You're not imagining it. Pumpkins just keep getting bigger and bigger each year, and scientists and farmers don't even know how large they can get.
One major difference is the totipotent nature of plant cells, allowing them to reproduce asexually much more easily than most animals. They are also capable of polyploidy – where more than two chromosome sets are inherited from the parents. This allows relatively fast bursts of evolution to occur, for example by the effect of gene duplication ...
A few types of organisms, such as many fungi and the ciliate Paramecium aurelia, [11] have more than two "sexes", called mating types. Most animals (including humans) and plants reproduce sexually. Sexually reproducing organisms have different sets of genes for every trait (called alleles). Offspring inherit one allele for each trait from each ...

Immigrants to North America began using the native pumpkins for carving, which are both readily available and much larger – making them easier to carve than turnips. [50] Not until 1837 does jack-o'-lantern appear as a term for a carved vegetable lantern, [ 52 ] and the carved pumpkin lantern association with Halloween is recorded in 1866.
Sexually reproducing animals, plants, fungi and protists are thought to have evolved from a common ancestor that was a single-celled eukaryotic species. [1] [2] [3] Sexual reproduction is widespread in eukaryotes, though a few eukaryotic species have secondarily lost the ability to reproduce sexually, such as Bdelloidea, and some plants and animals routinely reproduce asexually (by apomixis ...
This fall, learn about different types of pumpkins including heirloom varieties like Jarrahdale and Cinderella. They come in all shapes, sizes, and colors!
The three traditional modes of reproduction are: [1] Oviparity, taken to be the ancestral condition, where either unfertilised oocytes or fertilised eggs are spawned. [1] Viviparity, including any mechanism where young are born live, or where the development of the young is supported by either parent in or on any part of their body. [1]
