In the endosperm of a seed, there is a storage of starch which provides energy, required during germination. To tap into this energy and make it available to the embryo of the seed, the starch is first hydrolysed by an enzyme (alpha amylase) and converted into maltose (a disaccharide), then in turn, maltose is hydrolysed by the enzyme maltase to form glucose (a monosaccharide). The resulting glucose can then provide energy in the form of ATP and be used for growth by the embryo of the seed. Hope this helps.

What happens to starch before it is used for germination?
It has to be turned into a sugar, such as sucrose.
This developing plant uses starch stored in the seed as a source of energy during germination This stored starch is a by-product of?
The stored starch is a by-product of photosynthesis. Photosynthesis produces glucose; plants can convert and store excess glucose as starch. Both sugar and starch are types of carbohydrates.
Is starch converted in seed metabolism?
Yes, in a process called "germination".
Why do seeds need enzymes to convert starch for germination?
digestive track
What gas is needed by 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.
How does the embryo get food for germination?
The seed embryo is nourished by stored starch in the plant.
State the difference in how seeds react for both types of germination?
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.
Indicator used during the standardization of sodium thiosulphate?
Starch
Effects of overcrowding during seed germination?
sometimes it encourages germination and sometimes it inhibits it. its hard to tell when.
When does the seed turn green?
during germination
What does plants need to make starch?
light is required by the plants to activate their chlorophyll smallest unit of light energy is a photon which also dissociates water molecules in a plant .this process is called photolysis which is used in production of starch
What is liquid starch?
Liquid starch is a liquid made with cornstarch and water and used on fabrics during ironing for a very stiff result.
