1.4 Kingdoms Flashcards
Kingdoms
One of the major groups into which all organisms are classified
Organic Substances
Substances whose molecules contain carbon; in biology we normally consider organic compounds to be ones that are made by living organisms
Chlorophyll
A green pigment (coloured substance) that absorbs energy from light; the energy is used to combine carbon dioxide with water and make glucose
Cellulose
A carbohydrate that forms long fibres and makes up the cell walls of plants
Fungus
An organism whose cells have cell walls, but that does not photosynthesis
Prokaryote
An organism whose cells do not have a nucleus
Protoctist
A single-celled organism, or one with several very similar cells
Hyphae
Microscopic threads, made of cells linked in a long line, that make up the body of a fungus
Decomposers
Organisms that break down organic substances outside their bodies, releasing nutrients from them that other organisms can use
Spores
Very small groups of cells surrounded by a protective wall, used in reproduction
Multicellular
Made of many cells
Unicellular
Made of a single cell
