Multi-cellular
Organisms
Cells, tissues and organs
Learning Intentions
I can explain what is meant by the term ‘specialisation of cells in animals and plants’.
I can give details of how the structure of an animal cell or plant cell can relate to its function.
I can state that the cells in organs are specialised for a specific function.
I can describe the levels of organisation found in animals and plants.
Stem Cells and Meristems
Learning Intentions
I can state that stem cells have the ability to divide to produce cells that can become different types of cells.
I can state that stem cells are involved in growth and repair.
I can describe the role of meristems in plants.
I can state that non-specialised cells can become any type of plants cell and they contribute to growth.
Control and Communication
Learning Intentions
I can describe the structure of the brain.
I can give details of the functions of the different structures of the brain.
I can describe the structure and function of the central nervous system (CNS).
I can state that the CNS is the communication system.
I can describe the role of sensory and motor neurons.
I can explain the role of sensory, relay and motor neurons in a reflex arc.
I can state that electrical impulses move along neurons.
I can explain the importance of synapses in the nervous system.
I can describe the different responses brought about by the CNS.
I can explain what a reflex action is and give some examples.
I can explain the importance of reflex actions.
I can state the function of endocrine glands.
I can describe the role of hormones in signalling.
I can describe the role of the liver, pancreas, insulin and glucagons in controlling blood glucose levels.
I can state that glucose can be stored as glycogen in the liver.
I can describe the causes and treatment of type 1 and type 2 diabetes.
I can explain the importance of controlling blood glucose levels.
Reproduction
Learning Intentions
I can describe the chromosome complement of gametes.
I can describe the structure if the male and female sex cells and state where they are produced.
I can give details of the male and female reproductive structures, including their function.
I can describe the process of fertilisation in animals.
I can give details of the chromosome complement of a gamete and zygotes in animals.
I can name the sex cells found in plants and state where they are produced.
I can describe the reproductive structures found in plants and give their functions.
I can describe the process of fertilisation in plants.
I can give details of the chromosome complement of a gamete and zygotes in plants.
