At least 7hrs and warm too.
Transpiration is controlled by stomata.
Generally, the more light, the more plant growth. Color is more related to the type and amount of nutriments or fertilizer in the soil. ....More Info Amount of sunlight does affect growth and LEAF colour of plants. Sometimes flower colour is affected as well. Certain plants do better in shady, low-light locations than in full sun locations. Shade loving plants planted in hot sunny locations often have pale, semi-transparent leaves sometimes with brown dry edges (water is evaporating too fast from the plant and too intense sunlight is 'bleaching' colour, basically dehydration and sunburn is occurring.), and may grow thin and weak. Sun loving plants planted in shady low-light locations often have darker or lighter coloured leaves, fewer & smaller flowers and can look weak and thin. Greatly reduced sunlight for sun-loving plants can also stunt growth.Flower colour is determined by plant genetics. Inappropriate sunlight may slightly alter flower colour to a paler or deeper shade of the same colour and NOT change from red to white. Example: "Nellie Moser", a Clematis, grows well in both sunny and shady locations. Flower is a much deeper shade of pink when grown in the shade.
too much heat, it gets cooked
The root system and the central vacuole.
All fruits have pigments. The pigments are what give the fruit/plant colour. Eg: the colour of a leaf if green.. this means that the leaf will absorb every colour BUT green, green is reflected. This can apply to fruits too.
Such plants tend to store water in swollen leaf cells, and are generally classed as succulents. The waxy leaf surface is to prevent too much evaporation of water due to the heat.
What should be the effect of too much sunlight to growth by plants?the plant might dry up
Smoking, too much alcohol, too much (direct) sunlight, too much exercise, too much fatty food, too many carbohydrates.
Too much sunlight on the tank!!
Too much sunlight dries up the soil... Ferns require moisture in order for fertilization to occur.
Some of the sunlight exists as ultraviolet light. Too much exposure to this can cause skin cancer.
Well think about it! Plants need sunlight to produce energy for themselves and grow. The leaves absorb the sunlight,thus, other leaves don't shade other leaves, cause all the leaves need sunlight. P.S. I'm not too sure if all plants arrange their leaves that way, you may want to check your sources.
Well one risk is that too much sunlight could give us Skin Cancer.
Plants need sunlight and water to grow. It will die without water, and it will die without sunlight, it is just a matter of time. Different plants need different amounts of water and sunlight. What is not enough water for a rose may be too much water for a cactus. Likewise, what is not enough sunlight for a rose, may be too much sunlight for a rhododendrum. A plant with too little sunlight will not grow to it´s full height, and a plant with too little water will not grow to it´s full height either.
yes, it is a water proof layer that stops the leaf loosing too much water.
Yes, all plants need sunlight in order to survive. Just be careful not to give them too much direct sunlight or they will dry up from too much heat. Cacti are probably the longest-lasting plants in direct sunlight because they are desert plants and are made to survive extreme heat.
