Concept explainers
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. Other organelles present in a cell include endoplasmic reticulum, ribosomes, Golgi complex, mitochondria, centrioles, peroxisomes, and lysosomes. Protoplasm denotes all living material that are present in the cell enclosed by the cellular membrane (inside and outside the nucleus).

Golgi bodies c. endoplasmic reticulum d. post-Golgi vesiclesarrow_forwardFigure 3.13 Why does the cis face of the Golgi not face the plasma membrane?arrow_forwardBoth lysosomes and vacuoles are endomembrane structures, yet they differ in terms of their functions. Comment.arrow_forward
- The cistrenal space of ER is continuous with prenuclear space between the two membranes of the nuclear envelope and can communicate with the internal spaces of the golgi complex and lysosome by means of _______ that shuttle between these structures.arrow_forwardEndoplasmic reticulum, mitochondria, and golgi bodies are structures in cell whose forms dictate their physical functions. Describe their function in relation to their structure.arrow_forwardDifference between endoplasmic reticulum and golgi apparatus?arrow_forward
