An injured adult otter has stem cells in its skin. A gardener takes a small piece of meristem tissue from a lavender plant.
Which statement describes what the stem cells from each organism could do?
The otter cells could replace damaged skin cells without cell division; the lavender cells could form a complete new plant without cell division.
The otter cells could multiply and replace damaged nerve cells; the lavender cells could multiply but form only cells normally found in shoots.
The otter cells could multiply and replace damaged skin cells; the lavender cells could multiply and develop into a complete new lavender plant.
The otter cells could multiply but not become specialised; the lavender cells could become specialised but not produce more meristem cells.
