Cell division

Cell division is a special biological process by which a cell gets divided into two or more new cells. During cell division, a cell’s nucleus splits up and the DNA is replicated. There are broadly two types of cell division : mitosis and meiosis.Most of the time when we refer to “cell division”, we mean mitosis, a process of making new body cells. Where meiosis is the separate type of cell division that only creates eggs and sperm cells. Because this mitosis cell division is so critical, Read more [...]

Cell Organelles

Brief introduction to cell organelles : Living beings are made up of cells. Some organisms consists of just single cell, while others are made up of trillions of cells. Each of these cells functions as a tiny factory, with its individual parts which work together to keep the cell alive and also in turn keep the organism going. These parts are called organelles.There are mainly two types or categories of cells: prokaryotic and eukaryotic cells. Both of these types of cells have a several things Read more [...]

Difference between prokaryotes and Eukaryotes

Even though at very elemental level, all of the cells require the same functions to survive, yet the significant differences between prokaryotes and eukaryotes includes structural differences and in replication process. Most noteworthy is lack of nucleus in the bacteria and archaean – the two types of prokaryotic cells.Prokaryotes : Are almost similar Do not contain any membrane enclosed organelles Replicates via process of binary fission Lacks histones Read more [...]

Prokaryotes and Eukaryotes

Prokaryotes and Eukaryotes Prokaryotes : Prokaryotes does not contains an organized nucleus. Their DNA is  the kind of floating around its cell. The DNA is clumped up, but not inside of the nucleus.Prokaryotes are single cell organisms. Most prokaryotes are bacteria and it is important to know that bacteria can do some amazing things. Although bacteria are very simple organisms, they can be found everywhere on the planet. It is also thinked by some scientists Read more [...]

Difference between plant cell and animal cell

Key Difference : Animal cells doesn’t contains rigid cell walls and the chloroplasts, and also they have smaller vacuoles. While plant cells have a rigid cell wall, have chloroplasts and have a much larger central vacuole.Cells are smallest unit of life and microscopic by nature, which means we cannot see them with our naked eye. These cells were discovered in 1665 by the Robert Hooke and were named after the small “cells” (or rooms) in a monastery. There are basically two types of Read more [...]

Cell?

What is Cell? CELL is the structural and functional unit of all living organisms. Each and every organism on Earth is divided into cells. It is the smallest and basic structural unit of all organism. You can think a cell of a small compartment that keep holds all the biological equipments necessary to keep an organism alive and successful. Living things may be either single celled or they can be very much complex, for instance human being – the most complex living creature, yet made Read more [...]
