Trees

Pine cones close in response to changes in humidity, temperature, or the presence of moisture. Closing helps protect the seeds inside from harsh conditions, such as freezing temperatures or excessive moisture, until the environment is more favorable for germination.

Daffodils generate seed that are later fertilized by pollen to create new daffodils. This is a form of sexual reproduction. Another way daffodils reproduce is by producing bulbs called bulbils which can be planted by gardeners. This is an asexual form. So yes, daffodils can reproduce both asexually and sexually.

That would have to be a Lila grillacia, or more commonly known as the purple-bellied oak. They are found primarily in the northern parts of South America, most abundant in Argentinia, just bordering the Indian Pacific.

Alaska has the most trees in the United States, covering about 126.7 million acres of forested land. This is largely due to the state's vast boreal forest, which is the largest continuous forest in North America.

White birch trees grow well in the same conditions that produced the US Northern rain forests: generally cool temperatures, moist, sandy soils, and ample sunlight, although they tolerate a range of soil and site conditions.

Yes, Ginkgo trees are dioecious, meaning individual trees are either male or female and produce either male or female reproductive organs, not both on the same tree.

A bleeding tree refers to a tree that appears to be bleeding due to sap or resin oozing from its trunk or branches. This can be caused by physical damage, disease, or insect infestation. It is a natural defense mechanism of the tree to seal wounds and protect itself from further harm.

um idk. i searched this question. good luck finding it. :P

The role that plants trees have within their environment is to enable them absorb carbon dioxide during photosynthesis and release oxygen, also act as wind breakers and also act as home of other animals such as birds.

The sticky organic substance exuded by pine and fir trees is sap or rosin.

A rhododendron is a type of flowering shrub that is known for its large clusters of colorful blooms. They are popular in gardens and landscapes due to their beauty and ability to thrive in various climates. Rhododendrons are part of the Ericaceae family and have over a thousand different species.

The yellow birch (Betula alleghaniensis) is deciduous.

Tennessee's state tree is the Tulip Poplar (Liriodendron tulipifera). It was designated as the state tree in 1947 for its prevalence and economic importance to the state. The Tulip Poplar is known for its tall stature, distinctive tulip-shaped flowers, and its valuable timber.

Methuselah (estimated germination 2832 BC) is a bristlecone pine in the White Mountains of California, which, at 4,838 years old, is the oldest living organism currently known and documented. It is named after Methuselah, a Biblical figure reputed to have lived 969 years. Located at approximately 11,000 feet above sea level, its exact location is currently undisclosed to the public as a protection against vandalism; the coordinates cited refer to the Methuselah Grove Visitor Center. An older specimen, nicknamed Prometheus, was approximately 5,000 years old, but was cut down in 1964. Numerous claims of older plants of other species have been made, but these are all of clonal colonies, not individual plants. http://www.answers.com/methuselah%20tree%20 For a picture of the tree refer to the following link:metree-jpg

Trees come in lots of different sizes, and therefore, masses. A young tree might have a mass of a few kilograms, or even grams when it just starts to grow; larger trees can have many tons.

Photosynthesis takes energy from sunlight, carbon from atmospheric carbon dioxide, and hydrogen and oxygen from water molecules to form carbohydrates, most commonly molecules of the sugar, used in plants largely for structural support, Glucose.

The polymer of Glucose in plants is called cellulose, and the polymer of Glucose in animals is called glycogen. They differ only in the way the Glucose monomers are bonded together.

According to Wikipedia:

"...400 metres (1,300 ft) and 1,800 metres (5,900 ft)"

The bald cypress is native to the swampy areas of Louisiana, an unique evergreen that loses its needles in the fall. Beginning in colonial times, it was an important commodity in Louisiana. It was easy to work with and was used to build many things like furniture. It stood up well against water damage which was useful in Louisiana's climate. It was also used as a trade item building wealth for Louisiana residents.

Sacramento California has one of the highest per capita trees of any other city in the world, as does Nelspruit South Africa. The city is also planning to double its number of trees it has in the next 40 years. In terms of sheer numbers, Johannesburg South Africa is the most treed city in the world - with well over ten million trees. Toronto, Canada has 10.2 million trees. Large-scale operations in Beijing means it will too become very treed, although similar operations in Johannesburg mean that it is likely to retain the overall top spot comfortably.

Portland Oregon has a large arboritum and several large and small parks in its' city limits. Was considered the largest.

Conifers are a tree or shrub. Conifer trees spread over large areas of land, and so, play a major role in ecological balance especially in the Northern Hemisphere. So while their lives are not directly involved in most people's everyday life, these trees do play a vital role in how humans live. For example, these trees are numerous so they remove a lot of carbon dioxide from the air and give oxygen for human consumption.

Conifers are also a soft wood so they can be used by humans, especially for paper products.

Deciduous trees are those that shed their leaves every fall. Common examples include maple, oak, birch, and elm trees. This process is known as leaf abscission and is triggered by changes in daylight and temperature.

yes except white pin ,red pine and seder tree.
