Resolution
The ability to distinguish two separate points or objects as distinct.
Anton van Leeuwenhoek
The inventor of the compound microscope.
Compound Microscope
A microscope that uses light to magnify objects and can magnify 400 to 1000 times.
Transmission Electron Microscope
A microscope that uses a beam of electrons to magnify the specimen and can magnify up to 600,000 times.
Scanning Electron Microscope
A microscope where a beam of electrons passes over the specimen and projects a 3D image onto a computer.
Atoms
Groups of protons, electrons, and neutrons.
Molecules
Groups of atoms bonded together.
Organelles
Specialized parts of cells that perform specific functions.
Cells
The smallest unit of life.
Tissues
Groups of similar cells.
Organs
Groups of tissues with a specific function.
Systems
Groups of organs that work together to perform a specific purpose.
Organisms
A single lifeform.
Cell
The smallest functional unit of life, and all living things are composed of cells.
Reproduce
The ability of living things to produce offspring.
Need energy
Living things require energy to carry out their functions.
Produce wastes
Living things generate waste products that need to be eliminated.
Grow
Living things have the ability to increase in size or develop.
Respond and adapt to their environment
Living things can sense and respond to changes in their surroundings.
The Cell Theory
The theory that all organisms are composed of one or more cells, the cell is the smallest functional unit of life, and all cells are produced from other cells.
Prokaryotic
One of the two types of cells, characterized by the absence of a nucleus and other membrane-bound organelles.
Eukaryotic
One of the two types of cells, characterized by the presence of a nucleus and other membrane-bound organelles.
Bacteria
Prokaryotic cells that are commonly found in various environments.
Plasmid
A circular piece of DNA found in prokaryotic cells.
Recombinant DNA
DNA that has been artificially combined from different sources.
Chromosome
A structure in the cell nucleus that contains genetic information.
Nucleus
The control center of the cell that contains DNA and regulates cell activities.
Nucleolus
A structure inside the nucleus that produces RNA and ribosomes.
Chromatin
The mass of stringy, entangled chromosomes observed during interphase.
Nucleoplasm
The jelly-like fluid inside the nucleus that supports its contents.
Cytoplasm
The gel-like substance inside the cell that suspends organelles and dissolves nutrients.
Mitochondrion
An organelle that is the powerhouse of the cell and produces ATP through cellular respiration.
Vacuole
A hollow organelle used for storage within the cell, containing water, nutrients, and waste.
Ribosomes
Small organelles responsible for protein synthesis.
Endoplasmic Reticulum (ER)
A network of tubes and canals throughout the cell that provides intracellular transport of molecules.
