The thylakoid in chloroplast are arranged as
interconnected disc
interconnected sacs
stacked discs
none of the above
C.
stacked discs
Most of the lamellae (folding forms a series of parallel membranous sheets) in the chloroplasts are organised to form sac like structures called thylakoids. These thylakoids may be stacked like a pile of coins, this formation has been termed as grana. Chlorophyll is found in grana and light reaction of photosynthesis occur in grana.
The non- photosynthetic, non- symbiotic N2 fixing bacteria are
Rhodobacter
Spirillum
Azotobacter
All of these
In monocot roots which types of vascular bundles are found?

Radial with exarch xylem
Bicollateral, conjoint and closed
Radial with endarch xylem
In bacteria respiration occurs in
cytoplasmic membrane
mitochondria
