Chapter 1- Classification of living organisms Flashcards
Provide the definition for movement.
An action by an organism or a part of on organism, that results in a change of place or position.
Provide the definition for excretion.
The removal of waste products of metabolism, or substances in excess of requirements.
Provide the definition for reproduction
The process that makes more of the same organism.
Provide the definition for respiration.
Respiration is the process of breaking down nutrient molecules to release energy for metabolism.
Provide the definition for sensitivity?
The responsiveness and ability to detect changes in the internal and external environment.
Provide the definition for growth?
Permanent increase in size and dry mass.
Provide the definition for excretion
The removal of waste products of metabolism or substances in excess or requirements.
What are viruses?
They cause common diseases, like cold, or more serious ones, like coronavirus. They aren’t considered to be living, beings, as they don’t exist unless, they are part of a hosts cell and don’t display the seven living characteristics. In a host cell they can take over the cells machinery to reproduce themselves. These new viruses burst out, and the process repeats. Host cell is usually killed.
What are species?
group of organisms that can reporduced to produce fertil organisms.
What is the bionomial system?
The first name in the bionomial system is the genus. These are gorpup of species that similiar faetures and common ancestor . The first letter is always capital.
what are characteristic features of animals and plants
Animals: Ther cells have a nuclues, but no cell wallo chlorplast, they feed n organic susbstancesmade by other living organism.s
Plants:
The feed by photosynthesis, their cells have a nuclues and cell walls made by cellulose, they often conain chlroplasts.
What are invertebrates?
They have no back bone, jointed legs, body is covered by exoskeleted made of chitin, segemented body.
Insects:
Head, thorax abdomen, 3 pairsof legs, 1 pair of attenai, 2 pairs of wings, breathing holes called sphiracles.
Arachnids: cephalothorax and abdomen and there are 4 pairs of joinet legs. The gills are called book lungs.
Crustaceans- chepahlothoraz and abdomen
joinet legs- 5 or more pairs, 2 pair of attenae, fills.
Myria pods- body divided into many heads and many segments
amin parid of legs, 1 pair of atenae’s breahthing holes called spiracles connected to taceha.
What are monocots and dicots?
Monocots
Fibrous root system
parallel venation with narrow leaves
flowers are in threes one cotlyon in seed.
Dicot
Tab root system
broad leaves form brandched veing
flower parts in 4’s and 5’s
two cotyledons formse
WWhat are protctists
- unicelllar, but soe like seewead are multicellurar
all cells have a nucleus
some have plant like cells with chloroplasts and cells walls,
other have animal liek cells.
What are fungi
Body made up of filaments called hypae, cell walls are not mad eup cellulose, saphrytes or parasitses.
