The phloem is a system of cells that transports sugars produced by plant leaves down the stem to other leaves, fruits and roots. If aphids take too much, the plant starts to suffer. This is why aphids are sometimes "pests" of ...

In botany and horticulture, parthenocarpy is the natural or artificially induced production of fruit without fertilisation of ovules, which makes the fruit seedless. The phenomenon has been observed since ancient times but was first scientifically described by German botanist Fritz Noll in 1902. Stenospermocarpy may also produce apparently seedless fruit, but the seeds are actually aborted while they are still small. Parthenocarpy (or stenospermocarpy) occasionally occurs as a mutati…
