Cell Theory

• Mitochondria are organelles found in the cells of all complex organisms that produce most of the cell's supply of adenosine triphosphate (ATP), which is the chemical energy currency of cells.
• Robert Hooke was an English scientist who coined the term "cell" to describe small compartments he observed under his microscope while studying cork bark.
• The cell theory has three main components: (1) All organisms are composed of one or more cells; (2) The cell is the structural and functional unit of all organisms; and (3) New cells arise only from existing cells.
• Cell theory states that all living things are made up of cells, which is the basic unit of life.
• Cells arise from pre-existing cells through cell division.
• Ribosomes are complexes of RNA and protein located in the cytoplasm that synthesize proteins in the cell, with the help of transfer RNA.
• Ribosomes are small structures made up of proteins and RNA molecules that function as sites of protein synthesis in cells.
• The endoplasmic reticulum (ER) is an interconnected network of membranes within eukaryotic cells, involved in protein synthesis, lipid metabolism, detoxification, calcium storage, and drug resistance.
• Lysosomes are membrane-bound vesicles containing digestive enzymes that break down waste materials and foreign substances inside cells.
• The first person to use the word 'protoplasm' was Matthias Schleiden, a German botanist.
• Cells can be classified into two types based on their structure: prokaryotic and eukaryotic.
• Schleiden proposed that plants were made up of tiny units called protoplasts, which contained a jelly-like substance called protoplasm.
• All cells come from pre-existing cells through division.
• Prokaryotes have no nucleus, whereas eukaryotes do.
• Matthias Jakob Schleiden was a German botanist known for his contributions to plant physiology and histology.
• A cell can be defined as the smallest unit of structure and function in living organisms.
• There are two types of cells: prokaryotic and eukaryotic.
• All cells contain hereditary information in the form of DNA.
• Robert Hooke coined the term "cell" when he observed cork under a microscope and saw small chambers resembling monks' rooms (or cells).
• Plant cells differ from animal cells in their size, shape, and presence of chloroplasts.
• Hooke believed that these structures were responsible for the growth of plants but later discovered they were not alive.

• The first person to propose the idea of cell theory was Robert Hooke.
• Cell theory states that all organisms are composed of one or more cells, that the cell is the basic structural and functional unit of life, and that new cells arise only from existing cells.
• Cells are the basic building blocks of life and perform various functions such as metabolism, growth, reproduction, response to stimuli, and movement.
• Robert Hooke coined the term "cell" when he observed thin sections of cork under a microscope and saw small chambers resembling monks' rooms (Latin word "cella").
• The cell theory states that all living things are composed of one or more cells, cells arise only from preexisting cells, and all cells contain hereditary information.
• Ribosomes synthesize proteins using instructions provided by DNA or RNA.
• He named these structures "cellulae," meaning little rooms.
• Mitochondria are responsible for cellular respiration and energy production.
• Hooke observed small chambers or compartments within the cork tissue he studied.
• The cell theory states that all living things are made up of one or more cells, cells come from pre-existing cells, and all cells are similar in nature.
• Cells are the basic building blocks of life and perform various functions such as growth, reproduction, metabolism, response to stimuli, and movement.
• Cells are the basic building blocks of life and perform various functions such as growth, reproduction, metabolism, response to stimuli, and movement.
• Animal cells have a nucleus surrounded by nuclear envelope, while plant cells have a large central vacuole with a nucleus located near the periphery.
• Animal cells have a nucleus surrounded by nuclear envelope, while plant cells have a large central vacuole with a nucleus located near the periphery.
• The discovery of bacteria by Anton van Leeuwenhoek led to the realization that there was more life on Earth than previously thought.
• The cell theory states that all organisms are composed of one or more cells, that all cells come from pre-existing cells, and that cells are the basic units of life.
