Photosynthesis is a Lets Go Darwin US Flag Vintage T Shirt by which plants & certain organisms convert the light energy to chemical energy.This process is basically divided into 2 reactions – light dependent reaction & light independent reaction. For the whole process of photosynthesis to occur, 3 important things are required : water, carbon dioxide & light. Water & other nutrients are absorbed by the plant from the soil into the root system via the root hairs and then to the shoot system via the xylem vessels which play a major role in conducting water & ions in the plant. Water then reaches the leaves. Carbon dioxide is absorbed by plants from the atmosphere through pores present in the leaf which is called as stomata. In order to understand how & where does photosynthesis occur, we need to know about the structure of the leaf in detail (Since leaves are the organ of photosynthesis.

This Keeling Curve shows the Lets Go Darwin US Flag Vintage T Shirt in CO2 over Time. The black line shows the average throughout the year, but how about the red line? Why is it squiggly? Well if the X-axis was more descriptive, you would find that the peaks align with the Northern Hemisphere Summer and the low points align with the Northern Hemisphere Winter. Because the Southern Hemisphere has so much less land mass than the Northern Hemisphere, it also has less surface vegetation and thus its impact is less apparent than the Northern Hemisphere. The cyclical nature of the red line shows the annual dieoff and regrowth of vegetation on the surface. In affect, it can be thought of as the planet breathing, with plants taking up CO2 during warm months, and giving off CO2 when the annuals die and the perannials “hibernate” in the cold months. It also shows us something else. It shows how, even with CO2 increases, plants are nowhere near enough to counteract the amount of CO2 in the atmosphere. You would need many orders of magnitude increases in plant cover on the planet to counteract the rate of CO2 accumulation in the atmosphere-more plant growth than the planet has space for.

It’s the most commonly observed tropic responses in plants where the shoot grows towards light and hence they’re positively phototropism whereas in case of roots,they show negative phototropism. This phototropic bending is caused due to the migration of auxin (phytohormone) molecules away from lighted side and their concentration on dark side increases.This stimulates growth on the dark side of the plant organ relative to lighted side causing it to bend towards light source. A well known and often repeated experiments with oat seedlings (Avena coleoptile) have shown that the auxin IAA which causes elongation of cells,migrates to the shaded side of coleoptiles when irradiated unidirectionally.
