Key Topics to Revise

1

1. Life Processes and Nutrition

  • Movement alone is not enough to define life because some living things may not show visible movement, while molecular movement continues inside living cells.
  • Living organisms must maintain their structure, repair damage, and support growth. This needs energy and raw materials from outside the body.
  • Nutrition is the process by which food is taken in and used to provide energy and materials for the body.

2. Human Nutrition and Digestion

  • The human alimentary canal is a long tube from mouth to anus.
  • Food is broken into smaller pieces by teeth and mixed with saliva in the mouth.
  • Saliva contains salivary amylase, which breaks starch into simple sugar.

3. Respiration and Energy Release

  • Glucose breakdown begins in the cytoplasm in all organisms.
  • Glucose, a six-carbon molecule, is broken into pyruvate, a three-carbon molecule, in the first step of respiration.
  • Aerobic respiration takes place in the presence of oxygen and releases much more energy than anaerobic respiration.

4. Transportation in Human Beings and Plants

  • Blood transports food, oxygen, carbon dioxide, and wastes in the body.
  • Blood has plasma and suspended cells.
  • Plasma carries food, carbon dioxide, and nitrogenous wastes in dissolved form.
