Designed for the new specification AQA GCSE course but can be modified for other exam boards. 15 slides covering animal and plant cells. By the end of the powerpoint students would have covered: **4.1.1.2 Animal and plant cells ** Students should be able to explain how the main sub-cellular structures, including the nucleus, cell membranes, mitochondria, chloroplasts in plant cells and plasmids in bacterial cells are related to their functions. Most animal cells have the following parts: -a nucleus -cytoplasm -a cell membrane -mitochondria -ribosomes. In addition to the parts found in animal cells, plant cells often have: -chloroplasts -a permanent vacuole filled with cell sap. Plant and algal cells also have a cell wall made of cellulose, which strengthens the cell. Students should be able to use estimations and explain when they should be used to judge the relative size or area of sub-cellular structures.

Designed for the new specification AQA GCSE( covers spec point 4.5.3.4 ) course but can be modified for other exam boards. 23 slides covering Hormones in human reproduction: By the end of the powerpoint students would have covered: 4.5.3.4 Hormones in human reproduction Students should be able to describe the roles of hormones in human reproduction, including the menstrual cycle. During puberty reproductive hormones cause secondary sex characteristics to develop. Oestrogen is the main female reproductive hormone produced in the ovary. At puberty eggs begin to mature and one is released approximately every 28 days. This is called ovulation. Testosterone is the main male reproductive hormone produced by the testes and it stimulates sperm production. Several hormones are involved in the menstrual cycle of a woman. Follicle stimulating hormone (FSH) causes maturation of an egg in the ovary. Luteinising hormone (LH) stimulates the release of the egg. Oestrogen and progesterone are involved in maintaining the uterus lining. (HT only) Students should be able to explain the interactions of FSH, oestrogen, LH and progesterone, in the control of the menstrual cycle. (HT only) Students should be able to extract and interpret data from graphs showing hormone levels during the menstrual cycle. Contains examination questions Alternative starter question for triple or combined science students.
