Botany - Cell - The Unit of Life Question with Solution | TestHub
Assertion : Eukaryotic cells have the ability to adopt a variety of shapes and carry out directed movements. Reason: There are three principal types of protein filaments - microfilaments, microtubules and intermediate filaments, which constitute the cytoskeleton.
Options:
Answer:
Solution:
The cytoskeleton is a fibrous network made of proteins that contributes to the structure and internal organization of eukaryotic cells within the cytoplasm. It is a dynamic structure that maintains cell shape, enables some cell motion (using structures such as flagella and cilia), and plays important roles in both intra-cellular transport (the movement of vesicles and organelles, for example) and cellular division.The cytoskeleton has three major fibre types: microfilaments made of actin protein, intermediate filaments made of various kinds of proteins (eg keratin), and microtubules made of tubulin.
