Answer:

Plant species have had to adapt to freezing and the presence of ice in many climatic zones.

Explanation:

Cold environments are an important ecosystem with distinct characteristics and adaptations. They provide opportunities for development, but are put at risk by the exploitation of resources. In order for plants to survive in cold environments they have had to adapt to the extreme conditions found there. These plants  produce storage organs below ground, to survive in the cold climate.

Answer:

The correct answer is D) photolysis

Explanation:

Photolysis is a process in which light energy is used by photosystem II to split water which generates oxygen, H⁺ions end electrons. oxygen is released in the atmosphere and inhaled by animals and electrons are used to generate energy.

The electron released by the splitting of water is transferred to the first electron acceptor called pheophytin. This electron is passed through a series of complex and produce energy in the form of ATP and NADPH.

The process of photolysis does not occur in photosystem I because lysis of water takes place and electron is passed from photosystem II to photosystem I.
