This process is called photosynthesis. Cytoplasm is the gel-like material inside the cell membrane and. outside the nucleus. Cytoplasm contains a large amount of water and many chemicals. and structures that carry out the life processes in the cell. These. structures that the cytoplasm contains are called organelles.
Macrophages (Greek: big eaters, from Greek Î¼Î±ÎºÏÎ¿Ï (makros) = large, ÏÎ±Î³ÎµÎ¹Î½ (phagein) = to eat) are a type of white blood cell that engulfs and digests cellular debris, foreign substances, microbes, cancer cells, and anything else that does not have the types of proteins specific to healthy body cells on its surface in a process called phagocytosis.
A macrophage can usually engulf the tuberculosis bacterium, but then the bacterium has a means for preventing the lysosomes from fusing with the phagosome. If the macrophage is not activated by paracrines from a specific immune response, the bacteria may remain alive for long periods within the macrophage.
