Flashcards in CLASSIFICATION Deck (41)
What are the characteristics of living organisms ?
Definition of MOVEMENT
An action by an organism or a part of an organism causing a change in position or place
the chemical reactions that break down nutrient molecules in living cells to release energy for metabolism
The ability to detect or sense stimuli in the internal or external environment and to make appropriate responses.
A permanent increase in size and dry mass by an increase in cell number or cell size or both
The process that makes more of the same kind of an organism
The removal from organisms of toxic materials, the waste products of metabolism and substances in excess of requirements
the taking in of materials form energy, growth, and development; plants require light, carbon dioxide ,water and ions; animals need organic compounds and ions and usually need water
What is METABOLISM
Metabolism is a series of processes that control how your body uses energy
A species is defined as a group of organisms that can reproduce to produce fertile offsprings
What is the sequence of classification of LINNAEUS'S SYSTEM OF CLASSIFICATION
King Philip Came Over For a Good Spaghetti
What is MORPHOLOGY
What is ANATOMY
Morphology- overall form and shape of their bodies
Anatomy - the detailed body structure determined after dissection
Full form of DNA
What is DNA?
DNA is the chemical from which chromosomes are made. It is the genetic material passed on from generation to generation.
What is DNA made of?
DNA molecule is made up of strings are smaller molecules, containing four different bases. The bases, called A, C, G and T.
What makes two species more closely related in terms of DNA?
The more similar the basic sequences in the DNA of two species, the more closely related those two species are
What are the cell structures that all the cells of living organisms contain?
Cell membrane and
DNA as a genetic material (either found in the nucleus or free inside of cytoplasm).
Ribosomes ( for protein synthesis)
Enzymes ( for respiration)
FOUND WHEN BOTH VIEWED UNDER ELECTRON MICROSCOPE
Write cell structures that are only found in a typical plant cell?
What are the five Kingdoms?
What are the main features of all animals?
Their cells contain a nucleus but no cell wall or chloroplasts
The feed on organic substances made by other living things
Note: do not forget to look at the diagrams in the book
What are the main features of all plants ?
The cell contains a nucleus, chloroplasts and cellulose cell walls
They all feed by photosynthesis
Recall the main features of all fungi. Also give examples?
Cell walls- not made of cellulose
Do not have chlorophyll
Do not photosynthesise- feed by saprophytic (on dead or decaying material) or parasitic (and living material) nutrition
Examples-mushrooms, yeast, moulds
Write down the main features of all protoctists. Also give examples
Unicellular or multicellular
May or may not have cell wall and chloroplast
Some feed by photosynthesis and others feed on organic substances made by other living things.
- amoeba, paramecium and plasmodium
Main features of prokaryotes.
Have no nucleus
Has cell walls not made of cellulose
Have no mitochondria
examples- bacteria and blue/green algae
Write down three features of viruses
1.Viruses are not considered living things
2. They do not carry out Seven Life processes , instead they take over a host cells metabolic pathways in order to make multiple copies of themselves
3. Virus structure is simply genetic material (RNA or DNA) inside a protein coat
What are vertebrates and right the five classes of vertebrates.
All words vertebrates have a backbone.
Write down the main features of mammals
Fur/hair on skin
Young feed on milk from mammary glands
Heart has four Chambers
Have different types of teeth
Write down the main features of birds.
Skin covered in feathers
have two legs and a pair of wings
Lays hard shelled eggs
Have a beak
Heart has four Chambers
What are the main features of reptiles and give examples
Dry, fixed scales on skin
Lays rubbery shelled eggs on land
