Generally, the fruit consists of a wall or pericarp and seeds. The pericarp may be dry or fleshy. When pericarp is thick and fleshy, it is differentiated into the outer epicarp, the middle mesocarp and the inner endocarp.
Which of the following statements about the fruit are correct? S1: The pericarp of a fruit, which is the fruit wall, can be either dry or fleshy. S2: If a fruit develops without fertilisation of the ovary, it is termed a parthenocarpic fruit and usually lacks viable seeds. S3: Ovules consistently mature into seeds, and this process is essential for the formation of all types of fruits, including parthenocarpic ones. S4: In drupes like mango, the mesocarp is fleshy and edible, while in coconut, the mesocarp is fibrous. S5: The epicarp, mesocarp, and endocarp are always distinctly differentiated in all fruits, regardless of whether the pericarp is dry or fleshy.
