What 3 things are required for germination?
Water, sunlight, warm temperatures
How does the sun play a role in the life of a plant?
Leaves absorb sunlight, photosynthesis, make food
The part of the tree that is counted to determine the age of the tree
Annual ring
Process by which green plants, using chlorophyll and the energy of sunlight, produce carbohydrates from water and carbon dioxide, release oxygen.
Photosynthesis
In the leaf what is glucose converted to?
Cellulose
Large primary descending root with, many secondary roots branching from the primary root
Tap root
What provides support to herbaceous stems?
Turgor
When two trees are grown together as one.
Grafting
The portion of a stem or other structure between two nodes.
Internode
How do simple leaves differ from compound leaves?
Compound: The leaf is separated into distinct leaflets, each with its own small petiole
Simple: The leaf may be lobed or divided, but does not form distinct leaflets.
No visible primary root, clumps of very thin roots, usually shallow in the soil
Fibrous Root
What are the three main functions of the leaf?
Photosynthesis, Gas exchange, transpiration
Two major environmental influences that effect the growth rate of stems?
Rainfall
Natural Disasters
The stem of any leaf
Petiole
How are leaves used to distinguish between different plants?
No leaves are the same and you look at the margins, shapes, tips, and base.
The three main types of roots and one way to describe them.
Storage - stores Carbs
Taproot - one primary root, deep descending
Fibrous - many clumps of roots, shallow in soil
The two vascular system parts in a plant.
Xylem and Phloem
The number of trees in the United States
228 Billion
The cellular layer of an organism; the outer skin.
Epidermis
Label the parts of the leaf.
Draw on board
List the three functions of the root.
1. Anchor the plant,
2. Absorb water and dissolved minerals
3.Store food
The part of the cell that provides support to woody stems.
Rigid stem walls
Study and matching of tree rings with the objective of dating events in the recent past.
Dendrochronology
The fluid-conducting tissues of a plant including both xylem (water conducting) and phloem (food-conducting) tissues
Vascular Tissue
Name and draw two examples of different leaf margins.
