Current Question (ID: 12120)

Question:

Mark the incorrect statement (with respect to gymnosperms)

Options:

1. Sequoia is one of the tallest tree species
2. Dimorphic roots, stem and leaves in pinus
3. Generally tap roots are present
4. Palmately compound leaves in Cycas

Solution:

Cycas, which is a genus of gymnosperms, has pinnately compound leaves, not palmately compound leaves. Palmately compound leaves are typically found in some angiosperms, where the leaflets radiate from a common point at the tip of the petiole like the fingers of a hand. Gymnosperms, including species like Sequoia, Pinus, and Cycas, generally have simple leaves or pinnately compound leaves with leaflets arranged along a central axis, not palmately compound leaves. Therefore, statement 4 is incorrect. Statements 1, 2, and 3 are correct as Sequoia is known for being one of the tallest tree species, Pinus exhibits dimorphic roots, stems, and leaves, and gymnosperms generally have tap roots.
