The Cell

What Is A Cell, and What They All Share?!

The smallest structural and functional unit of an organism, typically microscopic and consisting of cytoplasm and a nucleus enclosed in a membrane. Microscopic organisms typically consist of a single cell, which is either eukaryotic or prokaryotic.

1. cell membrane
2. contain DNA
3. ribosomes
4. cytoplasm

What are Eukaryotes, and How They Reproduce?!

  1. An organism consisting of a cell or cells in which the genetic material is DNA in the form of chromosomes contained within a distinct nucleus. Eukaryotes include all living organisms other than the eubacteria and archaebacteria.

The life of eukaryotic cells is characterized by a cell cycle with two major phases: the interphase and cell division. During the interphase, the cell takes in nutrients, grows, and duplicates its chromosomes.

What Is A Prokaryote, and How They Reproduce?

A prokaryote is a single-celled organism that lacks a membrane-bound nucleus mitochondria, or any other membrane-bound organelle.

Prokaryotic cells reproduce by a process that is called binary fission. The DNA in such cells is contained in a single circular chromosome called a plasmid within the cytoplasm. The reproductive process starts with the replication of the chromosome.

Wow! Cells Are Weird!!!
