Biology KS5

Objectives and aims:

Our Biology KS5 solution meets the needs to develop understanding, skills and knowledge required for students at KS5 level. We incorporate fun and intriguing technologies to teach some of the hardest science concepts. Our teaching methodologies ensure students grasp key science ideas and principles without having to laboriously memorise the scientific rules and laws.

Our Biology KS5 Solution is tailored to ensure students develop appropriate balance between plant biology, animal biology and microbiology. Most students develop enthusiasm in further study and careers associated with biology and we support with such development. Living organisms including plants, animals and microorganisms interact with each other. There are fundamental similarities as well as differences between plants, animals and microorganisms. Students develop appreciation of such relationship between living organism in harmonious ecosystem and grow understanding of the relevance of sustainability to all aspects of scientific development.

Biology KS5 Contents:

Biodiversity:

  • the variety of life, both past and present, is extensive, but the biochemical basis of
    life is similar for all living things
  • biodiversity refers to the variety and complexity of life and may be considered at
    different levels
  • biodiversity can be measured, for example within a habitat or at the genetic level
  • classification is a means of organising the variety of life based on relationships
    between organisms and is built around the concept of species
  • originally classification systems were based on observable features but more
    recent approaches draw on a wider range of evidence to clarify relationships
    between organisms
  • adaptations of organisms to their environments can be behavioural, physiological
    and anatomical
  • adaptation and selection are major factors in evolution and make a significant
    contribution to the diversity of living organisms

Exchange and transport:

  • organisms need to exchange substances selectively with their environment and this takes place at exchange surfaces
  • factors such as size or metabolic rate affect the requirements of organisms and this
    gives rise to adaptations such as specialised exchange surfaces and mass
    transport systems
  • substances are exchanged by passive or active transport across exchange
    surfaces
  • the structure of the plasma membrane enables control of the passage of
    substances into and out of cells

Cells:

  • the cell theory is a unifying concept in biology
  • prokaryotic and eukaryotic cells can be distinguished on the basis of their structure
    and ultrastructure
  • in complex multicellular organisms cells are organised into tissues, tissues into
    organs and organs into systems
  • during the cell cycle genetic information is copied and passed to daughter cells
  • daughter cells formed during mitosis have identical copies of genes while cells
    formed during meiosis are not genetically identical

Biological Molecules:

  • biological molecules are often polymers and are based on a small number of
    chemical elements
  • in living organisms nucleic acids (DNA and RNA), carbohydrates, proteins, lipids,
    inorganic ions and water all have important roles and functions related to their
    properties
  • the sequence of bases in the DNA molecule determines the structure of proteins,
    including enzymes
  • enzymes catalyse the reactions that determine structures and functions from
    cellular to whole-organism level
  • enzymes are proteins with a mechanism of action and other properties determined
    by their tertiary structure
  • enzymes catalyse a wide range of intracellular reactions as well as extracellular
    ones
  • ATP provides the immediate source of energy for biological processes

Ecosystems:

  • ecosystems range in size from the very large to the very small
  • biomass transfers through ecosystems and the efficiency of transfer through
    different trophic levels can be measured
  • microorganisms play a key role in recycling chemical elements
  • ecosystems are dynamic systems, usually moving from colonisation to
    climax communities in a process known as succession
  • the dynamic equilibrium of populations is affected by a range of factors
  • humans are part of the ecological balance and their activities affect it both
    directly and indirectly
  • effective management of the conflict between human needs and conservation
    help to maintain sustainability of resources

Control Systems:

  • homeostasis is the maintenance of a constant internal environment
  • negative feedback helps maintain an optimal internal state in the context of a
    dynamic equilibrium. Positive feedback also occurs
  • stimuli, both internal and external, are detected leading to responses
  • the genome is regulated by a number of factors
  • coordination may be chemical or electrical in nature

Genetic and evolution:

  • molecular kinetic theory:
  • transfer of genetic information from one generation to the next can ensure
    continuity of species or lead to variation within a species and possible
    formation of new species
  • reproductive isolation can lead to accumulation of different genetic
    information in populations potentially leading to formation of new species
  • sequencing projects have read the genomes of organisms ranging from
    microbes and plants to humans. This allows the sequences of the proteins
    that derive from the genetic code to be predicted
  • gene technologies allow study and alteration of gene function in order to
    better understand organism function and to design new industrial and
    medical processes

Energy for Biological Processes:

  • in cellular respiration, glycolysis takes place in the cytoplasm and the
    remaining steps in the mitochondria
  • ATP synthesis is associated with the electron transfer chain in the
    membranes of mitochondria and chloroplasts.
  • in photosynthesis energy is transferred to ATP in the light- dependent stage and the ATP is utilised during synthesis in the light-independent stage.
