Слайд 1
Текст слайда:

Plant adaptations to habitats

Plants in different habitats possess different adaptations:

Mesophytes: plants adapted to a habitat with adequate water

Xerophytes: plants adapted to a dry habitat

Halophytes: plants adapted to a salty habitat

Hydrophytes: plants adapted to a freshwater habitat


Слайд 2
Текст слайда:

Hydrophyte:
Leaf undersurface of the tree fern. Extremely high number of stomata per unit in a species living in tropic cloud forests where is is very moist.


Слайд 3
Текст слайда:

Mesophytes do not have any specific morphological adaptations. They usually have broad, flat and green leaves; an extensive fibrous root system to absorb water; and the ability to develop perennating organs such as corms, rhizomes and bulbs to store food and water for use during drought.


Слайд 4
Текст слайда:

A halophyte is a plant that grows in waters of high salinity, coming into contact with saline water through its roots or by salt spray, such as in saline semi-deserts, mangrove swamps, marshes and sloughs and seashores


Слайд 5
Текст слайда:

A xerophyte is a species of plant that has adapted to survive in an environment with little liquid water, such as a desert or an ice- or snow-covered region in the Alps or the Arctic.

All Cacti are xerophytes

Natural Resources

Renewable resources

It is an organic natural resource which can be replaced to overcome usage and consumption, either through biological reproduction or other naturally occurring processes.
Eg: air, water, wind, solar energy, etc.

Non-renewable resources

Natural resources that cannot be replaced naturally at the same pace as it is being used.
Eg: Coal,oil, natural gas, wood, nuclear energy, etc.
