Molecules to Structures: Cells Terms Flashcards
Having, made up of, or involving more than one and usually many cells.
Multicellular
Consisting of a single cell.
Unicellular
A group of cells that have similar structure and that function together as a unit
Tissues
A collection of tissues that structurally form a functional unit specialized to perform a particular function
Organ
A complex network which connects several biologically relevant entities.
System
The systematic organization of organisms into levels
Organism Hierarchy
Unicellular microorganisms which have cell walls but lack organelles and an organized nucleus. {Prokaryotic}
Bacteria
A group of organisms of one species that live and interact closely with each other.
Colonies
Unicellular eukaryotes that belong to the Kingdom of Fungi
Yeast
Organisms whose cells lack a nucleus and other organelles. Most prokaryotes are small, single-celled organisms that have a relatively simple structure.
Prokaryote
Any cell or organism that possesses a clearly defined nucleus.
Eukaryote
Make (something) appear larger than it is
Magnify
An optical instrument used for viewing very small objects, such as mineral samples or animal or plant cells
Microscope
Deoxyribonucleic Acid. Molecule that contains the genetic code that is unique to every individual.
DNA
The membrane structure in a cell that contains the chromosomes.
Nucleus
The firm nonliving layer that encloses and supports the cells of most plants, bacteria, fungi, and algae.
Cell Wall
Phospholipid bilayer that is semipermeable and separates the interior of the cell from the outside environment.
Cell Membrane
Group of predominantly aquatic, photosynthetic, and nucleus-bearing organisms that lack the true roots, stems & leaves.
Algae
Organelle within the cells of plants and certain algae that is the site of photosynthesis.
Chloroplast
Found in the nucleus of each cell. The thread-like structure that contains the DNA molecule.
Chromosomes
A membrane-bound cell organelle that generate most of the chemical energy needed to power the cell.
Mitochondria
The natural movement of particles from an area of higher concentration to an area of lower concentration.
Diffusion
The movement of water molecules from a solution with a high concentration of water molecules to a solution with a lower concentration of water molecules.
Osmosis
A chemical process that occurs in plants, algae, and some types of bacteria, when they are exposed to sunlight. In this process, water and carbon dioxide combine to form carbohydrates (sugars) and give off oxygen.
Photosynthesis
