Mangrove Trees

A mangrove is a tropical marine tree or shrub of genus Rhizophora. Mangroves have special aerial roots and salt-filtering tap roots that enable them to thrive in brackish water (brackish water is salty, but not as salty as sea water).

There are several species of mangrove trees found all over the world. Some prefer more salinity, while others like to be very close to large fresh water sources (such as a river). Some prefer areas that are sheltered from waves. Some species have their roots covered with sea water every day during high tide. Other species grow on dry land, but are still part of the ecosystem.

Mangroves need to keep their trunk and leaves above the surface of water. Yet they also need to be firmly attached to the ground so they are not moved by waves. There are three types of mangrove roots that play an important role for it: (1) support roots which directly pierce the soil. (2) level-growing roots which twist upwards and downwards, with the upward twists emerging on the water surface. (3) level-growing roots whose downward twist (sub-roots) appear on the water surface.

Any part of a root that appears above the water flows oxygen to the plant under the water surface. As the soil begins to build up, these roots produce additional roots that become embedded in the soil.

Soal 11

The main idea of the text is …

A. Mangroves grow on dry land

B. Mangroves are tropical marine trees

C. There are many species of mangroves

D. Mangrove roots filter the salt of sea water

E. Mangrove roots are attached firmly to the ground

Answer & Analysis

Key: B

Analysis: The first paragraph defines mangrove as “a tropical marine tree or shrub,” and the following paragraphs describe its habitat, species, and root system. Therefore, the general topic/main idea is about mangroves as tropical marine trees and their characteristics.

A. Incorrect: the text states that some species grow on dry land, but that is only one detail.

B. Correct: this summarizes the overall discussion (definition + characteristics).

C. Incorrect: species variety is mentioned, but it is not the main focus.

D. Incorrect: salt-filtering roots are described, but this is a supporting detail.

E. Incorrect: being firmly attached is part of root function, not the main idea.

Soal 12

We can conclude that most mangrove trees …

A. need salt to grow

B. grow on dry land

C. grow on sheltered areas

D. get oxygen from the water

E. grow near fresh water sources

Answer & Analysis

Key: C

Analysis: The text explains that some prefer sheltered areas and are adapted to brackish water and protection from waves. Although not all species are identical, the overall description emphasizes adaptation to coastal/brackish and sheltered environments.

A. Incorrect: they thrive in brackish water (partly salty), but it does not state that most strictly need salt.

B. Incorrect: only some species grow on dry land.

C. Correct: the passage highlights preference for sheltered areas from waves.

D. Incorrect: the text says roots above water supply oxygen to the plant under water, not that they get oxygen from water.

E. Incorrect: only some species grow near fresh water sources.

Soal 13

In order to grow well mangroves require the following, EXCEPT …

A. The roots twist upwards and downwards

B. The trunk should be above the water surface

C. The leaves should be above the water surface

D. The trees should be firmly attached to the ground

E. The parts of the plant under the water should have enough salt

Answer & Analysis

Key: E

Analysis: The text explains that mangroves must keep their trunk and leaves above water and be firmly attached to the ground. It also describes roots twisting upwards and downwards. However, it does not state that the parts under water “should have enough salt.” Instead, mangroves have salt-filtering roots to survive in brackish water.

A. Supported: root twisting upward and downward is described in detail.

B. Supported: trunk must be above water.

C. Supported: leaves must be above water surface.

D. Supported: must be firmly attached to the ground.

E. Correct (EXCEPT): the passage does not state that the submerged parts require enough salt; rather, mangroves filter salt and adapt to brackish water.
