|
Explain how plants can grow.
|
They grow from the tips of stems, roots, and branches. They also get bigger in circumference.
|
|
|
What is Chlorophyll?
|
a green coloring in the chloroplasts that traps the light from the sun
|
|
|
What is a major source of the water vapor in the air?
|
transpiration
|
|
|
What are some characteristics of plants?
|
*are producers
*make food *are usually green *contain chlorophyll *usually don't move around |
|
|
What is the function(job) of the stem?
|
support the above ground parts...allow the movement of material between the roots and leaves...some store food...i.e. potatoes, sugar cane
|
|
|
What is the function(job) of a root?
|
water and minerals enter through them...anchor the plant into the soil...some are food sources...i.e. carrots and beeets
|
|
|
What are Woody Stems?
|
Hard and rigid stems ie.- maple trees, pine trees.
|
|
|
What is a Cuticle?
|
A waxy coating covering the epidermis, protects the plant from drving out.
|
|
|
Name and describe the stem parts--Vascular tissue.
|
a. Xylem: tube-like vessels that transport water and minerals up from the roots through the stem to the leaves...is dead..."what we call wood"
b. Phloem- made of tube-like vessels that move food and water from the leaves to other parts of the plants...is alive. |
|
|
Name and describe the types of roots.
|
A. Fibrous...branched and spreading...can go very deep...i.e. African Violet
B. Tap Roots...thick...store food...i.e.carrots |
|
|
What are chloroplasts?
|
the part of the cell where photosynthesis thakes place.
|
|
|
What is respiration and where does it occur?
|
the process in which foods are broken down and energy is released...this occurs in the mitochondria.
|
|
|
What are plant leaves?
|
the organs for trapping sunlight and making food
|
|
|
What is photosynthesis?
|
the process in which plants use light to produce food...it changes water and carbon dioxide into sugar(glucose) and oxygen.
|
|
|
What are Palisade layers?
|
Where most of the food is made - long cells, below the upper eprermis.
|
|
|
What are Spongy layers?
|
It contains many air spaces and xylem and phloem (veins), loosly packed cells.
|
|
|
What does the Xylem do and where is it located?
|
carries water and mineral from the roots through the plant ...in veins of spungy layer
|
|
|
What are Herbaceous Stems?
|
Hard and rigid stems ie.- maple trees,pine trees.
|
|
|
What is the Palisade layer?
|
where most of the food is made...long cells below the upper epidermis
|
|
|
Define Stomate(stomata):
|
openings in the epidermis
|
|
|
What is transpiration and when does it usually occur?
|
the loss of water vapor through the stomata of a leaf....mostly during the day.
|
|
|
What are Anual Rings?
|
circular pattern inside a tree that reparesents one year of growth, made of xylem, also give clues to weather conditions.
|
|
|
What are the parts of a plant?
|
roots, stems, leaves
|
|
|
What is the Epidermis and where is it found?
|
Thin outer layer on top and bottom that protects the leaf.
|
