Question

Short note on phloem with their types and their functions

Answer 1

Phloem is the vascular tissue responsible for the transport of sugars from source tissues (ex. photosynthetic leaf cells) to sink tissues (ex. non-photosynthetic root cells or developing flowers). Other molecules such as proteins and mRNAs are also transported throughout the plant via phloem

Answer 2

phloem is a tissue in vascular bundle apart from xylem used for transportation of food from leaves to other parts of the plant. it is a complex tissue

it is of four types
1. sieve tubes - it is used to transport food from one cell to another
2.companion cells - used to control the movement of sieve tubes
3. phloem parenchyma - used to store excess food material
4. phloem fibres - only dead tissue in phloem . used to provide support
