A Comprehensive Guide To Cell: The Unit Of Life Neet Questions
The National Eligibility cum Entrance Test (NEET) is an entrance exam conducted by the National Testing Agency (NTA). It is one of the most important exams for students aspiring to pursue a medical career. To crack the NEET exam, it is essential to have a thorough understanding of the subject, ‘Cell: The Unit of Life’. This article will provide a comprehensive guide to Cell: The Unit of Life NEET questions and help aspiring medical students to crack the exam.
Types of Cells:
Cell is the basic unit of life and all living organisms are composed of cells. There are two types of cells – prokaryotic and eukaryotic. Prokaryotic cells are single-celled organisms and do not have a nucleus or any other membrane-bound organelles. Eukaryotic cells, on the other hand, are multi-celled organisms and contain a nucleus, mitochondria, endoplasmic reticulum, Golgi apparatus and other membrane-bound organelles.
Cell Structure and Function:
Cell structure and function are closely related. The structure of the cell helps it to perform its functions. Cells are made up of cytoplasm and a cell membrane which is composed of lipids and proteins. The nucleus is a spherical organelle and contains genetic material. Other organelles, such as the mitochondria, ribosomes, Golgi apparatus and endoplasmic reticulum, are responsible for the metabolism and synthesis of proteins.
Cell division is the process by which cells reproduce themselves. There are two types of cell division – mitosis and meiosis. Mitosis is the process of cell division in which the parent cell divides into two daughter cells. Meiosis is the process of cell division in which the parent cell divides into four daughter cells.
The cell cycle is the process by which cells grow and divide. It can be divided into four phases – G1, S, G2, and M. During the G1 phase, the cell grows and prepares for DNA replication. The S phase is the DNA replication phase. During the G2 phase, the cell prepares for mitosis. The M phase is the mitosis phase in which the cell divides into two daughter cells.
The above article provides a comprehensive guide to the Cell: The Unit of Life NEET questions. It is important to have a thorough understanding of the subject to crack the exam. With the help of this guide, students can gain an insight into the structure, function and division of cells, as well as the cell cycle. With regular practice, students can easily ace the exam.
