The resource is prepared for teachers and students for revision. It deals with paying attention to features of adaptation that make cells and structures able to perform functions that no other cell or structure can perform. (Adaptation and Function).

The resource offers students the chance to learn and improve on their skills of presenting quantitative and qualitative data in graphical forms. It would make students appreciate when to present data as histograms and when to present as bar charts. The resource should be used after teaching biological variation. Answers have been provided to the questions.

This resource shows photomicrographs of the internal structures of the root and stem of a flowering plant. It shows the distribution of tissues in the root and stem. It could be used to reinforce the teaching and learning of the anatomy of flowering plants as well as evaluate how well the topic has been understood. Answers to the questions are provided

The resource is designed to be used as a worksheet to assess students on how well they have understood the principles behind the experimental set-ups in investigating factors that affect the process of photosynthesis. It will help students to apply knowledge to situations.

The resource is to help students to link the various processes involved in digestion and to appreciate the topic better. Students will understand how pH affects digestion, how specific enzymes act on specific food substances, and so on. Teachers may also use it to assess students' level of understanding of the topic.

This resource shows graphic pictures of plant cells that have been placed in media of different concentrations. The questions that follow could be used both to deepen knowledge and assess students' level of understanding of the topic of osmosis in plant cells.

This resource helps to emphasize the means by which plants reproduce asexually through stem cuttings and leaf cuttings. It provides photographic images of these specimens for students to appreciate and study.

This resource, though concerns anaerobic respiration, will help students to appreciate reasons for certain experimental procedures, graphical presentation of biological data, effect of temperature on enzyme-controlled reactions and a better understanding of the term "optimum temperature". It could be used after students have been taught the topic of Anaerobic Respiration.

The resource shows photographs of the experimental set up in which bicarbonate indicator solution was used to demonstrate the presence of one of the products of respiration in living organisms. It reinforces knowledge of the colour changes of bicarbonate indicator solution in the presence or absence of carbon dioxide. It could also be used to evaluate students' understanding of the topic of respiration.

This resource would be used to determine students' understanding of the mammalian kidneys and their functions of excretion and osmoregulation after the topics have been taught. It assesses students' ability to describe the structure of the kidney and the detailed structure of the nephron with its associated blood vessels.

The worksheet is for secondary level biology (ages 14 to 16 years and above). This could be used to deepen knowledge on osmosis in plant cells when immersed in solutions of different water potential, presenting the data collected in graphical form and using the graph to estimate the water potential of potato tissues. Answers have been provided to the questions.

The resource is mainly for A Level biology students. It may be used for homework or for assessment

This resource comes with well-illustrated photographs of a flower to help students to observe floral parts and answer questions set. It could be used as a worksheet or for assessment to see how students have understood topics on flower structure and functions and adaptations for pollination.

This resource could be used to assess students to find out how well they have understood the topics of gaseous exchange, inhalation and exhalation. Other topics like the differences in composition of inhaled and exhaled air as well as features of respiratory surfaces.

The resource involves the use of a potometer to demonstrate the measurement of water uptake by a leafy shoot and relate it to its evaporative water loss (transpiration). This is to help assess how well students have understood the processes of water uptake and transpiration by plants. It also aims to assess students on their understanding of the use of the potometer and how to minimise experimental errors.

This resource could be used to evaluate students understanding of the the tests for reducing and non-reducing sugars using Benedict's solution, test for starch, test for protein by Biuret's method and the emulsion test for fats and oils. Answers are provided.

This resource is for the assessment of students' grasp of the topic on seed structure and function. It could, in addition, be used to reinforce understanding of the topic. It also highlights seed structure and its use to classify plants as monocotyledons and dicotyledons.

The resource brings to mind the main function of the light microscope, its parts and their respective functions. It also deals with how the magnification of a specimen is determined.

The resource is useful for reinforcing understanding of how plants adapt to terrestrial habitats by minimizing water loss through transpiration. It deals with the adaptive features of xerophytes like Opuntia species.

T he resource could be used to assess students' grasp of the topic of photosynthesis and the plant organ that is adapted for this process. It gives more meaning to the definition of an organ (a group of tissues that perform a particular function). Students will appreciate that the leaf is the organ for photosynthesis and that the different tissues (epidermis, palisade mesophyll, spongy mesophyll, phloem, xylem) play their respective parts in photosynthesis.

This resource is for assessing students knowledge and understanding of the effects of sunlight on the development of green plants, such as the formation of chlorophyll. It could be useful in assessing the skills of observing, noting differences and reasoning to provide tangible explanation to observed phenomena by Advanced Level students of biology.
