We also have to be careful when studying green plants because in the light the green parts of these plants carry out photosynthesis as well as respiration.

How do non-green colored leaves in a plant photosynthesize?
The roots of a plant also need oxygen which they obtain from the air spaces in the soil. If you give too much water to a plant in a pot you could kill the roots by drowning them! Plants, such as rice, which normally grow in wet soil often have air spaces in their roots. This is so that they can carry air from the atmosphere down to the root tips to be able to respire under water.
Photosynthesis occurs inside chloroplasts. Chloroplasts contain chlorophyll, a green pigment found inside the thylakoid membranes. These chlorophyll molecules are arranged in groups called photosystems. There are two types of photosystems, Photosystem II and Photosystem I. When a chlorophyll molecule absorbs light, the energy from this light raises an electron within the chlorophyll molecule to a higher energy state. The chlorophyll molecule is then said to be photoactivated. Excited electron anywhere within the photosystem are then passed on from one chlorophyll molecule to the next until they reach a special chlorophyll molecule at the reaction centre of the photosystem. This special chlorophyll molecule then passes on the excited electron to a chain of electron carriers.
Is a mushroom a non-green plant?
An absorption spectrum is a graph showing the percentage of light absorbed by pigments within the chloroplast, for each wavelength of light. An example is the absorption spectrum of chlorophyll a and b. The best absorption is seen with violet-blue light. There is also good absorption with red-orange light. However most of the green-yellow light is reflected and therefore not absorbed. This wavelength of light shows the least absorption.
As we can see, there is a close relationship between the action spectrum and absorption spectrum of photosynthesis. There are many different types of photosynthetic pigments which will absorb light best at different wavelengths. However the most abundant photosynthetic pigment in plants is chlorophyll and therefore the rate of photosynthesis will be the greatest at wavelengths of light best absorbed by chlorophyll (400nm-525nm corresponding to violet-blue light). Very little light is absorbed by chlorophyll at wavelengths of light between 525nm and 625 (green-yellow light) so the rate of photosynthesis will be the least within this range. However, there are other pigments that are able to absorb green-yellow light such as carotene. Even though these are present in small amounts they allow a low rate of photosynthesis to occur at wavelengths of light that chlorophyll cannot absorb.

this observation was due to the usage of carbon dioxide in the solution by the leaf turning the calcium carbonate back to calcium hydroxide, thus, the photosynthesis occurs on nongreen plants but the rate of photosynthesis is lower than the rate of green plants.
but the vegetative parts of the plant are as green as anything
So why would cacti evolve these two unusual features of green stems and non-photosynthetic stabby leaves? Well, these combination of traits are adaptations to dry and resource-poor environments. Big and flat leaves have lots of surface area which is typically a good thing from a plant’s perspective as it captures lots of sunlight for photosynthesis. But many plants have more sunlight than they can handle and more photosynthetic area means more water loss. All photosynthesis requires gas exchange, carbon dioxide in and oxygen and water vapor out. So for plants in water-limited and very sunny environments, like deserts, adaptations that limit photosynthetic area (and thus limit water-losing gas exchange) are likely to be advantageous and selected for.
Non- green plants are those plants which do not have ..
Photosynthesis does the opposite of respiration. Carbon dioxide is absorbed and oxygen is produced. In order to study respiration in green plants we must block out the light, because although green plants respire all the time they only photosynthesize in the light.

The >1500 cactus species all live in the Americas (well except one in Africa, probably dispersed there by birds) and mostly in arid environments. However, there are also many cacti that live in the tropical rainforests of Central and South America. At first this doesn’t make sense why a arid-adapted group would have a center of diversity in some of the world’s wettest habitats, until you look at the micro-habitats they live in, namely, up in the forest canopy. Rainforest cacti are almost all ephiphytes, meaning they grow on other plants, normally the branches of large trees. From plants’ perspective these environments are actually very dry, it is hot, there is no soil to hold water, and airflow from all directions desiccates. So the elegant adaptation that cacti evolved in the deserts gave them an advantage as tropical ephiphytes and when they arrived in these new habitats they thrived and diversified.
