The document discusses cells and their structures. It describes the structures of plant and animal cells, including their cell membranes, nuclei, cytoplasm, chloroplasts in plant cells, and cell walls in plant cells. It also explains the functions of cell organelles like ribosomes, endoplasmic reticulum, mitochondria and vacuoles. Specialized cell structures and functions are described for red blood cells, muscle cells, ciliated cells, xylem vessels, and root hair cells. Finally, it defines tissues as groups of similar cells, organs as structures of multiple tissue types, and organ systems as groups of organs that work together.

A Level Biology - Energy for Biological Processesmrexham
This is a free sample of a presentation that covers the whole of the topic energy for biological processes which includes respiration and photosynthesis.
It is written for the Edexcel Biology B specification but it will be suitable for most A Level courses.
This is a presentation designed to help explain the section of the Edexcel IGCSE Biology course about classification in the variety of living organisms section. For more help with IGCSE Biology please visit mrexham.com
This is the first PowerPoint in the mrexham IGCSE Biology series. It is also available on iBooks.
It covers the Cells section from life processes of the Edexcel IGCSE Biology course
Enzymes are biological catalysts. They play some of the most important roles in the processes of life sustenance. They are presence even at the tiniest level of metabolism - acting as the lubricant for life to progress smoothly. Without enzymes, complex life would not be possible.
Transportation of substances in and out of cells can be regulated by the single most underrated and under appreciated organelle in the cell - the phospholipid bilayer membrane.
IGCSE Biology - Chemical Coordination in Plantsmrexham
This PowerPoint answers the following questions:
Do you understand that plants respond to stimuli?
Can you give an example of positive phototropism?
How do plant roots and stems respond to gravity?
It covers section 3.3 of the IGCSE Edexcel Biology Course.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
