The 20 questions

  1. What is a tissue?

    • A group of similar cells that work together to perform a particular function
    • A group of different organs that share one function
    • A population of organisms of one species in an area
    • A single cell with specialised organelles

  2. What is an organ?

    • A structure made of different tissues that work together for a specific function
    • A group of organs working together in the body
    • A single type of tissue performing one function
    • A specialised cell that has lost its nucleus

  3. What is an organ system?

    • A type of cell found in every organ
    • A single organ that works alone
    • A group of organs that work together to carry out a major body function
    • A collection of cells from different organisms

  4. Why are the cells of multicellular organisms organised into tissues, organs and systems?

    • Division of labour allows specialised cells to carry out functions more efficiently together
    • It prevents cells from communicating with each other
    • Each cell needs to be able to perform every function on its own
    • It allows cells to stop dividing once they are specialised

  5. A group of cells lining the small intestine has microvilli to increase absorption. At which level of organisation is this?

    • Population, because many intestines are involved
    • Tissue, where cells with the same specialisation form a layer
    • Organ system, because the whole gut works as one
    • Cell, because a single cell does all the work

  6. Which example is a correct pairing of level and structure?

    • Organ: heart
    • Tissue: heart
    • System: muscle cell
    • Cell: digestive system

  7. Which statement about the organisation of plants is correct?

    • Plants have no tissues because they are not animals
    • Plants do not form organ systems at all
    • Plants have tissues, such as xylem and phloem
    • Plant organs contain only one cell type

  8. What is the main role of xylem in a plant?

    • To transport water and mineral ions upwards from the roots
    • To transport sugars from the leaves to other parts of the plant
    • To provide support by containing starch in cells
    • To protect the plant against infection by producing mucus

  9. A tissue is made of cells that all carry out the same function. Which name fits this best?

    • Organ system
    • Simple tissue
    • Stem cell line
    • Chromosome set

  10. Which of these is a complex tissue in plants?

    • Mesophyll made of a single cell layer only
    • Phloem sieve cells only
    • Epidermis made only of identical cells
    • Xylem, which contains several cell types including vessels and fibres

  11. What is the advantage of organisation into systems for the body as a whole?

    • Coordinated activity of organs allows the whole organism to respond to changing conditions
    • It ensures that all organs are the same size
    • It prevents the need for a blood supply
    • It makes every cell immune to disease

  12. Why must tissues in a large organism be close to a blood supply?

    • Blood is needed to form the cell wall
    • Oxygen and nutrients must reach cells, which are too far
    • Blood stops cells from dividing
    • Cells must be close to blood to make their own blood cells

  13. Which level of organisation contains the most different cell types working together?

    • Tissue made of one cell type
    • Chromosome
    • Organ or organ system
    • Cell

  14. What type of structure is a leaf?

    • A tissue made of only one cell type
    • An organ system containing roots and stems
    • A cell with a large central vacuole
    • An organ made of several tissues such as epidermis, mesophyll and vascular tissue

  15. A stem cell in an adult tissue replaces a lost specialised cell. Which level of organisation does this affect most directly?

    • Population
    • Organ system
    • Ecosystem
    • Tissue

  16. Which statement about the tissues in a mammal's heart is correct?

    • The heart is a system containing the lungs
    • The heart contains cardiac muscle tissue, along with connective and nervous tissues
    • The heart consists only of one type of cell, the red blood cell
    • The heart has no tissues because it is an organ

  17. Why are tissues organised into organs rather than working individually?

    • Different tissues can work together
    • Organs are needed to stop tissues from dividing
    • Organs are a way of storing genetic information
    • Tissues cannot survive unless they are inside an organ

  18. Which tissue is made of cells that contract to produce movement?

    • Connective tissue
    • Epithelial tissue
    • Xylem tissue
    • Muscle tissue

  19. Why does the stomach contain several tissue types?

    • Its wall has epithelium, muscle and connective tissue, each doing a different job in digestion
    • Every tissue in the stomach has exactly the same function
    • The stomach is made of blood vessels only
    • The stomach contains several different organisms that digest food

  20. Which order lists the levels of organisation from smallest to largest?

    • Tissue, cell, organ, organism, organ system
    • Cell, tissue, organ, organ system, organism
    • Organism, organ system, organ, tissue, cell
    • Organ, tissue, cell, organ system, organism
