What Do Plants Do: The Fascinating World of Photosynthesis
What Do Plants Do?
Plants have various essential functions to survive and thrive.
They make their own food through photosynthesis, using water, carbon dioxide, and sunlight to produce sugar molecules.
These sugar molecules are used for respiration and building other plant parts.
Additionally, plants require additional chemicals from the soil like nitrates and phosphates.
They can recognize the time of the year by measuring the amount of daylight.
Based on the duration and quality of light, plants adjust their growth, such as growing taller if shaded.
They also have defense mechanisms, including producing chemicals to deter insects, warning neighboring plants of danger, releasing chemicals to combat fungal diseases, and sealing off damaged plant parts.
In summary, plants perform daily functions related to food production, mineral extraction, season determination, availability of light, and protection from animals.

Did You Know?
1. Did you know that some plants give off chemical signals to attract predatory animals? These plants release certain scents or hormones to lure insects or bigger animals that feed on the pests, essentially acting like a natural pest control system.
2. It is fascinating to discover that plants communicate with each other through underground networks of fungi known as mycorrhizae. These intricate networks facilitate the exchange of nutrients and information between plants, allowing them to share resources and even warn each other about potential threats.
3. Venus flytraps are known for their carnivorous nature, but did you know that they actually rely on lightning-fast reflexes to capture their prey? When an unsuspecting insect comes in contact with the trigger hairs on the plant’s leaves, it causes an electric signal that prompts the Venus flytrap to snap shut, ensnaring its meal.
4. Some plants have developed remarkable adaptive survival strategies. Take the Saguaro cactus, for example, which can store up to 200 gallons of water and expand like an accordion when it rains, allowing it to endure long periods of drought.
5. There is a parasitic plant known as the dodder that lacks leaves, roots, and even the ability to produce its own food. Instead, this plant attaches itself to a host plant and drains its nutrients, essentially acting as a botanical vampire.
Plants Need Food For Survival
Plants, like all living organisms, require food to survive. However, their method of obtaining nourishment differs significantly from that of animals. While animals rely on consuming other organisms or organic matter, plants have a unique ability to synthesize their own food.
Through a process known as photosynthesis, plants convert water and carbon dioxide into sugar molecules, providing them with the energy they need to carry out vital functions.
- Plants require food for survival.
- They use a process called photosynthesis to synthesize their own food.
- Photosynthesis involves the conversion of water and carbon dioxide into sugar molecules.
“Plants have a unique ability to synthesize their own food through photosynthesis.”
Photosynthesis: Plants’ Source of Food
Photosynthesis is the key process that allows plants to generate their own food. It occurs mainly in the leaves, where specialized cells called chloroplasts are responsible for capturing sunlight energy. These chloroplasts contain a pigment called chlorophyll, which enables plants to absorb light. As sunlight falls on the leaves, the chlorophyll molecules capture its energy and initiate the conversion of water and carbon dioxide into sugar molecules.
The process of photosynthesis can be summarized as follows:
- Plants take in water from the soil through their roots
- Plants draw carbon dioxide from the surrounding air through small pores on their leaves called stomata
- When sunlight strikes the chlorophyll molecules in the chloroplasts, a series of chemical reactions take place
- This ultimately results in the synthesis of glucose, a type of sugar that serves as the primary source of energy for the plant.
“Photosynthesis is the key process that allows plants to generate their own food.”
Essential Nutrients From Soil For Plant Growth
While sugar molecules produced during photosynthesis provide plants with energy, they also require additional nutrients to support growth and development. These essential nutrients are obtained from the soil and include minerals such as nitrates and phosphates.
Plants absorb these nutrients through their roots, where specialized cells facilitate the uptake from the soil.
Nitrates and phosphates play crucial roles in various plant functions. For example, nitrates are essential components of amino acids, which are the building blocks of proteins. Phosphates, on the other hand, are involved in energy transfer processes and play a vital role in DNA and RNA synthesis.
Without a sufficient supply of these nutrients, plants may experience stunted growth and deficiencies in various metabolic processes.
- Sugar molecules from photosynthesis provide energy to plants.
- Additional nutrients are required for growth and development.
- Essential nutrients, like nitrates and phosphates, are obtained from the soil.
- Roots absorb these nutrients with the help of specialized cells.
“Proper nutrient supply is crucial for plant development and metabolic processes.”
Plants Respond to Light and Seasonal Changes
Plants have an incredible ability to perceive and respond to their environment, particularly when it comes to light and seasonal changes. By detecting the amount of daylight, plants can recognize the time of year and make appropriate adjustments to their growth and development.
Increasing daylight hours signal the arrival of spring, a time when plants start producing flowers. This process allows for reproduction and ensures the continuity of their species. In contrast, decreasing daylight hours indicate the approach of winter. During this time, plants prepare for the harsh conditions by shedding leaves, going into dormancy, or storing energy reserves. This adaptive response ensures the survival of the plant during challenging periods.
In addition to detecting the duration of light, plants also monitor its quality. Plants can sense and respond to changes in light wavelengths and intensity. For example, when a plant is shaded by other plants, it will elongate its stem and produce larger leaves to compete for light. This mechanism ensures that plants can capture the maximum amount of light energy for photosynthesis, even in crowded environments.
- Plants can detect the amount of daylight
- They adjust their growth and development accordingly
- Increasing daylight hours signal the arrival of spring
- Decreasing daylight hours indicate the approach of winter
- Plants respond to changes in light wavelengths and intensity
- Shaded plants elongate their stems and produce larger leaves to compete for light
Plants’ Defense Mechanisms for Survival
Plants face numerous threats in their environment, including herbivores, pathogens, and unfavorable growing conditions. To protect themselves, plants have evolved a range of defense mechanisms that help them survive and thrive.
One such defense mechanism is the production of chemicals that make leaves less palatable to insects. By secreting compounds such as tannins or alkaloids, plants discourage herbivores from feeding on their leaves. Additionally, plants have the remarkable ability to communicate with neighboring plants. When a plant is under attack by herbivores, it releases chemical signals into the air to warn nearby plants of the impending danger. This allows neighboring plants to activate their own defense mechanisms in anticipation of an attack.
Plants are also equipped with ways to combat fungal diseases. When a plant detects the presence of fungal pathogens, it releases specific chemicals that can inhibit or kill the invading fungi. Furthermore, if a plant sustains physical damage, it has the unique ability to seal off the injured area. By forming a protective layer over the wound, plants prevent further damage and potential infection.
