The correct answer is taxonomy,
Taxonomy is a branch of biology that aims to to sort living thing into categories. In its early years, taxonomy was solely based on structural comparisons, mostly the anatomical similarities and differences between the organisms. However, with the discovery of the physiological processes and the genetic structures of organisms, the previous taxonomic knowledge was revised and changed in the light of the new scientific finds. Nowadays, taxonomy is primarily based on genetic similarities between the organisms.
Answer:
Cells are small because they need to keep a surface area to volume ratio that allows for adequate intake of nutrients while being able to excrete the cells waste. That is why the cell needs to be small. The smaller it is, the larger the surface area to volume ratio is. ... This is why cells are so small.
explicación:
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. ... That is why cells are so small.
Cells are small to have a high surface-to-volume ratio and efficient exchange of materials with their environment.
All cells are very small because they need to have a high surface-to-volume ratio. The surface area of a cell determines the amount of substances that can enter or leave the cell, while the volume of the cell determines the amount of metabolic activity that can occur. By being small, cells can efficiently exchange materials with their environment and carry out essential functions.
For example, red blood cells are small to pass through the narrowest capillaries and transport oxygen to different parts of the body. Bacteria are also small to facilitate their nutrientuptake and waste removal.
Furthermore, the small size of cells allows them to have a faster rate of diffusion, which is important for the exchange of gases, nutrients, and waste products across the cell membrane.
