If you use tables on your slides, ensure they are not overly complex and do not include blank cells. Transcripts can also be useful as an additional resource, but captioning ensures students can follow along with what is on the screen in real-time. All video and audio content should be captioned for students with hearing impairments.Alt text should describe the visual or table in detail so that students with visual impairments can “read” the images with their screen readers. All visuals and tables should include alt text.Since screen readers read what is on the page, you may want to consider creating a hyperlink using a descriptive title instead of displaying the URL. Use unique and specific slide titles so students can access the material they need.If you want to alter the layout of a theme, use the Slide Master this will ensure your slides will retain accessibility. Built-in slide template layouts were designed to be accessible: “the reading order is the same for people with vision and for people who use assistive technology such as screen readers” (University of Washington, n.d.). Student accessibility-students with visual or hearing impairments may not be able to fully access a PowerPoint presentation, especially those with graphics, images, and sound.

PART I: Designing the PowerPoint Presentation Accessibility ?iii) Reduction of carbon dioxide by hydrogen to form carbohydrates.This section is organized in three major segments: Part I will help faculty identify and use basic but important design elements, Part II will cover ways to enhance teaching and learning with PowerPoint, and Part III will list ways to engage students with PowerPoint. Of ? water molecules into hydrogen and oxygen. ? ii) Conversion of light energy into chemical energy and splitting up They are :- ? i) Absorption of light energy by chlorophyll. ? Chlorophyll ? Process of photosynthesis :- ? Photosynthesis takes place in three main steps. ? Equation of photosynthesis :- ? Sunlight ? 6CO The food prepared is carbohydrate which is stored in theįorm of starch. Using carbon dioxide and water in the presence of sunlight andĬhlorophyll. 4) Nutrition in plants :- ? Photosynthesis :- is the process by which plants prepare food by Eg :- amoeba, paramaecium,īirds, fishes, humans etc. ?iii) Holozoic nutrition :- is nutrition in which organisms take foodĭirectly and then digests and absorbs it. Orchids, ticks, lice, leeches, round worm, tape worm, plasmodium etc. ? ii) Parasitic nutrition :- is nutrition in which organisms get their foodįrom living organisms (host) without killing them. ?i) Saprohytic nutrition :- is nutrition in which organisms get their foodįrom dead and decaying organisms. They are saprophytic, parasitic and holozoic ?b) Types of heterotrophic nutrition :- There are three main types of ? Eg :- all animals fungi and some bacteria. ?ii) Heterotrophic nutrition :- is nutrition in which organisms get theirįood directly or indirectly from plants. ? Eg :- all green plants and some bacteria. Their own food from simple inorganic substances like carbon dioxideĪnd water in the presence of sunlight and chlorophyll. ?i) Autotrophic nutrition :- is nutrition in which organisms prepare TheyĪre autotrophic nutrition and heterotrophic nutrition. ?a) Modes of nutrition :- There are two main modes of nutrition.

Used by living organisms are food, water and air. ? Life on earth depends on carbon based molecules and most of theįood are also carbon based molecules. Utilisation by the body to build the body, for growth, to repair theĭamaged parts of the body and for energy. 3) Nutrition :- ? Nutrition is the process of taking food by an organism and its Waste products are carried from one part of the body to the other, ?iv) Excretion :- is the process by which waste products are removedįrom the body. ?iii) Transportation :– is the process by which food, oxygen, water, The body with the help of oxygen to release energy. ? ii) Respiration :– is the process by which food is burnt in the cells of Utilization by the body for life processes. ? i) Nutrition :– is the process of taking food by an organism and its Nutrition, respiration, transportation, and excretion. 2) Life processes :- ? Life processes are the basic processes in living organisms whichĪre necessary for maintaining their life. Molecular movements in cells and tissues is necessary for all life Some movements are not easily visible like molecular movements.

Some movements are easily visible like the movements of body parts. All living things move without the help of any external help. 1) Criteria to decide whether something is alive :- ? The most important criteria to decide whether something is alive is
