Ch 12 Flashcards
Contrast spreading branching inspire like branching
Spreading branching consists of the trunk separating close to the ground creating many limbs in different angles
Spire like branching is when one trunk goes all the way up and has limbs branch off of that
What characterizes a deciduous tree?
They lose their leaves in the fall and stay bare all winter
Which gymnosperm looks like a palm tree?
Cycads
How did the different structures of male and female conifer cons show God’s design?
Male and female cones are needed to reproduce. God showed his design in that the mail cone’s pollen will blow in the wind and get into the prickly cone to fertilize the egg in the cone. It is a super design!!
Did ginkgo trees produce fruit? Why or why not?
No. A fruit is the ripened ovary of a flower; ginkgos are gymnosperms and do not produce flowers or fruits.
Contrast taproots with spreading roots
Taproot go straight down and are thick with smaller roots coming out of the sides
Spreading ribs are fairly equal in size and spread out to sometimes three times the diameter of the canopy. They anchor the tree.
List the three main functions of tree roots
Absorb water and minerals
anchor the tree firmly in the soil
store food
List and define the four major types of adventitious roots
Roots that grow from the stem, branches, leaves, or mature would be roots.
Buttress roots, common in large tropical trees and occur at the trees base. Look like large walls or plank like extensions providing support to the stem.
Stilt roots and prop roots are similar to buttress roots. Stilt roots grow down from branches into the soil.
Prop roots grow out from the trunk then down into the soil.
Aerial roots are entirely above ground and Mac to stabilize the tree.
Where is a trees xylem tissue located?
It is located in the wood
Define competition as it relates to trees
The struggle against other plants and trees for space sunlight water and minerals needed to grow
Which type of bud forms new branches on the stem?
Lateral bud
Which leaves are usually found at the tops of trees?
Sun leaves
Describe the life of the tree in page 121.
The tree is 22 years old.
The first five years were abundant with a good environmental conditions and the tree grew quite a lot.
In the sixth and seventh years there was stress on the tree
In the seventh year a fire occurred.
The next 4 to 5 years show good gross with a little competition.
The last 10 rings show that the tree had to compete with new trees growing around it because the rings are quite small in width.
Define forest
A dense collection of trees with a thick top layer of interlaced leaves called the canopy
Why do trees not grow well beyond the tree line?
The winters are too long and cold and harsh and the summers are too short for good growth to happen
