The cytoskeleton is a network of thin tubes and filaments that crisscrosses the cytosol. The tubes and filaments give shape to the cell from the inside in the same way that tent poles support the shape of a tent. The cytoskeleton also acts as a system of internal tracks, shown in Figure 4-18, on which items move around inside the cell. The cytoskeleton’s functions are based on several struc- tural elements. Three of these are microtubules, microfilaments, and intermediate filaments, shown and described in Table 4-2. Microtubules Microtubules are hollow tubes made of a protein called tubulin. Each tubulin molecule consists of two slightly different subunits. Microtubules radiate outward from a central point called the centrosome near the nucleus. Microtubules hold organelles in place, maintain a cell’s shape, and act as tracks that guide organelles and molecules as they move within the cell. Microfilaments Finer than microtubules, microfilaments are long threads of the beadlike protein actin and are linked end to end and wrapped around each other like two strands of a rope. Microfilaments con- tribute to cell movement, including the crawling of white blood cells and the contraction of muscle cells. Intermediate Filaments Intermediate filaments are rods that anchor the nucleus and some other organelles to their places in the cell. They maintain the inter- nal shape of the nucleus. Hair-follicle cells produce large quantities of intermediate filament proteins. These proteins make up most of the hair shaft. 84 CHAPTER 4 TABLE 4-2 The Structure of the Cytoskeleton Property Microtubules Microfilaments Intermediate filaments Structure hollow tubes made of two strands of intertwined protein fibers coiled into coiled protein protein cables Protein subunits tubulin, with two subunits: å actin one of several types of and ∫ tubulin fibrous proteins Main function maintenance of cell shape; cell maintenance and changing of maintenance of cell shape; motility (in cilia and flagella); cell shape; muscle contraction; anchor nucleus and other chromosome movement; movement of cytoplasm; cell organelles; maintenance of organelle movement motility; cell division shape of nucleus Shape Microtubules provide a path for organelles and molecules as they move throughout the cell.

Describe the organelles that are found in a eukaryotic cell. 4. Identify two characteristics that make mitochon- dria different from other organelles. 5. Contrast three types of cytoskeletal fibers. CRITICAL THINKING 6. Relating Concepts If a cell has a high energy requirement, would you expect the cell to have many mitochondria or few mitochondria? Why? 7. Analyzing Information How do scientists think that mitochondria originated? Why? 8. Analyzing Statements It is not completely accurate to say that organelles are floating freely in the cytosol. Why not? SECTION 3 REVIEW During cell division, centrioles organize microtubules that pull the chromosomes (orange) apart. The centrioles are at the center of rays of microtubules, which have been stained green with a fluorescent dye. FIGURE 4-20 Cilia and Flagella Cilia (SIL-ee-uh) and flagella (fluh-JEL-uh) are hairlike structures that extend from the surface of the cell, where they assist in movement. Cilia are short and are present in large numbers on certain cells, whereas flagella are longer and are far less numerous on the cells where they occur. Cilia and flagella have a membrane on their outer surface and an internal structure of nine pairs of micro- tubules around two central tubules, as Figure 4-19 shows. Cilia on cells in the inner ear vibrate and help detect sound. Cilia cover the surfaces of many protists and “row” the protists through water like thousands of oars. On other protists, cilia sweep water and food particles into a mouthlike opening. Many kinds of protists use flagella to propel themselves, as do human sperm cells. Centrioles Centrioles consist of two short cylinders of microtubules at right angles to each other and are situated in the cytoplasm near the nuclear envelope. Centrioles occur in animal cells, where they organize the microtubules of the cytoskeleton during cell division, as shown in Figure 4-20. Plant cells lack centrioles. Basal bodies have the same structure that centrioles do. Basal bodies are found at the base of cilia and flagella and appear to organize the devel- opment of cilia and flagella.

YouGov found 44 per cent were proud of Britain's history of colonialism, with 21 per cent regretting it happened and 23 per cent holding neither view. The same poll also found 43 per cent believed the British Empire was a good thing, 19 per cent said it was bad and 25 per cent said it was "neither". At its height in 1922, the British empire governed a fifth of the world's population and a quarter of the world's total land area. Although the proponents of Empire say it brought various economic developments to parts of the world it controlled, critics point to massacres, famines and the use of concentration camps by the British Empire. 1. Boer concentration camps During the Second Boer War (1899-1902), the British rounded up around a sixth of the Boer population - mainly women and children - and detained them in camps, which were overcrowded and prone to outbreaks of disease, with scant food rations. Of the 107,000 people interned in the camps, 27,927 Boers died, along with an unknown number of black Africans. 2. Amritsar massacre When peaceful protesters defied a government order and demonstrated against British colonial rule in Amritsar, India, on 13 April 1919, they were blocked inside the walled Jallianwala Gardens and fired upon by Gurkha soldiers. The soldiers, under the orders of Brigadier Reginald Dyer, kept firing until they ran out of ammunition, killing between 379 and 1,000 protesters and injuring another 1,100 within 10 minutes. Brigadier Dyer was later lauded a hero by the British public, who raised £26,000 for him as a thank you. 3. Partitioning of India In 1947, Cyril Radcliffe was tasked with drawing the border between India and the newly created state of Pakistan over the course of a single lunch. After Cyril Radcliffe split the subcontinent along religious lines, uprooting over 10 million people, Hindus in Pakistan and Muslims in India were forced to escape their homes as Some estimates suggest up to one million people lost their lives in sectarian killings. 4. Mau Mau Uprising Thousands of elderly Kenyans, who claim British colonial forces mistreated, raped and tortured them during the Mau Mau Uprising (1951-1960), have launched a £200m damages claim against the UK Government. Members of the Kikuyu tribe were detained in camps, since described as "Britain's gulags" or concentration camps, where they allege they were systematically tortured and suffered serious sexual assault. Estimates of the deaths vary widely: historian David Anderson estimates there were 20,000, whereas Caroline Elkins believes up to 100,000 could have died. 5. Famines in India Between 12 and 29 million Indians died of starvation while it was under the control of the British Empire, as millions of tons of wheat were exported to Britain as famine raged in India. In 1943, up to four million Bengalis starved to death when Winston Churchill diverted food to British soldiers and countries such as Greece while a deadly famine swept through Bengal. Talking about the Bengal famine in 1943, Churchill said: “I hate Indians. They are a beastly people with a beastly religion. The famine was their own fault for breeding like rabbits.”
