The guard cells's placement surrounding the stomata is advantageous because, when they're closed in low humidity/moisture conditions, they prevent the loss of water from the leaves. When moisture levels are high, they swell and allow the stomata to open.
Examples of evolutionary adaptation include the development of camouflage to avoid predators, the evolution of a protective exoskeleton in insects, the elongation of giraffe necks to reach high leaves, and the development of antibiotic resistance in bacteria.
The only coin evolution pays in is reproductive success. Having two children who leave no offspring would not give you an advantage over having one child who leaves many offspring. Or any combination thereof. Twinning is a developmental thing of egg doubling or fraternal twins being just like siblings. So, the act of twinning would not seem to confer any more advantage in and of itself, but twins having successful offspring that drive many parental genes to fixation in a population of organism would be reproductively successful that way.
Homologs are genes that share a common evolutionary origin, meaning they are derived from a common ancestor gene. Although homologs may have diverged in structure and function over time, they often retain similar sequences or structural motifs. Studying homologous genes across different species can provide insights into their biological functions and evolutionary relationships.
Advantages of producing many small leaves include increased surface area for photosynthesis and better light capture in shady environments. However, disadvantages may include higher resource allocation to maintain multiple leaves, increased vulnerability to herbivory, and potentially higher water loss through increased leaf surface area.
Cacti have spines. Evolutionary theory is that the spines were originally leaves, but which reduced in size and form to carry out a new function, as spines, to protect the plant from predators. According to the same theory the stem of the plant became the gas exchange and the 'chlorophyll-containing' 'photosynthesis' part of the plant, thus replacing the functions formerly carried out by and through the leaves.
self pollination
what is the relation is there between the position of the buds and the position of the leaves

Flowers originated from [the] Specialization due to [and resulting from] the accumulated evolutionary Adaptations of Leaves. Ordinary leaves respire, grow and Photosynthesize.
Harder the better. Waxy leaves minimize the loss of water by transpiration
No...i dont think it's even possible! It's possible if you eat them and they are leaves of hemlock or rhubarb.
The needles are the leaves of the tree, which allow it to carry out photosynthesis and produce food
no, it is not possible for them
Yes. Cactus do not have leaves.

Why certainly.
yes it is..
