The correct option is this: BOTH MOVE MATERIALS DOWN A CONCENTRATION GRADIENT.
Active transport is a type of transport in the living cells in which energy is needed to move materials across a semi permeable membrane against a concentration gradient. Passive transport on the other hand is a type of transportation in cells, in which energy is not needed to move the materials across a biological membrane but the movement of the materials is against a concentration gradient.
Both elements are coinage metals and they are godd conductor of electricity and heat.
Hope I helped !
Answer:
The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP. The third phosphate chemical bond contains the new chemical energy.

Answer:
The correct statement is
Option D. Plants use light energy to produce food molecules during photosynthesis and obtain cellular energy from the bonds of these food molecules during cellular respiration.
Explanation:
Photosynthesis is food producing process in which food is produced by plants in the presence of sunlight while respiration is energy releasing process in which energy is released due to the breakdown of glucose molecules.
