the cell membrane: The question being answered from doing this experiment is ‘How do different temperatures affect the permeability of the plasma membrane of beetroot?’ Beetroot contains red pigments called betalains‚ located within the cell vacuole. Normally the pigments cannot pass through membranes but they leak out when the beetroot is cooked or placed in alcohol. The aim of this practical is to use beetroot to examine the effect of temperature on cell membranes and relate the effects observed

the evil within (Sewlall 22-3). One significant dream in both novels is the all-consuming‚ “voracious” mouth (Epstein 208). In Lord of the Flies‚ “Simon found he was looking into a vast mouth. There was a blackness within‚ a blackness that spread” (Golding 144). In Heart of Darkness‚ Kurtz’s open mouth is described as “[giving] him a weirdly voracious aspect” (Conrad 90). These fantastic mouths are each symbols for evil encompassing all (Epstein 208). The statement of the intrinsic evil of human

Animal cells are round and irregular in shape while plant cells have fixed‚ rectangular shapes.

The plasma membrane surrounds the cytoplasm of living cells‚ physically separating the intracellular components from the extracellular environment. It also plays a role in anchoring the cytoskeleton provide shape to the cell‚ and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The plasma membrane helps maintain homeostasis by diffusion and osmosis. Osmosis is the diffusion of water across a membrane. Diffusion is the process by which molecules
