Autotroph
provide / make their own food for energy through photosynthesis
Stimulus
a change in the environment that makes a living thing react; e.g. light, gravity, touch, water, temperature
Response
the reaction to a stimulus
Reproduction / Reproduce
the ability of an organism to produce more organisms / offspring of the same kind
Asexual reproduction
the kind of reproduction from a part of a single living thing (needing one parent part)
Sexual reproduction
the kind of reproduction that results from the union of an egg and a sperm (needing two parents)
Egg
a female reproductive cell; contained in the ovule of the flower
Sperm
a male reproductive cell; contained in pollen of the flower
Growth
process whereby the organism becomes larger
Development
process that results in the organism becoming more complex
Taxonomy
a system of categorizing organisms based on shared observable characteristics
Kingdom
the broadest level of classification / taxonomy; the 5-kingdom system is widely accepted
Genus
a classification of closely related organisms
Phylum (pl. phyla)
the first further classification of a kingdom; sometimes referred to as divisions in the plant kingdom
Species
the smallest classification group; all organisms can produce offspring the same kind
Scientific name
the name of a organism made up of its genus and species
Nonvascular plants
plants without vessels to carry water, minerals, and food
Vascular plants
plants with tube-like vessels that carry water, minerals, and food throughout the plant

xylem - transports water and minerals from roots to the rest of the plant

phloem - transports food from the leaves to the rest of the plant
Seed-producing plant
plants that reproduce through seeds; may be cone-bearing or flowering plants
Seed
Plant part that contains the embryo (the beginnings of roots, stem,leaves), stored food (cotyledons) and seed coat from which a new plant grows
Spore-producing plants
plants that reproduce through spores, such as ferns and mosses
Spore
a single cell that grows into a new plant; the tiny reproductive cells in mosses and ferns
Cone-bearing plants
trees or shrubs that produce seeds in cones; most are evergreen plants
Flowering-plants
the variety of plants that grow seeds inside flowers; the flower may become a fruit
Monocot
the plant seed has one food part; the plant has identifying structures
Dicot
the plant seed has two food parts; the plant has identifying structures
Thorn
sharp outgrowths from the plant stem that help defend the plant
Thigmotropism
the response by leaves to close when touched
Plant poison
chemical substances designed to discourage animals from eating them
Leaf / Leaves
the part of the plant that collects sunlight and makes food
Stem
the part of the plant that supports the plant, stores food, allows for movement of materials through vessels
Root
the part of the plant that anchors the plant in the soil, absorbs water and minerals, stores food
Root hairs
extensions along the roots that increase the root surface area
Flower
part of a seed-producing plant that produces seeds
Petals
the kind of brightly colored leaves inside the sepals that surround the reproductive organs, protecting and providing a place for visiting insects
Stamen
the male part of a plant
Anther
the thick part on top of the stamen where pollen grains form
Pollen
the small, male reproductive body of a flowering, seed plant that contains the sperm (male reproductive cells)
Filament
the slender stalk part of the stamen
Pistil
the female reproductive organ in a plant
Stigma
the part of the flower on which a pollen grain must stick in order for fertilization to take place; part of the pistil (top part) where pollen lands
Style
stalk-like part of the pistil (middle part) that connects the stigma and ovary
Ovary
contains the eggs in the plant's female reproductive organs; the part of the flower in which eggs develop
Ovule
the part of the ovary that develops into a seed after fertilization
Pollination
the process by which of pollen grains transfer from the stamen to the stigma
Fertilization
when pollen from the stamen enters the ovule in the ovary of the flower
