AQA A Level Biology Specification Reference: - 3.3.2 Gas exchange  in the tracheal system of an insect (tracheae, tracheoles and spiracles).

 

CIE A Level Biology Specification Reference: - N/A

 

Edexcel A Level Biology (Biology A – Salters-Nuffield) Specification Reference: - None Specific but useful for: Know the properties of gas exchange surfaces in living organisms (large surface area to volume ratio, thickness of surface, difference in concentration).

 

Edexcel A Level Biology (Biology B) Specification Reference: - Topic 4: Exchange and Transport: 4.3 Gas exchange: i Understand how insects are adapted for gas exchange. 7: Dissect an insect to show the structure of the gas exchange system.

 

OCR A Level Biology (Biology A) Specification Reference: - Module 3: Exchange and transport: In this module, learners study the structure and function of gas exchange and transport systems in a range of animals and in terrestrial plants.  Ventilation and gas exchange systems in mammals, bony fish and insects are used as examples of the properties and functions of exchange surfaces in animals. To include: insects – spiracles, trachea, thoracic and abdominal movement to change body volume, exchange with tracheal fluid.

OCR A Level Biology (Biology B) Specification Reference: -N/A

 

WJEC A Level Biology Specification Reference: -Component 3: REQUIREMENTS FOR LIFE: (d) the common features of the specialised respiratory surfaces of larger animals and the adaptation of respiratory surfaces to environmental conditions - the adaptations of the insect tracheal system to life in a terrestrial environment.

AQA A Level Biology Specification Reference: -3.3.2 Gas exchange by the leaves of dicotyledonous plants (mesophyll and stomata). Students could use an optical microscope to examine vertical sections through a dicotyledonous leaf.

 

CIE A Level Biology Specification Reference: - 7.1 Structure of transport tissues: draw and label from prepared slides plan diagrams of transverse sections of stems, roots and leaves of herbaceous dicotyledonous plants using an eyepiece graticule to show tissues in correct proportions. Draw and label from prepared slides the cells in the different tissues in roots, stems and leaves of herbaceous dicotyledonous plants using transverse and longitudinal sections.

 

Edexcel A Level Biology (Biology A – Salters-Nuffield) Specification Reference: - None Specific but useful for:  4.7 Know the ultrastructure of plant cells (cell walls, chloroplasts, amyloplasts, vacuole, tonoplast, plasmodesmata, pits and middle lamella) and be able to compare it with animal cells.

 

Edexcel A Level Biology (Biology B) Specification Reference: - Topic 4: Exchange and Transport: 4.3 Gas exchange: Understand gas exchange in flowering plants, including the role of stomata, gas

exchange surfaces in the leaf and lenticels.

 

OCR A Level Biology (Biology A) Specification Reference: - Module 3: Exchange and transport: In this module, learners study the structure and function of gas exchange and transport systems in a range of animals and in terrestrial plants.  3.1.3 Transport in plants: (b) (i) the structure and function of the vascular system in the leaves of herbaceous dicotyledonous plants.

OCR A Level Biology (Biology B) Specification Reference: -2.2.4 Transport systems in plants: the structure & function of leaves. To include xylem vessels, sieve tube elements and companion cells in the roots, stems and leaves of monocotyledonous crop plants (cereals) and dicotyledonous crop plants (broad-leaved crops e.g. carrots, potatoes). 

 

WJEC A Level Biology Specification Reference: - Requirements for Life: 1. Adaptations for gas exchange. The role of the leaf as an organ of gas exchange, including stomatal opening and closing. SPECIFIED PRACTICAL WORK. Scientific drawing of a low power plan of a prepared slide of T.S. dicotyledon leaf e.g. Ligustrum (privet), including calculation of actual size and magnification of drawing.

CIE A Level Biology Specification Reference: - N/A

 

Edexcel A Level Biology (Biology A – Salters-Nuffield) Specification Reference: - None Specific but useful for 1.1 Understand why many animals have a heart and circulation (mass transport to overcome limitations of diffusion in meeting the requirements of organisms). 2.1 i) Know the properties of gas exchange surfaces in living organisms (large surface area to volume ratio, thickness of surface, difference in concentration).

 

Edexcel A Level Biology (Biology B) Specification Reference: - Topic 4: Exchange and Transport: ii Understand why organisms need a mass transport system and specialised gas exchange surfaces as they increase in size. 4.3 Gas exchange: Understand how fish are adapted for gas exchange.

Module 3: Exchange and transport: In this module, learners study the structure and

function of gas exchange and transport systems in a range of animals and in terrestrial plants. Ventilation and gas exchange systems in mammals, bony fish and insects are used as examples of the properties and functions of exchange surfaces in animals. Learners should be able to demonstrate and apply their knowledge and understanding of: (f) the mechanisms of ventilation and gas exchange in bony fish bony fish – changes in volume of the buccal cavity and the functions of the operculum, gill filaments and gill lamellae (gill plates); countercurrent flow.
