Description

Termini 1 Isabella Termini Biology Lab My Daniels-Abdulahad 19 November 2019 Growing Pea Plant Assignment Journal A cup was filled with soil and a germinated pea was placed a little under the surface of the soil. The pea plant was placed on the windowsill and watered with tap water twice a day. Temperature conditions were under room temperature because the windowsill is directly above the air-conditioning. In the morning, the pea plant was saturated with water and was still damp by the afternoon, but a little more water was added each afternoon. This caused the pea plant to become water-logged. The plant drowned by the third day and died. It also didn’t not receive enough sunlight because the curtains blocked about 2 hours of needed sunlight each day. They were not opened all day, so direct sunlight was not reaching the pea. Therefore, the pea plant died, and mold began forming around the germinated peas. Now, there is a layer of mold on top of the soil. In ideal cases, the plant would have grown to 7 meters. Pea plants grow best without fertilizer in neutral soil with a pH of 6 to 6.5. During the first stage of growth, no light is needed for the pea plant to start growing because roots begin sprouting under the soil. After the first stage of growth, at least 6 hours of direct sunlight is needed daily for the pea plant to undergo photosynthesis and grow. Watering the pea plant is also an important factor for growth. The surrounding soil should’ve been damp and not saturated for the peas to germinate. Too much water causes the plant to decay and too little water causes the plant to shrivel and dry out.

Termini 2 Temperature should have been between the range of 45 to 65 degrees Fahrenheit because colder temperatures delay germination. Photos
