Answer 1

Answer:

a) When guard cells take up these solutes, the water potential inside the cells decreases, causing osmotic water flow into the guard cells. This leads to a turgor pressure increase causing swelling of the guard cells and the stomatal pores open.

b) In all autotrophic eukaryotes, photosynthesis takes place inside an organelle called a chloroplast. In plants, chloroplast-containing cells exist in the mesophyll

c) Nitrogen is a major essential element for all organisms, and a constituent of proteins, nucleic acids and other indispensable organic compounds.

d) Only when nitrogen is converted from dinitrogen gas into ammonia (NH3) does it become available to primary producers, such as plants. In addition to N2 and NH3, nitrogen exists in many different forms, including both inorganic (e.g., ammonia, nitrate) and organic (e.g., amino and nucleic acids) forms
