Answer:
Chloroplasts absorb sunlight and use it in conjunction with water and carbon dioxide gas to produce food for the plant. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis.

Embracing the complexity of the microbiome means doing away with pat conceptions of its function.
Your body is a habitat to trillions of microscopic organisms known, collectively, as your microbiome. Today, the microbiome is one of the hottest areas of biological research, and for good reason. This body-wide ecosystem not only adapts to our diets, lifestyles, and medications, it's also been shown hold sway over our health. The implications for personalized medicine seem clear – the more we understand about the microbiome, the more we can do to condition, or control it to our liking.
But to what end? To shepherd one's microbiome toward some idealized state of healthiness would first require that such a state exists. What does such a state look like? Nobody knows, because an ideal microbiome is almost certainly an illusion. As science writer Ed Yong opines in today's New York Times, contrary to claims by the probiotic industry and the booming genre of microbiome diet books, any system as "complex, varied, ever changing and context-dependent" as the microbiome will, by its very nature, resist easy categorization:
The microbiome is the sum of our experiences throughout our lives: the genes we inherited, the drugs we took, the food we ate, the hands we shook. It is unlikely to yield one-size-fits-all solutions to modern maladies.
We cling to the desire for simple panaceas that will bestow good health with minimal effort. But biology is rarely that charitable. So we need to learn how tweaking our diets, lifestyles and environments can nudge and shape the ecosystems in our bodies. And we need ways of regularly monitoring a person's microbiome to understand how its members flicker over time, and whether certain communities are more steadfast than others.

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.
More differences between prokaryotic and eukaryotic transcription:
• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,
• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).
• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.
• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.
