I know a genetics professor that found the reason for the juvenile leaf into a adult, a gene (151) in the RNA. He is presently working on what factor that promotes this to happen.

The minerals will stay behind. They are too heavy to be transported via the vacuoles of MOST, and most must be stressed when dealing with plants, plants during transpiration. Though the water-soluble compounds- including the volatile compounds mentioned like terpenes and even flavonoids will and can exit during transpiration. Terpenes are not bad for humans, ...

Fertilizer on tomatoes wouldn't make sense. Tomatoes are up above the soil, and fertilizer is usually applied to the soil before the plants sprout, but I've never seen an industrial tomato farm, so maybe they do spray fertilizer afterwards, but I would think pesticides or herbicides would be more likely. Fertilizer on carrots would make more sense, since ...

The rhizosphere is the narrow region of soil that is directly influenced by root secretions and associated soil microorganisms (wiki) And endorrhiza (also termed Endomycorrhiza, AMS or AM) is a special case of the mycorrhiza, a mutualistic relationship between fungi and plant roots, where the fungus cells are stored within the root and not on its surface.

You could use this key to the genus. The differences between both species should become obvious when tracing back the decision tree. It seems that they can be distinguished mainly by the leaf size/shape of adult plants.

It will depend a bit on the specimen of tree / plant that is doing the transpiration. Minerals will typically stay behind during evaporation, but volatile compounds (think the minty smell of Eucalyptus) would evaporate at the same time as the water, and might condense (in some concentration) at the same time as well; this will depend a bit on the temperature ...

In nature, species compete for resources like water, light, nutrients, etc. and need to find 'their place' in this struggle. According to niche theory, every species occupies a certain spot in the multidimensional niche space (the dimensions describe the number of environmental factors) where it performs better than any other species. If there would not be ...

The plant looks like Pokeweed (Phytolacca americana) to me, a common "weed" in the U.S.

As 3cat already stated, the terms actually refer to the pollinators. While solitary and social describe the behavioural traits (see this wikipedia article), diploid and haplodiploid give information about the chromosome number of the pollinators (see here and here). The descriptions in the article depict different combinations of both characteristics.

It reminds me of the smooth-barked Australian gum trees / eucalyptus, like a salmon gum, ghost gum, etc. Although there are no squirrels in Australia :) This photo of a Salmon Gum is from http://www.fpc.wa.gov.au/content_migration/plantations/species/arid/salmon_gum.aspx

I got to thinking that there must be a distinction between grain and the germ. The grain must die in order for the germ to come alive. I am confident that the germ will not grow so long as the grain is alive. It is through the process of its dying and acquiring moisture from the earth, that the grain converts to sugar which supports the germ and enables it ...

Is the necessary that stamens have two microsporangia per theca? No. Many species in Cryptocarya group of Lauraceae have microsporangia that have fused such that they have only two microsporangia instead of the typical four (Rohwer et al. 2014). I interpret their description as saying that the microsporangia within a theca but it's not clearly stated as ...

This looks pretty much like Buddleja davidii to me. They are available in a range of different colors, see this image from the Wikipedia:

Howe and Smallwood (1982) provide a nice review of the many methods of seed dispersal that have evolved in plants. The review is broad but they do have a section on frugivory. They highlight hypotheses developed by McKey, and Howe and Estabrook (see Howe and Smallwood for citations) that suggest plants may use one of two strategies. One strategy is the ...

Cattles actually hate shrubs which are very tough to break and tasteless(for a cow). Some plants they won't touch are: Lantana urticoides (West Indian shrub verbena), Malvaviscus arboreus var.drummondii (wax mallow) Rhus copallinum (winged sumac) Viburnum acerifolium (mapleleaf viburnum). Morella cerifera (wax myrtle) Ilex vomitoria (yaupon). Source: ...

How are you defining fruits? Because if you count any seed body of a flowering plant, you must include several items commonly described as vegetables, including pumpkins, zucchini, squash, cucumber, peppers, etc. And there are other colors of fruit, such as blue berries. These all serve similar functions for the plant, something eats the fruit, then deposits ...

Dried grains are very mostly viable means they are in a dormant state until and unless suitable condition are provided. More dried it will be viable for longer. In fact there are seed found in Siberia which are ~32,000 years ans still viable. Courtesy: National Geographic Source: US Emergency Supply: Introduction to Seed Viability

This question is related to the question: Why are some things transparent and others opaque? Being able to see something requires that it is opaque and that sufficient light illuminates it. UV and shorter wavelengths are not as prevalent as visible light on earth. The world would appear too dark to see if we used UV and shorter wavelengths. This is ...

Please check and tell me and how do I go about the co-transformation of rice using Agrobacterium starting from E.coli

According to this link from Purdue, the seed of the answer is this: The herbicide is used to kill broadleaf weeds, which are dicots, while monocot grasses, such as sorghum and corn, are more resistant. That's because grasses inactivate 2,4-D inside the plant, while broadleaf dicots do not. But on the other hand, Song 2014 has this to say about 2,4-D: ...
