1 Cell Biology
1.1 Cell Structure
1.1.1 Cell Type
1.1.1.1 Fungal

Annotations:

  • Fungal Cells contain, Cell Wall, Cell Membrane, Nucleus, Ribosome, Cytoplasm, Mitochrondia, Vacuole
1.1.1.2 Bacterial

Annotations:

  • Bacterail Cells contain, Cell Wall, Cell Membrane, Ribosome, Cytoplasm, Plasmid
1.1.1.3 Plant

Annotations:

  • Plant Cells contain Cell Wall, Cell Membrane, Ribosome, Cytoplasm, Nucleus, Chloroplasts, Vacuole, Mitochondria
1.1.1.4 Animal

Annotations:

  • Animal Cells contain Cell Membrane, Cytoplasm, Nucleus, Ribosome, Mitochondria
1.1.2 Organelles ect
1.1.2.1 Nucleus

Annotations:

  • The Nucleus contains all the genetic material in the cell, and controls cell activities. It is found in Animal, Plant and Fungal Cells.
1.1.2.2 Plasmid

Annotations:

  • A plasmid is a small ring of genetic material which is only found in bacterial cells.
1.1.2.3 Cell membrane

Annotations:

  • A cell membrane, is a selectiveley permeable layer which controls entry and exit of substances such as O2, CO2, Glucose and waste products.It is found in Animal, Plant, Fungal and Bacterial Cells.
1.1.2.4 Cytoplasm

Annotations:

  • The cytoplasm is watery, jelly like material in the cell which contains organelles, the cytoplasm is the site for chemical reactions. The Cytoplasm is found in Animal, Plant, Fungal and Bacterial Cells.
1.1.2.5 Cell Wall

Annotations:

  • The cell wall helps protect and support the cell. It is found in Plant, Fungal and Bacterial Cells. 
1.1.2.6 Vacuole

Annotations:

  • The vacuole is a sac which stores a solution of water, salt and sugar it helps support the cell. It is found in Plant and Fungal Cells.
1.1.2.7 Chloroplast

Annotations:

  • The Chloroplasts make carbohydrates in green plant cells using light energy in the process of photosynthesis. Only found in Plant Cells.
1.1.2.8 Mitochondria

Annotations:

  • Mitochondria(mitochondrion) produce ATP in aerobic respiration. Found in Animal, Plant, Fungal Cells.
1.1.2.9 Ribosome

Annotations:

  • Ribosomes are the sites for protein synthesis. Found in Animal, Plant, Fungal, Bacterial
1.2 Transport across cell membranes
1.2.1 Diffusion

Annotations:

  • Diffusion is the passive movement of molecules from a high concentration to a low concentration. They diffuse through the lipid bi-layer.  Glucose and Oxygen enter the cell by diffusion. Carbon Dioxide diffuses out of the cell.
1.2.1.1 Gas Diffuses
1.2.1.2 High to Low Gradient
1.2.1.3 Passive Process
1.2.2 Osmosis

Annotations:

  • Osmosis is the passive movement of water molecules from a high concentration to a low concentration. Water Travels through the channel protein in the selectively permeable membrane. 
1.2.2.1 Hypotonic

Annotations:

  • Animal cells burst, Plant cells become turgid. Hypotonic means that the solution contain the higher concentration of water
1.2.2.2 Isotonic

Annotations:

  • Nothing should happen. Isotonic means that the cell contains the same concentration as the solution
1.2.2.3 Hypertonic

Annotations:

  • Both animal and plant cells will become plasmolysed.  Hypertonic means the solution contains the lower concentration. 
1.2.2.4 Water travels by osmosis
1.2.2.5 High to Low Gradient
1.2.3 Active Transport

Annotations:

  • Active transport is the movement of molecules from a region of low concentration to a higher concentration. This can be carried out using carrier proteins.
1.2.3.1 Requires Energy
1.2.3.2 Low to High Gradient
1.2.3.3 Carrier Protein
1.2.3.4 Endo/Exocytosis
1.3 Producing new cells
1.3.1 Chromosomes

Annotations:

  • In the nucleus of most cells there is two matching sets of chromosomes, each set has been copied from the parents cell.
1.3.2 Haploid & Diploid

Annotations:

  • Haploid, (n) has 23 chromosomes,  Diploid (2n) has 46 chromosomes.
1.3.3 Mitosis
1.4 DNA & Production of proteins
1.5 Proteins and enzymes
1.6 Genetic Engineering
1.7 Photosynthesis
1.8 Respiration
