Relevant chapter: B1 Cell structure and transport. AQA Biology third edition textbook-Page 14-15
Specification requires students to know the following;
Substances may move into and out of cells across the cell membranes
via diffusion.
Diffusion is the spreading out of the particles of any substance in solution, or particles of a gas, resulting in a net movement from an area of higher concentration to an area of lower concentration.
Some of the substances transported in and out of cells by diffusion are oxygen and carbon dioxide in gas exchange, and of the waste product urea from cells into the blood plasma for excretion in the kidney.
Students should be able to explain how different factors affect the rate
of diffusion.
Factors which affect the rate of diffusion are:
•• the difference in concentrations (concentration gradient)
•• the temperature
•• the surface area of the membrane.
I have designed a mitosis and meiosis revision exam question pack, total marks /20. Contains a range of short and longer answer questions also requires students to interpret diagrams. This is a great piece of homework or mini class test, that can allow you to determine whether your students can distinguish between these two processes. I've attached the mark scheme separately as it's a great self/peer-assessed activity (reduce the marking load).
Food tests (RP 4-separate science). This practical was completed in one lesson, students were asked to construct a graph from their data for homework.
How did i deliver this practical?
Groups of 3, each group needs a test tube rack, 3 x test tubes and 1 x boiling tube. Goggles must be worn throughout the practical.
Circus activity-students visited a station to complete a food test (avoids too many students doing the same test or taking all the reagents).
Instead of using a hot water bath for the simple sugars test i lit a bunsen burner and allowed students to heat their solution in a boiling tube, holding it at a slant near the flame using tongs. Students really enjoyed this and the colour change is very sudden. Only one bunsen burner needs to be on for this and can be manned by the teacher to prevent misuse.

Blood glucose concentration is monitored and controlled by the pancreas.
If the blood glucose concentration is too high, the pancreas produces the hormone insulin that causes glucose to move from the blood into the cells. In liver and muscle cells excess glucose is converted to glycogen for storage. Students should be able to explain how insulin controls blood glucose (sugar) levels in the body.

In Type 2 diabetes the body cells no longer respond to insulin produced by the pancreas. Students should be able to compare Type 1 and Type 2 diabetes and explain how they can be treated.
Students should be able to extract information and interpret data from graphs that show the effect of insulin in blood glucose levels in both people with diabetes and people without diabetes. (Will be incorporated in treating diabetes lesson).
Higher content- If the blood glucose concentration is too low, the pancreas produces the hormone glucagon that causes glycogen to be converted into glucose and released into the blood.

Students are required to know the following
Students should be able to explain how the structures of plant tissues are related to their functions.
Plant tissues include:
• epidermal tissues
• palisade mesophyll
• spongy mesophyll
•xylem and phloem
•meristem tissue found at the growing tips of shoots and roots.
The leaf is a plant organ. Knowledge limited to epidermis, palisade and spongy mesophyll, xylem and phloem, and guard cells surrounding stomata. Students should be able to explain how the structure of root hair cells, xylem and phloem are adapted to their functions.
Root hair cells are adapted for the efficient uptake of water by osmosis, and mineral ions by active transport. Xylem tissue transports water and mineral ions from the roots to the stems and leaves. It is composed of hollow tubes strengthened by lignin adapted for the transport of water in the transpiration stream. The role of stomata and guard cells are to control gas exchange and water loss.
Phloem tissue transports dissolved sugars from the leaves to the rest of the plant for immediate use or storage. The movement of food molecules through phloem tissue is called translocation.
Phloem is composed of tubes of elongated cells. Cell sap can move from one phloem cell to the next through pores in the end walls.
Detailed structure of phloem tissue or the mechanism of transport is not required.
NB: This is a BIOLOGY (SEPARATES) ONLY lesson
