This document outlines the topics to be covered in a unit on biology. Part 1 discusses cells at a basic level, including microscopes, differences between cell types, cellular structures, and transport. Part 2 delves deeper into cells, exploring membrane functions, enzymes, mitosis, and the cell cycle. Part 3 focuses on plants, covering photosynthesis, respiration, plant structures, and gas exchange. Part 4 examines body systems such as teeth, digestion, circulation, respiration, and excretion. Part 5 concludes with reproduction, including asexual, sexual, and comparative reproductive processes in various organisms.

1. Unit 1 Revision

2. Part 1 – Cells (the basics) Microscopes (operation & magnification) Differences between eukaryotic and prokaryotic cells Differences between plant and animal cells Cellular organelles – structure and function Importance of surface area to volume ratio Organic substances

3. Part 2 – Cells (advanced) Membrane function – passive transport (diffusion, facilitated diffusion, osmosis), active transport, bulk transport Structure & function of enzymes Mitosis The cell cycle

4. Part 3 - Plants Photosynthesis Cellular respiration (including transpiration) Plant structure (leaves, stems and roots) Plant transport (xylem and phloem) Gaseous exchange (stomata, lenticels, root hairs)

5. Part 4 – Body systems Teeth (and comparative) Digestion (and comparative) Heart, blood and circulation (and comparative) Respiratory system (and comparative) Renal system (and comparative)

6. Part 5 - Reproduction Asexual reproduction Specific knowledge of binary & multiple fission Sexual reproduction (plants, fish, humans) Comparative advantages of asexual and sexual reproduction Meiosis
