PICTURES of the TERRESTRIAL ANIMALS

 

Flatworms (Planaria torva)

These animals move by beating cilia on the ventral dermis, allowing them to glide along on a film of mucus. Some move by undulations of the whole body by the contractions of muscles built into the body membrane.
Triclads play an important role in watercourse ecosystems and are often very important as bio-indicators.
The most frequently used planarian in high school and first-year college laboratories is the brownish Girardia tigrina. Other common species used are the blackish Planaria maculata and Girardia dorotocephala. Recently, however, the species Schmidtea mediterranea has emerged as the species of choice for modern molecular biological and genomic research due to its diploid chromosomes and the existence of both asexual and sexual strains. Recent genetic screens utilizing double-stranded RNA technology have uncovered 240 genes that affect regeneration in S. mediterranea. Many of these genes have orthologs in the human genome.

Types of Modern Garden Roses

            The different types of roses known as Modern Garden Roses are also divided into subdivisions.
These are the main types roses and types of roses for landscaping and home gardens. Most of them are repeat-flowering.
HYBRID TEA: Long-stemmed flowers that are high-centered. Usually one flower per stem. They bloom on upright, rather narrow plants, and flowers in flushes of every six weeks or so. This is the classic rose for cut flowers.

#7 #8 #9
GRANDIFLORA: These are tall and vigorous plants that produce flowers singly or in clusters. They are very similar to hybrid teas, except for their size.
Some Varieties and Colors:
#1 #2 #3
#4 #5 #6
POLYANTHA: Small flowered roses in large clusters on small compact free- flowering rose bushes.
SHRUBS: This is a large group of various classes, that vary widely in height and habit. This group include the English Roses by David Austin.
MINIATURES and MINI-ROSES: These are scaled down versions of the larger Modern Garden Roses, ranging in height from 6 inches to 2 feet tall. Their flowers and leaves are proportionally dimitutive.
CLIMBERS: A mixed group of roses with long arching canes that can be trained on a support such as arbors, trellises, fences, and walls.Some are repeat-flowering, some are not.

Different Kinds of Roses (OLD GARDEN ROSES)

Roses are prized for their for their lovely, often fragrant flowers.
Many rose types carry their blossoms in clusters, but some, notably hybrid teas tend to bear their flowers singly, one bud per stem.

ALBA: Mostly white flowered,or pale pink roses that only bloom once. The foilage is the color of sage green or grayish green.
BOURBON: The very first roses that repeat bloomed. They were introduced on the 'Isle of Bourbon' in the Indian Ocean. That's where these roses got the name. Bourbon roses are very fragrant.
CENTIFOLIA: Known as the 'Cabbage Roses', the flowers, looking like cabbages, usually have over 100 petals. These roses only bloom once.
DAMASK: The flowers are intensely fragrant and come in white, pink or red colors. Some repeat-flower, some don't.
HYBRID CHINA: These roses are tender and not for cold climates north of zone 7. Most are repeat flowering.
HYBRID GALLICA: These roses are almost always thornless. The once-flowering blooms are usually pink, red, or purple and have a strong rose fragrance.
HYBRID PERPETUAL: Very fragrant pink or red roses that repeat flowers.
MOSS: Mostly once-blooming fragrant roses that produce a sort of sticky moss-like growth on their flower stems and buds.
NOISETTE: Large, sort of sprawling rose plants that are best used as climbers. They have small clusters of fragrant flowers. These roses are cold-tender and best suited for warmer climates.
PORTLAND: Roses that are very fragrant, usually pink blooms that are repeat- flowering.
TEA: These roses have canes with few thorns. The flowers come in light yellow, pink or white colors and are repeat-blooming. Best in zone 7 and the south.
