nutrients lacking in one or more key nutrients Effects of malnutrition 1. Obesity - Too much food (carbohydrate‚ fat or protein) 2. Coronary heart disease Too much saturated/animal fat in the diet results in high cholesterol levels. Cholesterol can stick to the walls of arteries‚ gradually blocking them. If coronary arteries become blocked‚ the results can be angina and coronary heart disease. 3. Starvation Too little food can result in starvation. Extreme

Planning Introduction Stomata are pores on the bottom of leaves of vascular plants. The function of stomata is to allow gaseous exchange (transpiration) between the plant and the external environment (see diagrams below). This process is carried out by the plant‚ which controls the opening and closing of stomata via the guard cells. The more stomata a leaf contains the greater the rate of gas exchange and the less water it will be able to accumulate. Stomatal pores are formed between
