Quiz Review on the Cell Theory

Cells are basic units of structure and function in living things. This means that cells form the parts or an organism and carry out all of the an organism's processes, or functions.

The parts of the cell that are organized for specific functions are called organelles. The organelles include such structures as the nucleus and the mitochondria. The nucleus contains the genetic material and the mitochondria convert energy.

Nucleus. nucleus; animal cell. ... Ribosomes. Ribosomes are the protein factories of the cell. ... Endoplasmic reticulum. ... Golgi apparatus. ... Chloroplasts. ... Mitochondria

The plant cell has a cell wall, chloroplasts, plastids, and a central vacuole—structures not found in animal cells. Plant cells do not have lysosomes or centrosomes.

A vacuole is the storage area of the cell. Vacuoles store water, food, and waste.

A lysosome is a membrane-bound cell organelle that contains digestive enzymes. Lysosomes are involved with various cell processes. They break down excess or worn-out cell parts. They may be used to destroy invading viruses and bacteria.

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Often call the "power house of the cell"!

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function. Unicellular organisms include bacteria, protists, and yeast.

A rigid layer that gives protection, support, and shape to the cell. The cell wall forms protection to one cell, while the cell membrane controls the passage of materials into and out of a cell.
