Molecules Of Life

Cell Structure:

Animal Cells Contain a....

  • Nucleus which controls the cells activities.
  • Cell Membrane which holds the cell together and controls what goes in and out of the cells.
  • Cytoplasm where most of the cells reactions take place.
  • Mitochondria where most of the reactions involved in respiration take place.
  • Ribosomes where proteins are synthesised.

Plants Cell's Contain all the structures of an animal cell but also contain ....

  • Chloroplasts where photosynthesis takes place.
  • Cell Wall which contains cellulose which strengthens the cell. (Supports it).
  • Vacuole filled with cell sap to support the cell.

DNA

The Nucleus contains genes. Each Gene:

  • Is a section of a Chromosome made of DNA.
  • Codes for a particular protein.

DNA is made of 2 strands coiled to form a double helix, each strand containing chemicals called bases. There are 4 different types of bases, with cross-links between the strands formed by pairs of bases. Each
