- Control in Humans and Plants
- Menstrual cycle (28 days)
- Hormones involved (Fall Out Lady) FOL. FSH, Oestrogen, LH
- FSH- matures the egg, stimulates production of Oestrogen
- Secreted from the pituitary gland
- Oestrogen- thickens the lining of the womb, inhibits(stops) the production of FSH, stimulates production of LH
- FSH- matures the egg, stimulates production of Oestrogen
- Secreted from the pituitary gland
- Secreted from the ovaries
- FSH- matures the egg, stimulates production of Oestrogen
- LH- releases the egg
- Oestrogen- thickens the lining of the womb, inhibits(stops) the production of FSH, stimulates production of LH
- Secreted from the ovaries
- Secreted from the pituitary gland
- Oestrogen- thickens the lining of the womb, inhibits(stops) the production of FSH, stimulates production of LH
- FSH- matures the egg, stimulates production of Oestrogen
- Hormones involved (Fall Out Lady) FOL. FSH, Oestrogen, LH
- Oral Contraceptives (stops pregnancy)
- First types of contraceptive contained high doses of Oestrogen- egg could not mature
- Caused significant side effects
- Oral contraceptives may contain oestrogen and progesterone to inhibit egg maturation
- birth-control pills now contain a much lower dose
of oestrogen, or are progesterone only
- progesterone-only pills lead to fewer side effects
- First types of contraceptive contained high doses of Oestrogen- egg could not mature
- IVF
- Women given fertility drug containing FSH and LH- stimulated mature egg to be released
- The eggs are collected from the mother and
fertilised by sperm from the father.
- The fertilised eggs develop into embryos. At the stage when they are tiny balls of cells, one or two embryos are inserted into the mother’s uterus
- The eggs are collected from the mother and
fertilised by sperm from the father.
- Women given fertility drug containing FSH and LH- stimulated mature egg to be released
- In shoots auxin increases growth. In roots auxin slows down growth
- Uses of plant hormones in agriculture
- Weed killers contain many auxins which encourage growth. The growth is too rapid and the weeds die
- Rooting hormones encourage plant cutting to grow roots. sSo you can grow an identical plant from a cutting
- Menstrual cycle (28 days)
