4. What are the types of nutrition intake?
In terms of nutrition, there are two options: Autotrophic - Plants are main producers because of their autotrophic feeding. Nourishment is made by plants using light, carbon dioxide, and water to synthesize their food. A heterotroph is an animal or human who relies on plants for nourishment. Chemistry and chemicals essential for plants to develop as well as their supply from the outside is known as Plant Nutrition. A lack of this nutrient would cause the plant to die.
5. How do plants get their nutrition intake?
Photosynthesis, the process through which plants get their nutrition, happens in the leaves. A plant's leaves include veins that allow nutrients and hormones to flow throughout the leaf's cells. In photosynthesis the plants and other organisms transform light energy into chemical energy. This energy is then released to power the organism's activities through cellular respiration. It is an integral part of the plant’s life cycle and its survival depends on its efficient functioning.
6. Do plants feel pain?
Plants, unlike humans and other animals, lack nociceptors, which are receptors that are designed to respond to pain. They also don't have brains, therefore they don't have the gear to convert those impulses into genuine experiences. This is why plants lack the ability to experience pain. Plants, like all living things, desire to stay alive, and study has shown that when particular plants are cut, they make a scream-like sound. There are multiple theories regarding this.
7. What are the stages of photosynthesis?
The photosynthetic process in plants may be divided into four phases, each happening in a specific region of the chloroplast: (1) light absorption, (2) electron transport leading to the reduction of NADP+ to NADPH, (3) ATP production, and (4) CO2 conversion to carbohydrates (carbon fixation). This is a very crucial phenomenon and the plant’s survival depends on its efficient functioning. It also ensures the continuation of the plant’s vital role in nutrition production.

8. What do you mean by chlorophyll?
The chemical that gives plants their green hue is chlorophyll. During the biological process known as photosynthesis, it aids plants in absorbing energy and obtaining nutrients from sunlight. Many green foods contain chlorophyll, and some individuals take it as a supplement or apply it topically. It is a very crucial component of green plants and forms the backbone of their nutrition intake and food processing. It is the guiding factor behind photosynthesis in plants.
