Chapter 2 : Cell Structure and Functions
The development of cell theory began with Robert Hooke coining the term "cell" after observing plant cells under a microscope. Robert Brown discovered that cells contain a nucleus. Matthias Schleiden and Theodor Schwann established that plants and animals are respectively composed of cells. Modern cell theory states that the cell is the basic unit of structure and function in living things, cells have similar components, new cells are formed via cell division, and cells in multicellular organisms are specialized to perform specific functions. Prokaryotes are cells without nuclei while eukaryotes contain nuclei.

Cell as the basic unit of life
Cells are the basic and smallest unit of life. A microscope is needed to see cells because they are so tiny. A microscope has lenses, clips, and a stage to hold samples, as well as focus knobs, to magnify cells and their structures, like the nucleus, cell membrane, and cytoplasm in cheek and onion cells. Different plant cells like onion cells have additional structures, such as a cell wall, chloroplasts, and vacuoles.
Cell is the Basic Unit of Life
The word cell is derived from the Latin word “cellula” which means “a little room”
It was the British botanist Robert Hooke who, in 1664, while examining a slice of bottle cork under a microscope, found its structure resembling the box-like living quarters of the monks in a monastery, and coined the word “cells”
cell the unit of life
Cells are the basic unit of structure and function of all living things. They contain organelles that allow specific functions like protein production, energy generation, waste digestion, and more. The cell membrane controls what enters and leaves the cell and provides structure and protection. Plant and animal cells differ in their additional structures - plant cells have cell walls and chloroplasts, while animal cells do not have cell walls.

CELL- STRUCTURE AND FUNCTIONS CLASS 8.pptx
Cell is the basic structural and functional unit of living organisms. Cells come in a variety of shapes and sizes depending on their function. A key discovery was made in 1665 by Robert Hooke who first observed "cells" in cork using a microscope. It was later determined that cells are the fundamental unit of all known living organisms. A typical cell contains a nucleus surrounded by cytoplasm which is enclosed by a cell membrane in eukaryotic cells. Organelles such as chloroplasts and mitochondria are also found within the cytoplasm and perform specific functions for the cell.

A Strategic Approach: GenAI in Education
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.
