Rzqust [24]

Answer:

a monocot

Explanation:

Monocotiledoneas are plants that develop from a seedling with a single cotyledon. That is why we can say that maize is a monocotyledon.

Monocotyledons and dicotyledons are two classes of vegetables that belong to the angiosperm plants (plants with seeds contained within the fruits) and also phanerogams (flowering plants), currently classified as magnoliophytes, gathering approximately 230 thousand species. Monocotyledons are plants that have only one cotyledon in the seed. Cotyledons are the initial leaves of plant embryos.

Zielflug [23.3K]

Enzymes are classified and named according to the<u> types of reactions they catalyze.</u>

Explanation:

According to the International Union of Biochemistry and Molecular Biology nomenclature of enzyme classification, enzymes are classified depending upon the reactions they catalyze and how the reaction transforms the substrate and forms new products.

Based on the reactions:

Addition reaction (removal of a water molecule): hydrases or hydrolases like esterases, nucleases etc

Electron transfer reaction: Oxidases and dehydrogenases

Radical transfer reaction: Transglycosidases, transaminases, etc

Splitting or C-C bond formation: Desmolases

Structural or geometrical change: Isomerases

Hydrolysis of phosphate bonds to join molecules: Ligases

Based on the general principle of recommendations, enzymes are suffixed with –ase  depending upon the catalytic reaction and substrate.

DedPeter [7]

The stomata of plants will close during hot and dry day. This cause a decrease in concentration of carbon dioxide and increase in oxygen concentration in the plant. Photorespiration occur.

As carbon dioxide in photosynthesis is used to produce glucose molecules, the production of glucose molecule will decrease.
