Welcome to another lesson on agriculture business where we discuss water absorption systems in soil, focusing on infiltration and capillary action. This lesson explores plant physiology, detailing how roots, stems, leaves, and flowers function to absorb water and nutrients, enabling plant growth through processes like photosynthesis and fertilization. We also differentiate between fibrous and tap root systems with examples like carrots and onions, and discuss plant adaptations in harsh environments, such as cacti having large stems for water retention.
