Leaves are adapted to perform their function. They have a large surface area to absorb sunlight .Plants have different types of 'transport' tissue, xylem and phloem, that move substances in and around the plant. Water evaporates from the leaves, resulting in more water being drawn up from the roots (Bolhar et al ,1993). A leaf is made of many layers that are sandwiched between two layers of tough skin cells. The epidermis secretes a waxy substance. These layers protect the leaf from insects, bacteria, and other pests. Among the epidermal cells are pairs of sausage-shaped guard cells. Each pair of guard cells forms a pore. Gases enter and exit the leaf through the stomata. Cross section of a leaf is shown in Figure 1.1(i) Most food production takes place in palisade mesophyll. Gas exchange occurs in the air spaces between the oddly-shaped…show more content…
It results in the formation of the seedling. It is also the process of reactivation of metabolic machinery of the seed resulting into the emergence of radicle and plumule. Seed germination depends on both internal and external conditions. The most important external factors include right temperature, water, oxygen or air and sometimes light or darkness. Environmental conditions must trigger the seed to grow. Usually, this is determined by how deep the seed is planted, water availability, and temperature. The water activates enzymes that begin the process of seed growth. Initially the seed grows a root to access water underground. Then the seed sends a shoot towards the surface, where it will grow leaves to harvest energy from the sun. Soak the seeds in water 24 hours before sowing. Two or three bitter gourd seeds can be sown together in a pit 2cms deep. Usually the seeds will germinate in 3-7 days. The germinated seeds can be replanted 45 cm to 50 cm apart on raised beds. In germination stage there are leaves with lobes and without

    EFFECT OF TEMPERATURE ON GERMINATION LAB REPORT By : Ayşe Sağlam 10-A 07. December. 2015   Introduction: Germination is the process of the plant developing from the seed. There are several factors, which affect the germination rate and speed. These factors include light, temperature, oxygen and water. If the condition the seed is in is not suitable for germination, (such as lack of water or very low or high temperatures) the seed will remain inactive. If the conditions
