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 .
  1. 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.
  1. 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.
  1. 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.
  1. 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.
  1. Function  - lateral roots originates from this zone and radial differentiation leads to secondary growth.

In order for plants and animals to be able to use nitrogen, N2 gas must first be converted to more a chemically available form.
pav-90 [236]

mario62 [17]

The correct option is C.

if two organisms are in the same class then they will be in the same phylum. The biological classification hierarchy is arranged in such a way that, two organisms who belong to a lower division on the hierarchy will automatically be in the same group in the higher division.

The arrangement from the smallest to largest hierarchy is this: specie, genus, family, order, class, phylum and kingdom.

k0ka [10]

Answer:

The whole body works together, as a “team.”If one of the parts of the body won’t work together as a team, everything will get messed up. The stomach muscles churn and mix the food with digestive juices that have acids and enzymes, breaking it into much smaller, digestible pieces. An acidic environment is needed for the digestion that takes place in the stomach.
