Question 7How does an Amoeba obtain its food?

Question

Bright Tutorials · Accepted Answer

The flexibility of the cell membrane enables Amoeba to obtain its food through a process known as endocytosis. It uses pseudopodia, temporary extensions of its cell membrane, to surround and engulf its food. The engulfed particles are then enclosed in a food vacuole, where digestion takes place.

        Cell theory: all organisms made of cells; cell = basic unit; cells from pre-existing cells
Prokaryotic (no nuclear membrane, bacteria) vs Eukaryotic (true nucleus, plants/animals)
Plasma membrane: selectively permeable, lipid bilayer
Osmosis: water from dilute → concentrated through semipermeable membrane
Organelles: Nucleus (control), Mitochondria (powerhouse), ER (transport), Golgi (packaging), Lysosomes (suicide bags), Plastids (photosynthesis), Vacuoles (storage)
Plant cell: cell wall, large vacuole, plastids present. Animal cell: no cell wall, centrioles present
