Detailed explanation-1: -4-In samaras, the pericarp surrounding the seed extends out in the form of a wing or membrane, which aids in dispersal (Fig. 8.17). In maples, samaras are produced in pairs, but in ashes, elms, and the tree of heaven, they are produced singly. 5-The twin fruit called a schizocarp (Fig.

Detailed explanation-2: -A samara is a type of fruit surrounding a seed in which a flattened wing of papery tissue develops, allowing the wind to carry the seed away from the parent plant. This helps trees like maples and ash disperse their seeds so they can thrive and grow.

Detailed explanation-3: -fruit development The fruit wall, or pericarp, is divided into three regions: the inner layer, or endocarp; the middle layer, or mesocarp; and the outer layer, or exocarp.

Detailed explanation-4: -The pericarp (fruit coat) surrounds the entire seed and consists of two portions, the outer pericarp and inner pericarp. The outer pericarp has the following layers: the epidermis (epicarp), the hypodermis, and the innermost layer, called the remnants of thin-walled cells.
