Document Summary
Eucalyptus trees flammable 1 million in berkeley. Apomixis production of seeds without sperm and egg in the humble. Fragmentation creating separate plants from fragments of other plants dandelion. A diploid cell in the ovule produces an embryo, and the ovule matures into the seed. At roots, water and dissolved minerals get absorbed. Roots are good at filtering certain nutrients. Moist layer of soil in upper level (surface h2o) Roots have meristematic tissue (root apical meristematic tissue) Furthest deep is called the water table (aquifer) Root cap is a new phenomenon for us. Mucus secreted in root cap to help plant push down through soil. Root hairs are extension of epidermal layer (single-cell layer) Vascular tissue in the center of root. Endodermis is a band outside of vascular cylinder. Another name for vascular cylinder is called stele. Granules (statoliths) in root cells are heavy. Root grows toward direction of abundance of statoliths,
