NCERT Solutions For Class 11 Biology Chapter 8: Chapter Description
All organisms are made of cells. Cells vary in their shape, size and activities/functions. Based on the presence or absence of a membrane-bound nucleus and other organelles, organisms can be classified as eukaryotic or prokaryotic. A typical eukaryotic cell consists of a cell membrane, nucleus, and cytoplasm. A prokaryotic cell, on the other hand, doesn’t have a nucleus and have freely-floating genetic materials. Plant cells have a cell wall outside the cell membrane. The plasma membrane is selectively permeable and facilitates the transport of several molecules.
In this chapter, students will learn about the various constituents of the cell. This is a medium weightage chapter from which about 2-4 questions are asked every year.
Important Topics: Cell Theory, Ultrastructure of Prokaryotic and Eukaryotic Cell.
Important Concepts: Cell Size, Prokaryotic Cell and its organization, tools, and techniques for cell study, Membrane Organisation, Endoplasmic Reticulum and Mitochondria.
