Identify the plant tissues described and explain their adaptations and functions, including differences between vascular tissues and interpretation of growth data.

Step 1: Identify tissues and their adaptations. a) Tissue B is epidermal tissue. Tissue C is parenchyma tissue. b) Two structural adaptations of tissue A (stoma) for its functions are: • The guard cells are bean-shaped and can change turgor pressure to open and close the stomatal pore, regulating gas exchange and transpiration. • Guard cells contain chloroplasts, allowing them to photosynthesize and produce ATP, which is used to actively transport ions, leading to water movement and turgor changes. Step 2: Explain tissue suitability and differences between vascular tissues. a) Tissue C (parenchyma) would not be suitable as the main tissue in the root between the epidermis and the xylem because it is not specialized for the efficient long-distance transport of water and minerals, which is a primary function of the root's vascular tissue (xylem). b) Two differences between xylem vessels and phloem sieve tubes are: • Xylem vessels transport water and minerals, while phloem sieve tubes transport sugars. • Xylem vessels are composed of dead cells with lignified walls, forming continuous tubes, whereas phloem sieve tubes are living cells with sieve plates and are associated with companion cells. Step 3: Interpret growth graphs. a) From the "Average growth of width of stem over time" graph, the plant's stem was 4 cm wide after 3 years. b) From the "Average growth of length of stem over time" graph, at 3 years, the stem was 18 cm long. Step 4: Identify growth conditions, constant factors, and reliability measures. a) Two environmental conditions that could have favoured fast growth between 2 and 4 years are optimal temperature and sufficient water. b) One factor the scientists kept constant in this investigation is the species of plant. c) One way in which the reliability of the investigation was ensured is by using a large sample size. Step 5: Identify parts of the epidermal tissue and explain its function. a) Identification of parts in the diagram: • X: Guard cell • Y: Stomatal pore • Z: Epidermal cell b) Three processes occurring at Z (epidermal cell) are cellular respiration, protein synthesis, and osmosis. c) One way in which the epidermal tissue of a leaf is suited for maximum absorption of light is that the upper epidermal cells are transparent and lack chloroplasts, allowing light to pass through to the palisade mesophyll layer below, where the majority of photosynthesis occurs.
