Cells are the basic unit of life, and all living organisms are composed of cells. Cells vary in shapes and sizes, and contain specialized structures that perform specific functions. Cells are surrounded by a cell membrane, and contain organelles such as mitochondria and the nucleus.

Cell Theory - A scientific theory that states that all living things are composed of cells, that cells are the basic unit of life, and that all cells come from pre-existing cells. Cell Membrane - A thin, flexible layer that surrounds the cells of all living things and controls what enters and exits the cell. Organelles - Tiny structures within a cell that carry out specific functions, such as energy production and waste disposal.

The nucleus is the control center of a cell. It contains the genetic material, called DNA, which is responsible for controlling the cell's activities. The nucleus also regulates the cell's growth and reproduction.

Ribosomes are tiny organelles found in cells that help create proteins. They read the genetic code in messenger RNA and use it to assemble amino acids into a chain, which then folds into a functional protein. Ribosomes can be found floating free in the cytoplasm or attached to the endoplasmic reticulum.

The Endoplasmic Reticulum (ER) is a network of membrane-bound tubes and sacs that extend throughout the cytoplasm of eukaryotic cells. It plays an important role in protein synthesis, lipid metabolism, and calcium storage. The ER can be rough or smooth depending on the presence or absence of ribosomes on its surface.

The Golgi apparatus is an organelle found in eukaryotic cells that processes and packages proteins and lipids for transport to their final destination. It consists of flattened stacks of membranes called cisternae. The Golgi apparatus is essential for maintaining the proper function of the cell and plays a critical role in cellular communication.

Lysosomes are the recycling centers of the cell. They break down waste materials and cellular debris into smaller molecules that can be reused by the cell. Without lysosomes, cells would become filled with waste products and eventually stop functioning properly.

Mitochondria are organelles found in cells that produce energy through cellular respiration. They contain their own DNA and are thought to have originated from free-living bacteria that were engulfed by early eukaryotic cells. Mitochondria play a crucial role in metabolism and have been linked to various diseases.

Cells are the basic building blocks of all living organisms. There are two main types of cells, prokaryotic and eukaryotic. Prokaryotic cells, like bacteria, lack a nucleus and other membrane-bound organelles. Eukaryotic cells, like those in plants and animals, have a nucleus and various organelles that perform specific functions within the cell.

A prokaryotic cell is a type of cell that lacks a nucleus and other membrane-bound organelles. These cells are found in bacteria and archaea, and are often smaller and simpler in structure than eukaryotic cells. Prokaryotic cells have genetic material in the form of circular DNA, and can reproduce through binary fission.

Bacteria are microscopic organisms that exist everywhere on earth. They can be harmful, causing infections and diseases, but some strains of bacteria are necessary for human health and play important roles in food production and environmental processes. Bacteria reproduce via asexual reproduction Bacteria often have different organelles that allow for there function and survival, like flagella that allow some bacteria to move

Human cells contain enough DNA to stretch from one end of the Milky Way to the other over 100 times. Cells come in many shapes and sizes, with some as small as 0.2 micrometers. Cells can survive in extreme temperatures ranging from -272°C (-458°F) to 150°C (302°F).
