A seed contains an embryo plant. it also contain a food store on which the embryo will rely while it is germinating, until it has grown leafs and can start to photosynthesise. For example bean seeds contains a lot of starch. Starch is insoluble. When the seeds begins to germinate, the enzymes amylase is secreted. This breaks the starch into maltose, which is soluble. The maltose can then be absorbed by the growing embryo, which can break it down to glucose. The seedling can then use it to supply energy for growth, and also to build up cellulose to make up cells walls for the new cells that are made as the seeding grows
During germination, the testa, or seed coat, often remains intact for a period of time but may eventually split or break apart as the seedling emerges. The primary function of the testa is to protect the seed during dormancy, and it can sometimes hinder the germination process if it is too tough. However, in some seeds, the testa may soften or be breached by the growing embryo, allowing the seed to sprout. Overall, the fate of the testa during germination varies depending on the species of plant.
Absorbing water softens the seed coat, triggering biochemical changes that activate enzymes responsible for germination. This process allows the seed to break dormancy and initiate growth by providing necessary moisture for metabolic processes.
Germination is the process by which a seed sprouts and begins to grow into a plant. It involves the absorption of water, activation of enzymes, and initiation of cell growth. Germination is essential for plants to establish and grow into mature individuals.
The cotyledon is broken down by enzymes within the seed during germination. These enzymes help to digest stored nutrients within the cotyledon, providing essential energy and building blocks for the developing seedling.
Water is the most important liquid needed for germination. It helps to soften the seed coat, activate enzymes, and provide the necessary moisture for the seed to begin the process of sprouting and growing.
Enzymes play a large role in seed germination. The enzymes break down the materials that are stored in the seed.
Oxygen is the primary gas needed for germination. It is required to activate enzymes that control the metabolic processes within the seed during germination.

Oxygen gas is needed by the seed during germination. Aerobic respiration takes place during seed germination to release lots of energy required for this process.
Epigeal germination is when the cotyledons emerge above the soil surface during seed germination. Hypogeal germination is when the cotyledons remain below the soil surface during seed germination.
Seed germination requires water, proper temperature, oxygen, and sometimes light. Water helps soften the seed coat and activates enzymes needed for growth. The right temperature is crucial for metabolic processes to occur, while oxygen is essential for cellular respiration. Light can also be a trigger for germination in some plant species.
during germination
The embryo in a seed gets its food from the endosperm or cotyledons within the seed. During germination, enzymes break down the stored food reserves in the seed to provide energy for the embryo to grow and develop into a seedling.
The enzymes in the dry seeds get activated after absorbing water and it unlocks several chemical reaction leading to the germination of seed.
Epigeal germination is the process in which the seed leaves or the cotyledons are brought on to the surface along with the shoot during germination. Hypogeal germination is the process in which the seed leaves or the cotyledons remain below the soil surface during germination.
