Introduction Welcome to your preparation guide for this week’s practical lab session! Before we get hands-on with the equipment, it is crucial to understand the physiological principles that allow us to measure plant health, light environments, and photosynthetic rates. In the upcoming practical, we will demonstrate three essential scientific instruments: The Konica Minolta SPAD-502 Chlorophyll Meter The LI-180 Spectrometer The LI-6800 Portable Photosynthesis System Rea

Your task is to present and analyse the findings from our recent spectrometer experiment in the physiology lab. You will evaluate and compare the light readings taken from the top tier and the bottom tier, interpreting what these differences mean for plant physiological processes. Create a video about 10-15 min, with you or your group talking about the spectrometer values below. Use creative thinking to fashion your video, it could be a podcast interview style, a forum, a sho

Submit by group, not individually, so play nice, you all. A. [10%] Create a video about 10 to 15 min, with your group talking-teaching the public about the PGR topics assigned to you as follows: 1. Strigolactone POWER RANGERS 2. Brassinosteroid VERONICA 3. Jasmonate (IMUT PEOPLE) 4. Salicylates SUNFLOWER 5. Trehalose (TGP) UBI KAYU 6. Hydrogen Peroxide (H2O2) MATCHA LATTE Upload it to Google Drive, then provide me with a link to your uploaded video. Your video must

Whether it is a seedling pushing through the soil or a fruit ripening on a branch, every movement a plant makes is orchestrated by complex chemical messengers known as Plant Growth Regulators (PGRs) or Phytohormones. Derived from the Greek word hormaein, meaning "to excite," these natural molecules work in minute concentrations to produce substantial physiological changes. What Defines a Phytohormone? Unlike animals, plants do not have specialised glands for hormone product

Hi All, this is a reminder to submit your Test-1 on the 5th of May 2026 Remember to submit these 2 things: 1. The corrected version of the auto-generated transcripts (submit .srt file, keep the timestamps). Each person is responsible for 1 part of the 4 parts available (Photosynthesis The Light Reactions Part 1-4 of 4) Photosynthesis: The Light Reactions Part 1 of 4 reactions that occur within chloroplasts and the carbon fixation reactions that produce sugars. oxygen

https://youtu.be/PqQIvCWd6Dg Summary Technical training session established standardised ImageJ measurement protocols for quantifying auxin experiment root growth and length. ImageJ Setup and Scaling: Participants installed the ImageJ software and configured image scaling by setting rulers to establish consistent pixel-to-millimetre units. Counting and Measuring Roots: Researchers utilised multi-point tools for root counting and freehand tracing for curvature measurement. Ea

[10%] Answer Questions 1 to 40, find the answers in the picture and puzzle below, the words are in anagram form, find the anagram form and write the real words, then also find the answers in the crossword puzzles, highlight the answer using the pencil colour provided (Sample answers have been provided). B. [5%] Create a video about 10 min, with your group talking about anything that you have learned so far i

Original video: https://youtu.be/N8w_3odkJKg Lecture on: 19 Jan 2026 Master the essential tools for agricultural research and plant health monitoring. This lecture provides a detailed walkthrough of the LI-COR LI-180 Spectrometer and the SPAD Meter, focusing on how these instruments help quantify the "ALWNG" formula for plant growth and development. We explore the technical dimensions of light quality using the LI-180, covering the visible light spectrum from 400 to 700 nanom

Original video: https://youtu.be/TZpIZbKbylo Lecture on: 13 Jan 2026 Dive deep into the complex biochemical pathways that power plant life in this comprehensive lecture from AGR 3301. This session explores the critical relationship between the chloroplast and the mitochondria, mapping the journey of energy from carbon fixation to ATP production. We break down the transition of fixed carbon from the Calvin cycle into transportable sucrose and storage starch, followed by a deta

Original video: https://youtu.be/v-xTdfeac20 Lecture on: 3 November 2025 This lecture, part of the Crop Physiology (AGR3301) course, provides a deep dive into the properties of water, the movement of water within the plant (transport), and the fundamental concept of Water Potential. Water Properties and Transport. We begin by reviewing the unique characteristics of water, focusing on its role in plant function: 1. Polarity and Bonding: Water's polarity leads to hydrogen bondi

Original video: https://youtu.be/LTqGPldxdbI Lecture on: 13 October 2025 The first part of this lecture establishes the difference between plants (multicellular photosynthetic life-forms) and crops (plants grown in large quantities for commercial purposes). All crops are plants, but not all plants are crops. Key Focus of Crop Physiology Crop Physiology is the study of how plant organs (stems, roots, leaves, flowers, fruits, seeds) function, and the complex chemical processes
