Here are the answers to the questions: Step 1: Answer question 9.1. 9.1: (a) Open stomata: The numbers indicating open stomata and thus high rates of transpiration during the day are 1 and 4. (b) Closed stomata: The numbers indicating closed stomata and thus very low rates of transpiration during the night are 2 and 3. Step 2: Answer question 9.2. 9.2: (a) One environmental condition responsible for the change at 4 (high transpiration during the day) is light intensity (or presence of light). (b) One environmental condition responsible for the change at 2 (low transpiration during the night) is the absence of light (or darkness). Step 3: Answer question 10.1. 10.1: A: Epidermis B: Cortex C: Endodermis D: Vascular cylinder (or Stele) Step 4: Answer question 10.2. 10.2: Part D (vascular cylinder) contains xylem and phloem for transport. Xylem adaptations: It consists of hollow, continuous tubes (vessels and tracheids) to allow for efficient, uninterrupted flow of water. Its walls are lignified (thickened with lignin) to provide structural support and prevent the vessels from collapsing under tension. Phloem adaptations: It consists of sieve tubes with perforated sieve plates, allowing for the efficient transport of sugars. Companion cells are associated with sieve tube elements, providing metabolic support for the active transport of sugars. Step 5: Answer question 10.3. 10.3: The collective name of the tissues that transport water and food in the structure shown above is vascular tissues.
