Question
Identify one advantage of phagocytosis in eukaryotes when compared with feeding in Bacteria.
Solution
One advantage of phagocytosis in eukaryotes when compared with feeding in bacteria is the ability to ingest larger particles or even entire cells.
Step 1: Understanding the terms Phagocytosis is a process used by eukaryotic cells (cells with a nucleus) to engulf a particle or cell in a vesicle, which then fuses with a lysosome to break down the material. Bacteria, on the other hand, are prokaryotes (cells without a nucleus) and they feed by absorbing nutrients through their cell wall.
Step 2: Comparing the processes In bacteria, the size of the particles they can absorb is limited by the size of the nutrient channels in their cell wall. In contrast, eukaryotic cells can change shape and surround larger particles or cells, engulfing them completely. This allows eukaryotes to feed on a wider variety of sources, including bacteria themselves.
Step 3: Identifying the advantage The advantage of phagocytosis in eukaryotes is therefore the ability to ingest larger particles or cells, providing a wider range of potential nutrient sources. This can be particularly beneficial in environments where nutrients are scarce or varied.

Which comparison would best support the idea presented in this paragraph?Through the process of phagocytosis, specialized cells in the immune system engulf and destroy unwanted microorganisms in the blood. This serves to remove foreign bodies and fight infection. These cells, called phagocytes, first surround the microorganisms and then begin a series of chemical reactions that break them down.A.Much like the process of digestion, the phagocytes "eat" and then digest the unwanted organisms.B.Acting like a cargo transport, the phagocytes move the unwanted organisms out of the body.C.The phagocytes act as tour guides, showing microorganisms where they need to reside.D.As if in a war, the phagocytes battle the microorganisms for control of the immune system.
