Rings in a tree trunk formed by the growth of wood in layers.
What are Annual Growth Rings?
Each year the tree adds one ring; wide bands between rings indicat much rain while narrow bands mean drought.
Reproduction that involves one parent and no egg or sperm.
What is Asexual Reproduction?
Ex. creating a new plant with a rooted cutting or grafting.
The process in which cells break down food to release energy.
What is Cellular Respiration?
A process of both plants and animals. A special low temperature burning that breaks down glucose in plants & animals.
The green pigment in plants that captures light energy for photosynthesis.
What is Chlorophyll?
Chemical compound made by chloroplasts/ plant organelles.
A seed that starts to grow into a new plant when given the right temperature & light.
What is Germinate?
Seeds begin to grow a new plant when this happens. Requires a roughed up seed coat, a plant embryo & food for new plant
A cell that opens and closes stomata in plants.
What is a Guard Cell?
These cells open and close by taking up water and swelling opening up the stoma.
A see liquid that many kinds of Flowers Produce/
What is Nectar. (144(
Insect searches for nectar cause the cross pollination
of plants from pollen that falls off- bees when they gather nectar in flowers.

The lower part of the pistil which contains eggs.
What is the Ovary? (144)
The female reproductive part on a plant flower.
The stalk that attached to the leaf under the stem.
What is a Petiole. (136)
leaf stalk providing structure and nutrients to leaf.
The vascular tissue in plants that carries food from leaves to other parts of plant.
What is Phloem? (135)
forms tubes carrying nutrients to stems & roots.
The process by which plants make their food.
What is photo synthesis?
Cargon dioxide + water + light energy (makes) sugar + oxygen.
A chemical that absorbs certain types of light.
What is Pigment?
A chemical necessary for photosynthesis in plants.
The female part of a flower which contains the ovary.
What is the Pistil? (144)
Female plant part consisting of stigma (top) , style (middle) and ovary (bottom)
The tiny structures of seed plants that contain sperm.
What is Pollen? (144)
yellow sperm carried by bees,birds,other insects, & wind from stamen to pistil.
The process by which pollen is transferred from the stamen to the pistil.
What is Pollination? (144)
How sperm gets to eggs in plant fertilization.
Reproduction that involves two parents, an egg and sperm.
What is Sexual Reproduction?
This process in Gymnosperms requires cones, male & female.Pollen grains grow tubes that reach eggs in the ovary of the Pistil.
The male organs of reproduction in flowers.
What is the Stamen? (144)
The male sex organ of the flower is made of the anther (top) and filament (bottom)
A small opening in a leaf that allows gases to enter and leave; plural is stomata.
What is the Stoma? (136)
This opening allows carbon dioxide and oxygen to enter and leave the leaf; also water vapor exits here.
The vascular tissue in plants that carries water and minerals from roots to stems and leaves.
What is the Xylem? (135)
This vascular tissue helps the leaf moving water and minerals from root to leaf
The resulting fertilized cell after egg and sperm unite.
What is a Zygote? (143)
The beginning of a new plant.
