Tree Processes
What is water?
During fall, deciduous trees do this with their leaves.
What is drop them?
These cells carry food and sugars made in the leaves downward and to other parts of the tree.
What are phloem?
Maple and oak trees are considered this type, since they drop their leaves in the fall.
What is deciduous?
This tree is known for having bark that takes on the appearance of being striped.
What is the striped maple?
The food for a tree is made in its leaves and carried by the phloem to the rest of the tree. The food is in the form of these.
What are sugars?
Deciduous tress drop their leaves to prevent this.
What is water loss?
This thin layer of growth cells just inside the bark is invisible to the naked eye.
What is cambium?
The process by which leaves use water, chlorophyll, carbon dioxide and energy from sunlight to make sugars and starches is called this.
What is photosynthesis?
The top of the leaves of this tree are light green, while the underside features a distinct silvery-white coating that flashes in the wind.
What is the silver maple?
This process begins with the cambium producing new cells
What is growth?
Due to frozen ground, this is often unavailable to trees in winter.
What is water?
These older, dead xylem cells help support the tree.
What is the heartwood?
This is the process by which trees release water through their leaves.
What is transpiration?
The leaf of this tree features 5 distinct lobes separated by smooth, U-shaped spaces (sinuses). The edges are mostly smooth with a few large, pointed tips. This iconic leaf is famous for its vibrant yellow, orange, and fiery red autumn foliage, and it's use on the Canadian flag.
What is the sugar maple?
Older xylem becomes this.
What is heartwood?
What are conifers or evergreen trees?
Another name for the new xylem cells is this.
What is sapwood?
This substance often found in the leaves helps plants capture sunlight for photosynthesis.
What is chlorophyll?
Unlike the sugar maple, its margins are finely serrated (toothed). The leaf stem is usually noticeably red even in summer.
What is the red maple?
Each year of growth of the tree is recorded by these.
What are its annual rings?
Needles of evergreen trees have a waxy coating and this, which help prevent water loss.
What is a small surface area?
These cells carry water and minerals upward from the roots.
What are xylem?
Both transpiration and photosynthesis occur in this part of the tree.
What are its leaves?
This tree is known for strong roots and a flower called Mayflowers. We have not seen one yet here.
What is the Hawthorn tree?
