           PLANT KINGDOM

In the biological classification we looked at the broad classification of living organisms under the system proposed by Whittaker 1969.

Which suggested the five kingdom. 

• algae ,bryophytes, pteridophytes ,gymnosperms and angiosperms under plantae.

✓ gross superficial morphological based mananiy on vegetative characters on the the roecium structure system given by Linnaeus such system are artificial. 


✓ artificial system are gave equal weightages to vegetative and sexual characteristics this is not capable since we know that often the vegetative characters are more easily affected by environments.


✓  external features but also internal features like ultra structure anatomy embryology and phytochemistry such as classification for flowering plants was given by George Bentham and Joseph delton hooker.


✓ phylogenetic classification system based on evolutionary relationship.

✓ same taxa having a common and ancestors.

✓ Numerical taxonomy which is number and course are assigned to all the characters and the data.

✓ cytotaxonomy is based on the site or logical information like the chromosome number structure behaviour.

✓ chemo taxonomy that uses the chemical constituents of the plants.

A - Loose smut and ergot are two distinct diseases affecting wheat, each caused by different pathogens and exhibiting unique symptoms. ### Loose Smut of Wheat **Pathogen:** *Ustilago tritici* **Symptoms:** 1. **Early Appearance:** Symptoms are noticeable at the time of heading. 2. **Smutty Spikes:** Infected spikes (ears) emerge from the boot earlier than healthy ones. The entire spike, including the grains, is replaced by a black, powdery mass of smut spores. 3. **Powdery Mass:** The black spores are easily dispersed by wind, leaving only the bare rachis (central

B Define fungi Fungi are a diverse group of organisms belonging to the kingdom Fungi, which includes about 144,000 known species. They encompass various organisms such as yeasts, mildews, molds, and mushrooms. Fungi are eukaryotic, meaning they have cells with a nucleus enclosed within membranes. They reproduce through spores and often have a rigid cell wall made of chitin. The scientific study of fungi is known as mycology. C Draw the disease cycle of potato. D. Mention the symptoms of black rust Black rust is a plant disease that affects crops like wheat. The symptoms of black rust include: 1. Reddish-brown pustules on the wheat stem that turn black as they
