Specialized structures that perform cell functions are organelles.
What are cell organelles?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
An organelle is a particular sort of cell structure. Organelles come in many different varieties. Vesicles are another name for organelles in a cell. They actually serve a purpose that is crucial since all of the processes in a cell must be compartmentalized. Therefore, a membrane is required to surround the processes inside a cell that produce diverse products. Organelles are therefore all membrane-bound in reality. They also distinguish between one function and another. So, for instance, the lysosome breaks down large molecules to make small molecules, while the mitochondrion produces energy by breaking down large molecules.
They must be divided up since the lysosome requires an acidic pH and the mitochondrion relies on all of its pathways, proteins, and enzymes to convert one chemical to another. Additionally, none of the functions would be created if those two substances were combined.

D because the others harm the bird instead of helping
The concept would be crystallization. As magma cools inside or outside of the earth it crystallizes into an igneous rock. Intrusive (formed inside crust) igneous rocks are typically more course grained and contain many different noticeable minerals (for example, granite). Extrusive (formed outside) igneous rocks are typically more porous and are more fine grained then intrusive rocks (example, obsidian).
The basics would be that you'd need to find out if they could exchange genetic information. If not, they couldn't be considered part of one species. Set-up 2 artificial environments so both groups would produce pollen at the same time. Fertilise both plants with the other's pollen. Then fertilise the plants with pollen from their own group.
Count the number of offspring each plant produces.
If the plants which were fertilised by the opposite group produce offspring, they are of the same species. You can then take this further if they are of the same species by analysing if there is any difference between the number (and health) of offspring produced by the crossed progeny and by the pure progeny. You'd have to take into account that some of them would want to grow at different times, so a study of the progeny from their first sprout until death (whilst emulating the seasons in your ideal controlled environment). Their success could then be compared to that of the pure-bred individuals.
Make sure to repeat this a few times, or have a number of plants to make sure your results are accurate.
Or if you couldn't do the controlled environment thing, just keep some pollen one year and use it to fertilise the other group.
I'd also put a hypothesis in there somewhere too.
The independent variable would be the number of plants pollinated. The dependant variable would be the number of progeny (offspring) produced.
Answer:
more exposure to sunlight and therefore increase photosynthetic production
