Seed Germination
What percent of seeds sprout?
75%
What is photosynthesis?
The process of green plants creating their food that combines carbon dioxide and water, in the presence of light to make sugar and oxygen for the plant to use.
What is plant propagation?
Plant propagation is the process of creating new plants from existing ones.
Which colors have the greatest impact on plant growth?
Red and Blue
Dormant
A plant that is not active but has the ability to become active
What affects the rate that seeds sprout?
Temperature, Moisture, and seed viability.
The process of plants taking water and air through their roots is known as what?
Absorption.
How many forms of plant propagation have we discussed?
Two
Which light causes elongated and soft growth?
Red light
Cotyledon
An embryonic leaf in seed bearing plants, one or more of which are the first leaves to appear from a germinating seed.
What are the 3 main parts of a seed?
The three main parts of a seed are the embryo, endosperm, and seed coat.
What is respiration?
Respiration is the process through which plant leaves, stems and roots consume oxygen and give off carbon dioxide.
What has to happen for seeds to be produced during sexual propagation?
Fertilization
What is Daily Light Integral (DLI)?
DLI is how much light a plant has received throughout the day.
Seed coat
What factors in to seed germination?
Water, Oxygen, Temperature, and Sunlight.
Transpiration
Transpiration is the process by which plants lose water from leaves and stems.
During sexual propagation, where is the pollen transferred to?
The stigma
The response of plant growth based upon the number of hours of light received each day is known as what?
Photoperiodism
A human, animal, or plant in the early stages of development is known as what?
The embryo
How many leaves do Monocots produce?
Monocots produce one leaf.
The process by which food and nutrients are moved within a plant from one plant part to another is known as what?
Translocation.
Which process of reproduction results in offspring that is genetically identical to the parent plant?
Asexual
Why do plants have a specific wavelength?
They contain pigments like chlorophyll which absorbs specific wavelengths of light for photosynthesis, causing a green appearance in the plants
Endosperm
Tissue formed within a seed that contains energy and protein for the germinating seed.
