The layer of parenchyma surrounding a vascular bundle is known as:
1 bundle sheath
2 bundle shield
3 bundle parenchyma
4 bundle fibre
Explanation:
Exp:A The layer of parenchyma surrounding a vascular bundle is known as ' bundle sheath'. The bundle sheath cells are a layer of cells found in plant leaves and stem. These cells form a sheath around the vascular bundles. These are consist of chloroplasts and are key sites of the Calvin cycle. In dicots the bundle sheath parenchyma also called border parenchyma.

Collenchyma differs from sclerenchyma
1 retaining protoplasm at maturity
2 having thick walls
3 having wide lumen
4 being meristematic
Explanation:
Exp:A Collenchyma differs from sclerenchyma due to the retaining protoplasm at maturity collenchyma cells contain protoplasm and do not have any intercellular spaces. Sclerenchyma is made up of dead cells with thick walls. Sclerenchyma cells do not have protoplasm, these cells are lignified and strong secondary cell wall and are usually dead at maturity.

Which of the following is related with transfer of food material?
1 Xylem
2 Collenchyma
3 Phloem
4 Parenchyma
Explanation:
Exp:C 'Phloem' is related with transfer of food material. The main functions of these tissues (Phloem) are transports of food material and mechanical support to the plants phloem is a complex permanent tissue present in higher vascular plants.

Which of the following is enucleate at maturity?
1 Cortical cell
2 Cambial cell
3 Meristematic cell
4 Sieve tube cell
Explanation:
Exp:D 'Sieve tube cell,' is enucleated at maturity. A mature sieve cell or sieve tube element lack nucleus thus these are enucleated living cells. Sieve tubes are considered living cells without a nucleus because the nucleus of companion cells controls their functional activities. The main function of sieve tube the transport of carbohydrates primarily sucrose, in the plant.
