Write the Factors Affecting Plant Growth

Explanation:

Factors Affecting Plant Growth

There are four major factors that affect the growth of the plants. They are:

Light

Plants are autotrophs. They require light for manufacturing their food. Limited light or the absence of it greatly affects the growth of the plant. The intensity of light, quality of light, and light duration influence the movement of stomata, chlorophyll synthesis, photosynthesis, and various other physiological factors. Light also encourages flowering and fruiting. During winters when the days are short, the growth of the plants is retarded.

Water

Plants cannot survive without water. Around 90% of the plant body comprises water. Plants become stressed in the absence of water and die. Water present in the soil is absorbed by the plant, which absorbs and transports the nutrients along with it. Water keeps the plant hydrated.

Temperature

Plant growth is greatly influenced by temperature. High temperatures speed up transpiration, photosynthesis, and germination processes. Low temperatures, however, slow down the growth of the plants.

Nutrients

Just like human beings, plants require proper nourishment for their growth and development. Soil nutrients are divided into macronutrients and micronutrients. Nitrogen, potassium, calcium, magnesium, sulfur, and phosphorus are the macronutrients required by the plants. The micronutrients include iron, copper, etc. Deficiency of these nutrients in plants makes them prone to several diseases. Even if a single nutrient is lacking, it results in stunted growth of the plant.
