Difficulty: EasyDecoding Low-Frequency Academic and Technical Words

Unlike typical land plants that perish when exposed to high levels of salt, the halophyte thrives in coastal marshes. These specialized species have evolved unique cellular mechanisms to filter out excess sodium from their root systems, allowing them to flourish in highly saline environments where other vegetation would quickly wither. Consequently, these salt-tolerant plants play a vital role in stabilizing shoreline ecosystems against erosion.

As it is used in the passage, what does the underlined word halophyte most nearly mean?

  1. A
    plant that grows exclusively in freshwater environments
  2. B
    plant that is easily damaged by salt
  3. plant adapted to growing in saline or salty conditionsAnswer
  4. D
    plant that lacks a root system entirely

Answer

plant adapted to growing in saline or salty conditions
The correct answer is correct because the passage explicitly describes the plant as thriving where others perish from salt exposure, filtering out excess sodium, and flourishing in highly saline environments. These details indicate that the plant is adapted to salty or saline conditions.

Step-by-Step Solution

1
Locate the target word in the passage and examine its immediate surrounding context.
The word is introduced in contrast to typical plants that perish when exposed to salt, stating that this species thrives in coastal marshes.
This establishes that the target word refers to a type of plant that is resistant to salt, unlike typical plants.
2
Analyze subsequent sentences for further explanatory context clues.
The text describes how the species filters out excess sodium and flourishes in highly saline environments.
These details confirm that the plant is specifically adapted to environments with high salt (sodium) content.
3
Match the findings with the provided options.
The description matches the definition of a plant adapted to saline or salty conditions.
This confirms the correct option based on the explicit context clues.
