Stoma
Where gas exchange takes place in plants
Phloem
Vascular tissue consisting of living cells that distribute sugars throughout the plant
Xylem
Vascular tissue made of dead cells that transport water and minerals from the roots
Nonvascular Bryophyta
Mosses are included in a group of plants called
Ferns
They are seedless vascular plants with well developed roots and rigid stems. Many species have leaves called fronds and are most diverse in the tropics.
Conifers and angiosperms
The dominant types of seed plants
Vascular tissue, Cuticle, Stomata, Seeds and pollen.
What are the adaptations that help plants live on land?
Charophyceans, Bryophytes, Seedless Vascular Plants, Gymnosperms, Angiosperms
These represent the most likely sequence of the evolution of plants.
Alternation of Generations
Life cycle seen in plants
Diploid sporophytes that produce spores by meiosis alternate with gametophytes that produce gametes by mitosis.
Describes the alternation of generations in the plant life cycle.
Gametophyte Generation
The dominant stage of mosses
Both have flagellated sperm and have sporophytes that produce haploid spores.
Ferns and mosses are similar due to what?
Gametophyte, Sporophyte
In a moss, most of the plants that we see are _______, and in a fern the most dominant stage is the ______.
Fern
What has a dominant sporophyte generation and a free living gametophyte generation?
Coniferous Period
The great depositions of organic material during the Carboniferous period led to what?
Male Gametophyte
Which part of the life cycle does a pollen grain represent?
Gymnosperms
What plants have a dominant sporophyte generation and a seed but no fruit?
Tree, Cone
The _____ represents the sporophyte generation of a conifer and the ______ produces gametophytes.
Pollen Grain
Male gametophyte of a conifer.
Pollen Tube
The stigma is the protective chamber where the _______ develops.
Anther
Where the pollen grain develops.
Gametophye, Sporophytes
The angiosperm plant we see represents the _______ generation and the flower produces _______.
Fruit
The ripened ovary of a flower which is adapted to disperse seeds is called _______?
Fruit
What structure is found in angiosperms but not gymnosperms?
Spores
Angiosperms disperse their seeds by producing ______?
Angiosperms
Fruits, vegetables, corn, rice and wheat are all examples of what?
Petals
Plants dependent on nocturnal pollinators typically have flowers that have what adaptation?
Co-evolution
Plants and their pollinators evolve in response to each other's change in a process called _______?
Chloroplasts
What characteristic is shared by algae and seed plants?
