Plant Unit Part 1

First 12

Botany the study of plants
Botanist a scientist who studies and classifies plants
trait a physical characteristic or behavior that distinguishes one type of organism from another
plants organisms that do not move from location to location and have the ability to make their own food through the process of photosynthesis
producers organisms that make their own food (plants)
consumer organisms that must eat other organisms for their nourishment
mosses (bryophytes) non-vascular plants that grow low to the ground and reproduce with spores
fern(pteridophytes) a seedless vascular plant with roots, stems, and leaves (reproduce w/ spores)
gymnosperm (conifer) a vascular plant whose seeds are not enclosed (they're "naked".) (Seeds form on -female- cones.) (Most are "evergreens")
angiosperm flower bearing plants which produce seeds totally enclosed within a fruit
Mosses, Ferns, Conifers, Flowering plants four groups for classifying plants
spore an asexual reproductie cell with a hard covering (NOTE: spores are produced on mature stalks formed by the fertilization of female egg cells by male sperm cells on the same plant)
seed a mature, fertilized plant ovary made up of a seed coat, one of two cotyledon, and an embryo
leaves the part of the plant in which food is made (may be simple of compound)
chlorophyll a green pigment inside some plant cells which traps the energy of the sun and uses it to produce food for the plant
photosynthesis the process by which plants use water, carbon dioxide, chlorophyll in their leaves, and light energy from the sun to produce their own food (in the form of glucose) and give it off oxygen as waste
root an organ that anchors a plant in the ground and absorbs water and minerals from the soil
stem the part of the plant that supports the leaves and contains the "pipes" or vascular bundles that transport water, food, etc. throughout the plant
non-vascular plants (bryophytes) plants which lack the "pipes" which carry water and nutrients to all parts of the plant (these plants are low to the ground- mosses and liverworts)
vascular tissue plant tissue made up of tubelike cells that carry food, water, and minerals from one part of the plant to another.
xylem vascular tissue that conducts water from the root to the stem and leaves
phloem vascular tissue that conducts food from the leaves to the rest of the plant
cotyledon a food-storing part of a seed that is used by a developing plant until it can produce its own food
monocot an angiosperm with one cotyledon (tulips, most grasses)
dicot an angiosperm with two cotyledon (beans, peanuts)
pollination the transfer of pollen from the male part of a flower to the ovary of a female pistil
pollen the male sex cell of a plant
ovary the female sex cell of a plant
germination the development of a plant embryo into a young plant
embryo a developing, many celled organism
vegetative propagation the starting of new plants by rooting mature plant parts (leaves, roots, cuttings, etc.) in water or soil (spider plant!!!)
