Phloem is a type of plant cell responsible for transporting sugars, nutrients, and other organic compounds within a plant. It is not found in animals.
for example phloem .... doesnt have a nucleus ... and it needs a nucleus to survive ... thats why they have a companion cell which have a nucleus for them ...if u try to separate the companion cell from the phloem the phloem will die after some time
Companion cells found in phloem tissue have a nucleus. These cells are closely associated with sieve tube elements and play a role in supporting their function by providing energy and nutrients.
The phloem parenchyma cell contains a nucleus which helps in regulating its metabolic activities. These cells are involved in maintaining the osmotic pressure gradient within the sieve cell, aiding in the movement of sugars and nutrients in the phloem.
No, mitosis does not occur in the phloem. Mitosis is the process of cell division, and in the phloem, specialized cells called sieve elements are responsible for transporting sugars. These sieve elements are formed via a process called differentiation, not mitosis.
