The correct sequence of plants which help in production of biofertilizers, medicines and protein food is:
Assertion (A): Biological control developed for treatment of plant diseases.
Reason (R): Trichoderma are free living fungi common in root ecosystem.
Assertion (A): Hydrophytes contain aerenchyma, which helps in gaseous exchange and buoyancy.
Reason (R): Mechanical tissues and xylem are poorly developed.

Identify the correct combinations from the following: 


 

Identify A, B, C, and D parts in the vascular bundle of monocot stem: 

Assertion (A): Phloem fibres (bast fibres) are made up of sclerenchymatous cells. 
Reason (R): Phloem fibres are generally absent in primary phloem but found in secondary phloem.

Assertion (A): Eukaryotic cells have the ability to adopt a variety of shapes and carry out directed movement.
Reason (R): Microfilaments, microtubules and intermediate filaments, constitute the cytoskeleton.
This type of cells are not present in phloem of a monocot stem.
