Answer:
In order for something to be classified as living, it must grow and develop, use energy, reproduce, be made of cells, respond to its environment, and adapt. While many things meet one or more of these criteria, a living thing must meet all of the criteria.
Plasma membrane is the structure which covers up the uptaken molecule.
<h3><u>Explanation:</u></h3>
Uptaking of nutrients from the surrounding needs to be very appropriate for the cell to obtain nutrition, as well as to maintain cell immunity. In case of simpler molecules like glucose etc, the molecules are taken inside the cell by means of specific channels or transport proteins. In case of complex molecules, cells prefer to perform endocytosis - either phagocytosis for solid ones, and pinocytosis for liquid ones.
When the cell finds something which can be taken in, it projects a fold of cell membrane towards the liquid which surrounds part of the liquid, or fully. This cell membrane then presents a depression which covers up the liquid. Then the margins of the depression come closer and ultimately fuse, leaving the liquid inside the cell enclosed with a part of cell membrane. This then fuses with a primary lysozome to form a digestive vacoule, a secondary lysozome, a residual body, and ultimately gets excreted off the cell.

Answer:
c. platelets - phagocytize
Explanation:
Platelets are blood cells also known as thrombocyte, that helps with blood clotting to stop bleeding. In the case of an injury that leads to blood vessel damage, signals are sent to the blood platelets, once the signals are sent, the platelets and other coagulation react to the blood vessel damage and they form they initiate a plug (clot) to fix the blood vessel damage.
The are usually not involved in phagocytosis, the phagocytes including macrophages, monocytes, granulocytes, and dendritic cells are involved in phagocytosis
