Lab 5, 6, 7 Flashcards
To learn
What is an acoelomate?
an animal without a coelom.
What is a coelom?
In animals, a fluid-filled body cavity surrounded entirely by mesoderm.
What is an angiosperm?
A flowering plant (phylum Anthophyta) that has seeds enclosed in fruits.
What does triploblastic mean?
Having a body with three germ layers: ectoderm, mesoderm, and endoderm.
What does diploblastic mean?
Having a body with only two germ layers: ectoderm and endoderm.
What is a gymnosperm?
A plant that produces seeds that are not enclosed in fruits.
What is the taxonomy of Spruce
Domain: Eukarya
Kingdom: Plante
Phylum: Coniferophyta
Genus: Picea
Is Picea (Spruce) non-vascular or vascular?
Vascular
What is the dominant generation in Picea (Spruce)?
Sporophyte
What is the habitat of Picea (Spruce)?
Boreal Forest of Saskatchewan
How does Picea (Spruce) obtain food/energy?
Through photosynthesis
Is Picea (Spruce) sessile or motile?
Sessile
Name one adaptation of Picea (Spruce) to its habitat.
Tracheids in vascular tissue allow water transport to higher parts, enabling the tree to grow taller.
What is the purpose of needle-like leaves with a thick waxy cuticle in Picea (Spruce)?
To prevent water loss
What is the dominant generation in Lilium (Prairie Lily)?
Sporophyte
How is pollen dispersed in Picea (Spruce)?
By wind, carrying pollen from male to female cones.
Describe the reproductive structure of male cones in Picea (Spruce).
Pollen cones (male) have tightly packed leaves (sporophylls) containing microsporangia and pollen sacs that produce pollen.
Describe the reproductive structure of female cones in Picea (Spruce).
Ovule cones (female) have ovuliferous scales with two ovules that produce female gametophytes inside a protected sporangium.
What is the reproductive cycle of Picea (Spruce) following fertilization?
Fertilization → Zygote → Embryo (protected by seed) → Maturation → Seed dispersal → Germination into a new sporophyte plant.
What is the taxonomy of the Prairie Lily
Domain: Eukarya
Kingdom: Plante
Phylum: Anthophyta
Genus: Lilium
Is Lilium (Prairie Lily) non-vascular or vascular?
Vascular
Is Lilium (Prairie Lily) unicellular or multicellular?
Is Lilium (Prairie Lily) unicellular or multicellular?
What is the habitat of Lilium (Prairie Lily)?
North America, grasslands, slough margins, and the undergrowth of northern forests (mainly beneath deciduous trees).
Name one adaptation of Lilium (Prairie Lily) for pollination.
Large, sticky pollen grains that attach to pollinators.
What is the purpose of nectar in Lilium (Prairie Lily)?
It is produced at the bases of sepals as a reward for pollinators, mainly bees.
Describe the reproduction method of Lilium (Prairie Lily).
Seeds are dispersed by animals, and fruits protect seeds, maturing in the ovaries.
What is the function of sepals in a flower like Lilium?
They are part of the flower’s bud and protect other flower parts (typically green
What is the role of petals in flowers?
To attract and guide pollinators with their bright colors.
What is the stamen in a flower?
The male organ of the flower, composed of a slender filament and an anther that produces pollen.
What does the anther do in Lilium?
It is the pollen-producing organ, containing microsporangia that produce pollen grains.
What is the carpel in a flower?
The female organ of the flower, including the pistil, stigma, style, and ovary.
Describe the pistil structure in Lilium.
Made up of fused carpels with a stigma (pollen receptor), style (stalk-like portion), and ovary (contains ovules).
