Spot the odd cell part

Read exercise and reference answers
Questions
  1. Items
    1. Mitochondria
    2. Ribosome
    3. Nucleus
    4. Chloroplast
    Reason
    Chloroplasts are present only in plant cells, not animal cells.
    Odd item
    Chloroplast
  2. Items
    1. Cell wall
    2. Plasma membrane
    3. Lysosome
    4. Cytoplasm
    Reason
    Cell wall is a plant-cell feature; animal cells lack it.
    Odd item
    Cell wall
Instructions
Each round shows four cell parts. Tap the one that does not belong with the others.
