How are the electrons freed to go through the electron transport chain in photosynthesis? a. Sunlight is absorbed by chlorophyll, chlorophyll uses the energy to release electrons into the Thylakoid membrane
b. Sunlight is absorbed by chlorophyll, chlorophyll uses the energy to produce a photon that can split water, water releases the electrons
c. Sunlight is absorbed by chlorophyll, chlorophyll becomes excited and the increased energy causes an electron to become loose, NADP+ is able to attract the electron to start the chain
d. I guess I should study for the final.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
