What is the function of some enzymes is a seed during germination?

Answer 1

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

Answer 2

A seed contain a store of food which will sustain it until it is able to produce it's own food by photosynthesis. However, the food in the seeds is complex, insoluble molecules which need to be converted to useful substances. Enzymes help to convert them. This process of convertion is called mobilisation.

Answer 3

Until a plant can make its own food by the chemical process of photosynthesis, seeds have to support the plant and provide everything it needs. However, the food inside the seed is not in the form of simple sugars (which is what the cells of the plant need), but instead in the form of complex, insoluble molecules such a protein and starch. Because of this, mobilisation takes place to convert the molecules into something useful to the plant. Mobilisation happens because of enzymes which digest the large molecules.

Answer 4

seeds contain a store of food that supports the plant until it can make its own food by photosynthesis. the food store does not exist as the simple sugars need by the cells it contains insoluble molecules like starch and proteins. ( these store foods in the fruits and seeds make them useful for us humans)

so lets say for example bean seeds contain a lot of starch and starch is insoluble so when the seeds begin to germinate the enzyme amylase is secreted. this breaks the starch into maltose which is soluble. the maltose is then broken down int glucose.

hope this helped :)

Answer 7

The significance of production of enzymes in the germination of seeds is tat it means that germination has began. The activation of enzymes, plant cells duplicating and an increase in respiration are the first signs of germination of a plant.

Answer 8

Germinating seeds use enzymes to speed up the rate of photosynthesis.
