NEET BIOLOGY

Detailed explanation-1: -Endoplasmic reticulum is an organelle found in both eukaryotic animal and plant cells. It often appears as two interconnected sub-compartments, namely rough ER and smooth ER. Both types consist of membrane enclosed, interconnected flattened tubes.

Detailed explanation-2: -The cytoskeleton is a complex dynamic network of filamentous structures present in the cytoplasm. It is made of microtubules, microfilaments, and intermediate filaments. The cytoskeleton is not organelles. They are proteinaceous structural elements that provide mechanical support and also maintain cell shape.

Detailed explanation-3: -The cytoskeleton is a structure that helps cells maintain their shape and internal organization, and it also provides mechanical support that enables cells to carry out essential functions like division and movement.

Detailed explanation-4: -The Cytoskeleton is also responsible for the movement of the cell though its environment, or the movement (or “wafting”) of part of its environment past the cell. This is done by the organelles Undulipodia, Cilia, and Flagella.

Detailed explanation-5: -Among all the functional components of a living cell, cytoskeleton is considered to be the backbone of a cell as it provides the cell its shape and structure (7). It is pivotal in controlling inter-and intracellular transportation and also plays an important role during cell division and differentiation (1).
