This powerpoint is purposefully made for iGCSE Biology students using the most recent Cambridge syllabus.

It covers the following criteria - 2.1 Cell structure

Core

1. Describe and compare the structure of a plant cell with an animal cell, limited to: cell wall, cell membrane, nucleus, cytoplasm, chloroplasts,
   ribosomes, mitochondria, vacuoles

2. Describe the structure of a bacterial cell, limited to: cell wall, cell membrane, cytoplasm, ribosomes, circular DNA, plasmids

3. Identify the cell structures listed in 2.1.1 and 2.1.2 in diagrams and images of plant, animal and bacterial cells

4. Describe the functions of the structures listed in 2.1.1 and 2.1.2 in plant, animal and bacterial cells

5. State that new cells are produced by division of existing cells

6. State that specialised cells have specific functions, limited to:
   (a) ciliated cells – movement of mucus in the trachea and bronchi
   (b) root hair cells – absorption
   © palisade mesophyll cells – photosynthesis
   (d) neurones – conduction of electrical impulses
   (e) red blood cells – transport of oxygen
   (f) sperm and egg cells (gametes) – reproduction

7. Describe the meaning of the terms: cell, tissue, organ, organ system and organism as illustrated by examples given in the syllabus
