If asked to describe a fruit, most people would immediately turn their minds to the produce isle at the grocery story.\u00a0 This is not the case for a botanist.\u00a0 As the seed bearing part of a plant consisting of a mature ovary and sometimes additional flower parts, the fruit is certainly one of the most important structures when it comes to plant reproduction and biogeography.\u00a0 Over time, flowering plants have evolved to form different types of fruit to account for different seed dispersal strategies.\u00a0 Fruit can be fleshy or dry, and there is considerable variability within each of these types.\u00a0 In this article, we will look at the three types of fleshy fruits.
\nWhen you think of a fleshy fruit, you may think of something like a cherry (Prunus<\/em> spp.).\u00a0 A cherry is a good example of a drupe<\/strong>, which is a fleshy fruit that has a single seed per carpel (a carpel is a chamber within the ovary) and a stony endocarp (inner layer) that tightly surrounds the seed.\u00a0\u00a0 Using the example of a cherry, the ovary has a single carpel with a single seed, and when the fruit forms, the \u201cpit\u201d is the stony inner layer of the fruit; the seed is inside of this stony layer.<\/p>\n

\"Tomato\"<\/a>

You\u2019ve probably heard the argument that a tomato (Lycopersicon<\/em> spp.) is a fruit.\u00a0 Well sure it is\u2026 it is the matured ovary and contains the seeds!\u00a0 No one would argue that a tomato is fleshy.\u00a0 If you cut a tomato in half, you will see that it has several carpels, but instead of having just one seed per carpel, tomatoes have many seeds per carpel.\u00a0 In addition, the inner layer of the fruit wall is not stony but rather is also fleshy.\u00a0 These are the characteristics that lead to the tomato being categorized as a berry<\/strong>.When you think of a fleshy fruit, you may think of something like a cherry (Prunus<\/em> spp.).\u00a0 A cherry is a good example of a drupe<\/strong>, which is a fleshy fruit that has a single seed per carpel (a carpel is a chamber within the ovary) and a stony endocarp (inner layer) that tightly surrounds the seed.\u00a0\u00a0 Using the example of a cherry, the ovary has a single carpel with a single seed, and when the fruit forms, the \u201cpit\u201d is the stony inner layer of the fruit; the seed is inside of this stony layer.<\/p>\n

The third type of fleshy fruit is represented by the apple (Malus<\/em> spp.).\u00a0 In the apple, the compound ovary and the hypanthium (the fused bases of the sepals, petals, and stamens) together form the fruit, which is known as a pome<\/strong>.\u00a0 The endocarp forms the core of the apple, within which the ovary and seeds are found.\u00a0 You can often see the remains of the sepals on what we consider the bottom of the apple, opposite the stem, which is on what we consider the top of the apple.\u00a0 Because the ovaries are located below the attachment of the floral parts, the ovaries are said to be inferior; pomes have inferior or half-inferior ovaries.<\/p>\n
