Study Notes
Circulatory System
- The circulatory system in humans consists of the heart, blood, and blood vessels, responsible for transporting materials like oxygen, carbon dioxide, food, and excretory products.
Transport in Plants
- In highly differentiated plants, transport of water, minerals, food, and other materials is a function of vascular tissue, consisting of xylem and phloem.
Excretion
- Excretion is the biological process of removing harmful metabolic wastes from the body.
- Different organisms use varied strategies for excretion, such as simple diffusion in unicellular organisms and specialized organs in complex multi-cellular organisms.
Excretion in Human Beings
- The excretory system in humans includes a pair of kidneys, a pair of ureters, a urinary bladder, and a urethra.
- Kidneys are located in the abdomen and play a crucial role in removing excretory products, such as soluble nitrogen compounds.
Transport of Food in Plants
- Translocation is the transport of soluble products of photosynthesis from leaves to other parts of the plant, occurring in the phloem part of vascular tissue.
- Phloem transports amino acids and other substances to storage organs, fruits, seeds, and growing organs.
- Translocation occurs in sieve tubes with the help of adjacent companion cells, using energy from ATP to increase osmotic pressure and move materials.
