Answer 1

Difference between pinnately compound leaf and palmately compound leaf:

Pinnately compound leaf:

• Leaflets are arranged on either side of a common axis called rachis
• Resembles the structure of a feather
• Leaflets do not arise from a single point
• Example: Neem, Rose

Palmately compound leaf:

• Leaflets arise from a single point at the tip of the petiole
• Resembles the fingers of a palm
• Rachis is absent
• Example: Silk cotton, Lupin

Final Answer:

Pinnately compound leaves have leaflets arranged along a rachis, whereas palmately compound leaves have leaflets arising from a single point.
