An example of multiple fruits are the fig, mulberry, and the pineapple. [1] Simple fruits are formed from a single ovary and may contain one or many seeds. They can be either fleshy or dry. In fleshy fruit, during development, the pericarp and other accessory structures become the fleshy portion of the fruit. [2]
Multiple fruits are not botanical berries. Multiple fruits are the fruits of two or more multiple flowers that are merged or packed closely together. [21] The mulberry is a berry-like example of a multiple fruit; it develops from a cluster of tiny separate flowers that become compressed as they develop into fruit. [22]
Fruits in which part or all of the pericarp is fleshy at maturity are termed fleshy simple fruits. Types of fleshy simple fruits, (with examples) include: Berry – the berry is the most common type of fleshy fruit. The entire outer layer of the ovary wall ripens into a potentially edible "pericarp", (see below).

A fruit tree is a tree which bears fruit that is consumed or used by animals and humans — all trees that are flowering plants produce fruit, which are the ripened ovaries of flowers containing one or more seeds.
Regions with characteristic vegetation types and dominant plants as well as similar abiotic and biotic factors, climate, and geography make up biomes like tundra or tropical rainforest. [108] Herbivores eat plants, but plants can defend themselves and some species are parasitic or even carnivorous.
Factors of the physical or abiotic environment include temperature, water, light, carbon dioxide, and nutrients in the soil. [62] Biotic factors that affect plant growth include crowding, grazing, beneficial symbiotic bacteria and fungi, and attacks by insects or plant diseases. [63] Frost and dehydration can damage or kill plants.
Plants have limited mobility and rely upon a variety of dispersal vectors to transport their propagules, including both abiotic vectors such as the wind and living vectors like birds. [14] Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time.
Crops are modified to increase their resistance to biotic and abiotic stressors such as parasites, disease, and drought as well as increase yield, nutrition, and flavour. [27] Additionally, CRISPR has been used to edit undesirable traits, for example, reducing the browning and production of toxic and bitter substances of potatoes.
