__FOur main hormones are responsible for regulating the menstrual cycle. FSH and LH make the ova develop. Oestrogen repairs the lining of the uterus and when this hormone reaches its highest level it causes ovulation. Progesterone continues to repair and maintain the lining of the uterus. If fertilisation and implantation occurs progesterone levels will remain high until the baby is born.__

__Progesterone and oestrogen are mainly produced by the ovary. LH and FSH are produced by the pituitary gland just under the brain__

__**Plant reproduction**__ __Know the parts of the flower__

__**Pollination** is when the pollen lands on the sticky stigma and then starts to gro down the style. The pollen tube grows toward the ovule and when it reaches the ovule the male gamete leaves the pollen tube and fertilises the egg inside the ovule. Eventually the ovule will become a seed while th eovary will become a fruit. Common examples are the apple, oranges__







//**Asexual reproduction**__// Plants can create a baby without using male and female gametes. They can do this by making an exact copy of themselves. The techniques used are; 1. Cuttings - like the process we used when we made our succulent pots. 2. Layering- this is when a branch touches the ground and starts to grow new roots at that point. It can later be cut off the parent plant. It will have its own leaves and roots. 3. Runners - this is like grass growing in a long rope. Every few centimetres there is a tuft of roots and leaves. 4. budding or fission- in budding a baby grows off the side of the parent. In fission the parent splits in 2 to make 2 babies.

This requires the genetic material from 2 organisms to be combined to make a baby organism. Sexual reproduction occurs in humans, mammals, fish, birds, insects, worms and snails as well as most plants. Some plants and some less complex animals can do both asexual reproduction and sexual reproduction. In sexual reproduction the baby has genetic material from both the mother and father and so has characterisitcs from both parents. This is useful in evolution.
