Based on the analysis of each leaf in the image, we can determine which one is a simple leaf by understanding the key botanical distinction:
-
Simple Leaf: A leaf with a single, undivided blade. The entire leaf structure, from the petiole to the tip, is one continuous piece.
-
Compound Leaf: A leaf where the blade is divided into multiple smaller segments called leaflets. These leaflets are attached to a central stem (rachis).
Let's examine each leaf:
-
Leaf 'a': This leaf has a single, continuous blade with serrated edges and a prominent midrib. There are no separate leaflets; it is one unified structure. This fits the definition of a
simple leaf.
-
Leaf 'b': This leaf is composed of multiple distinct leaflets arranged along a central stem. This is a classic example of a compound leaf (specifically, pinnately compound).
-
Leaf 'c': Like leaf 'b', this leaf is made up of several leaflets attached to a central rachis. It is also a compound leaf.
-
Leaf 'd': This leaf has a highly divided, feathery appearance, with many small leaflets branching off a central stem. This is another type of compound leaf (pinnately compound, possibly bipinnate).
Therefore, the only leaf that meets the criteria for a simple leaf is leaf 'a'.
The correct answer is
a.
