Description

This course focuses on understanding the nutritional processes in organisms, specifically how plants synthesize their food. Students will explore why organisms need food and understand the distinctions between parasitic and saprotrophic organisms. They will learn how to test for the presence of starch in leaves and gain an overview of the food synthesis process in green plants through photosynthesis.

The students will also discover that plants are the ultimate source of food, supported by visual aids and sketches.

The course covers key concepts, such as the role of chlorophyll in photosynthesis, the exchange of gases, and the storage of food in plants. Students will be introduced to different types of plants, including parasitic plants like Cuscuta and partially autotrophic plants. The students will understand the significance of pores (stomata) in leaves. The course includes fill-in-the-blank exercises and matching activities to reinforce understanding of terms like autotroph, heterotroph, and photosynthesis.

Students will evaluate true/false statements to test their knowledge. The students will also answer multiple-choice questions that will reinforce their understanding of these concepts. The course also addresses practical questions, such as why farmers grow many fruits and vegetable crops in large greenhouses, highlighting the benefits and advantages for agricultural productivity.
