Which one of the following is false?a)The majority of leafy liverworts...
False Statement:
The false statement is option C: Mosses have lobes in their leaves but leafy liverworts lack.
Explanation:
To understand why option C is false, let's examine the characteristics of both mosses and leafy liverworts:
Mosses:
- Mosses are a type of non-vascular plants belonging to the division Bryophyta.
- They have simple leaves with a single, undivided blade.
- The leaves of mosses are usually arranged in a spiral pattern around the stem.
- Some mosses may have lobes or teeth at the leaf margins, giving them a slightly lobed appearance.
Leafy Liverworts:
- Leafy liverworts are also non-vascular plants belonging to the division Marchantiophyta.
- They have flattened leaf-like structures called "leaves" that are arranged in two or three rows.
- The leaves of leafy liverworts lack lobes or teeth along the margins and are more simple in structure compared to moss leaves.
Explanation of Option C:
Option C states that mosses have lobes in their leaves, but leafy liverworts lack lobes. However, this statement is incorrect because some mosses may have lobes, but not all mosses have lobed leaves. Similarly, while leafy liverworts generally lack lobes, there are some species of leafy liverworts that may have lobes or tooth-like structures on their leaves.
Corrected Explanation:
To make the statement true, we can modify it to say "Some mosses may have lobes in their leaves, whereas leafy liverworts generally lack lobes." This revised statement accurately reflects the variation in leaf morphology within mosses and leafy liverworts.
Conclusion:
In summary, option C is false because it incorrectly states that mosses have lobes in their leaves while leafy liverworts lack lobes. Mosses and leafy liverworts vary in their leaf structure, and while some mosses may have lobes, not all of them do. Similarly, leafy liverworts generally lack lobes, but there are exceptions to this rule.
Which one of the following is false?a)The majority of leafy liverworts...
The majority of leafy liverworts have a structure that is similar to mosses. Oil bodies are present in leafy liverworts but not in mosses. Mosses lack lobes in their leaves, but leafy liverworts do. While the leaves of mosses are organized in spirals, those of leafy liverworts grow in two or three rows.
