Class 5 Science Seed Germination Youtube Foliage leaves are not useful to the baby plant and fall off soon. 2. the cotyledon photosynthesise to give energy to the baby plant, until the baby plant gets its own leaves to photosynthesise. 3. the cotyledon later become the first leaves of the seedling when the seed germinates. 4. The first step of seed germination is called imbibition. step 2. the seed coat splits. step 3. a first root grows (called “the radicle”) downward and begins to absorb water and minerals from the soil through the tiny root hairs. additionally, the roots support the plant and prevent wind or animals from completely tearing it apart.
Seed Germination Definition Steps Factors Affecting Them First, let’s learn a bit more about germination. seeds grow into a new plant through a process called germination. germination is the sprouting of the seed or the very beginning of plant growth. availability of water, cold temperatures or warm temperatures, oxygen, and light exposure may all be a factor in starting germination or keeping the. External factors. water: the poor or additional supply of water affects seed germination. temperature: this affects the growth rate as well as the metabolism of the seed. oxygen: germinating seeds respire vigorously and release the energy required for their growth. therefore, deficiency of oxygen affects seed germination. Materials. for your seed germination experiment, you will need: a glass jar. paper towels. water. and seeds! instructions. first, we pushed sheets of paper towels, one at a time, into the glass jar. once it was full, we added some water to wet it (dumping out any excess). Steps of germination. when conditions are right the seed starts to take in water. as water is taken in, the seed swells bigger and bigger until the coat splits apart. air can then get to the seed. so, the oxygen in the air helps the baby plant burn the food packed inside the seed. burning the food produces energy.

The process by which a seed grows into a young plant, or seedling, is called germination. a seed germinates only when it gets enough light, air, water, and warmth. during the early stages of germination, the seedling uses the food stored inside the seeds for its growth. when the seed receives adequate light, water, air, and warmth, it becomes.
