Phloem tissue adaptations
WebbPhloem: The living tissue in vascular plants that transports the soluble organic compounds such as the sugars made during photosynthesis throughout the plant is called the phloem. The transport of these photosynthates is referred to as translocation. WebbThe sporophyte of seedless plants is diploid and results from syngamy (fusion) of two gametes. The sporophyte bears the sporangia (singular, sporangium) (Fig. 4): organs …
