There are two main types of fruits - simple fruits which develop from a single ovary, and aggregate/multiple fruits which develop from multiple ovaries or flowers. Simple fruits can be fleshy like berries, drupes, and pomes, or dry like legumes, follicles, capsules, achenes, and nuts. Fleshy fruits like berries become soft and juicy, while a drupe has a hard stone or pit surrounding its seed. A pome is an accessory fruit with multiple carpels fused together. Dry fruits either open at maturity to release seeds like legumes and follicles, or stay closed like achenes and nuts.
