Chapter 2 Cells. Flashcards
Protective outer covering of all cells that regulates the interaction between the cell and environment.
Smallest unit of an organism that can carry on life functions.
States the all organisms are made of one or more cells, the cell is the basic unit of life,and all cells come from other cells.
Rigid structure that encloses, supports, and protects the cells of plants, algae, fungi, and most bacteria.
Green, chlorophyll-containing, plant-cell organelle that uses light energy to produce sugar from carbon dioxid and water.
Constantly moving gel-like mixture inside the cell membrane the constantly heredity material and is the location of most of a cell's life processes.
Cytoplasmic organelle that moves materials around I
in a cell and is made up of a complex series of folded membranes;can be rough (with attached ribosome) or smooth (without attached ribosomes).
Organelles that package cellular materials and transport them within the cell or out of the cell.
Living cell in which a virus can actively multiply or in which a virus can hide until activated by environmental stimuli.
Cell organelle that breaks down food and releases energy.
Organelles that controls all the activities of a cell and contains hereditary materials made of proteins and DNA.
Structure, such as the heart, made up of different types of tissues that all work together.
Structure in the cytoplasm of a eukaryotic cell that can act as a storage site, process energy, move materials, or manufacture substances.
Small cytoplasmic structure on which cells make their own proteins.
A group of similar cells that work together to do one job.
A stand of hereditary material surrounded by a protein coating.
