The heads consist of many individual flowers which mature into seeds‚ often in the hundreds‚ on a receptacle base. From the Americas‚ sunflower seeds were brought to Europe in the 16th century‚ where‚ along with sunflower oil‚ they became a widespread cooking ingredient. Leaves of the sunflower can be used as cattle feed‚ while the stems contain a fibre which

Enrichment Exercise 9 “The Private Life of Plants: Traveling” was a useful documentary to help clarify my understanding on how plants manage to spread their seeds and germinate. I enjoyed watching the different time lapses for the species of plants and it helped me to see exactly what happens rather than reading it in a book or seeing a simple picture. I was amazed at all the different mechanisms plants used to travel around and not stick to just one area. I did not expect the pointy spines of

The major variables with this study are proficient communications among the team‚ the seeds‚ soil‚ water concentration‚ fertilizer‚ light exposure‚ temperature of the room‚ consistency of following watering (watering the plant same time every day) and seed depth. All of these variables can affect the germination process in some sense but seed depth is the greatest‚ on the back of the seed packet it states

fungus emerges from its seed or spore. Germination involves activating the seed’s metabolism‚ which is done through numerous stages. The fist stage involves the rehydrating the cell by absorbing water. This allows the cell to become metabolically active. After water absorption‚ gibberellin is produced in the cotyledon of the seed. The enzyme gibberellin stimulates the production of amylase‚ which catalyzes the digestion of starch and converts it into maltose in the food the seed stores. Maltose is then

Effects of Sildenafil on Plant Growth using Brassica rapa seeds Introduction: Plant growth and development are affected by an overwhelming amount of factors in their environment but all these factors can be manipulated and given the perfect conditions the plant can grow to reach its peak size and potential. Rate of plant growth intrigued my fellow group members and I so it was decided that growth in mm as well as germination of the seed itself would be studied. With research being conducted into

STUDYING LANDSCAPE PATTERNS (FOCUSES ON THE USE OF GEOGRAPHICAL INFORMATION SYSTEM) WHAT IS GIS? A software program linked to a database containing massive amounts of geographic information. Common tool used in studying the spatial patterns of landscape. This tool was first developed in Canada in the 1960s for the “systematic digitization and scanning of maps‚ analysis of data‚ and output of new map products” (Tulloch 2000).

A gymnosperm (Greek for "naked seed") is a vascular plant that produces seeds that are not protected by fruit but are hidden in a woody cone. They do not have flowers‚ but most retain their leaves year round. Gymnosperms include over 600 species in four divisions: Conifers‚ Cycads‚ Ginkgoes‚ and Gnetophytes. Most of today’s gymnosperms belong to the conifer division. Gymnosperms are found in most of the world’s regions and take most of the credit for timber and paper products. Angiosperms

What Is It? At first glance‚ you may think it is a grain‚ but it is not. It is actually a plant seed in the Goosefoot Family (Chenopodiaceae)‚ which also includes spinach‚ beets and chard. These flat disc-shaped amino-acid rich seeds are loaded with nutrition. When cooked they are light and fluffy with a soft crunch‚ which makes them a great substitute for rice. These nutritious‚ amino acid-rich seeds are light and fluffy when cooked and come in a variety of colors (gold‚ red‚ and even black).

problem by producing sufficient quantities of food products by efficiently modifying plants to generate identically cloned plant material in the form of artificial seeds (Bewley‚ 1997). To accomplish the end goal of formulating artificial seeds‚ the somatic embryo of the plant must behave similarly to the zygotic embryo that exists in natural seeds (Martinez‚ 1986). Different factors have the potential to stimulate somatic embryos into zygotic embryos (Wu‚ 1994). The purpose of this experiment is to test
