EASE 2
Cell membrane and transport
Fluid mosaic membrane
fluid mosaic model of membrane structure with reference to the hydrophobic and
hydrophilic interactions
arrangement of cholesterol, glycolipids and glycoproteins in cell surface membranes
roles of phospholipids, cholesterol, glycolipids, proteins and glycoproteins in cell
surface membranes
Movement into and out cell
processes of simple diffusion, facilitated diffusion, osmosis, active
transport, endocytosis and exocytosis
Investigate simple diffusion and osmosis using plant tissue and non-living materials
the principle that surface area to volume ratios decrease with increasing size
effects of immersing plant tissues in solutions of different water potentials
movement of water between cells and solutions in terms of water potential and different effects of the movement of water on plant cells and animal cells
Mitotic cell cycle
Replication and division of nuclei acid and cell
structure of a chromosome.
importance of mitosis in the production of genetically identical daughter cells
Outline the mitotic cell cycle.
how uncontrolled cell division can result in the formation of a tumour
Chromosome behaviour in mithosis
behaviour of chromosomes in plant and animal cells during the mitotic cell cycle
Interpret photomicrographs, diagrams and microscope slides of cells in different stages of the mitotic
cell cycle
Nucleic acid and protein synthesis
Structure of nucleic acid and replication DNA
structure of nucleotides, including the phosphorylated nucleotide ATP
the bases adenine and guanine are purines and that the
bases cytosine, thymine and uracil are pyrimidines
the structure of a DNA molecule as a double helix
the structure of an RNA molecule,
the semi-conservative replication of DNA during the
S phase of the cell cycle
Protein synthesis
a polypeptide is coded for by a gene and that a gene is a sequence of nucleotides that
forms part of a DNA molecule.
e the principle of the universal genetic code
the information in DNA is used during transcription and translation to construct
polypeptides
a gene mutation is a change in the sequence of base pairs in a DNA molecule that may
result in an altered polypeptide
a gene mutation is a result of substitution or deletion or insertion of nucleotides in DNA
and outline how each of these types of mutation may affect the polypeptide produced.
