|
Respiration |
The chemical reactions in cells that breakdown nutrient molecules and release energy for metabolism |
|
|
|
Sensitivity |
The ability to detect or sense stimuli in the internal or external environment and to make appropriate responses |
|
|
|
Nutrition |
The taking in of materials for energy, growth and development -Plants require light, carbon dioxide, water and ions -Animals need organic compounds and ions and usually water |
|
|
|
Growth |
A permanent increase in size and dry mass by an increase in cell number or cell size or both |
|
|
|
Excretion |
Removal from organisms of the waste products of metabolism, toxic materials, and substances in excess of requirements |
|
|
|
Reproduction |
The processes that make more of the same kind of organisms |
|
|
|
Classification |
The science of placing organisms into categories on the basis of their observable characteristics |
Based on morphology and anatomy |
|
|
List the hierarchy of classification |
Kingdom Phylum Class Order Family Genus Species |
|
|
|
List the 5 kingdoms |
Animalia Plantae Protoctistans Prokaryote Fungi |
|
|
|
List two modern methods of classification |
Protein structure DNA structure |
|
|
|
Protein structure |
Organisms closely-related have very similar amino acid sequences in proteins such as haemoglobin |
|
|
|
DNA structure |
Closely-related organisms have very similar base sequences in DNA because there is less evolutionary time for mitigation to change these sequences |
|
|
|
Species |
A group of organisms that can reproduce and produce fertile offspring |
|
|
|
Binomial system |
An internationally agreed system in which the scientific name of an organism is made up of two parts: genus and species |
|
|
|
List the features of all living cells |
Cytoplasm Cell membrane DNA as genetic material Ribosomes for protein synthesis Enzymes involved in respiration |
|
|
|
Features of the Plant Kingdom |
Cellulose cell wall Light absorbing pigment, chlorophyll |
|
|
|
Photosynthesis |
The process by which plants manufacture food molecules from simple, organic sources using light as a source of energy |
|
|
|
Phyla of the Plant Kingdom |
Algae Mosses Ferns Seed plants |
|
|
|
Ferns |
Have roots, steme and complex leaves and vascular tissues Able to produce spores for wide dispersal Do not have thick cuticles Can only survive in shady, humid areas |
|
|
|
Angiosperms |
Plants with enclosed seeds Flowers Large leaf surfaces allow high rate of photosynthesis and diffusion Ovary protects ovules/embryo from drying out Fruits Stomata regulate loss of water vapour and exchange of gases Vascular system transports water, ions and organic solutes Extensive root system anchor the shoot system and absorb water and ions |
|
|
|
Two groups of angiosperms |
Monocotyledons Dicotyledons (eudicotyledons) |
|
|
|
Monocotyledons |
One cotyledon One seed leaf Parallel veins |
|
|
|
Dicotyledons |
Two cotyledons Two seed leaves Branched veins |
|
|
