What is Genotype?</h3>
An organism's genotype is made up of all of its genetic components. The alleles or variations that a person holds in a specific gene or genetic region are also referred to as the genotype.
The amount of copies of each chromosomes found in that species, also known as ploidy, determines how many alleles a person can have for a certain gene. In diploid organisms like humans, there are two complete sets of chromosomes, which means that each person has two different alleles for each gene. Homozygous refers to a genotype where both alleles are the same. Heterozygous refers to a genotype when there are two distinct alleles.
Phenotype, the observable qualities and attributes of an individual or creature, is influenced by genotype.

Different structures and functions of roots
Explanation:
Roots are the underground descending non-green part of the plant.
Root functions: Anchorages the plant to the soil, absorbs water and nutrients from the soil.
Characteristics: Positively geotropic and hydrotropic, negatively phototropic; does not have nodes, internodes or stems.
Types:
- Tap root
- Adventitious root – fibrous, foliar and true adventitious roots
Structure and functions:
- Root cap or Calyptra: Cap-like structure covering the root tip
.
- Function: protects the meristematic tissues of the root, secretes mucilage which enhances the root tips to grow into the hard soil.
- Meristematic zone or growing point sub-terminal behind root cap. These cells are inverted and looks like a dome.
- Function – helps in the root growth by adding new cells to the root tip and other basal regions
- Zone of elongation behind the meristematic zone.
- Function – helps in elongation of the root
- Root hair zone: This is the zone of differentiation where cells differentiate into vascular tissues like phloem, xylem, endodermis, cortex etc.
- The main function of root hair is to increase the total surface area of root to facilitate more absorption of water and other nutrients from the soil
- Zone of maturation: the major and mature portion of a root.
- Function - lateral roots originates from this zone and radial differentiation leads to secondary growth.
