factors affecting photosynthesis internal factors

Anatomy which favours the amount of CO 2 diffusion into collenchyma cells the intensity dilution of light and the rate of photosynthesis. Thickness of epidermis, size structure, position and frequency of stomata, distribution of vascular tissue and intercellular spaces, position an..

Factors Affecting Photosynthesis - External Factors - Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors..

Photosynthesis is influenced by two categories of factors - external or environmental and internal or plant factors. According to the law of limiting factors, put forward by F.F.Blackman in 1905, photosynthesis is limited by the most..

The concentration of chlorophyll affects the rate of reaction as they absorb the light energy without which the reactions cannot proceed. Lack of chlorophyll or deficiency of chlorophyll results in chlorosis or yellowing of leaves. It can occur due to disease, mineral deficiency or ..

Light Intensity - Low light intensity lowers the rate of photosynthesis. As the intensity is increased the rate also increases. However, after reaching an intensity of 10,000 lux (lux is the unit for measuring light intensity) there is no effect on the rate. Very high intensity may, in fa..

Growth regulators - There are several known growth regulators. Some of them like auxins, cytokinins are growth promoting while others like abscissic acid, ethylene are growth inhibitors. Most of the growth regulators are synthesized by plants while a few are synthetic in natur..

Factors affecting Plant Growth - Plant growth is influenced by a number of external and internal factors. The external factors affecting plant growth are: i) light ii) temperature iii) oxygen iv) carbon dioxide v) soil water vi) soil nutri..

Light - The effect of light on growth can be studied under 3 headings light intensity, light quality and duration of light. Growth is generally favoured by darkness, but light is indispensable because of its role in the manufacture of food. Young plants growing in the absence of light develop elong..

Structure of the Leaf - Variations in leaf structure to reduce transpiration: Xerophytic plants have small leaves thick cuticle sunken stomata covering of epidermal hairs well developed palisade parenchyma to reduce transpiration increased wax deposits on leaves conifers like pines have leaves redu..

Factors Affecting Resistance - The resistance of a conductor is affected by the following factors..
