It's a type of begonia. With 1800 species in the genus, it's hard to say which it is, but the leaves which seem palmate would place it in the aconitifolia species. Your leaves don't appear to be variegated, and your flower is deeper pink, but it's the same flower species.


This can be a result of a somatic mutation, especially if the other flowers on the same plant don't have the same color pattern. Somatic mutations are not inherited for parent organisms but occur spontaneously in one of the cells in the body. If that cell then proliferates all of its descendants will have the mutation and new phenotype associated with it. ...


A symbiotic relationship is entirely unrelated to the genetic origins of the participating organisms. Symbiosis only requires that the organisms interact in a manner that benefits both parties. There is nothing that requires any genetic similarity between symbiotic organisms. You may happen to find that particular species of trees and mushrooms do indeed ...


No. (Unless you are an undergraduate student at a debating society trying to be clever). Evidence: If you go to the TreeGenes site and examine those tree genomes that have been sequenced you won’t find any fungal chromosome sequences. (And vice versa.) Reason: Although trees and mushrooms may develop symbiotic relationships they are independently viable (...


The word genome gets tossed around a lot but it really is a technical term. The genome is the total heritable genetic information carried by a cell or organism. It is possible for one organism to incorporate the DNA of another into its genome, for example, extrachromosomal plasmid DNA found in E-coli, however in this case its not like the tree is ...


Should be a Papaya, thus a fruit, an outline of your geographical location would be helpful to determine it.


All plants have sieve cells, but not all plants have sieve tube elements because they evolved after the plant family tree had started to branch. Only angiosperms have sieve tube elements. Sieve tube elements are more specialized for their job as transport cells, and can transport more nutrients faster than sieve cells. During their development, the ...
