Oct 31, 2015 · All fruits come from flowers, but not all flowers become fruits. Fruits are typically derived from the ovaries of a flower and contain seeds. This means all parts of a plant that flower (including most culinary nuts and berries) are “fruits” and all non-flowering parts of plants are “vegetables”. How we classify a food often depends on ...

Flowering plants are all around us: they line our streets, fill our gardens, and decorate our homes. In fact, flowering plants are currently the most diverse plant group on Earth. Many familiar trees, such as oaks and maples, are flowering plants. Flowers are not only beautiful and attractive to insects and humans, but they are also vital to the pl...
One of the main functions of a fruit is to spread the seeds and allow the plant to reproduce. Therefore, all flowering plants produce fruit, regardless of whether the fruit is edible, sweet, or soft. This means that, although we call peppers and cucumbers vegetables, they are technically fruits (Figure 2). Acorns, maple keys, and the outside of sun...
Every single fruit, regardless of whether it looks like the kind of fruit we are used to seeing in the produce section, has three distinct layers—the exocarpOutermost layer of the fruit. Usually in direct contact with the environment, provides the texture of the fruit. (outside), mesocarpMiddle layer of the fruit, in between the exocarp and the end...
Fleshy fruits have high water content in the pericarp, and a fleshy mesocarp once they are mature. This means that fleshy fruits are juicier than dry fruits. The group of fleshy fruits includes many of the fruits that you may find in the grocery store, and many sweet fruits, such as peaches and apples. Pomegranates, although we eat the seed and not...
Dry fruits are hard and dry when they are fully mature (Figures 3A–C). The pericarp of dry fruits still has three layers—exocarp, mesocarp, and endocarp—but compared with fleshy fruits, they are thinner and do not have as much water. Sometimes the pericarp is in direct contact with the seed, making it hard to tell the fruit apart from the seed. Mos...
In addition to “dry” and “fleshy,” fruits can be further described by their structures: simple, aggregate, or multiple. A simple fruit develops from one single ovary, such as a peach or a tomato (Figure 2D). An aggregate fruit forms from multiple ovaries in a single flower. Strawberries and blackberries are examples of aggregate fruits (Figure 3D)....
Fruits are not the only parts of the plants that we eat. The term vegetable can be used to refer to other edible parts of the plant—leaves, stems, shoots, and roots. A carrot, for example, is a vegetable, because the part of the plant that we eat is the root. Broccoli is made of multiple floral buds, and is also traditionally known as a vegetable. ...
If a fruit’s purpose is to house and disperse seeds, then why do we call seedless fruits like grapes, oranges, and watermelons fruits? Although they do not contain seeds, these structures are still considered fruits, because they develop from the carpel of the flower through a series of transformations. Seedless fruit can come about due to a proces...
Fruits are all around us, sometimes requiring close observation in order to be discovered. The next time you are eating a salad, look a little bit closer to see which fruits are in the bowl. The next time you hold a strawberry, feel the outside, and see if you can count how many fruits you are about to eat! The next time you go outside, open a mapl...

Fruits, Flowers, and Seeds. Flowering plants grow in a wide variety of habitats and environments. They can go from germination of a seed to a mature plant producing new seeds in as little as a month or as long as 150 years. Plants that complete their life cycle in a single season are called annuals while biennials take two years, and perennials ...
Mar 3, 2020 · Plants make fruits to lure in animals to disperse their seeds. Animals eat the nutritious fruit, and then drop the seeds on the ground. What we call vegetables are just different parts of the plant—typically the leaves, stem or roots. These parts are packed with starch that the plant makes through photosynthesis.

May 28, 2015 · Fruit is found on all angiosperm plants and are produced following the pollination of flowers. They come in a huge variety of colors, shapes and sizes and only a tiny fraction of all fruits are commonly eaten by humans. They are the product of swollen ovaries and other floral parts inside which the seeds of the plant are grown and stored.
