Life Cycles & Seeds
What is an annual?
A plant, like corn or a petunia, that completes its entire life cycle in just one growing season.
What is water?
In order for a plant to produce its own food through photosynthesis, it needs light, chlorophyll, carbon dioxide, and this liquid.
What are sepals?
These form the outer covering of a flower bud and protect the inner parts before the flower blooms.
What is a biennial?
A plant, like a blackberry bush, that requires exactly two growing seasons to produce seed.
What is respiration?
This is the process where a plant breaks down its stored food (carbohydrates) in the presence of oxygen to release energy.
What are the anther and the filament?
The stamen, which is the male reproductive part of the flower, is made up of these two specific structures.
What is germination?
This process is defined as an embryo "waking up" and changing into a seedling.
What is wilting? (or "What is a wilt?")
This physical reaction occurs when a plant transpires (sweats) more water than it is able to take in through its roots.
What is the stigma?
This sticky opening at the top of the female reproductive organ is perfectly designed to catch and hold onto pollen.
What is the correct temperature?
Moisture, air, and this specific condition are the three primary things an embryo needs to begin germination.
What is glucose?
During photosynthesis, a plant takes in water and carbon dioxide, and produces oxygen along with this specific type of food sugar.
What is the ovary?
The actual site of fertilization, this enlarged portion at the base of the pistil produces ovules that eventually develop into seeds.
