Studied by 1 person
Angiosperms
flowering plant; the seeds are borner within a fruit
Anther
in flowering plants, pollen- bearing portion of stamen
Carpel
ovule-bearing unit that is a part of a pistil
Club Mosses
type of seedless vascular plant that are also called ground pine because they appear to be miniature pine tree
Cone
Structure comprised of scales which bear sporangia; pollen- cones bear microsporangia and seed cones bear megasporangia.
Conifer
a group of trees and shrubs; Ex: pine trees and fir trees that grow in cooler areas of the world
Cuticle
Waxy layer covering the epidermis of plants that protects the plant against water loss and disease causing organisms
Cycad
type of gymnosperm with palmate leaves and massive cones; most often found in the tropics and sub tropics
Fern
A flowerless plant which has featert or leafy fronds and reproduces by spores released from the undersides of the frands.
Fruit
flowering plant structure consisting of one or more ripened ovaries that usually contain seed
Gametophyte
haploid generation of the alternation of generations life cycle of a plant; produces gametes that unite to form a diploid zygote.
Ginkgo
a genus of non-flowering seed plants, assigned to the gymnosperms
Gnetophyte
a small group of gymnosperms vascular plants that are represented by 3 living genera.
Gymnosperm
a group of seed-producing plants that includes conifers, ginkgo, and gnetophytes, characterized by seeds that are not enclosed in an ovary. They are often characterized by cones and needle-like leaves.
Horsetail
a leafless plant with hollow and rush like stems
Liverwort
small flowerless plants with leaf like lobes called a thallus, which looks like a lobed liver
Megaspore
one of the two types of spores produced by seed plants; develops into a megagametophyte (embryo sac).
Miscrospore
one of the two types of spores produced by seed plants; develops into a microgametophyte (pollen- grain).
Moss
type of bryophyte, a group consisting of non-vascular plants.
Non- Vascular Plant
bryophytes as mosses and liverworts that have no vascular tissue and either occur in moist locations or have special adaptations for living in dry locations.
Ovary
female gonad in animals that produces an egg and female sex hormones; in flowering plants, the enlarged ovule- bearing portion of the pistil which develops into a fruit.
Ovule
in seed plants, a structure that contains the megagametophyte and has the potential to develop into a seed.
Phloem
Vascular tissue that conducts organic solutes in plants; contains sieve-tube elements and companion cells.
Pistil
Reproductive flower structure composed of one or more carpels.
Pollen Grain
In seed plants, structure that is derived from a microscope and develops into a microgametophyte
Pollination
In gymnosperms, the transfer of pollen from pollen cone to seed cones; in angiosperms
Pollinator
Animal; e.g bee that inadvertently transfer pollen from another to stigma
Rhizoid
rootlike hair that anchors a plant and absorbs minerals and water from the soil
Rhizome
Rootlike, underground stem
Root
the underground organ that anchors the plant in the soil, absorbs water and minerals and stores the products of photosynthesis
Seed
mature ovule that contains an embryo with stored food enclosed in a protective coat
Sporangium
structure that produces spores
Sporophyte
diploid generation of the alternation of generations life cycle of a plant
Stamen
in flowering plants, the portion of the flower that consists of a filament and another containing pollen sacs where pollen is produced.
Stem
usually the upright,vertical portion of a plant, which transport substances to and from the leaves
Stigma
in flowering plants, portion of the pistil where pollen grains adhere and germinate before fertilization can occur
Style
elongated central portion of the pistil between the ovary and stigma
Vascular
Plant; type of plant that contains vascular tissue; e.g; ferns, gymnosperms and angiosperms
Xylem
vascular tissue that transports water and minerals solutes upward through the plant body; it contains vessel elements and tracheids.
