Cell vocab

TermDefinition
Cell Cells are the basic building blocks of all living organisms. They are the smallest units of life and are responsible for carrying out all the functions necessary for an organism to survive and function properly.
Osmosis Osmosis is the process of water moving across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration.
Cell Theory Cell Theory, also known as the cell doctrine, is a fundamental concept in biology that states that all living organisms are composed of cells, and that cells are the basic structural and functional units of life.
Cell Wall The cell wall is a rigid structure that surrounds plant cells and provides support and protection.
Cell Membrane The cell membrane is a crucial component of all cells. It acts as a barrier, separating the interior of the cell from the external environment.
Nucleus The nucleus is a highly structured organelle found in eukaryotic cells. It contains the genetic material of the cell, including DNA, and is involved in various cellular processes such as gene expression, DNA replication, and RNA processing.
Organelle Organelles are specialized structures within cells that perform specific functions.
Ribosome Ribosomes are ancient molecular machines found in all living organisms that play a crucial role in protein synthesis.
Nucleic Acid Nucleic acids are natural biopolymers that store and transmit genetic information in living organisms.
Selectively Permeable Selective permeability refers to the property of a membrane or material to allow the passage of certain substances while restricting the passage of others.
Cytoplasm The cytoplasm is a gel-like environment inside cells that is composed of various molecules, organelles, and cytoskeletal networks.
Mitochondria Mitochondria are organelles found in cells that play a crucial role in various aspects of cellular function.
Endoplasmic Reticulum The endoplasmic reticulum (ER) is a vital organelle in cells responsible for various functions.
Golgi Apparatus The Golgi apparatus is a vital organelle in cells that is responsible for processing, sorting, and trafficking newly synthesized proteins and lipids.
Chloroplast Chloroplasts are organelles found in plant cells that are responsible for photosynthesis.
Lysosome Lysosomes are membrane-bound organelles within cells that are involved in the degradation and recycling of cellular waste.
DNA DNA, or deoxyribonucleic acid, is a molecule that contains the genetic instructions for life. It is made up of units called nucleotides, which consist of a sugar, a phosphate group, and a nitrogen base
Passive Transport Passive transport refers to the movement of molecules or particles across a cell membrane without the need for energy expenditure by the cell.
Active Transport Active transport is a process by which molecules are transported across a biological membrane against a concentration or electrochemical gradient, requiring energy.
Diffusion Diffusion is the process by which molecules or particles spread out from an area of high concentration to an area of low concentration.
Tissue Tissue is a term used to describe a group of cells that work together to perform a specific function in the body.
Organ The definition of an organ is a bit vague, but it is generally understood as a group of tissues that work together to perform a specific function in the body.
Organ System The human body is made up of multiple organ systems that work together to maintain overall health and function.
Endocytosis Endocytosis is a fundamental process in which cells internalize molecules and macromolecules from the extracellular environment.
Exocytosis Endocytosis is a fundamental process in which cells internalize molecules and macromolecules from the extracellular environment.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
