodermal cells are derived from the innermost germ layer and give rise to the lining of the digestive and respiratory systems.
  • What structure represents the endoplasmic reticulum (ER) of the cell?
    The endoplasmic reticulum (ER) is represented by a network of membranous tubules and sacs, with the rough ER having ribosomes on its surface and the smooth ER lacking them.
  • What are eukaryotic organelles and how do they differ between animal and plant cells?
    Eukaryotic organelles are specialized structures within eukaryotic cells, many of which are membrane-bound. Animal and plant cells share most organelles, but lysosomes are unique to animal cells, while chloroplasts and cell walls are unique to plant cells.
  • Which organelles are unique to plant cells and not found in animal cells?
    Chloroplasts and cell walls are unique to plant cells and not found in animal cells.
  • Are ribosomes considered membranous or non-membranous organelles, and why?
    Ribosomes are considered non-membranous organelles because they are not made up of membranes.
  • What is the difference between free ribosomes and attached ribosomes?
    Free ribosomes float in the cytoplasm and make proteins that remain in the cytoplasm, while attached ribosomes are bound to the rough endoplasmic reticulum and make proteins that enter the rough ER.
  • What is the process called that ribosomes use to build proteins?
    The process ribosomes use to build proteins is called translation.
  • Which organelles are shared by both animal and plant cells?
    Organelles shared by both animal and plant cells include mitochondria, cell membrane, rough and smooth endoplasmic reticulum, ribosomes, Golgi apparatus, and peroxisomes.
  • What is the general sequence of topics covered in the lesson map for eukaryotic organelles?
    The lesson map covers the endomembrane system and protein secretion first, then cellular digestion and energy-related organelles, followed by the cytoskeleton and cell junctions.
  • What is the function of the rough endoplasmic reticulum in relation to ribosomes?
    The rough endoplasmic reticulum provides a surface for ribosomes to attach and is involved in the synthesis and processing of proteins that will be secreted or sent to specific organelles.
  • What is the significance of the lesson map for students studying eukaryotic organelles?
    The lesson map helps students understand the sequence and structure of topics, allowing them to track progress and anticipate upcoming content.
