Science Double Award - 4SD0 PearsonEdexcel

Variety Of Living Organisms

Muhtasari

Life on Earth ranges from microscopic bacteria that thrive in boiling hot springs to giant redwood trees that stand for thousands of years. Biologists organise this staggering diversity into groups based on shared features, splitting organisms into eukaryotes and prokaryotes and then asking which ones cause disease.

In this lesson you will compare the four eukaryotic kingdoms (animals, plants, fungi and protoctists), explore how prokaryotic bacteria differ from them, and learn what makes an organism a pathogen. These distinctions appear throughout the biology section of the Double Award and form the foundation for topics on cells, disease and ecology.

Malengo

  1. Describe the common features shown by eukaryotic organisms: plants, animals, fungi and protoctists
  2. Describe the common features shown by prokaryotic organisms such as bacteria
  3. Understand the term pathogen and know that pathogens may include fungi, bacteria, protoctists and viruses

Maelezo ya Somo

Walk through a forest and you will pass animals, plants, fungi growing on dead logs, and invisible protoctists in every puddle. All of them are built from eukaryotic cells with a membrane-bound nucleus. Meanwhile, bacteria in the soil beneath your feet belong to an entirely different cell plan: prokaryotic, smaller, and lacking a true nucleus. Sorting life into these groups is not just an academic exercise; it determines how we diagnose disease, develop antibiotics, and protect crops.
