Characteristics of
Angiosperms
Angiosperms
True or False.
Angiosperms cannot survive in as many habitats as gymnosperms.
False.
List the four challenges of terrestrial life plants faced.
Plants' challenges of terrestrial life include: maintaining water, obtaining resources, support, and reproduction and dispersal of offspring.
What are the ploidy of a haploid and a diploid?
Haploid: n
Diploid: 2n
What are the functions of roots?
The four functions of roots include: absorption, anchoring, storage, and vegetative reproduction and competition.
True or False
Eudicots only have a single cotyledons.
False.
What are the two groups of angiosperms known as?
Monocots and eudicots.
How do plants obtain their resources?
Roots, stems and leaves are used in order to obtain resources.
What structures are produced by the gametophyte generation? What is this structures ploidy?
Gametes (n)
What are some examples of plants with fibrous roots?
Leeks, corn and grasses are all examples of plants with fibrous roots.
Are scattered vascular bundles a characteristic found in monocots or eudicots?
Monocots.
Blank ensures pollination & protect developing embryo.
Flowers
What type of two types of vascular tissues are found in plants?
What are each responsible for transporting?
Xylem is responsible for transporting water and minerals, while the phloem is responsible for transporting sugars.
What process are haploid spores created from diploid sporophytes?
Meiosis
Why are adventitious roots considered to be not true roots?
They are not true roots because they can form from other parts of the plant.
Threes or multiples of threes.
What are the characteristics of a complete flower?
Sepals, Petals, Pistils and Stamens.
What are cell walls thickened and reinforced with in order to support the plant?
Cell walls are reinforced with lignin.
Are bryophytes sporophyte or gametophyte dominant?
Gametophyte dominant
What is an advantage of tap roots?
Tape roots can penetrate deeper in the soil than fibrous roots, therefore they can access water and minerals that are deeper underground.
Describe the type of roots eudicots are known to have.
Eudicots are known for having long taproots as their root system.
How do you distinguish a perfect flower from a imperfect flower?
A perfect flower include male and female structures.
An imperfect flower include either or, but never both.
How do plants maintain their needs for water?
Plants maintain their moisture balance with their waxy cuticle, use of their stomata and guard cells, and also adapting different shapes and structures.
What are the two haploid reproductive structures at the top of the gametophyte generation?
Male: Antheridia
Female: Archegonia
Mangroves have roots that extend up from the soil. These are known as what type of root?
Pneumatophores
List the characteristics of both monocots and eudicots.
Monocots: One cotyledon, veins are usually parallel, flower parts in usually in a multiple of three, and vascular bundles are scattered.
Eudicots: TWO cotyledons, veins are netlike, flower parts are usually in four or fives, and vascular bundles in the stem are in a ring formation.
