Animals do not always deliver pollen grains to recipient flowers of the same species. Interspecific pollen transfer (IPT) is a potential force in several contexts, including (1) the evolution of isolating barriers in speciation, (2) the interplay between competition/facilitation when co-occurring plant species share pollinators, (3) the potential physiological effects of allelopathic pollen on female reproductive success, (4) the loss of fitness through male function, and (5) the possible role in species interactions that govern plant community assembly or disassembly, including invasive species and phenological shifts. Over the last 40 years, such phenomena have received attention in scattered studies, but there has been a recent resurgence, as a number of young investigators have converged—from all of the above directions—to identify IPT as a primary object of study. The time is ripe for a symposium that will critically look backward and forward. Looking backward will help place current questions in a historical context and revise some incorrect or superficial impressions that show signs of taking root. Looking forward will help establish an agenda for further research. Expected participants include: Nathan Muchhala, Gerardo Arceo-Gomez, Robin Hopkins, Tia-Lynn Ashman, Shuang-Quan Huang, James Thomson

 Watch a video about photosynthesis.   Find out why leaves are green, and the role of chlorophyll.

In addition to this the components of chloroplast participate in several regulatory functions of the cell as well as in photorespiration.

The role of chloroplasts in photosynthesis has been illustrated below followed by a description of the roles of different components of chloroplasts


chloroplast development may play a role in ..

Flow of Energy  Thoroughly describe..... How does photosynthesis play a role in the flow of energy on Earth?

Plants, being the only producers, have a crucial role to play in any food chain.

Photosynthesis is vital to facilitate the process of respiration in both, humans and animals, as our oxygen requirements are fulfilled by the oxygen which is produced during this process.

The Amazon rainforest, alone, produces 20-30 percent of the total oxygen on the planet.

The fact is that photosynthesis plays a crucial role in making the Earth the only planet with life.

and they play a vital important role in photosynthesis

Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis

Fruits are unique to flowering plants and play acentral role in seed maturation and dispersal. Molecular dissection of fruit physiologyand quality regulation has received considerable interest because of thebiological and dietary significance of fruit. The changes in fruit quality attributes,such as color, flavor, aroma and texture, represent complex physiological andbiochemical processes during fruit development and ripening. Considerableprogress has been made in our understanding of the biochemical and molecularbasis of fruit quality formation and regulation. The important roles of transcriptionalfactor networks and phytohormone signaling pathways have been established inthese processes. This symposium is aimed to gather the global scientists in thearea of fruit physiology and quality regulation to emphasize the most importantrecent findings and to discuss the future directions in this field.

Flavonoids are widely distributed in higher plants and synthesized via the phenylpropanoid pathway. They play important roles in oxidative stress, UV filtration, symbiotic nitrogen fixation and floral pigmentation. For human beings, flavonoids have a broad range of biological and pharmacological activities. With the increase in living standards, people are becoming more and more interested in healthy food. Flavonoid components and their biosynthetic pathways differ in different plant species. Thus, it is a big challenge to identify specialized flavonoid components and elucidate their biosynthetic pathways. In addition, regulatory mechanisms underlying flavonoid biosynthesis are also important for improving plant productivity and food quality. The world leading scientists in this field will be invited to present their state-of-the-art advances in the study of flavonoid biosynthesis and regulatory mechanisms. Some speakers will be directly selected from the submitted abstracts through the congress website. Here, we sincerely invite you to participate in this symposium and look forward to meeting you in Shenzhen.

2.I can explain the role that pigments play in photosynthesis

So it fell to a Dutchman, (left), who was court physician to the Austrian empress, to make the next major contribution to the mechanism of photosynthesis. He had heard of Priestley's experiments, and a few years later spent a summer near London doing over 500 experiments, in which he discovered that light plays a major role in photosynthesis.

The main function of the chloroplast is photosynthesis

This ability is conferred through the presence of specialized organelles called chloroplasts, commonly referred to as the 'kitchens' of plant cells.

Chloroplasts are plastids that contain a network of membranes embedded into a liquid matrix, and harbor the photosynthetic pigment called chlorophyll.

Describe the roles of photosynthesis and respiration in ..

Tiny vesicles bud off from the inner membrane of the chloroplast, and assemble to form the tubules of peripheral reticulum.


Chloroplasts are the site for photosynthesis, which comprises a set of light-dependent and light-independent reactions to harness solar energy and convert it into chemical energy.

the roles of photosynthesis and respiration in ecosystems.

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

What role does a leaf play in a plant? | Yahoo Answers

Large conductance SV/TPC1 channels are ubiquitously and abundantly expressed in the vacuolar membranes of higher plants. They are unique established Ca2+-permeable channels in vacuoles, but their activity is strongly negatively controlled, so that they were believed to be inactive or to act only locally. Recent evidence suggests the key role of SV/TPC1 channels in the long-distance Ca2+ signalling.
