When a cell uses ATP energy to transport a substance through a cell membrane from an area of lower concentration to an area of higher concentration, the cell is using

ACTIVE TRANSPORT

Explanation:

Generally, the transport of molecules across membranes can either be ACTIVE OR PASSIVE. Active transport are those transport that occurs against a concentration gradient i.e. from an area of low concentration of the substance to an area of high concentration, hence, will require energy input in form of ATP.

On the other hand, passive transport occurs down a concentration gradient and hence do not require energy to take place. Hence, based on the description above, when a cell uses ATP energy to transport a substance through a cell membrane from an area of lower concentration to an area of higher concentration, the cell is using ACTIVE TRANSPORT.

hey bro i looked it up on google the structure of the eye-spot in euglena viridie, e. ehrenbergii, and phacus pyriyorme is not as franzé haa described it. the so-called “crystal body” and “lens bodies” were not found in any of the individuals of the species examined by me. as earlier observers have stated, the eye-spot consists simply of a mass of pigment granules arranged in a single layer, and probably embedded in a protoplasmic framework, but the latter could not be seen, and its presence was only inferred from the fact that the pigment granules must be held together in some way, thd the eye-spot as a whole is capable of expansion, and that the pigment granules can be separated from each other.
