What is Life?
What is abiogenesis?
The idea that all of life came from nothing.
What are the parts of the vascular system?
Xylem, phloem, vascular cambium.
Found in the roots, stems, and leaves.
What are the main functions of roots?
Support the plant in the soil.
Absorb and transport water and nutrients throughout the plant.
What is a coleoptile?
A sheath that surrounds the new leaf of a monocot seedling.

Who are the two scientists who helped prove spontaneous generation wrong?
Francesco Redi and Louis Pasteur
Name two kinds of specialized stems.
Tubers
Corms
Rhizomes
Stolons
What are the ingredients used in photosynthesis? What are the things produced?
Sunlight, water, CO2 are ingredients.
Glucose (plant sugar) and oxygen are produced.
What are root hairs?
Tiny tubes on larger roots that collect water for the plant.
What is the main function of a flower?
Reproduction
What are the six characterisitics of living things?
Eat
Breathe (Respirate)
Move
Reproduce
Have cells
Grow
What are the reproductive parts of a flower?
Stamen, with anthers.
Pistil, with ovules and ovaries.
What is pollination?
When pollen from an anther is transfered to a pistil, the ovules are fertilized and will become seeds.
What are adventitious roots?
Roots that grow from any non-root tissue.
What part of a dicot seed is stored food for the plant?
Cotyledons
What is the theory of spontaneous generation? Give an example.
The theory that living things can be created out of nothing.
Example: maggots forming on meat, (instead of coming from other living things)
What is an angiosperm?
Flowering plant
What part of a monocot seed is stored food for the plant?
Endosperm
What is vegetative propagation?
Reproducing a plant using a part other than a seed.
What are the four main groups of Phyla in the plant kingdom?
Non-vascular plants
Vascular plants that reproduce using spores
Vascular plants that reproduce using seeds from cones.
Vascular plants that reproduce using seeds from flowers/fruit.
Who developed the system of binomial nomenclature?
Carl Linnaeus
What is the most important function of a leaf?
Photosynthesis, making food for the plant.
Name two ways monocots and dicots are different.
Monocots have one cotyledon, dicots have two.
Monocots have leaves with parallel venation; dicots have leaves with palmate or pinnate venation.
How can you tell something is a plant? (How would you know it isn't a fungus?)
It photosynthesizes.
What is a gymnosperm?
A vascular plant that reproduces using cones.
