Plant Anatomy
First, we provide the students with theoretical differences between different types of tissues in a plant and point to the main differences between sections in stems or roots, and how to differentiate between them in both monocot and dicot plants, then we move to apply all this practically, examining different transition sections through different plants. We assist them to professionally ... Read more

In this course we start with Lab safety and precautions must be followed when dealing with hazard bacterial species. Give students the sterilizations basics. We teach them how to isolate bacteria from different sources (air, water and soil) and we give them an account about main nutrients required for bacterial growth with highlighting different types of media. A present them ... Read more

Industrial microbiology
We are assigned to teach the students 8 classes. The first class we teach them basics of sterilization and different types of growth media. The rest of classes we help them performing some useful experiments in the lab. Such as Yoghurt industry, kojic acid production and streptomycin synthesis. Discussions are opened through classes and a small report about all performed ... Read more

Physiology of fungi
The first 3 classes we teach the students how to isolate fungi from different sources (soil, air, water, breath) and help them prepare the medium required for growth and autoclave it. Then we give them an account on hoe to estimate fungal growth (inhibited or enhanced) using different methods. The effect of growth parameters essential for fungal growth are studied ... Read more

In the first class we are asked to provide students with an introduction about mycotoxins and give them an account about the course in whole. We help the students to do extraction for some mycotoxins and gain expertise in identifying theses toxins using TLC plates. Also, we help them to perform extraction of mycotoxins from important cereal crops (samples) and ... Read more

Genetics and Inheritance
The first 7 classes we are assigned to provide the students with Introduction about the DNA structure and different inheritance laws, showing them illustrating videos and high resolution images about the most important two divisions in a living cell (Meiosis and Mitosis divisions). Then we solve with them many problems about inheritance laws theoretically. The last two classes we show ... Read more

Classification of fungi
This course depends on microscopic examination of different fungal species to improve students’ experience in identifying fungi belongs to different fungal groups. Our task is mainly helping students to improve their skills using all available options in microscopes, providing them with key features of each fungal species after examination and periodically test their improvement through exams asking them to give ...

Plant pathology
We provide the students with data about important fungal plant pathogens, besides showing them illustrating videos each class. Putrified specimens are also provides to show them shape of infected plants in nature life. The syllabus inculdes the following class titles Wheat diseases Corn disease Cottony rot Onion disease Potatoes disease Apple disease Fruit disease Read more
