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.


Germination of a starch seed?

When a starch seed germinates, enzymes break down the starch into glucose molecules. These glucose molecules are then used as energy sources by the growing seedling for various metabolic processes. Starch serves as a storage form of energy in seeds, and its conversion to glucose is essential for seedling growth and development during germination.


Where does a mielie store its starch?

A mielie stores its starch in the endosperm of the kernel, which is the main part of the seed where nutrients are stored for germination. Starch is a complex carbohydrate made up of sugar molecules that serves as a source of energy for the plant during germination and growth.


Which location of the bean seed contains the highest level of starch?

The cotyledons of the bean seed contain the highest level of starch. Starch serves as an energy reserve for the seedling during germination and early growth stages.


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.


Why do seeds need enzymes to convert starch for germination?

Seeds require enzymes to break down starch into simple sugars during germination because the plant embryo cannot use the larger starch molecules directly for energy. The enzymes help to convert starch into a form that the plant can easily use as a source of energy to support its initial growth until it can start photosynthesizing on its own.


What happen after you dropped iodine on cotyledons?

When iodine is dropped on cotyledons, it will turn blue or purple in the presence of starch. This color change indicates the presence of starch in the cotyledons. Starch is produced during photosynthesis by plants and stored in cotyledons as a source of energy for germination.


Is starch converted in seed metabolism?

Yes, in a process called "germination".


What will happen if your results indicate the presence of starch in the bean seed?

If your results indicate the presence of starch in the bean seed, it suggests that the seed has stored energy reserves, which are essential for germination and early growth. Starch serves as a vital carbohydrate source that the seed utilizes during the initial stages of development before it can photosynthesize. This finding can also indicate the seed's viability and overall health, as healthy seeds typically contain adequate starch reserves for successful germination.


What is epigeal and hypogeal germination?

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.

Starch


What is the function of endosperms of monocot?

The endosperm in monocots serves as a storage tissue for nutrients such as starch, proteins, and lipids, which are used by the developing embryo during seed germination. It provides essential nutrients for the growth and development of the embryo until it can establish its own photosynthetic capabilities.
