It covers mitosis and cell division for growth, alongside cell specialisation and differentiation during development. The specification also introduces eukaryotes versus prokaryotes, microscopy techniques and electron microscopy, and includes required practical use of a light microscope plus calculations using magnification, real size and image size.","# 4.1 Cell biology\n\nCells are the basic unit of all forms of life.In this section we explore how structural differencesbetween types of cells enables them to perform specific functions within the organism.Thesedifferences in cells are controlled by genes in the nucleus.For an organism to grow,cells mustdivide by mitosis producing two new identical cells.If cells are isolated at an early stage of growthbefore they have become too specialised,they can retain their ability to grow into a range ofdifferent types of cells.This phenomenon has led to the development of stem cell technology.Thisis a new branch of medicine that allows doctors to repair damaged organs by growing new tissuefrom stem cells.  \n## 4.1.1 Cell structure\n\n### 4.1.1.1 Eukaryotes and prokaryotes\n\n\n| Content   | Key opportunities for  \u003Cbr>skills development   |\n| --- | --- |\n| Plant and animal cells (eukaryotic cells)have a cell membrane,  \u003Cbr>cytoplasm and genetic material enclosed in a nucleus.   |  |\n| Bacterial cells(prokaryotic cells)are much smaller in comparison.  \u003Cbr>They have cytoplasm and a cell membrane surrounded by a cell  \u003Cbr>wall.The genetic material is not enclosed in a nucleus.It is a single  \u003Cbr>DNA loop and there may be one or more small rings of DNA called  \u003Cbr>plasmids.   |  |\n| Students should be able to demonstrate an understanding of the  \u003Cbr>scale and size of cells and be able to make order of magnitude  \u003Cbr>calculations,including the use of standard form.   | MS 1b,2a,2h  \u003Cbr>WS 4.4  \u003Cbr>Use prefixes centi,milli,  \u003Cbr>micro and nano.   |\n\n### 4.1.1.2 Animal and plant cells\n\n\n| Content   | Key opportunities for  \u003Cbr>skills development   |\n| --- | --- |\n|  |  |\n| Students should be able to explain how the main sub-cellular  \u003Cbr>structures,including the nucleus,cell membranes,mitochondria,  \u003Cbr>chloroplasts in plant cells and plasmids in bacterial cells are related  \u003Cbr>to their functions.   | WS 1.2  \u003Cbr>Recognise,draw and  \u003Cbr>interpret images of cells.   |\n|  |  |\n| Most animal cells have the following parts:   |  |\n| ·a nucleus   |  |\n| ·cytoplasm   |  |\n| ·a cell membrane   |  |\n| ·mitochondria   |  |\n| ·ribosomes.   |  |\n| In addition to the parts found in animal cells,plant cells often have:   |  |\n| ·chloroplasts  \u003Cbr>·a permanent vacuole filled with cell sap.   |  |\n|  |  |\n| Plant and algal cells also have a cell wall made of cellulose,which  \u003Cbr>strengthens the cell.   |  |\n| Students should be able to use estimations and explain when they   | MS 1d,3a   |\n| should be used to judge the relative size or area of sub-cellular  \u003Cbr>structures.   | AT 7   |\n|  | Images of cells in videos,  \u003Cbr>bioviewers,photographs  \u003Cbr>and micrographs can be  \u003Cbr>used as comparison for  \u003Cbr>students own drawings.   |\n|  |  |\n\nRequired practical activity 1:use a light microscope to observe,draw and label a selection ofplant and animal cells.A magnification scale must be included.  \nAT skills covered by this practical activity:biology AT 1 and 7.  \nThis practical activity also provides opportunities to develop WS and MS.Details of all skills aregiven in Key opportunities for skills development (page 176).  \n### 4.1.1.3 Cell specialisation\n\n\n| Content   | Key opportunities for  \u003Cbr>skills development   |\n| --- | --- |\n\nStudents should be able to,when provided with appropriate  \ninformation,explain how the structure of different types of cell relate  \nto their function in a tissue,an organ or organ system,or the whole  \norganism.  \nCells may be specialised to carry out a particular function:  \n·sperm cells,nerve cells and muscle cells in animals  \n·root hair cells,xylem and phloem cells in plants.  \n### 4.1.1.4 Cell differentiation\n\n\n| Content   | Key opportunities for  \u003Cbr>skills development   |\n| --- | --- |\n| Students should be able to explain the importance of cell  \u003Cbr>differentiation.   |  |\n| As an organism develops,cells differentiate to form different types  \u003Cbr>of cells.   |  |\n| ·Most types of animal cell differentiate at an early stage.  \u003Cbr","cbCaipmQ6N34xv4C","https://ap.wps.com/l/cbCaipmQ6N34xv4C","pdf",1087743,1,5,"English","en",105,"# 4.1 Cell biology\n## 4.1.1 Cell structure\n### 4.1.1.1 Eukaryotes and prokaryotes\n### 4.1.1.2 Animal and plant cells\n### 4.1.1.3 Cell specialisation\n### 4.1.1.4 Cell differentiation\n### 4.1.1.5 Microscopy\n## 4.1.2 Cell division\n### 4.1.2.1 Chromosomes\n### 4.1.2.2 Mitosis and the cell cycle","[{\"question\":\"How does the nucleus control differences between cell types?\",\"answer\":\"Differences in cells are controlled by genes in the nucleus.
