Boreal Forest of Saskatchewan

Question 9

How does Picea (Spruce) obtain food/energy?

Answer 9

Through photosynthesis

Question 10

Is Picea (Spruce) sessile or motile?

Answer 10

Sessile

Question 11

Name one adaptation of Picea (Spruce) to its habitat.

Answer 11

Tracheids in vascular tissue allow water transport to higher parts, enabling the tree to grow taller.

Question 12

What is the purpose of needle-like leaves with a thick waxy cuticle in Picea (Spruce)?

Answer 12

To prevent water loss

Question 13

What is the dominant generation in Lilium (Prairie Lily)?

Answer 13

Sporophyte

Question 14

How is pollen dispersed in Picea (Spruce)?

Answer 14

By wind, carrying pollen from male to female cones.

Question 14

Describe the reproductive structure of male cones in Picea (Spruce).

Answer 14

Pollen cones (male) have tightly packed leaves (sporophylls) containing microsporangia and pollen sacs that produce pollen.

Question 15

Describe the reproductive structure of female cones in Picea (Spruce).

Answer 15

Ovule cones (female) have ovuliferous scales with two ovules that produce female gametophytes inside a protected sporangium.

Question 16

What is the reproductive cycle of Picea (Spruce) following fertilization?

Answer 16

Fertilization → Zygote → Embryo (protected by seed) → Maturation → Seed dispersal → Germination into a new sporophyte plant.

Question 17

What is the taxonomy of the Prairie Lily

Answer 17

Domain: Eukarya
Kingdom: Plante
Phylum: Anthophyta
Genus: Lilium

Question 18

Is Lilium (Prairie Lily) non-vascular or vascular?

Answer 18

Vascular

Question 19

Is Lilium (Prairie Lily) unicellular or multicellular?

Answer 19

Is Lilium (Prairie Lily) unicellular or multicellular?

Question 20

What is the habitat of Lilium (Prairie Lily)?

Answer 20

North America, grasslands, slough margins, and the undergrowth of northern forests (mainly beneath deciduous trees).

Question 21

Name one adaptation of Lilium (Prairie Lily) for pollination.

Answer 21

Large, sticky pollen grains that attach to pollinators.

Question 22

What is the purpose of nectar in Lilium (Prairie Lily)?

Answer 22

It is produced at the bases of sepals as a reward for pollinators, mainly bees.

Question 23

Describe the reproduction method of Lilium (Prairie Lily).

Answer 23

Seeds are dispersed by animals, and fruits protect seeds, maturing in the ovaries.

Question 24

What is the function of sepals in a flower like Lilium?

Answer 24

They are part of the flower's bud and protect other flower parts (typically green

Question 25

What is the role of petals in flowers?

Answer 25

To attract and guide pollinators with their bright colors.

Question 26

What is the stamen in a flower?

Answer 26

The male organ of the flower, composed of a slender filament and an anther that produces pollen.

Question 27

What does the anther do in Lilium?

Answer 27

It is the pollen-producing organ, containing microsporangia that produce pollen grains.

Question 28

What is the carpel in a flower?

Answer 28

The female organ of the flower, including the pistil, stigma, style, and ovary.

Question 29

Describe the pistil structure in Lilium.

Answer 29

Made up of fused carpels with a stigma (pollen receptor), style (stalk-like portion), and ovary (contains ovules).
