How whole plants are grown from a few cells: totipotency, the steps of micropropagation, types of tissue culture and its advantages.
The Origin of Life and the Role of Cyanobacteria
biowiz.biology@gmail.com
How the hostile early Earth gave rise to life, and how Cyanobacteria filled the atmosphere with oxygen in the Great Oxidation Event.
Teeth
biowiz.biology@gmail.com
The structure of a tooth, its four types, the terms used to classify dentition, and how milk teeth differ from permanent teeth.
Squamous Epithelium
biowiz.biology@gmail.com
Flat, tile-like epithelial cells: simple squamous epithelium for diffusion and stratified squamous epithelium for protection, with examples of each.
Sclerenchyma
biowiz.biology@gmail.com
The dead mechanical tissue of plants: features of sclerenchyma, its fibres and sclereids, and how its lignified walls give strength.
Pollen Grain
biowiz.biology@gmail.com
The male gametophyte of seed plants: the two-layered pollen wall, the vegetative and generative cells, and the advantages and disadvantages of pollen.
Osmosis, Osmotic Pressure, DPD and Water Potential
biowiz.biology@gmail.com
What osmosis is and the terms used to explain it: types of solution, diffusion pressure, osmotic and turgor pressure, DPD, and water potential.
Photosynthesis – Early Experiments
biowiz.biology@gmail.com
The journey to unravel photosynthesis has been full of groundbreaking discoveries! From Jan Ingenhousz revealing light’s role to Melvin Calvin mapping the carbon cycle, each finding has illuminated how plants convert sunlight into energy. These insights not only advanced science but also deepened our understanding of life’s green energy miracle.
Phospholipids
biowiz.biology@gmail.com
The structure of phospholipids: glycerol, fatty acid tails and the phosphate head, and how the X group decides the type of phospholipid.
