Answer:

guard cells
monocots: evenly distributed, dicots: more dense on lower leaf
Carbon dioxide

Explanation:

Stomata are pores in the leaf surface of plants. they regulate the exchange of moisture and gases in plants. They open at night for the exchange absorption of Carbon dioxide and expulsion of Oxygen, while closing at the middle of the day to prevent evaporation of moisture or water in transpiration. These pores are opened or closed depending on the state of the two surrounding guard cells.

The somata are found on both the upper and the lower leaf surface. in dicots, the stomata are noticeably denser on the lower leaf surface, while they are evenly distributed on both leaf surfaces on monocots.

Simora [160]

Most lipids are nonpolar. This property causes lipids to be water-insoluble in the bloodstream. Lipoproteins form water-soluble complexes for transport through the bloodstream by surrounding nonpolar lipids with polar phospholipids and proteins .

A central hydrophobic core of non-polar lipids, predominantly cholesterol esters and triglycerides, makes up the complex particles known as lipoproteins. Since lipids like cholesterol and triglycerides are not soluble in water, they must be carried in the bloodstream along with proteins called lipoproteins.

These lipoproteins are essential for the small intestine to absorb and transport dietary lipids, for lipids to travel from the liver to peripheral tissues, and for lipids to travel from peripheral tissues to the liver and intestine.
