- Cilia and flagella have several functions. These include (choose all that apply) they have many functions, but they are found only on eukaryote organisms O membrane transport proteins embedded in the cell membranes of prokaryote organisms a means of creating a current in the mucous layer surrounding lung cells V a means of locomotionarrow_forwardWhich of the following is true of the flagellum in eukaryotes? It is a long, thin extracellular (exterior) structure, with a basal motor embedded in the cell membrane/cell wall. It is identical to the archaeal flagellum (archaellum) in composition and structure, but very different in composition and structure from bacterial flagella. It is a long, thin structure containing bundles of microtubules and motor proteins, all within the plasma membrane. Eukaryotic cells do not possess flagella.arrow_forwardFigure 4.2 Which of the following terms best describes the cell in Figure 4.2? axial filament O lophotrichous flagella O monotrichous flagellum O peritrichous flagella O amphitrichous flagellaarrow_forward
- In observing a cell, you note the presence of flagella. What could you look for to distinguish this specimen between a prokaryotic cell and an animal cell? Group of answer choices Confirm the presence or absence of a plasma membrane. Confirm the presence of a cell wall. Confirm the presence or absence of a nucleus. Confirm the presence or absence of ribosomes.arrow_forwardWhich of these organelles is directly involved in the motility of cells, either by moving substances past a cell which is fixed in place, or moving the cell itself within a liquid environment? Mark all that apply. Group of answer choices cilia flagella free ribosomes Golgi complex (Golgi apparatus) lysosomes mitochondria peroxisomes proteasomes rough endoplasmic reticulum smooth endoplasmic reticulum spliceosomesarrow_forwardA cell is characterized by the presence of a nucleus, many green organelles, a large water-filled vacuole, and a rigid cell wall. Therefore, it is an example of a cell. prokaryotic animal plant probetarrow_forward

When you examine cells that have taken up the virus, you find virus particles inside clathrin-coated vesicles. What membrane transport mechanismis the virus using to get inside the bat cells? Diatoms are protists that have complex glassy structures in their cell walls. These structures form within the Golgi apparatus. How do these structures reach the cell wall without having to pass through the plasma membrane?
