The root tops the trunk on this backwards thing, that grows in the winter and dies in the spring..?

New buds push off old leaves and new buds begin forming in the fall.  Some species have big buds and others smaller buds.  All buds begin to swell in the spring just before the buds begin bursting, which pushes off any remaining leaves still attached.\n\nWith some species (maple and beech and surely others), the new bud developed in the fall simply doesn't push the leaves off until they begin swelling in the spring.\n\nThere is a term for this, but I don't remember it.

Dude / dudette.\n\nCheck your local search engine.\n\nWatch a plant in your garden, for gawdsakes.  Plants wilt without water, so it's a fair bet that water fills the cells - perhaps the cell walls?\n\nHere's a passage ripped off from a website:\n\nWater acts as a SOLVENT for minerals and stored food that must be moved through the plant. Water evaporation on the leaf surface helps cool the plant during very hot weather in the same way that perspiration keeps us cool. \n\nPlants even require water during winter. Water is absorbed through and stored in roots for winter. When soil is frozen, water movement is very restricted. On windy winter days, leaves of broadleaf evergreens, such as rhododendrons, may curl to reduce water loss. Curling reduces the amount of leaf surface exposed to drying winds, reducing evaporation. Continued water loss may cause tissue to die and turn brown. This kind of plant injury is called desiccation. It is critical that broadleaf evergreens have an adequate supply of soil moisture going into winter.

AGE OF THE TREE the rings inside 1 per year \nhurbs  dont know

the cells in the tree will still be alive right after it's cut from the roots, so it will die some time after that

Not true, if you remove the cambium of a tree al around it's girth it will die because the cambium contains the phloem and xylem vessels that transport nutrients and water to the higher parts of the tree.  It is called 'ringing'.  Is why they put protection around saplings so the rabbits can't munch on it and inadvertetly kill the sapling.

plant it in the ground like a seed. not really, i'm just kidding you.  You should put it into an Annuity, you can't touch it or you will be penalized, it will grow, slowly, but not too slowly and it will mature i think whenever you want it to.

Primary Growth: Apical meristem is responsible for primary root and stem growth in vascular plants.\n \nPrimary Root Growth: is concentrated near the tip and results in the root growing in length. The root tip contains 4 zones of development: The root cap, which protects the area behind it and softens the soil ahead of it by producing a polysaccharide. The apical meristem, is an area of rapidly dividing cells. It will replace the cells of the root cap as they wear away and push cells above them that will develop into the main tissues of the plant. The zone of elongation, is an area where the cells elongate 10 times their original length. This elongation helps push the root into the soil. The zone of maturation, is the area farthest from the root tip. Here the new cells will specialize and carry out the functions of the epidermal, ground, and vascular tissue. The primary tissues in a dicot root are arranges in a central x pattern for the xylem with the phloem located in each of the angles of the xylem. In a monocot the vascular tissues are alternated in a circle.\nPrimary Stem Growth: begins at the tip of the terminal bud in the area called the apical meristem. The cell divisions are responsible for the stem's growth in length. The primary vascular tissue in monocots takes on a scattered arrangement. In a dicot, it takes a circular pattern.\n \nSecondary Growth: Increases the girth of a stem it is caused by the vascular and cork cambium.\n \nVascular Cambium: meristematic parenchyma produces xylem on the inside and phloem on its outer side. The secondary xylem accumulates and forms the wood. The secondary phloem does not accumulate and is sloughed off with the bark.\nCork Cambium: forms in the outer cortex. Produces cork and epidermal tissues.\nWood has 2 zones: Heartwood- the older (inner) layers of xylem blocked with resins. It is non -functional in water transport. Sap wood- outer xylem, vascular cambium, phloem and cork cambium. Conducts water and food.

Their roots are actually specialized branches (rhizoids) that grow in the ground or into tree bark, on rock, etc. so the whole plant is actually living sideways.  The branches absorb water just like roots would. They have a great capacity for storing water, and most are pretty small, so they don't need as much rain as most plants, just humidity/moistness.  Most surfaces are wet with dew in the morning, and they absorb this.

The basic problem for trees surviving the winter in colder climates is that the water they need for transporting nurishment freezes.  There are two ways that trees survive through the winter:\n\n1)Deciduous trees: They basically go into hibernation for the winter.  They loose there leaves and have buds ready to go the next year.  So they to not need the excess nurishment durning the colder months.\n\n2) Evergreen Trees have leaves that are adapted to retainng water during the cold months either a waxy film or by shape.\n\nBoth types keep the truncks of the tree from cracking because of freezing sap by creating more sugars in the sap which causes the freezing point of the sap to drop.

The "walking tree".\n\nThis tree has no central root as such and it stands on a large number of roots that grow close to or above the ground.\n\nThese roots tend to grow more on the side where there is light, and so if, for example, there seems to be more light to the west, more roots will grow on the west side and gradually the plant will move in that direction.\n\nThe trees can move up to 15 centimeters a year. This is an example of positive phototropism, that is, the tendency of plants to grow or turn toward light.\n\nBananas probably do something similar and I presume the direction is usually towards the equator.

It's called the "root".

they are dead.\n\njust like dead tree limbs, they fall off in time.\nit's called gravity.\n\nthe tree goes dormant, the leaves are not needed any longer for this year.\n\nthe leaves are dead and gravity will pull them to the ground

It stops plant growth, meaning at times like winter, a plant has to stop growth, conserving its energy and making it more useful at a better time like spring. (Give me best answer :))
