Parts Of The Cell Flashcards
What is the cell membrane?
The cell membrane is a protective barrier that encloses a cell. It separates the cell’s contents from the cell’s environment.
What is the cell wall?
The cell wall is a rigid structure that gives support to the cell and is made of a complex sugar called cellulose.
What are ribosomes?
Organelles that make proteins are called ribosomes. They are the smallest organelles in a cell.
What is endoplasmic reticulum?
The endoplasmic reticulum, or ER, is a system of folded membranes in which proteins, lipids, and other materials are made.
The ER is part of the internal delivery system of the cell. Its folded membrane contains many tubes and passageways. Substances move through the ER to different places in the cell.
What is mitochondria?
Mitochondria
A mitochondrion is the main power source of a cell. A mitochondrion is the organelle in which sugar is broken down to produce energy. Energy released by mitochondria is stored in a substance called ATP (adenosine triphosphate).
What are chromoplasts?
Chloroplasts are organelles in plant and algae cells in which photosynthesis takes place.
What is the Golgi body complex?
The organelle that packages and distributes proteins is called the Golgi complex .It is named after Camillo Golgi, the Italian scientist who first identified the organelle.
What are lysosomes?
Lysosomes are vesicles that are responsible for digestion inside a cell. Lysosomes are organelles that contain digestive enzymes. They destroy worn-out or damaged organelles, get rid of waste materials, and protect the cell from foreign invaders. Lysosomes come in a wide variety of sizes and shapes.
What is a large central vacuole ?
They store digestive enzymes and aid in digestion within the cell. The large central vacuole in plant cells stores water and other liquids. Large central vacuoles that are full of water help support the cell. Some plants wilt when their large central vacuoles lose water.
What is a nucleus?
It contains the cell’s DNA, or genetic material. DNA contains the information on how to make a cell’s proteins. Proteins control the chemical reactions in a cell. They also provide structural support for cells and tissues.
