13 THE MEMBRANES OF DIFFERENT TYPES OF CELLS ARE INVOLVED IN MANY DIFFERENT FUNCTIONS – 25 MARKS Membranes are found in all organisms‚ around and within cells. They control the movements in and out of cells‚ as well as protecting cells. They also allow different functions to occur. They have the same basic structure called the plasma membrane. All plasma membranes‚ around or inside cells have a same phospholipid bilayer structure. Phospholipids contribute to the flexibility of membranes and transfer

Organic farming provides not only an alternative safe and healthy farming model‚ but a way to correct the flaws in our current system. There are many benefits of organic foods and organic farming. Organic foods are free of harmful chemicals‚ artificial flavors‚ and preservatives. Conventional farmers use over 300 different pesticides to grow non-organic foods.

Organic farming cannot feed the developing world It is argued that without pesticides and genetically modified crops‚ farming is not economically viable in the developing world. Non-organic farming allows you to farm land that would otherwise not be farmable. Yields are high and costs are low. However‚ there is a worry that intensive farming in these countries will destroy the fertility of the land and in the long run organic farming will secure the future for sustainable farming.
