Concept explainers
To discuss:
The structures and functions of lysosomes and peroxisomes and the similarities and differences between them.
Introduction:
Cells are regarded as the simplest unit (structural and functional) of life. Cellular membrane, nucleus, and cytoplasm are the three major components of a cell. Cellular membrane, which surrounds the entire cell, is composed of phospholipids and proteins. The nucleus is bound by a nuclear membrane, and it possesses the genetic material of the cell. Cytoplasm consists of organelles, cytoskeleton (filaments and tubules), and inclusion bodies. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus). Organelles are structures present within a cell and are specialized to perform a particular metabolic task essential for the survival of the cell. Organelles that are enclosed by a membrane are called as membranous organelles. For example, mitochondria and nucleus. Ribosomes and centrioles are organelles that are not bound by a membrane.
