5. Shrubs a woody plant which is smaller than a tree and has several main stems arising at or near the ground. Although stems are tough, they are flexible but not delicate. Such plants have a long life span. Examples: Jasmine, rose, lemon, henna and tulsi .

6. Lack of a trunk: They branch near the ground, hence do not have a well-defined trunk and rather have many stems. Broad leave plants: Shrubs are usually as such. Hardy plants: They grow in all types of soil and are hardy. Shrubs are seasonal since they generally thrive in a sunny environment. Also, they are smaller than trees. Characteristics

9. Let's do some Question- Q1- How are the stems of shrubs? Q2- What are the two Characteristics of Shrubs?

10. Tundra Desert The  tundra  is a treeless polar  desert  found in the high latitudes in the polar regions Primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as sub-Antarctic islands. The region's long, dry winters feature months of total darkness and extremely frigid temperatures. Tundra is a treeless expanse that supports communities of sedges and heaths as well as dwarf shrubs Vegetation is generally scattered, although it can be patchy reflecting changes in soil and moisture gradients.  

11. Characteristics Extremely cold climate Low biotic diversity Simple vegetation structure Limitation of drainage Short season of growth and reproduction Energy and nutrients in the form of dead organic material

12. Large population oscillations Precipitation in the tundra totals 150 to 250 mm a year primarily in Alaska, Canada, Russia, Greenland, Iceland, and Scandinavia, as well as sub-Antarctic islands . very low mean annual temperature In mid-winter temperatures are as low as -40 to -50 °C  Summers are relatively warmer Characteristics

13. Plants in Tundra Region The plants tend to be small and close to the ground. This protects them from strong winds and cold temperatures.  Lichen also is found in the tundra. Some  plants  that grow in the  tundra  include short shrubs, sedges, grasses, flowers, birch trees and willow trees.

14. Arctic Moss Arctic moss, is an aquatic plant found on lake beds in tundra regions.  It has no wood stems or flowers and has small rootlets instead of roots. Arctic moss  is found in freezing temperatures  It can survive very strong winds

15. Pasque The pasque flower is a  low-growing ,  herbaceous   perennial .  It stands about 8 to 12 inches tall and forms a clump that spreads over time.  Its blooms precede most of its foliage in spring. The most common pasque has bluish-purple or dark violet flower.

17. Wildlife in Tundra Mountain Goat- The mountain goat, also known as the Rocky Mountain goat, is a hoofed mammal with sure footed climbers. Mountain goats  are powerful but nimble and can jump nearly 12 feet

18. Kea-  The kea is the only parrot living in the alpine regions of the world. This olive-green colored bird has bright orange under its wings and a gray upper beak that is narrow and curved Wildlife in Tundra

19. Musk Ox - shaggy-haired Arctic ruminant of the family Bovidae, are stocky mammals with large heads, short necks, and short, stout legs.  In winter, they use their hooves to dig through snow to graze on these plants. During the summer, they supplement their diet with Arctic flowers and grasses, often feeding near water. Wildlife in Tundra

20. Wildlife in Tundra Arctic Fox- Also known as the white fox, polar fox, or snow fox, it is a small fox native to the Arctic regions of the Northern Hemisphere and common throughout the Arctic tundra biome. It is well adapted to living in cold environments, and is best known for its thick, warm fur that is also used as camouflage.

21. Ptarmigan- any of three or four species of partridgelike grouse of cold regions, belonging to the genus Lagopus of the grouse family, Tetraonidae. They undergo seasonal changes of plumage, from white against winter snowfields to gray or brown, with barring, in spring and summer against tundra vegetation. Wildlife in Tundra

22. Wildlife in Tundra  A pika is a small, mountain-dwelling mammal found in Asia and North America. With short limbs, very round body, an even coat of fur, and no external tail, they resemble their close relative, the rabbit, but with short, rounded ears.
