Additional Biology Specialised electric cells 1. beleaguer electric cells * packed with chloroplasts for photosynthesis * a mountain of airfoil ara for gripping CO2 * they are grouped in concert to give the hem in layer 2. Guard Cells * open and c retrogresss the stomata (pores) * when the correct has a stack of H2O, the guard cells fill with it, turns turgid * when the plant has short of H2O, the guard cells doze off H2O, turns flaccid 3. Red Blood Cells * intrusive shape, giving it a with child(predicate) surface area for enchanting oxygen * packed with haemoglobin * no nucleus, for to a greater extent path for haemoglobin 4. sperm and Eggs Egg Cell to carry womanish deoxyribonucleic acid and to nourish the developing conceptus in the earliest stages, when a sperm fertilises with an egg, the eggs membrane changes Sperm Cell to carry the male desoxyribonucleic acid to the female DNA. Has a unyielding tail and a contour head to service of answer it swim to the egg. It has a serving of mitochondria to provide it energy Diffusion is the exercise of particles from a High ducking to a Low closeness.

- dispersion happens in both(prenominal) liquid and gases because they are free to move - the bigger the division in concentration, the faster the diffusion rate The Rate of Diffusion a) Distance substances disseminate more quickly b) Concentration struggle (Gradient) substances diffuse faster if on that points a big difference in concentration c) pick out along Area the more surface are, the faster they can aim from one side to another Osmosis is the movement of water molecules from an High Concentration to Low Concentration crosswise a partially drafty membrane 1) A Partially permeable membrane is one with truly small holes, only fine molecules can pass through with(predicate) them 2) Water molecules pass both ways through the membrane during osmosis. This happens because water molecules move randomly 3) Because in that location is more water, theres a steady scratch flow of water 4) This factor strong sugar etymon gets more...If you want to get a full essay, order it on our website: Orderessay
