DJ Venditti – Scavenger Hunt Collection Terms: Actin- globular protein found in eukaryotic cells. Actin is the monomeric subunit of two types of filaments in cells: microfilaments, one of the three major components of the cytoskeleton, and thin filaments, part of the contractile apparatus in muscle cells. Actin participates in many important cellular processes including muscle contraction, cell motility, cell division and cytokinesis, vesicle and organelle movement, cell signaling, and the establishment and maintenance of cell junctions and cell shape.
Angiosperm-A plant that has flowers and produces seeds enclosed within a carpel. The angiosperms are a large group and include herbaceous plants, shrubs, grasses, and most trees. Angiosperms are the most diverse group of land plants. Replaced conifers as the dominant trees around 60-100 million years ago.
Bryophyte- are members of the land plants that are non-vascular and food-conducting strands in their roots (xylem and phloem), or that they are poorly developed. They do not have roots, only filamentous rhizoids.
Cellulose- An insoluble substance that is the main constituent of plant cell walls and of vegetable fibers such as cotton. It is a polysaccharide consisting of chains of glucose monomers. Cellulose makes plant stems, stalks and trunks rigid and gives structure to cell walls. Endosperm- The part of a seed that acts as a food store for the developing plant embryo, usually containing starch with protein and other nutrients. Endosperm is the tissue produced in the seeds of most flowering plants around the time of fertilization. It surrounds the embryo and provides nutrition in the form of starch, though it can also contain oils and protein.
Gibberellins-plant hormones that regulate growth and influence various developmental precesses, including stem elongation, germination, dormancy, flowering, and sex expression. Gibberellins are involved in the natural process of breaking dormancy and various other aspects of germination.
Lignin- A complex organic polymer deposited in the cell walls of many plants, making them rigid and woody. The primary constituent of wood other than carbohydrates; binds to cellulose fibers to harden and strengthen cell walls of plants
Meristem- A region of plant tissue, found chiefly at the growing tips of roots and shoots and in the cambium, consisting of actively dividing cells forming new tissue. The meristematic cells give rise to various organs of the plant, and keep the plant growing. The Shoot Apical Meristem (SAM) gives rise to organs like the leaves and flowers.
Phloem- The vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves. The living tissue that carries organic nutrients, particularly sucrose to all parts of the plant where needed. The phloem is concerned mainly with the transport of soluble organic material made during photosynthesis.
Water Potential- the potential energy of water per unit volume relative to pure water in reference conditions. Water potential quantifies the tendency of water to move from one area to another due to osmosis, gravity, mechanical pressure, or matrix effects such as surface tension. Water potential has proved especially useful in understanding water movement within plants, animals, and soil. Water potential is typically expressed in potential energy per unit volume and very often is represented by the Greek letter Ψ.
Conifer Leaf: small needle like projections that grow on most conifer trees, or gymnosperms. leaf produced by a conifer plant. Exist year round on the tree Autotroph-An organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide. Organism that synthesizes its own food.
Deciduous Leaf- Deciduous means "falling off at maturity". Decidous leafs occur on trees and shrubs and have seasonal shedding. When photosynthesis is near imposible such as in the wintertime, deciduous plants shed their leaves to conserve energy for the plant. Thorn of a plant- Hard, pointed structure used by plants as a defense from predators.
Stem, woody:helps accommodate plant growth and to increase plant circulation. Outter layer may be covered with a corky bark Fruit fleshy with seed-As the ovules develop into seeds, the ovary begins to ripen and the ovary wall, the pericarp, may become fleshy (as in berries) Fruit dry with seed-As the ovules develop into seeds, the ovary begins to ripen and the ovary wall, the pericarp, may form a hard outer covering (as in nuts)
Modified Stem of a Plant- Potatoes show stems coming out from many sides. Not all plants have 1 stem.Cuticle Layer of a Plant: Produced by the epidermis and covers the epidermis. It’s a waxy coating on the very outside of leaves and stems. Cutin is an important component of the cuticle. This important adaption helps prevent water loss through evaporation. Pollen-A fine powdery substance, typically yellow, consisting of microscopic grains released from the male part of a flower. Each grain contains a male gamete that can fertilize the female ovule. Pollen is transported by the wind, insects, or other animals
