ch 1 - species classification Flashcards
a living thing
organism
organisms begin small and get larger. this is:
growth
organisms are able to change their position, shape, or place. this is:
movement
organisms pick up information about changes in their environments and can react to it. this is:
sensitivity
organisms produce fluids and waste as a result of metabolic reactions. this is:
excretion
organisms are able to create new organisms of the same species as themselves. this is:
reproduction
organisms use substances in their environment to provide them with energy. this is:
nutrition
organisms break down glucose and other substances inside their cells to release energy that they can use. this is:
respiration
the chemical reactions that take place in living organisms
metabolic reactions
the mass of an organism after it has been killed and all water removed from it
dry mass
a species that lived in the past, and is thought to have been related to several different species alive today.
common ancestor
a green pigment that absorbs energy from sunlight; the energy is used to combine carbon dioxide with water and create glucose
chlorophyll
a carbohydrate that forms long fibres and forms the cell wall of plants
cellulose
organisms that break down organic substances outside their bodies , releasing nutrients from them that other organisms can use
decomposers
very small groups of cells surrounded by a protective wall, used in reproduction
spores
made of many cells
multicellular
made of a single cell
unicellular
seven characteristics that all organisms show
movement, respiration, sensitivity, growth, reproduction, excretion, and nutrition
the universal, latin name for a species. it’s the genus name capitalized and the species name
binomial naming system
a kind of chart of pairs of contrasting statements or questions. you work through the chart until it leads you to the name of the species you are trying to identify
dichotomous key
the large group of species whose cells have cell walls made of cellulose, and some of their cells have chloroplasts.
the plant kingdom
the 5 kingdoms; they differ in the structure of their cells
plants, animals, fungus, prokaryote, and protoctist
animals with backbones
vertebrates: fish, amphibians, reptiles, birds, and mammals
monocots or dicots
flowering plants
