CHAPTER 7 LECTURE SLIDES Respiration • Organisms can be classified based on how they obtain energy: • Autotrophs – Able to produce their own organic molecules through photosynthesis • Heterotrophs – Live on organic compounds produced by other organisms • All organisms use cellular respiration to extract energy from organic molecules Cellular respiration • Digestion – enzymes breaking down large macromolecules into smaller ones. • Cellular respiration is a series of reactions

PAPER 3 Answer all question. Question 1 Transpiration is the evaporation of water vapour from the leaves surface. Air movement is one of the factor that affects the evaporation of water vapour. A group of student carried out an experiment to study the effect of air movement on rate of transpiration of plants. Diagram 1 shows the apparatus used by the students. The experiment was conducted under still air and strong fan speed. Diagram 1 The time taken for the air bubble in the capillary tube to

VITAMIN A - (retinyl palmitate‚ beta-carotene‚ lutein‚ lycopene‚ mixed carotenoids) POTENTIAL BENEFITS: Helps support bone formation and cell membranes. It’s important to support the eyes‚ hair‚ skin and teeth. In other words‚ Vitamin A stimulates growth and vitality. It helps form the colour purple which is essential for night vision. It’s great for immune system functions - like fighting infection‚ colds‚ flu and bacteria. It also helps maintain the healthy function of the reproductive organs

The phrase MRS GREN is a way to remember them M Movement All living things move‚ even plants R Respiration Getting energy from food S Sensitivity Detecting changes in the surroundings G Growth All living things grow R Reproduction Making more living things of the same type E Excretion Getting rid of waste N Nutrition Taking in and using food

If lack of I2‚ the gland cant release thyroxin and will swell forming a ‘goiter’

She brings the head back to

Movement Most organisms are able to move their whole body even plants can shift their stem towards the sunlight and their roots move towards healthy soil. 2. Respiration IT is the breakdown of food inside a living organism IT IS VITAL for survival. 2 types Aerobic Respiration which involves O2 & glucose breaking down to form CO2 water & ENERGY. Anaerobic Respiration which is the incomplete breakdown
