Lesson 15 Terms Flashcards
Angiosperms
flowering plants that produce seeds in fruit
Antheridia
produce sperm
Archegonia
produce ovum
Botany
study of plants
Conifers
Cone-bearing plants
Cotyledon
first leaf or first pair of leaves produced by the embryo of a seed plant
Dicots
two cotyledons
ferns
seedless vascular plants; reproduce using spores
Flowering plants
This group consists of true vascular plants that produce flowers and pollen. Their seeds are protected by fruits and nuts.
fronds
leaves of ferns
Gametophyte
the first generation that occurs when a haploid spore is produced by meiosis
Gymnosperms
seed plant that bears its seeds directly on the surfaces of cones
Leaflets
part of the fern structure; arranged on either side of the petiole
Leafy shoot
a tiny stem with very tiny leaf-like structures which absorb nutrients and water from the environment and perform photosynthesis
Life cycle
alternation of generations
monocots
one cotyledon
Mosses
Mosses
individual plants packed tightly together; reproduce using spores
Non-seed-bearing plants
reproduce using spores
Non-vascular
he plant lacks vascular tissue and is therefore often much smaller and has a simpler cell structure
Petiole
a blade attached to a fern leaf
Phylum Anthophyta
angiosperms (flowering plants)
Phylum Bryophyta
mosses
conifers
Phylum Coniferophyta
Phylum Pterophyta
ferns
Pollen cones
male reproductive organs; male cones
Prothallus
fern gametophyte
Rhizoid
a root like structure; grows into the food source and consume the food via external digestion
Rhizomes
fronds grow from stems growing underground or attached to a tree
Seed
an embryo of a plant with diploid cells surrounded by a food source with a protective covering
Seed-bearing
reproduce using seeds
Seed cones
female reproductive organs of a conifer; female cones
Sori
clumps of sporangia that produce haploid spores
Spore
tiny, one-celled reproductive structures
Sporophyte generation
begins after fertilization. The zygote grows out of the female gametophyte into a stalk with a capsule on top, in which more spores are created.
