The outer layer of a drupe is typically fleshy and surrounds the seed, providing protection and nutrients for the developing seed. Drupes are commonly found in a variety of fruits such … Read more
What is a Sieve Tube Element? A sieve tube element is a specialized type of plant cell found in the phloem tissue of vascular plants. These cells are responsible for transporting organic nutrients, such as sugars and amino acids, throughout the plant. Sieve tube elements are connected end-to-end to form sieve tubes, which are part … Read more
What is Pericarp? Pericarp is the botanical term used to describe the outermost layer of a fruit. It is the protective covering that surrounds the seeds of a fruit and is derived from the ovary wall of the flower after fertilization.
