What are some of the functions of photosystem i and photosystem ii in plants?
Sidana [21]

Answer:

Photosystem I (PS-I )and photosystem II (PS-II ) are two multi-protein complexes. These complexes contain the pigments used to absorb, harvest and catalyze the photons and light energy in the photosynthetic reactions. The main purpose of photosynthesis reactions to produce high chemical energy compounds.

Photosystem I and II are different from each other because of their absorbing wavelength of light. PS-I absorbs the longer wavelength of light than PS-II.

PS-I plays the major role in the production of high energy carriers ATP and NADPH using light energy (700 nm).

PS-II plays its function in the hydrolysis of water and ATP synthesis using light energy (680 nm).

erica [24]

Answer:

Eukaryotic and Prokaryotic cells are fundamentally different.

Explanation:

A prokaryotic cell is basically an entire organism that works within a single cell. Its genetic material is not in a nucleus.

A eukaryotic cell is part of an organism. This cell has its genetic material in the nucleus. In addition, it possesses organelles.

All cells are not the same because some, like the prokaryotic ones, make up an entire living organism. Others, like the eukaryotic cells, are part of much more complex living forms. Furthermore, each cell type within each category has unique functions.

An efficiency apartment can be compared to a prokariote. Prokariotes have everything they need in one cell. A mansion is more similar to a eukaryote. Every room of the mansion is important for the fully equipped mansion.
