Which of the above is/are correct? Answer:
1, 2 & 3
Notes:
Plants of saline water - Halophytes: This pair is correct. Halophytes are plants that can tolerate and grow in saline or salty environments. They have adapted mechanisms to deal with high salt concentrations in the soil or water, allowing them to thrive in such challenging conditions.
Plants of acidic soil - Oxylophytes: This pair is correct. Plants that grow in acidic soil are also typically referred to as "acidophytes" or "ericaceous plants."
Plants growing on the sand - Psammophytes: This pair is correct. Psammophytes are plants that are well-adapted to grow in sandy environments. These plants have specific characteristics that enable them to tolerate the dry, nutrient-poor, and shifting conditions found in sand dunes and sandy soils.
