Answer:
Ferns do not have true leaves as many plants do, but structures called fronds. These fronds are split down into leaflets called pinnae. These fronds are green and the fern gets its food via photosynthesis. Ferns reproduce by spores in an alternating generations.
Explanation:
i studied ferns for years
The chemical reactions in the cell would not happen as fast and would require more energy to catalyze the reaction between the two reactants.
Mark brainliest if I helped you
Chemistry/ Example: Take breathing for example, when you breath you breath out carbon dioxide. The CO2 can't just leave like that and only 10% binds to hemoglobin. The rest turns into carbonic acid in your blood and its plasma. However, the acid is unstable, so it turns into bicarbonate and a dissociated proton (H). You have carbonic anhydrase that converts the two so you can breath out CO2; the carbonic acid separates into H2O and CO2. This process would take a LONG time without the enzyme-- CO2 build up, even minimal amounts it lethal.
I think its A but I'm not sure.
