Genes are DNA segments coding for specific traits, with the human genome having around 20,000-25,000 genes.

Genetics studies inheritance, variation, and gene expression, with DNA’s double helix structure discovered in 1953.

Transpiration aids in nutrient transport by generating suction in leaves, pulling up water from roots.

Plants control transpiration rate based on environmental factors such as humidity, temperature, and soil moisture.

Transpiration aids nutrient absorption and cools the plant by absorbing heat during water evaporation.

During photosynthesis, plants absorb sunlight and CO2, converting them into glucose and oxygen, and increasing atmospheric water vapor.

The xylem transports water and minerals in plants, while the phloem carries photosynthesis products.

Water moves from roots to leaves via capillary action, aided by cohesion, adhesion and tiny plant vessels.

Plants absorb water and nutrients from the soil, transporting them to the leaves via their vascular system.

Guard cells surround stomata, regulating transpiration rate by controlling the stomatal aperture size.
