Evergreen trees lose their leaves steadily throughout the year rather than shedding all leaves in a single season. How should this statement be judged?

Difficulty: Easy

Correct Answer: The statement is correct; evergreen trees continually shed some leaves all year long

Explanation:


Introduction / Context:
This question tests understanding of basic plant biology and the difference between deciduous and evergreen trees. Many people think that evergreen trees keep their leaves forever, which is not accurate. The statement given describes how evergreen trees handle leaf loss and asks whether that description is correct.


Given Data / Assumptions:

  • The statement claims that evergreen trees lose their leaves steadily all year.
  • Evergreen trees retain green foliage throughout the year and do not appear leafless.
  • Deciduous trees typically shed all or most of their leaves during one season, often in autumn.
  • The options ask whether the statement is correct or not, with different explanations.


Concept / Approach:
Evergreen trees are called evergreen because they always appear to have green foliage. However, this does not mean that individual leaves live forever. Leaves of evergreen trees age and die, but instead of falling all at once in one season, they are replaced gradually. At any time of the year, some leaves are falling while others remain, so the tree keeps its green appearance. This means that the statement that evergreen trees lose their leaves steadily throughout the year is a correct description.


Step-by-Step Solution:

Step 1: Recall that deciduous trees shed their leaves in a particular season, often in response to cold or dry conditions. After shedding, they may remain leafless for some time. Step 2: Contrast this with evergreen trees such as pine, spruce, or many tropical evergreens, which always appear to be covered in leaves or needles. Step 3: Understand that evergreen trees still go through natural leaf aging. Individual leaves or needles only live for a certain number of years and then fall off. Step 4: Therefore, even though the tree as a whole remains green, some leaves are constantly being shed and replaced. This matches the idea of losing leaves steadily throughout the year. Step 5: Evaluate option a, which states that the statement is correct and explains that evergreen trees continually shed leaves. This fits the botanical facts. Step 6: Reject options that claim evergreens never lose leaves, or that they drop all leaves at one time, because these describe incorrect or deciduous behavior, not evergreen behavior.


Verification / Alternative check:
Botany references explain that evergreen conifers like pines keep their needles for several years before they fall, but they are losing some needles every year. Many broad leaved evergreens, such as certain tropical trees, also shed older leaves as new ones grow. Field observations show that you can find fallen leaves from evergreen trees at almost any time of year, confirming the continuous but partial leaf loss pattern described in the statement.


Why Other Options Are Wrong:

  • The option claiming that evergreen trees never lose any leaves is wrong, because no leaf lives forever.
  • The option claiming that evergreen trees drop all leaves at once is wrong and confuses them with deciduous trees.
  • The option suggesting the statement is true only for deciduous trees is wrong because deciduous trees display a strong seasonal leaf drop, not a steady year round pattern.


Common Pitfalls:
Many learners misinterpret the word evergreen and imagine that these trees literally never lose leaves. The correct understanding is that evergreens always have some green leaves present but still replace old leaves with new ones. Failing to separate the appearance of the whole tree from the life cycle of individual leaves leads to wrong answers. Remember: evergreen means the tree remains green overall, not that each leaf is permanent.


Final Answer:
The statement is correct; evergreen trees continually shed some leaves all year long
