What are the different structures and functions of roots?
seraphim [82]

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.

A healthy Caribbean reef is home to over 50 species of coral and over 400 fish species. In this simplified model, we only consid
N76 [4]

Answer:

Without the model, we can't help you. But a healthy coral reef would most likely have some kind of productive ecosystem.

Explanation:

I would assume the the diagram includes a reference to fish, algae or other plant-like life, and the coral itself. The coral polyps are in a symbiotic relationship with algae; the algae provide the polyps with energy via photosynthesis and the polyps build "homes" for the algae and other species living in the reef (the "home" for algae is literally the coral reef).

Other species like animal life use the reef as a place of protection against larger predators. Fish frequent reefs since many types of aquatic predators dislike shallow waters and coral reefs provide plenty of nooks and crannies to hide inside.
