• The nucleus is enclosed in a nuclear membrane which has pores to allow RNA and proteins. The nucleus functions the activity in a plant cell and stores the plant’s DNA. (Plant Cell Anatomy, n.d.)
• Inside the nucleus is the nucleolus which produces ribosomes. The ribosomes then transport out of the nucleolus and to the rough endoplasmic reticulum for a process called protein synthesis. (Plant Cell Anatomy, n.d.)
• The rough endoplasmic reticulum is an organelle that plays a large role in synthesising and proteins. This is an important process called protein synthesis. (Plant Cell Anatomy, n.d.)
• The smooth endoplasmic reticulum is responsible for production and packaging of lipids and steroids. (Plant Cell Anatomy, n.d.)
• Ribosomes are rich in

Nutrients that are obtained from the soil from plant roots are nitrogen, Phosphorus, Potassium, Sulfur, Magnesium, Calcium, Iron, Boron, Manganese, Zinc, Molybdenum, Copper. These twelve elements that are obtained from the soil are called mineral nutrients which are then split into more groups; primary, intermediate and micronutrients (Essential Nutrients, n.d.). Primary nutrients are called by its name because they needed and are found in the most amounts. Primary nutrients include nitrogen, phosphorous and potassium. The intermediate nutrients are sulfur, magnesium and calcium which are found less in soil than primary nutrients. Primary and secondary nutrients are called macronutrients. Iron, boron, manganese, zinc, molybdenum and copper are called micronutrients because they are needed in very small amounts. So small in fact that they are needed in parts per million, where 10000 parts per million is 1% of the plants intake (Essential Nutrients, n.d.). This doesn’t mean that the plant won’t grow as well without it though, these nutrients can still be essential to maximum growth spurt (Essential Nutrients,
