Actin-A globular protein that links into chains, two of which twist helically about eachother, forming microfilaments in muscle and other contractile elements in cells. The significance to plants is that it forms microfilaments for the plants structure and the contractile elements to defend and protect the plants.
Angiosperm-A flowering plant, which forms seeds inside a protective chamber called the ovary. The significance to plants is specific type of flowering plants. It shows the difference of flowering plants and their seeds to other plants.Autotroph-An organism that obtains organic food molecules without eating other organisms or substances derived from other organisms. They use energy from the sun or from the oxidation of inorganic substances to make organic molecules from inorganic ones. The significance of the autotroph to plants is that most plants are autotroph and do make their own food and energy.
Cellulose-Organic polysaccharide compound, found in a linear chain of linked glucose units. It's the structural component of the primary cell wall.Cellulos has a significance to plants because it is a big part of their structure and keeping the plant from wilting but also from easy turgor.
Cuticle Layer of a Plant- A waxy covering on the surface of stems and leaves that acts as an adaptation to prevent desiccation in terrestrial plants. The cuticle layer is significant to plants because it keeps water in the plant so the plant can survive.
Endosperm-A nutrient rich tissue formed by the union of a sperm cell with two polar nuclei during double fertilization, which provides nourishment to the developing embryo in angiosperm seeds. The endosperm is significant to plants because it is important during fertilization of angiosperm seeds and the development of the plant.
Ethylene- The only gaseous plant hormone. Its effects are response to mechanical stress, programmed cell death, leaf abscission and fruit ripening. Ethylene is significant to plants because it keeps the plant from dying. The hormone keeps the cells through the cycle and is used when the plant is effected by its environment.
Gibberellins- A class of relate plant hormones that stimulate growth in the stem and leaves, trigger the germination of seeds and breaking of bud dormancy, and stimulate fruit development with auxin. The gibberellins significance to plants is shown in growth of the plant because the hormone regulates the growth and the development of sees and fruit.
Lignin- A hard material embedded in the cellulose matrix of vascular plant cell walls that functions an an important adaptation for support in terrestrial species. The lignin is significant in a plant because it helps with the structure of plants. It creates a harder cell wall that is more difficult for herbivores to eat.
Long Day Plant- A plant that flowers only when the light period is longer than a critical length. The significance of a long day plant is to show an adaptation because the plant needs more sun so it grows when the days are longer, the spring and summer.
Phloem- Vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant. The phloem is significant to plants because it keeps nutrients flowing throughout the plant through the tubes. The phloem is critical for a plant.
Short Day Plant- A plant that flowers only when the light period is shorter than a critical length. The short day plant shows significance to plants because its an adaptation to the shorter days with less light. The plant has adapted to the winters and falls shorter light periods.
Vascular Plant Tissue- Plant tissue consisting of cells joined into tubes that transport water and nutrients throughout the plant body. The vascular plant tissue is significant to plants because it transports necessary nutrients and water to the plant body.
Xylem- Vascular plant tissue consisting of mainly tubular dead cells that conduct most of the water and minerals upward from roots to the rest of the plant. The xylem is significant to plants because it reaches from the roots of the plant to carry the water upwards to other parts of the plant. It keeps water flowing instead of all the water going to the roots from gravity.
Thorn of a Plant- A modification of an axillary shoot system where the leaves are reduced and the stems have thorns for protections against herbivores. Thorns are significant to plants as a defense. Other organisms have defense mechanisms and for a plant the thorn is its defense mechanism.
Stem-Woody- A stem that has been growing for 2+years. The stem has thickened to accomadate the growth and circulation in the plant. The woody stem is significant to plants because it shows maturity. The woody stem shows that the stem is growing and becoming stronger for its plant.
Stem-Herbaceous- Stems that serve the same function as the leaves of the plant. They are modified stems with a leaf like texture and color. The significance of herbaceous stem plants are that they are used for medical uses and most are flowering plants.
Pollen- A coarse powder which contains the male gametes of seed plants. The pollen of a plant is significant because it is the way plants reproduce. The pollen has the male gametes to transfer to the female stigma to reproduce the plant.
Pollinator- The agent that moves the pollen from the male anthers of a flower to the female stigma of the flower to reach fertilization. The pollinator is significant to plants because it helps in the reproduction. The pollinator moves the pollen to plant to plant and makes it so the male and female gametes are crossed.
Frond- A larger divided leaf. The frond is significant to plants because it is the main cite of photosynthesis
