The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

Answer : </h3>
Enzymes are used catalists who speeds up the chemical reaction.
Therefore, correct option is :
B. Enzymes catalyze chemical reactions.
Answer:the fluffy white stuff is called the endosperm.
Explanation:
Monocots( also called monocotyledons) are plants that bears only one cotyledon, example includes corn, peas,beans and many among others. In the monocot seeds, they bear a carbohydrate components known as endosperm which feeds the new plant and it's found outside the seed coat.
The corn kernel is made up of four main parts which includes: endosperm, the pericarp, the germ, and the tip cap.
Endosperm is produced through the fusion of two sperm nuclei and an ovule inside a pollen grain. It's usually white or yellow in colour and is made up of carbohydrates.
Answer:
Enzymes are biological catalysts. Catalysts lower the activation energy for reactions. The lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy.
