phloem tissue

• what is phloem tissue


  living tissue that transports sucrose and amino acids
• what are the 4 components that the phloem is made up of


  sieve tubes,companion cells,phloem fibres and phloem parachyma
• what is the function of sieve tubes


  transport sucrose and amino acids bidirectionally
• what is the function of companion cells


  these connect the sieve tubes via plasmodesmata
• what is the function of phloem fibres


  support
• what is phloem parechyma


  living tissue
• what are examples of organic compound that the sieve tubes would trnasport


  amino acids and sucrose
• what makes up the sieve tubes


  sieve elements and sieve plates
• what are sieve plates


  specialized tissue that allow nutrients to pass from cell to cell
• What are companion cells?


  Phloem cells that surround sieve tube elements
• what three ways are sieve tubes adapted


  a lot of mitochondria , pores allow the movement of cytoplasm and few organelles for space
