What does it mean when a plant is specialised
Transpiration
=loss of water by evaporating from the leaves . Moment of water the iota to the leaves is called the transpiration stream
Stomata
What is transpiration
What is stomata
Translocation
=is the transport of solicitors and other nutrients around a plant
Phloem
What is translocation
What is phloem
Water uptake in plants
Environmental factors=change the rate of water uptake in plants
Factors any affect transpiration
Factor and effect on transpiration
Light intensity=
Air movement=
Temperature=
Using a Potometer
What is water uptake in plants
What is an environmental factor Describe it What is transpiration What factors affect transpiration What is Potometer How can you measure the rate of transpiration Describe this
How the rate of transpiration be measured (calcaluted)
Hormones and nerves
Hormones
Hormones =chemical messengers that target organs in the body
Product and transport
Hormones=
Target Organs=where hormone acts
Release of hormones
Hormone / target organ(s)
ADH -Kidney
FSH/LH-ovaries
Insulin and glucagon-liver/muscle/adipose tissue
Adrenalin-various organs e.g, heart , liver , skin
Progesterone -uterus
Oestrogen -ovaries , uterus , pituitary Gland
Testosterone -male reproductive organs
What is a hormone What is production and transport Describe how hormones are produced What is target organ Describe it Describe different hormones Describe hormones and nerves Describe the release of hormones Describe a hormone and it's target organ/target organs
Menstrual cycle
What is the menstrual cycle
How long does it last
What is contraception
Blood glucose regulation
Homeostasis
Pancreatic control
What is blood glucose regulation What is homeostasis Describe it What is pancreatic control Describe it
Diabetes
What is diabetes What is the cause of type 1 diabetes What is the control of type 1 diabetes What is the controls of type 2 diabetes What is the cause of type 2 diabetes What is type 1 diabetes What is type 2 diabetes How do yo calculate body mass index(BMI)
Exchange materials
substance
What needs to be transported How are substances exchanged Describe more complex organisms Describe substance/site exchange/reason for exchange What is adaptions for exchange
Alveoli
Alveoli is adapted for gas exchange by diffusion between air in the lungs and blood in capillaries
The lungs
=part of the breathing system .the breathing system takes air into and out of the body .in the lungs:
-oxygen diffuses from the air into the blood
-carbon dioxide diffuses from the blood into the air
Lounges are adapted for efficient gas exchange
What is alveoli What is adapted for What are the lungs part of Describe the Describe how the lungs are adapted for efficient gas exchange
Blood
Made of four main parts:plasma , red blood cells ,white blood cells and platelets
Each part of the blood has a particular function(job)
Blood plasma
Plasma is the liquid part of blood:
-carries the blood through the blood vessels
-contains many dissolved substance , such as carbon dioxide and glucose
White blood cells
Platelets
What is boos made of What does each part have What is blood plasma /plasma Describe its functions What are white cells Describe their function What is a platelets Describe their function
Blood vessels
Types of blood arteries
What are the 3 types of blood vessels
The heart
What is the function I’d the heart
Describe the structure of the heart
What is blood circulation describe it and
Aerobic respiration

Describe the use of energy from respiration in animals
Describe it in plants and animals
Anaerobic respiration
What is anaerobic respiration
How does it work
Describe how it works in plants and fungal cells
Describe the differences between aerobic and anaerobic respiration
Rate of respiration practical
Safety and living Organisms
Factor affecting respiration
Calculating rate of respiration:
Rate=change
