Questions and Answers

Name two features visible in the image of Rose sweet pea that indicate the flower is cross-pollinated.

Two features visible in the image of Rose sweet pea that indicate the flower is cross-pollinated are the presence of multiple stamens and a well-developed stigma.

What is meant by cross-pollination? List two other agents of pollination.

Cross-pollination refers to the transfer of pollen from the anther of one flower to the stigma of another flower. Two other agents of pollination are wind and insects.

Explain self-pollination.

Self-pollination refers to the transfer of pollen from the anther to the stigma within the same flower or within flowers of the same plant.

Outline the differences between mitosis and meiosis.

Mitosis is the process of cell division that produces two identical daughter cells, while meiosis is the process of cell division that produces four genetically different daughter cells and is involved in the formation of gametes for sexual reproduction. Signup and view all the answers

Study Notes

Cross-Pollination

Features:
- Different flower structures: The image shows the stigma and style are positioned above the anther.
- Brightly colored petals: Bright colors and pleasant scents can attract pollinators to the flowers.
Definition: Cross-pollination involves the transfer of pollen from the anther of one flower to the stigma of another flower of the same species.
Agents:
- Insects (like bees and butterflies)
- Wind

Self-Pollination

Definition: Self-pollination occurs when pollen from the anther of a flower is transferred to the stigma of the same flower or another flower on the same plant.

Chromosome Parts

Centromere: Constricted region of the chromosome where the sister chromatids attach.
Chromatids: Two identical copies of a chromosome joined at the centromere, formed during DNA replication.
Telomeres: Protective caps at the ends of chromosomes that prevent degradation of DNA.
Genes: Functional units of heredity located on chromosomes.

Mitosis vs. Meiosis

Mitosis:
- Purpose: Growth, repair, and asexual reproduction.
- Daughter cells: Two daughter cells genetically identical to the parent cell.
- Chromosomes: Number of chromosomes remains the same.
Meiosis:
- Purpose: Sexual reproduction.
- Daughter cells: Four daughter cells with half the number of chromosomes as the parent cell.
- Chromosomes: Number of chromosomes is halved.
- Genetic diversity: Generates genetic variation through crossing over and independent assortment.
