Anaerobic respiration happens in animals, plants and fungi.
The Table compares anaerobic respiration in human muscle cells and in yeast cells.

| is oxygen needed? | no |
Complete the Table.
When soil is flooded with water, the cells in plant roots respire anaerobically.
Suggest why.
Plants in flooded soil grow more slowly than plants in drained soil.
Suggest why.
