What are the functions and adaptations of epidermal cells, stomatal pores, guard cells, xylem vessels, and broad, thin leaves in plants, and what are the physiological changes for heat loss in human s

Here are the answers to your questions: Name parts P and R: P: Epidermal cell* R: Stomatal pore* How is Q adapted to its function? Part Q (guard cell) is adapted to its function by having chloroplasts to perform photosynthesis, which helps regulate its turgor. Its inner cell walls are thicker than the outer walls, causing the cells to bow outwards and open the stomatal pore when turgid. They also have a kidney or bean shape to facilitate this opening and closing. For a leaf to be efficient for photosynthesis, it has to be broad and thin. Give about explanation. A broad leaf provides a large surface area to capture maximum sunlight and absorb carbon dioxide. A thin leaf ensures a short diffusion distance for carbon dioxide to reach the photosynthetic cells and for oxygen to exit, and allows light to penetrate all photosynthetic tissues. State 2 structural adaptations that make xylem vessel suitable for transport of water and mineral salts. • Xylem vessels have lignified walls which provide mechanical support and prevent the vessels from collapsing under tension. • They form continuous tubes from the roots to the leaves, with no cross-walls, allowing for an uninterrupted flow of water. State 2 physiological changes that take place in a human skin in order to facilitate heat loss from the body. • Vasodilation: Arterioles supplying blood to the skin surface dilate, increasing blood flow near the surface, allowing more heat to radiate away. • Sweating: Sweat glands secrete sweat onto the skin surface. As sweat evaporates, it takes latent heat from the body, cooling it. State two functions of Sebum and Golgi apparatus. • Sebum: 1. Lubricates the skin and hair, keeping them soft and pliable. 2. Prevents excessive water loss from the skin. • Golgi apparatus: 1. Modifies, sorts, and packages proteins and lipids synthesized in the endoplasmic reticulum for secretion or delivery to other organelles. 2. Involved in the formation of lysosomes and the secretion of substances like mucus. Dental formula I (1)/(1) C (0)/(0) P (3)/(3) M (3)/(3) Suggest the mode of feeding of the animal and give a reason. Mode of feeding: Herbivore* Reason: The absence of canines (C (0)/(0)) indicates it does not tear meat. The presence of well-developed incisors (I (1)/(1)) for cutting vegetation and numerous premolars and molars (P (3)/(3) M (3)/(3)) for grinding plant material are characteristic of herbivores. Name the organelles that would be most likely found in large numbers in a cell that performs the function below: i) A cell in the ileum that actively takes glucose. Mitochondria* (for producing ATP required for active transport). ii) A cell in the liver that breaks down foreign bodies. Lysosomes* (contain digestive enzymes to break down foreign substances).
