Non-green plants carry out photosynthesis? Yes or no? Give reason?
Answers
Answer:
no
Explanation:
becouse they do not have chlorophyll
Answer:
A primary difference between plants and animals is the plant’s ability to manufacture its food.
Photosynthesis is a process where carbon dioxide from the air and water from the soil react with the sun’s energy to form photosynthates (sugars, starches, carbohydrates, and proteins) and release oxygen as a byproduct.
Every green leaf in the world is utilising the most of the solar energy along with water and carbon dioxide to produce food. The carbohydrates manufactured in this process forms the foundation of the food chain. Plants and some photosynthetic bacteria & algae are the only ‘producers’ of food. All other living organisms are ‘consumers,’ feeding directly or indirectly on the food produced in photosynthesis. This process is also the primary source of oxygen that most living creatures need to breathe.
Plant leaves have three primary classes of pigments: chlorophyll, carotenoids and anthocyanins.
Most plants are green. This green colour is due to the presence of a pigment called chlorophyll that is found in the leaves. Photosynthesis occurs in these green leaves. These pigments capture light energy from the sun and start the process of photosynthesis.
Some ornamental plants have leaves that aren’t green. Rather, they have purple, red, yellow or variegated leaves. It makes us think that how do these plants survive without the production of food.
The fact to this thought is
– Firstly the plants with purple or red leaves do have chlorophyll but in a lesser amount. The green colour is masked by the other pigment like anthocyanin or carotenoid. Hence the leaves are purple or red. The process of photosynthesis is being carried out underneath the leaves.
– Secondly, some plants have white leaves as visible to our naked eyes. It is because of the reflection of light from leaves at a particular angle which makes them appear white. This trick of reflection hides all the chlorophyll enabling the photosynthesis.
– The third fact is that some coloured leaves do not have chlorophyll and are dependent on the other green leaves of the plants which are performing photosynthesis.
– Lastly plants called parasitic plants are with coloured leaves. They do not have chlorophyll. They take up the sugars from other plants and do not perform photosynthesis. These plants rely on other plants and take up the sugar and water through roots. Hydnora africana is a parasitic plant.
So it can be concluded that almost all plants have chlorophyll either masked or visible that is needed for photosynthesis except parasitic plants.
