Observation of Diffusion Rate in Relation to Cell Size

Biology
1 answer:
vesna_86 [32]3 years ago
4 0

Explanation:

new cells rather than growing bigger. Why is this ?

There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.

Why aren't you made of a few dozen, or a

few hundred cells, instead of trillions?

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. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.

Why don't single-celled organisms like amoebas and paramecia grow

as big as a human?     again 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.

the molecules shown in this image are able to cross membrane through facilitated diffusion. how will they be transported?
Ira Lisetskai [31]

Answer:, facilitated diffusion differs from passive diffusion in that the transported molecules do not dissolve in the phospholipid bilayer. Instead, their passage is mediated by proteins that enable the transported molecules to cross the membrane without directly interacting with its hydrophobic interior.

Paper chromatography is a technique used to separate molecules based upon their size and solubility in a particular solvent. If
Tanya [424]

Answer:

a. Paper chromatography would separate the pigments into several bands that appear green or yellow/orange.

Explanation:

The primary or main pigment in plants is the chlorophyll. The chlorophyll gives plants their characteristics green colour and helps in the absorption of light during photosynthesis.

Other pigments in plants include carotenoid with its characteristic yellow, red or orange colour; anthocyanin with its re/blue colour and betalains with its red/yellow colour.

<em>Hence, if pigments from a particular species of plant are extracted and subjected to paper chromatography, one would expect the pigments to be separated into several colour bands ranging from green to yellow/orange.</em>

The correct option is a.
