Final answer:
Adding saltwater to a plant can have negative effects on its growth and survival. Saltwater has a higher concentration of salt compared to the plant's cells, which can disrupt the osmotic balance and lead to dehydration and tissue damage.
Step-by-step explanation:
Adding saltwater to a plant can have negative effects on its growth and survival. Saltwater has a higher concentration of salt compared to the plant's cells, which can disrupt the osmotic balance. This can lead to dehydration and damage to the plant's tissues. In addition, excess salt can prevent the plant from absorbing necessary nutrients and water from the soil, further inhibiting its growth.
