Phloem specialised cells

Phloem tissue consists of conducting cells, generally called sieve elements, parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells and supportive cells, such as fibres and sclereids. Sieve elements are the type of cell that are responsible for transporting sugars throughout the plant. At maturity they lack a nucleus and have very few organelles, … WebbFör 1 dag sedan · Answer sheet with plant cells for students to write notes on . This resource can be used on KS3 or KS4 students.
