BOTANY (100 MARKS)
I. Algae, Fungi, and Bryophytes
- Phycology (Algae): Study of algae including their types, where they are found, how they are structured, their life cycles, and how they are useful to people.
- Mycology and Plant Diseases: Study of fungi—how they are built, how they reproduce, their classification, and how they help or harm us. Also includes diseases that damage important crops and general ways to control them.
- Bryology (Bryophytes): Structure and reproduction of simple land plants like mosses. Also covers how their reproductive systems have developed over time.
II. Pteridophytes and Gymnosperms
- A general overview focusing on the structure, life cycle, and relationships of pteridophytes (like ferns) and gymnosperms (cone-bearing plants).
- Study of how seeds form and develop.
- Classification and uses of gymnosperms in daily life.
III. Plant Anatomy and Embryology
- Study of plant tissues—both primary and secondary.
- Types of meristems (tissue that helps plants grow).
- How dicot stems grow in thickness (secondary growth).
- Internal structure of leaves, stems, and roots.
- How male and female spores are formed, pollination, fertilization, and how seeds develop.
- Seed dispersal methods.
IV. Angiosperm Classification (Taxonomy)
- Systems used to classify flowering plants (angiosperms).
- Rules for naming plants correctly.
- How new plant species form.
- Modern techniques in classification, such as using chemicals, genes, and numbers.
- Key features and uses of common plant families.
V. Plant Physiology
- How plants manage water, including absorption by roots and loss by transpiration.
- The role of minerals in plant health and how they are absorbed.
- Hormones in plants and how they affect growth.
- Effects of light and cold on flowering (photoperiodism, vernalization).
- Dormancy and seed germination.
- Enzymes and how they work in plants.
Photosynthesis:
- Types of plant pigments.
- Light-dependent reactions.
- How carbon dioxide is used to make sugars.
- How light energy is turned into chemical energy.
Respiration:
- Breakdown of sugars in glycolysis and the Krebs cycle.
- How energy is released through oxidative phosphorylation.
VI. Ecology
- How climate, soil, and living things affect plant growth.
- Methods for studying plant communities.
- Ecosystem concepts, productivity, energy flow, food chains, and food webs.
- Nutrient cycles like the water cycle and nitrogen cycle.
- Natural changes in ecosystems (succession).
- Causes and solutions for soil salinity and waterlogging in Pakistan.
- Problems like soil erosion and deforestation, and how to prevent them.
- Conservation of biodiversity and dealing with pollution.
VII. Cytology (Study of Cells)
- Cell cycle and structure of plant cells.
- Chemistry of cell walls and membranes.
- How plant cells communicate.
- Growing plant cells in labs.
- Cell aging and death.
- Detailed structure of cell parts like mitochondria, Golgi bodies, ER, plastids, ribosomes, glyoxysomes, vacuoles, and nucleus.
VIII. Genetics
- Basic laws of inheritance (Mendelian genetics).
- Inheritance involving more than two alleles and many genes.
- How different genes interact.
- Inheritance of traits linked to sex chromosomes.
- Changes in chromosomes and mutations.
- How DNA damage is repaired.
IX. Evolution
- What evolution is and how life has evolved over time.
- Different types of evolution: convergent, divergent, and parallel.
- Role of natural selection in shaping life.
X. Molecular Biology
- Structure and role of DNA and RNA.
- DNA as the material that carries genetic information.
- How DNA copies itself.
- How genetic information is used to make proteins (transcription, genetic code, translation).
- Genetic engineering and its uses.
- Genetically modified organisms (GMOs).
