BIOLOGY ESSAYS FOR EASY REVISION. 1(a

Describe the digestion of a starchy meal along the human alimentary canal. S (13 mks) Answer-Starch in food is first broken down in the mouth by action of teeth/ chewing; This increases the surface area exposed enzyme action; saliva contains salivary amylase which breaks down some starch to maltose; saliva has a slightly alkaline pH which is optimum for the enzyme; The food moves down to the oespophagus and stomach; where the acidic pH, due presence of dilute Hcl, prevents further action of salivary amylase; In the duodenum, pancreatic amylase continues digestion of starch to maltose; Pancreatic amylase is produced in the pancrease; and enters the duodenum through pancreatic ducts; the acidic chyme is neutralized by the sodium bicarbonate in bile/ pancreatic juice; Maltose digestion continues in the ileum; whose walls secrete succus entericus/ intestinal juice; which contains enzyme maltase; which breaks down maltose to glucose; (Max 13 marks) (b) Describe the process of urea formation. (7marks) answer Excess amino acids / proteins; are transported to the liver 2. (a) Describe how gaseous exchange occurs in terrestrial plants. (13 marks) Answer Gaseous exchange takes place in a spongy mesophyl During the day air diffuses into large air spaces of spongy mesophyll; through stomata; the Carbon (IV) Oxide in the air diffuses into Photosynthetic cells; in solution form; during photosynthesis Carbon (iv) Oxide is used while oxygen is produced. Oxygen diffuses out of the leaf; through stomata; During the night; air diffuses into the air spaces (of spongy mesophyll), the air dissolves into film of moisture; then oxygen diffuses into the cells; and is used in respiration during which carbon (iv) oxide is produced, the Carbon (iv) Oxide diffuses out of the leaf; through stomata; due to concentration/diffusion gradient; Gaseous exchange takes place through epidermis (of young leaves and stems); epidermis of the root carries out gaseous exchange with air in the soil; some plants have pneumatophores/breathing roots; in which gaseous exchange occurs through lenticels; (found in

Absorption by Roots, Osmosis, and the Ascent of Sap • Roots and leaves are the main absorbing organs of the plant. ® Roots absorb water and minerals from the soil ® Leaves take in O 2 & CO 2 from the atmosphere • Reasons why plants need water: a) Turgidity-Cell sap in vacuoles lends rigidity to the plant b) Manufacture of food-Water is used as a raw material in photosynthesis along with CO 2 c) Translocation-Minerals absorbed by roots and carbohydrates prepared by leaves are transported in solution form d) Cooling of plant-When excess water is removed (by transpiration), the plant cools • Minerals and their Functions: a) Nitrogen-protein synthesis; growth b) Magnesium and iron-synthesis of chlorophyll c) Potassium-constituent of protoplasm; maintains osmotic balance in the cell; opening and closing of stomata d) Phosphorus-promotes nuclear and cell division e) Calcium-maintains the semi-permeability of the cell membrane f) Sulphur-constituent of amino acid (cysteine) g) Zinc-leaf formation • These minerals are taken in the form of ions/radicals; (Nitrogen absorbed as nitrates) • Functions of Roots: i. Fix the plant in soil ii. Absorb water and minerals from the soil iii. Conduct the absorbed substances through its tissues to the upper parts of plant • Adaptations of Roots: i. Branching nature-provides large surface area ii. Thin, freely permeable cell wall-allows movement of minerals in and out of cell by diffusion iii. Semi-permeable cell membrane-permits entry of water and restricts entry of salts by osmosis iv. Concentration of H 2 O in cell sap-in root hair is less than that of soil-helps in absorption of water by osmosis

Q1: On October 12, 1492 (the first day he encountered the native people of the Americas), Columbus wrote in his journal: "They should be good servants .... I, our Lord being pleased, will take hence, at the time of my departure, six natives for your Highnesses." These captives were later paraded through the streets of Barcelona and Seville when Columbus returned to Spain From his very first contact with native people, Columbus had their domination in mind. For example, on October 14, 1492, Columbus wrote in his journal, "with fifty men they can all be subjugated and made to do what is required of them." These were not mere words: after his second voyage, Columbus sent back a consignment of natives to be sold as slaves Yet in an April 1493, letter to Luis de Santangel (a patron who helped fund the first voyage), Columbus made clear that the people he encountered had done nothing to deserve ill-treatment.
