Most leaves are green because they contain the pigment chlorophyll.
Chlorophyll, a chemical which gives leaves its vivid green color, makes all of this happen. When the trees notice the days becoming shorter and the nights getting longer, their ability to synthesize chlorophyll reduces. Thus the green disappears and yellow and orange carotinoids and xanthophylls, which were always present, but hidden within the leaf, shine forth their colors. Other chemicals are produced that make the leaves appear red and purple. Any water and nutrients that were in the leaves go down to the stems as the tree prepares for the winter. When no food is left in the leaf, it falls, leaving behind a scar and a bud for the next year's growth.

What is the effect of light on the growth of plants?
The effects of light on plants are divided up into four main categories. Photosynthesis is the process where plants convert light energy into chemical energy. Photoperiodism is the relative effect of the length of daylight to the flowering of plants. For example, "long day" plants flower when daylight is longer than a certain length of time, and "short day" plants flower when daylight is shorter than a certain length of time. Phototropism causes plants to grow according to the direction of the light source. Some may bend on an angle and grow that way toward light. Photomorphogenesis is the effect caused by the quality and intensity of light. Some seeds need light to germinate, etc.
Photosynthiesis effect on the growth of plants in light or dark?
Photosynthesis occurs in the presence of light as plants use light energy to convert carbon dioxide and water into glucose and oxygen. In the absence of light, such as in darkness, plants rely on stored energy reserves for growth and metabolism. Light is essential for photosynthesis to occur and support plant growth, so plants will not grow in total darkness.
How is light a limiting factor?
Light can be a limiting factor for photosynthesis in plants as it is necessary for the process to occur. Insufficient light can reduce the rate of photosynthesis, affecting plant growth and development. Different plants have different light requirements, so the availability and intensity of light can determine their ability to thrive in a particular environment.
Does light effect the direction of growth of a plant?
Plants need light and they will grow towards where they receive an optimal amount; plants will face where the light is. You can experiment on your own by growing your own plant and using a desk lamp as the light source. As the plant grows, it will lean towards and face the light source directly.
Phenomenon observed when beam of light passes through a colloid?
The Tyndall effect is observed when a beam of light passes through a colloid, causing the light to scatter and become visible. This phenomenon occurs due to the particles in the colloid being large enough to scatter light, unlike in a true solution where particles are too small to scatter light. The Tyndall effect is commonly used to determine if a mixture is a true solution or a colloid.
What is the independent variable in an investigtion to find how light effects the growth of plants?
The independent variable in this investigation would be the amount of light received by the plants. This variable is controlled and manipulated by the researcher to determine its effect on plant growth.
How does light waves effect plants?
It effects other plants because plants need the proper light and plants can move a little bit to see the light.

Do light colors effect plants growthIn what way?

How does light effects plants?
How does light effect plants is a broad topic for one most plants like sunlight (light). For plants that require light it is very important for them to produce photosynthesis the prosses of turning light into energy. Although the color of light can also effect a plant for example blue light = growth, Blue & Red light = Flowering and green light = nothing.
How does light effect plant growth?
Light effect plant in 3 ways , 1: blue and red light effect photosynthesis , Photo peroid effects flowering in plants , . Light of different color effect cell division and enlargement .
Does sun light effect a plants growth?
There are citaian essesntial of a plant one of them is sun light
How tyndall effect can help you determine if a mixture is a colloid or not?
The Tyndall Effect can help determine if a mixture is a colloid by observing if the mixture scatters light. Colloids will scatter light, causing the light beam to become visible when passing through the mixture. If the mixture does not scatter light, it is likely not a colloid.
Does clear light effect plants?
yes because it gives the plant more light than if it were clouded.
What is the control variable in the experiment does adding fertilizer to plants allow them to grow faster?
The control variable in this experiment would be the plants that do not receive any fertilizer. By comparing the growth of plants with fertilizer to those without, researchers can determine the effect of adding fertilizer on plant growth.
What is the relationship between the intensity of light and its effect on plant growth?
The relationship between the intensity of light and its effect on plant growth is that higher light intensity generally leads to increased photosynthesis and growth in plants. Light provides the energy needed for photosynthesis, the process by which plants make their own food. Therefore, plants exposed to higher light intensity are able to produce more food and grow more quickly. However, too much light can also be harmful to plants, causing damage to their cells and reducing growth. It is important for plants to receive the right balance of light intensity for optimal growth.
Does the color of light used on plants effect how well they grow?
Yes, different colors of light can have varying effects on plant growth. For example, red and blue light are most important for photosynthesis, while green light is less effective. Plants can also respond to different light colors by changing their growth patterns and flowering abilities.
