Assignment 1: “The roles of phytochromes and cryptochromes in flowering.” Introduction: Light is vital for photosynthesis. It is necessary to direct plant growth and development. Light acts as a signal to initiate and regulate photoperiodism and photomorphogenesis. There are two light-sensing systems involved in these responses: a) the red light sensitive system (Phytochrome system) * Phytochrome is a plant photoreceptor. It is found in the leaves of most plants (including all

A group of dragon-flies were bustling about on their gaudy purple wings‚ intercepting the flight of a lone black bee or butterfly in search of sweetness from the flowers. The child followed them in the air with his gaze‚ till one of them would still its wings and rest‚ and he would try to catch it. But it would go fluttering‚ flapping‚ up into the air‚ when he had almost caught it in his hands. Then his mother

Wild purple flowers with yellow centers grow intermittently around the plants as if to bring a little color to the dryness of the landscape. I pause as a butterfly with large yellow and blue wings flutters from flower to flower‚ collecting pollen that the colorful flowers so graciously provide.

This is evident in the words flames‚ flamed and fire; and later in the poem feel‚ fall and flowers. Assonance is also very visible as is reflected later in the poem with words like they‚ today and away. Symbolism and pathos add to the poem making it a very poignant story. Williams uses irony and imagery from the beginning of this literature. It

cause. It is very obvious that bees play an important role in the ecosystem and for humans. Honey bees help the process of pollination. This process happens when a Honey Bee lands on a flower and transmits pollen grains (Male) to the stigma (Female) inside the flower. This happens everytime a bee lands on a flower. This process is more important than ever‚ due to the growing population of the earth and United States. The body of honeys bees make them excellent pollinators. Their fuzzy hair traps

including a number of species important to humans as food plants or ornamentals Distinct Flowers Monocots have distinctive morphological features that set them apart from the dicots. The flowers of monocot plants typically have petals‚ stamens and other floral parts in threes or multiples of three such as six or nine. Dicots have flower parts in multiples of four or five. The pollen grains from monocot flowers have a single furrow through the outer layers‚ while dicot pollen grains have three furrows

The Queen butterfly (Danaus gilippus)‚ is a communal and a all year-round butterfly in South Texas. It is in the family of Nymphalidae‚ which is the largest family of butterflies in the world. Closely resembling its cousin the monarch butterfly (Danaus plexippus)‚ it is smaller-sized and painted a darker shade of orange‚ and has two rows of white spots on the black borders of their wings.

are not only known to bloom all year round but they are also known to attract aphids. This not only causes for the flowers of the plants to look unappealing but they can also affect the growth of the plant. However‚ the problem that many rose bush owners have is that they do not know if growing a plant with the use of pesticides will be of benefit or if it will also degrade the flowers’ quality and the growth rate of the plant.

microsporogenesis and megasporogenesis. In what portion(s) of the flower does each of these processes occur? What is the end product of each process? Microsporogenesis produces our microspores. It occurs in the sporangia of the anther in flowers. Four haploid microspores are produced when the mother cell undergoes meiosis. Each microspore develops into a pollen grain. Megasporogenesis occurs in the sporangium of the ovule of a flower. After meiosis‚ the embryo sac is produced (egg‚ nucei‚ antipodal
