Agricultural Science, specifically the discipline of Agronomy, delves into the intricate world of plant forms and functions, a fundamental aspect of understanding crop production. In this course material on Plant Forms And Functions, we will explore the essential knowledge required to identify crop plant parts and their functions, as well as differentiate between monocot and dicot crop plants.
At the core of this topic lies the objective of enabling students to differentiate the various storage organs of crop plants. The storage organs of plants play a vital role in storing energy reserves and essential nutrients needed for growth and development. By comprehensively understanding these storage organs, students will be better equipped to optimize crop production and improve agricultural practices.
One key aspect we will cover is the anatomy and morphology of the storage organs of common crop plants. This includes examining the different parts of monocot and dicot crop plants and elucidating their functions. Monocot plants, such as corn and rice, exhibit a single cotyledon in their seeds, while dicots, like beans and sunflowers, possess two cotyledons. Understanding these distinctions is crucial for tailored agricultural practices and maximizing crop yields.
Moreover, we will delve into the factors affecting rock weathering and soil formation, which directly impact plant growth. Physical and chemical properties of soil, including soil water content, play a pivotal role in determining plant health and productivity. Students will gain insights into soil conservation, irrigation, drainage methods, as well as the roles of macro and micro-nutrients in plant nutrition.
Additionally, we will explore the living population of the soil, encompassing the vital roles of flora and fauna in maintaining soil fertility. Nutrient deficiency symptoms will be elucidated to help students identify and address potential plant health issues. Principles and practices of land preparation, soil tillage, and the factors influencing tillage methods selection will also be covered in-depth.
By the end of this course material, students will possess a holistic understanding of plant forms and functions, from the microscopic structures within storage organs to the overarching agricultural practices that influence crop production. This knowledge will empower them to make informed decisions in agricultural settings, driving sustainable and efficient farming practices.

(a) A farmer noticed that maize plants in a field began to wilt during the middle of a hot, dry afternoon, even though the soil still contained some moisture.
(i) State the name of the process by which water is lost from the leaves of a plant. [1]
(ii) Explain why the maize plants wilted during the hottest part of the day. [3]
