Human and Plant hormones

HideShow resource information
What is a Hormone
Chemicals that are released by the glands such as the ovaries.
1 of 16
Name the hormones for ovary, pancreas and the pituitary gland
estrogen, insulin and FSH (follicle stimulating hormone)
2 of 16
What gland involves FSH and explain its functions
it's secreted by the pituitary gland. causes the egg to mature in an ovary and stimulates to release the hormone estrogen
3 of 16
What gland involves estrogen and explain the functions
secreted by the ovaries. stops FSH being produced therefore only 1 egg matures in the cycle. stimulates the pituitary gland to release LH
4 of 16
What does LH do in the hormone?
causes the matured egg to be released from the ovary. at day 14 it's released (the matured egg)
5 of 16
What are Oral contraceptives
contains hormones to inhibit the production of FSH- no eggs mature
6 of 16
What does IVF stand for
In vitro fertilisation
7 of 16
Step 1 of IVF
1. Mother receives FSH and LH- causes several eggs to mature.
8 of 16
Step 2 (IVF)
Eggs are collected and mixed with the sperm from the father
9 of 16
Step 3 (IVF)
Fertilised eggs are allowed to develop into embryos then implanted into the mothers womb as they can continue growing into full developed babies
10 of 16
What the pros of IVF
allows people with fertility problems to have children
11 of 16
What is the cons of IVF
expensive and potentially low success rate and could lead mothers becoming pregnant several babies> low birth weight
12 of 16
What does auxin control
phototropism (light) and geotropism (gravity)
13 of 16
When the tip of the shoot is covered what happens?
it doesn't grow towards light as they are sensitive to it
14 of 16
Light causes the auxin to do what?
concentrate on the darker side- spreads down (shoot) and causes cells on that side to grow faster
15 of 16
what does gravity do to the auxin?
gravity makes the auxin concentrate on the lower side. inhibits cell growth as the lower side grows slower than the top
