Question

Halophytes occur in:
(a)Salty
(b)Desert
(c)Near the river
(d)Rainy water

Answer 1

Hint: Halophytes are commonly described as seed-bearing rooted plants ( i.e. grasses, succulents, herbs, shrubs, and trees) that grow from coastal sand dunes, salt marshes, and mudflats to inland deserts, salt flats, and steppes in a wide range of saline habitats.

Complete answer:
-The prefix 'halo' and the root 'phyto' are respectively translated as salt and herb. Halophytes are sometimes described as salt-tolerant, salt-loving, or saltwater plants.
- In any climate zone where there is vegetation, from the tropics to the tundra, these highly adaptable species, which can accrue relatively large quantities of salt, are found.
-These opportunistic plants are often able to take advantage of less saline moisture within the soil profile with their vigorous growth and root development and adjust to seasonal variability in salinity by altering germination, growth, and reproduction cycles to best suit their survival needs.

Additional Information: -Intercellular transport mechanisms (pumps) transfer excess salt ions from surface cells to the outside of the leaf or stem leaving clear crystal deposits until the water has evaporated.
-Another exclusionary mechanism (known as intraplant allocation) that predominates at the root level and contributes to overall plant salt tolerance is the storage or compartmentation of excess salts within certain plant organs.
-In order to limit its translocation to the rest of the plant, many halophytes are able to confine excess salts within their extensive root systems and the lower sections of the shoot as a result of stomatal closure and decreased transpiration rates.
-External and internal exclusionary processes also help promote the production of healthy leaves and the overall growth of biomass while minimizing the disruption of entire plants caused by increased salinity.
So, the correct answer is ‘Salty’.

Note: -Some halophytes are capable of collecting and converting toxic heavy metal (i.e. lead, cadmium, and selenium) levels into benign organic compounds, thus assisting in phytoremediation.
