13.2/.3 - Plant Reproduction

Question 1

Asexual reproduction in plants

Answer 1

Uses stems, leaves, & roots

Grows through mitosis; genetically identical

Ex. Potatoes, strawberries, bryophyllum plants, & dandelions (roots)

Question 2

Grafting? Scion? Stock?

Answer 2

Grafting - joining two plants together; attaching a young branch
from one plant to the stem and root
of another plant

Scion - desirable plant species (detached young branch)

Stock - plant well-suited for environment. Scion is grafted onto stock.

Question 3

Monocots vs dicot seeds

Answer 3

Monocot - 1 part (looks like corn/pomegranate) aka 1 cotyledon

Dicot - 2 parts (looks like 2 beans side-by-side) aka 2 cotyledons

Question 4

Sexual reproduction in gymnosperms & angiosperms

Answer 4

Gymnosperms - uses cones; microspore (male) & megaspore (female) are formed

Angiosperms - uses flowers (see other flashcard for info)

Question 5

Flower sexual reproduction parts

Answer 5

Stamen - male reproductive part
- Anther: floral organ that produces pollen grains
- Filament: Thin stalk that support anther

Carpel - Female reproductive part
- Stigma: sticky surface; landing area for pollen grains
- Style: Tube-like stalk that leads to ovary
- Ovary: 1 or more ovules that makes seed when fertilized

Question 6

Self-pollination vs. Cross-pollination

Answer 6

Self-pollination - Pollen goes from one flower to the same flower or another flower on the same plant

Cross-pollination - Pollen goes from one plant to another (same species)

Question 7

Different methods of pollination // Mechanisms of seed dispersal

Answer 7

Self-pollination, cross-pollination, animals & wind

Animals & wind also disperse seeds
