marco and natalia, two curious students, are interested in what happens in a plant seed very early in germination - before anything turns green. they put seeds dehydrated in a dark sealed container and measure (a) the amount of lipids and carbohydrates in the seed and (b) the amount of oxygen and co2 in the headspace (see the experimental setup below). they add water to initiate germination. very early after adding water they remeasure (a) and (b) from above. their data is displayed in the charts below.

Respuesta :

In plant seed early in germination - before anything turns green. they  put seeds dehydrated in dark sealed container & measure, (a) number of Lipids: 0.4% & Carbohydrates: 0.8% in the seed.  (b) The amount of Oxygen: 0.5% and CO2: 0.2% in headspace.

Marco and Natalia's experiment shows that adding water to a plant seed initiates metabolism that use the stored lipids and carbohydrates for energy. The increase in oxygen and CO2 indicates that the metabolic processes are producing these gases as byproducts. This suggests that the seed is beginning to respire and grow  metabolism Convert food into energy. Metabolism is process by which body converts food & drink into energy. During this process, calories from food and drink mix with oxygen to create the energy your body needs. Even at rest, your body needs energy to do anything.
