Seeds can often last for several years, often in very tiny forms. Despite how small seeds can be, they are very good at growing with a minimal amount of energy until they spring from the earth and begin photosynthesis. The plant is able to grow into something as large as a sequoia because of how efficiently it can establish a root system and locate sunlight.
Plants sprout from seeds. Water weakens the seed wall, making it easier for the plant to push out of the seed, according to I Love India. Endosperm is the food that fuels the plant embryo’s growth, allowing it to break free of the seed and grow roots to find water and nutrients, according to Washington State University.
Cotyledons form on plants. These cotyledons are the beginnings of leaves, according to I Love India. The cotyledons eventually become thinner and broader to cover more area and absorb more sunlight with the minimal expenditure of energy. These leaves also develop veins to allow more water, nutrients and adenosine triphosphate to travel to and from the leaves.
A taproot travels into the ground in search of water. When the tap root finds water, root hairs grow outward and try to absorb as much water and nutrients as possible, according to I Love India. Many roots will continue to expand when water and nutrients are not sufficient. Many plants share root systems, according to the University of Illinois. Water and nutrients fuel the multiplication of plant cells, which causes the plant to grow.
The top of the plant grows towards sunlight so that photosynthesis can occur, according to I Love India. The stem of the plant emerges from the soil. The stem and leaves gradually emerge from the ground. The stem is crucial because it not only gets the leaves closer to the sun but also acts as the pipes for bringing water and nutrients to the leaves, which allows them to grow. The stem also brings sugar back down to the roots, according to the University of Illinois. The stem and leaves try to grow towards the sunlight over time so that they can absorb more sunlight for the process of photosynthesis.
Photosynthesis allows the plant to generate much more energy than it can get from the nutrients in the soil. Sunlight lands on the leaves of the plant and is absorbed into the chlorophyll, according to Estrella Community College. Through respiration, which involves the absorption of carbon dioxide, the sunlight breaks down the carbon dioxide, unleashing a multiple-step chain reaction, creates adenosine triphosphate, which is the basic fuel source of all living things, and releases oxygen, which is an important element for the absorption of nutrients in the soil.
