Phloem cell type
Webb9 apr. 2024 · - Types of phloem are: - Primary Phloem: The phloem which is formed during the primary growth of the plant body is called the primary phloem. It is further of two types based on relative states of maturity, protophloem, and metaphloem. The first formed primary phloem is called protophloem and later formed is called metaphloem. http://www1.biologie.uni-hamburg.de/b-online/e06/06d.htm

Plant cells multiply by cell division, a mechanism known as Mitosis, which takes place within its nucleus. Webb(c) In plants, phloem is likely to be found in the stem and leaves as it is the tissue that conducts food, the manufactured food in the leaves needs to be transported to other plant parts. (d) Listed below are the functions of the labeled parts: 1: Sieve cell – assists in transporting food from leaves to storage structures and other plant parts.
