This zone is called as the zone of aeration. It is present between the earth's surface and the water table, and its main constituents are the soil and rocks. The pores which are present in this zone are partly filled with water, and may mix up with air, causing aeration.
Light energy is absorbed by a chlorophyll molecule and the photon is passed along a pathway to other chlorophyll molecules. The energy culminates in a molecule of chlorophyll found in the reaction center.
Cohesion. Cohesion is the property of water that attracts other water molecules so they can stick together. Water is sticky because it has positive and negative charge in the oxygen and hydrogen ends that attracts one water molecule to another. Adhesion is also a property of water that attracts it from other substances, making it easy for water to travel upwards through transpiration.
The cytoplasmic streaming can be defined as the movement of the cytoplasm inside the cell. This movement of the cytoplasm helps in the delivery of the metabolites, organelles, and nutrients to all the parts of a cell. The cytoplasmic streaming, which is also known as cyclosis, occurs at the same rate throughout the cell and moves in the direction of the light.
Hence, the answer is 'moves at same rate and towards light'.
