Unformatted text preview: ls phloem- sugar) ground- includes cells specialized for storage, photosynthesis, and transport 10. Xylem conducts water and dissolved minerals from roots to shoots. Phloem transports sugars to roots and growth sites, such a developing leaves and fruits. Tracheids and vessel elements are cells of the xylem while sieve-tube elements & companion cells are part of the phloem. Xylem and phloem are similar because they both are part of the vascular tissue system which carries out long-distance transport of materials between the root and shoot systems. Both are composed of a variety of cell types, including cells that are highly specialized for transport or support. They differ because xylem conducts water and phloem transports sugars. 11. “Indeterminate Growth” is a major difference between plants and most animals because a plant is not limited to an embryonic or juvenile period. Instead growth occurs throughout the plants life. indeterminate growth- plants never stop growing 12. The three zones of a cell in which growth occurs are the zone of cell division, zone of elongation, and the zone of maturation. The zone that is primarily responsible for pushing the root tip through the soil is the zone of elongation. growth zones of a cell = cell division, elongation, maturation 13. The functions of root cap are to protect the delicate apical meristem as the root pushes through the abrasive soil during primary growth and it secretes a polysaccharide slime that lubricates the soil around the tip of the root. root cap protects apical meristem as it pushes through soil 14. The function of the leaf stoma is to allow gas exchange between the surrounding air and the photosynthetic cells inside the leaf. leaf stoma allows gas exchange between air and inside leaf 15. Woody plants grow in girth parts of the stems and roots that no longer grow in length; secondary growth, due to activity of lateral meristems. The tissu...
