water‚ exposure to sunlight‚ and conditions of surroundings. Due to certain stimuli in the surroundings plant “hormones” cause plants to behave in ways that ensure the most efficient use of resources while preserving the most energy. One stimulus to consider‚ is the exposure of plants to sunlight; when plants are just sprouting and are underground‚ the stimulus of not having any sunlight prevents the plants from growing chlorophyll and thus from growing leaves. SInce no sunlight is present underground

Axis Tilt The Earth is tilted on it’s axis at about a 23.45 degree angle perpendicular to the Plane of the Eclipt. Because of Earth’s tilt‚ different regions of earth receive different amounts of direct and indirect sunlight. We call these various periods of time the seasons. When the Northern Hemisphere is tilted towards the sun it is experiencing summer‚ simultaneously‚ the Southern Hemisphere is experiencing winter‚ because it is tilted away from the Sun. During the Winter‚ the days are shorter

What causes the seasons? Earth’s seasons are created by the direct and indirect sunlight that locations on Earth receive during the year‚ which is caused by the Earth’s constant 23.5˚ tilt toward the north star‚ making the direct sunlight locations get differ throughout the year. The Angle of Sunlight Lab‚ measured the temperature of the Northern and Southern Hemisphere while a light source was directed at it for 8 minutes. The position of the Earth simulated what December looks like for Earth

Light is the main source of plants for food production‚ and also for the growth of a plant. It is needed by a plant in order to survive. Natural light is the best light needed by plants‚

energy from lights. Chlorophyll is present in specialised cells within plants and many algae‚ when sunlight is present‚ chlorophyll combines it with water and carbon dioxide and creates energy through photosynthesis‚ a bi-product of which is oxygen. Organism that can photosynthesise are called autotrophs or “self-feeders”. Chlorophyll in leaves enables plants to trap light energy; it traps sunlight energy for the plants and begins the process of photosynthesis. It gives plants the greenish colour
