Students have asked these similar questions
ciliates regulate osmosis in their habitat by:
Macronuleus.
Cilia.
Micronucleus.
Oral groove.
Contractile vacuole.
This organelle allows molecules to enter and leave the cell. Also, supports and protects the cell
O cytoskeleton
cell membrane

- describe the structure and functions of microvilli, cilia,flagella, and pseudopodsarrow_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_forwardWhich cytoskeletal element mediates cell crawling?arrow_forward

- Which of the following statements is true about the Golgi bodies?arrow_forwardTreating cells with a drug that breaks apart tubulin dimers would disrupt all of the following EXCEPT movement of vesicles toward the cell membrane movement using cilia movement using bacteria flagella movement of vesicles toward the centrosomearrow_forwardWhich statement about the cytoskeleton is incorrect? Microtubules are hollow tubes of protein that provide structural support. Plant cells lack a cytoskeleton because they have a rigid cell wall. Intermediate filaments are more permanent structures in cells compared to microfilaments and microtubules. Microfilaments are chains of proteins that resist stretching. Components of the cytoskeleton are often involved with movement of organelles within the cytoplasm.arrow_forward
