a. Sugar cane, corn, carbgrass which are identified as C4 Plants allow fixation of carbon dioxide into four carbon compounds. This happens during the hottest time of the day - their so-called stomata gets partially closed. C4 plants have been identified to lose only half of the water that C3 plants lose when they produce the similar amount of carbs.

b.CAM PATHWAY - Plants such as pineapples and cactus have different approach to adapting heat. Carbon is fixed through a cam pathway. They use it to open their stomata at night and close it in the morning.

Answer:

- Eukaryotes are organisms that contain more than one cell with membrane-bound organelles and a nucleus.

- Organisms that contain only one cell and do not contain a nucleus or membrane-bound organelles are known as prokaryotes.

Explanation:

According to their structural and functional complexity, organisms can be classified into eukaryotes and prokaryotes.

Eukaryotic organisms are formed by cells that have a true nucleus -where DNA is located- and specialized structures called organelles, with a system of endomembranes that compartmentalize the intracellular space. These organisms are usually pluricellular, given the ability of eukaryotic cells to group together to form tissues.
Prokaryotic organisms are single cells, lacking a nucleus - genetic material is scattered in the cytoplasm - and do not possess organelles. The prokaryotic cells that form these organisms are incapable of binding together, so they do not form tissues.

Some unicellular organisms are prokaryotic cells, like some parasitic microorganisms, such as amoebas.
