Option 2 : Arrow C
Concept:
- Tissues in plants are classified into two main groups, namely, meristematic and permanent tissues based on whether the cells being formed are capable of dividing or not.
- Further Permanent tissues are also categorised into 2 types - Simple tissue & Complex tissue.
- The complex tissues are made of more than one type of cells and these work together as a unit.
- Xylem and phloem constitute the complex tissues in plants.
Explanation:
- Phloem is made up of five types of cells: sieve cells, sieve tubes, companion cells, phloem fibres and the phloem parenchyma.
- Sieve tubes are tubular cells with perforated walls.
- Except for phloem fibres, other phloem cells are living cells and, phloem fibre is the only dead element
- Phloem transports food manufactured in the leaves to other parts of the plant.
- This process of transport of food is called translocation.
- The food travels through the perforated sieve tube plates.
- Phloem can transport food in any direction based on the need, thus it is a multidirectional transport.
