Avicennia, Rhizophora and Atriplex are

  1. Xerophytes

  2. Halophytes

  3. Hydrophytes

  4. Mesophytes
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

A. Xerophyte- are plant that has adaptations to survive in an environment with little liquid water, such as a hot or cold desert. for example- cacti, pineapple and some Gymnosperm plants.
B. Halophyte- grows in waters of high salinity, as they are salt-tolerant plant. for example- Avicennia, Rhizophora, Atriplex.
C. Hydrophytes- are aquatic plants, which grows only in or on water.for example- Lotus, water lily, salvinia.
D. Mesophytes- a plant need only a moderate amount of water. as they are terrestrial plants which are neither adapted to particularly dry nor particularly wet environments. for example-goldenrod, clover, Rosa multiflora

( Thus Correct answer is option- B.Halophytes )

Halophytes occur in

  1. Salty soil

  2. Desert

  3. Near river

  4. Rainy water
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Halophytes are naturally salt-tolerant plants that have evolved to grow in saline soils and waters with high salinity, such as in mangrove swamps, marshes and seashores. They are not usually found to grow near rivers or in rain water as they do not provide saline conditions. These plants have special physiological adaptations that enable them to absorb water from soils and from seawater, which have salt concentrations that nonhalophytes could not tolerate. Some halophytes are actually succulent, with a high water-storage capacity.

Halophytes are

  1. Salt resistant

  2. Fire resistant

  3. Cold resistant

  4. Sand loving

A Correct answer
Explanation

Halophytes are plants that have evolved to tolerate or thrive in environments with high salinity, such as salt marshes or coastal areas. They possess mechanisms to manage high salt concentrations in their tissues.

Mangrove roots are a habitat of

  1. Fish

  2. Echinoderms

  3. Crabs and Oysters

  4. Cuttlefish and Octopus
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Mangrove is an ecosystem that connects sea and land.  Mangrove trees are adapted to survive salt water. Mangroove roots are a habitat of fish. The roots provide structure and habitat for organisms such as fish to grow upon and hide behind. Oysters, mussels, sponges, snails, small fish are examples of fish that lives around mangrove roots.

Thus, the correct answer is 'Fish.'

Consider the following plants.
a. Bruguiera
b. Eugenia
c. Kandelia
d. Schima
Which of the above are mangrove trees?

  1. $1$ and $2$
  2. $1$ and $3$ only
  3. $2$ and $4$
  4. $1, 3$ and $4$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Among the listed plants, Bruguiera and Kandelia are well-known true mangrove trees adapted to saline intertidal zones. Eugenia and Schima are typical terrestrial or rainforest plants, not mangroves.

Which plant is found in mangrove zone?

  1. Rhizophora

  2. Acacia

  3. Pinus

  4. Tectona grandis
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rhizophora is a genus of tropical mangrove trees, sometimes collectively called true mangroves. The most notable species is the red mangrove. It is distributed in estuarine ecosystems throughout the tropics. Rhizophora mangle grows on aerial prop roots, which arch above the water level, giving this tree the characteristic mangrove appearance.

Therefore, the correct answer is option A.

Dunaliella is able to live in hypersaline lakes by developing a high osmotic pressure through accumulation of

  1. Proline

  2. Sorbitol

  3. Glycerol

  4. All of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Dunaliella are algal species which can survive in hypersaline lakes by preventing exosmosis. To achieve this, they store large amounts of Glycerol in their body which increases the osmotic pressure of their body fluids thus preventing exosmosis.
So, the correct answer is, 'Glycerol'.
