|
Definition
| the sperm cell and the egg cell |
|
|
Term

Term
| How do animals help to pollinate flowers? |
|
Definition
| A sugary food called nectar, is located inside of a flower. When a animal enters a flowers to drink/eat nectar, the pollen sticks to the pollinator and when the animal sucks another flower's nectar, the pollen from the other flower sticks to the stigmas of the other flower. |

Definition
| a monocot's petals are in groups of threes, the veins of its leaves are parallel, it has one cotyledon, and many scattered roots. |
|
|
Term
| where does the embryo in a seed get food? |
|
Definition
| The cotyledon or seed leaf. |
|
|
Term
| A plant has 12 petals. Is it possible to tell that the plant is a monocot or dicot with only this information? Why? |
|
Definition
| 12 is a common factor of 3 and 4, it could be a monocot or a dicot. You would have to use another part of the plant. |

Definition
|
|
Term
| Describe the process of embryo formation in an angiosperm. |
|
Definition
| When pollen sticks to a stigma the pollen goes through the pollen tube and drills a hole into the ovule and then the sperm cell and egg cell combine and an embryo forms in the seed. |

Term
| What do the xylem and phloem do? |
|
Definition
| The xylem brings water up and the phloem sugar down |
|
|
Term
| What is the main difference between Gymnosperms and Angiosperms? |
|
Definition
| Angiosperms have flowers and fruit. Gymnosperms have naked seeds. |
|
|
Term
|
Definition
| Leaf cells that convert stuff into sugar. |

Term
|
Definition
| pigment that absorbs sunlight (green) |
|
|
Term
| What is the chemical formula for photosynthesis? |
|
Definition
| Water+Carbon dioxide+sunlight= sugar & oxygen |
|
|
Term
| What is water dispersal and why is it important? |
|
Definition
| Water dispersal is how seeds move from one place to another through water. If seeds drop to the ground directly under the parent plant they will not have the room and nutrients they will need to grow. |
|
|
Term
| What is wind dispersal and why is it important? |
|
Definition
| Wind dispersal is when seeds and/or small fruits are carried by the wind. When they land they plant themselves, maybe colonizing mountains at a time. Hundreds of plants use this method. Most plans considered to be weeds disperse their seeds through wind. |
|
|
Term
| What is pollination and why is it important? |
|
Definition
| A pollinator takes the pollen from a stamen on a male flower and lands on a female flower. Then, the pollen goes down the pistil to the ovary, and fertilizes the eggs. Pollination leads to the creation of new seeds. FERTILIZES the flower so the seed can be produced. (sperm and egg mix DNA.) |
|
|
Term
| What is self pollination? |
|
Definition
| A flower uses its own pollen and ovules to make a new seed. |
|
|
Term
| What is cross pollination? |
|
Definition
| Two flowers of the SAME SPECIES exchange pollen to the other flower by pollinators. |
|
|
Term
| What does a plant need to grow? |
|
Definition
| Sunlight, carbon dioxide, water and room to grow. |
|
|
Term
| How to propagate a plant with roots? |
|
Definition
| Choose the plants you wish to grow from a cutting. Using sharp garden secateurs (pruners), snip off shoots from the plant. Strip a half to two thirds of leaves from the lower part of the cutting and remove flower buds because they will suck the nutrition out that the plant needs during the time it is growing new roots. Treat the cutting. Start your cutting in sand, soil, or even just water. Keep the cutting moist, but not over watered (try a mister). Transplant your cuttings to their final growing spot. |
