Most plants contain a special colored chemical or pigment called chlorophyll that is used in photosynthesis. Chlorophyll is what absorbs the sun’s energy and turns it into chemical energy.

Darker colors tend to absorb more energy from the sun than objects with lighter colors. Someone wearing a white T-shirt in the summer will find that he is cooler than someone wearing a black or dark-colored shirt. This is true of all materials which have dark colors.

Plants deprived of light will lose their color and die. The shoots exposed to “limited/no” sunlight had a yellow/white color due to the fact that photosynthesis could not occur. The lack of sunlight stunted photosynthesis and therefore the sprouts were not able to produce the chlorophyll needed to create a green color.

The length of time a plant can survive without light can be between 4 to 20 day depending on the amount of light the plant is normally subjected to. Low light plants can go from 12 to 20 days, whereas light loving plants can merely last between 4 to 10 days before they die. Without light plants will die from chlorosis.

Answer: 1)Plants deprived of light will grow upward, stretching their stems more rapidly that usual, searching for light and plants that are denied sufficient light will eventually lose their color and die. The chlorophyll traps and packages the energy from the light of the sun in a process called photosynthesis.

Without the Sun’s warmth, Earth would quickly become a much colder place. Fortunately, Earth retains heat fairly well, so humans wouldn’t freeze instantly. Life would get much more difficult immediately, though. Without the Sun’s rays, all photosynthesis on Earth would stop.

Plants that are denied sufficient light will eventually lose their color and die. Plants deprived of light will grow upward, stretching their stems more rapidly that usual, searching for light. This process is known as etiolation and is a survival mechanism that maximizes the plant’s chances of getting to light.

Plants require sunlight to prepare food as they are autotrophic. So without sunlight, plants cannot prepare food and the plants will utimately die.

Light is required for chlorophyll production, and by the same token, lack of sufficient light results in the breakdown of chlorophyll. Chlorophyll, of course, is the green pigment in plants. These pigments are always present in the plant leaves; however, the green chlorophyll pigment masks their appearance.

If photosynthesis does not occur in plants then plants cannot synthesize the food. This causes the mbalanv=ce in the environment. The plants will not produce oxygen and then no animal life will be able to survive due to the absence of oxygen. We will not get oxygen, food, and life on this planet will be extinct.

Without a source of CO2, plants will die off, and without plant life the earth’s biological food chain would be terminally broken. The carbon found in biomass is taken out of the atmosphere through the process of photosynthesis which causes the plant grow.

Why Plants Need CO2 The reaction is powered by sunlight, and uses a combination of CO2 and water. Oxygen is the natural by-product. So, without carbon dioxide, a plant would basically starve even if you had a sunny spot, lots of water and even extra fertilizer.

Plants cannot live on CO2 alone; a complete plant metabolism depends on a number of elements. Plant growth has one limiting factor. In most of the world the limit is water. In mid-high latitudes it’s sunlight.

Most aquarium plants can survive without light for more than 5 to 7 days in a fully packed box container. However, some species of the plant are delicate, and they would require sunlight after few days. So they usually survive for approx 3 days.

2 to 3 days

Light Requirements for Aquatic Plants Aquatic plants do best under full spectrum light with a Kelvin rating or “color temperature” between 6,500K and 8,000K. Always choose a light source specifically designed for growing aquarium plants; those designed for houseplants do not have the correct Kelvin rating.

A plant can survive in the mail for 7 full days of shipping without any problems. Some plants can live up to 2 weeks. To ensure that your plant doesn’t dehydrate and begin to lose leaves, keep shipment below 7 days. If you have a plant needing less water or sunlight, you can extend past 7 days.

The Centers for Disease Control and Prevention tells us plants are not harmed by water treated with chlorine. Most of us have been watering our plants with chlorinated water for years and they survive.

Chlorinated water helps remove potentially harmful bacteria from municipal water sources, although large amounts of it can also throw water gardens out of balance. An excess of chlorine will kill off the algae, which may rob water lily roots of oxygen.

Swimming pool water contains chemicals, especially chlorine, that can harm your trees and landscape plants when water drains and floods the area. Too much chlorine can damage tree leaves and other delicate tissues. Too much chlorinated water all at once can even kill trees.

Mycorrhizae thrive if well-fed, and some growers use molasses-based concoctions to accomplish that. Chlorine and chloramine in public drinking water supplies will kill off a lot of them–probably something to consider before investing in expensive mycorrhizae inoculants.
