Q

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

A

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

14
Q

How is pollen dispersed in Picea (Spruce)?

A

By wind, carrying pollen from male to female cones.

14
Q

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

A

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

15
Q

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

A

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

16
Q

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

A

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

17
Q

What is the taxonomy of the Prairie Lily

A

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

18
Q

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

A

Vascular

19
Q

Is Lilium (Prairie Lily) unicellular or multicellular?

A

Is Lilium (Prairie Lily) unicellular or multicellular?

20
Q

What is the habitat of Lilium (Prairie Lily)?

A

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

21
Q

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

A

Large, sticky pollen grains that attach to pollinators.

22
Q

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

A

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

23
Q

Describe the reproduction method of Lilium (Prairie Lily).

A

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

24
Q

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

A

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

25
Q

What is the role of petals in flowers?

A

To attract and guide pollinators with their bright colors.

26
Q

What is the stamen in a flower?

A

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

27
Q

What does the anther do in Lilium?

A

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

28
Q

What is the carpel in a flower?

A

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

29
Q

Describe the pistil structure in Lilium.

A

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