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.
