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 ...
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 ...
One of the outcomes of plant reproduction is the generation of seeds, spores, and fruits [13] that allow plants to move to new locations or new habitats. [14] Plants do not have nervous systems or any will for their actions. Even so, scientists are able to observe mechanisms that help their offspring thrive as they grow.
Pumpkins just keep getting bigger and bigger each year, and scientists and farmers don't even know how large they can get. You're not imagining it. Pumpkins just keep getting bigger and bigger ...
The English word squash is derived from a Massachusett word, variously transcribed as askętasquash, [10] ashk8tasqash, or, in the closely related Narragansett language, askútasquash.) [11] Researchers have noted that the term pumpkin and related terms like ayote and calabaza are applied to a range of winter squash with varying size and shape ...

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.
