-microtubules

-microfilament

-intermediate filaments

2. Which transmembrane protein is connects the cytoskeleton to the ECM?

-integrin

-fibronectin

-collagen

3. Which type of cell junction do plant cells possess?

-plasmodesmata

-communication junctions

-tight junctions

-adhesion junctions

Answer 1

1. Microfilaments are the thinnest cytoskeleton fibers and are used for moving materials within cells.

Correct option is (b) Microfilament.

2. Integrins are transmembrane receptors that connect the extracellular matrix (ECM) to the cell cytoskeleton.

correct option is (a) integrin

3. Cell junction in animal cells include tight junction, gap junction and Adherens junction.

Whereas plant cells have only one type of cell junction, plasmodesmata.

correct option is (a) plasmodesmata
