Answer and Explanation:
Most young roots have two main regions. An outer cortex and a central cylinder containing the vascular bundles.
The endodermis also referred to as starch sheath. Its cells have a casparian strip which is made up of an impervious waxy deposit on the radial and cross walls. It controls entry of water and dissolved salts into the vascular bundle.
 
        
             
        
        
        
Answer:
Genotype of parents is Rr
Explanation:
Let the allele for red flower be represented by "R" and the allele for white flower be represented by "r"
Allele for red color is dominant over allele for white color. 
Co-dominant causes the expression of characteristics associated with dominant allele only. 
Genotype of parents is Rr
Rr * Rr
RR, Rr, Rr, rr
"rr" is white colored flower
"RR and Rr" is red colored flower
