3. Were do seeds come from? • They mostly come from other flowers, plants, vegetables and fruit Bibliography : http://wiki.answers.com/Q/Where_do_seeds_come_from

4. How does pollination work? • The male part of a plant is the one that produces the pollen. Some plants rely on the wind to carry their pollen. Some rely on rain or water to splash the pollen where it needs to go. The most popular method is by insects though. Insects, like bees, will stop by on a flower and when they do this the pollen sticks to their legs and is transported to the female part of a flower.

5. Why do plants need water, sun and oxygen? • plants use the light energy (with the help of carbon dioxide and water) to create glucose, a kind of sugar, to keep the plant alive, and oxygen. Water is needed to make the chemistry behind all life possible. Plants (and everything else) use water to transport all those metabolic products to where they are needed and to get nutrients from the surroundings. Plants also use water to make food for us in photosynthesis where water molecules and carbon dioxide molecules combine to form glucose and oxygen. Plants respire exactly the same way that animals do. If they don't have oxygen plants will suffocate and die within a few hours.

6. Are there deadly plants in NZ? • Yes there are and here are the top 10 most poisonous • Arum Lily • Black Nightshade • Euphorbia • Iris • Oleander • Agapanthus • Ongoing (New Zealand Tree Nettle) • Hemlock • Foxglove • Rhys Bibliography: http://poisons.co.nz/fact.php?f=12

7. How will we know a plant is poisonous? • Take a cutting of that plant, go to your local nursery and get the name of the plant and either ask them or look it up on the web. If you have children it's best to get to know what plants are around the play area and if any should be poisonous it's best to get rid of them. plant part you choose appears contact-poisonous, you may immediately test a new plant on your other arm or behind your knee. If the plant causes a reaction before you swallowed it, wait until the symptoms have disappeared before testing a new plant. If you have an adverse reaction after you've swallowed the plant, wait until symptoms have disappeared and start a new test. Although there may be edible parts of the plant you initially chose, it is preferable to move on to a different plant for subsequent tests. bibliography: http://wiki.answers.com/Q/How can_ you_tell_if_a_plant_is_poisonous

8. Interesting facts about daffodils • Daffodils are members of the Narcissus family. • All parts of the daffodil are poisonous. • The sap of daffodils can be damaging to other flowers. If you’ve picked them to display in a vase with other flowers, then it’s best to leave them in water on their own for at least 12 hours, before mixing them together. • In New York, nearly 2,500,000 daffodils are grown each year Bibliography: http://www.hotfact.com/facts_about_daffodils.html

9. What’s the difference between a fruit and a vegetable • A fruit is actually the sweet, ripened ovary or ovaries of a seed-bearing plant. A vegetable, in contrast, is an herbaceous plant cultivated for an edible part (seeds, roots, stems, leaves, bulbs, tubers, or non sweet fruits). So, to be really nit picky, a fruit could be a vegetable, but a vegetable could not be a fruit. The Nutriquest team offers a similar answer, adding that most fruits are sweet because they contain a simple sugar called fructose, while most vegetables are less sweet because they have much less fructose. The sweetness of fruit encourages animals to eat it and thereby spread the seeds. The site also presents an interesting list of fruits that are often thought to be fruit • tomatoes • cucumbers • squashes and zucchini • avocados • green, red, and yellow peppers • peapods • pumpkins Bibliography: http://ask.yahoo.com/20010411.html

10. What do plants need to make food • There are a few things that plants need to make food. Sunlight and water are the most important resources that are needed in order to for them to produce food. http://answers.ask.com/Home/Gardening/what_do_plants_need_to_make_food

11. Interesting facts about moss/lichen/fern • Moss: They commonly grow close together in clumps or mats in damp or shady locations. They do not have flowers or seeds, and their simple leaves cover the thin wiry stems. Lichen: A lichen is not a single organism, but the result of a partnership (mutualistic symbiosis) between a fungus and an alga or cyanobacteria Ferns: they thrive in a variety of climates and locations. These lush, green plants make up a major portion of the native flora in high mountain forests, as well as tropical jungles. Bibliography: http://www.ehow.com/info_7945050_interesting-ferns.html

12. What does the word pollination mean? • to Transfer of pollen from the anther to the stigma of a plant Bibliography: http://www.audioenglish.net/dictionary/pollination.htm

13. connect • How dose it work? • Well, it all begins in the flower. Flowering plants have several different parts that are important in pollination. Flowers have male parts called stamens that produce a sticky powder called pollen. Flowers also have a female part called the pistil. The top of the pistil is called the stigma, and is often sticky. Seeds are made at the base of the pistil, in the ovule. Bibliography: http://www.audioenglish.net/dictionary/pollination.htm

14. connect • In botany a fruit is the developed ovary of a seed-bearing plant. That would include apples, oranges, peapods, tomatoes, and even nuts. The term vegetable does not have a particular botanical meaning.In a culinary definition, a vegetable is a part of a plant (which can be a stem, a root, a leaf or a fruit) that is generally served as an accompaniment to meat or fish or as part of the main part of a meal. Under that definition, some fruits are generally considered vegetables, like tomatoes or peapods, or green beans. Other fruits, usually the soft, sweet ones, are generally served as part of dessert or as an appetizer. There are certainly exceptions, because meats or fish may sometimes be flavoured with fruits like lemon or orange, but we still consider those fruits. Nuts are botanically fruits, but we consider them a separate culinary category. Grains are parts of plants but not considered vegetables but also a category of their own. So fruit vs. vegetable vs. something else is not always completely clear-cut. Bibliography: http://ask.yahoo.com/20010411.html

15. connect • They’re one of the easiest flowers to grow and provide a lovely display of colour in the spring. The emblem of Wales is the daffodil. • People often wear daffodils on St. David’s Day. • In New York, nearly 2,500,000 daffodils are grown each year. • The Victorians thought daffodils acted as a symbol of regard. • Prince Charles, from the British Royal Family, is annually given one daffodil to act as a form of rent for land on the Isles of Scilly. • Daffodil bulbs contain a substance called galantine, which has medicinal properties. In fact, it’s sometimes used in treatments for Alzheimer’s. • In Australia, they have an annual Daffodil Day to help raise awareness about cancer. The daffodil is also used as a symbol by Marie Curie Cancer Care in the UK. Bibliography: http://www.hotfact.com/facts_about_daffodils.html
