Study Notes
Plant Biology
- The main function of a flower in angiosperms is to produce seeds.
Gymnosperms
- Seeds of gymnosperms come from ovules in cones.
Phloem Tissue
- Companion cells in phloem tissue have a primary role in supporting sieve cells.
Bryophytes
- The dominant generation in bryophytes is the gametophyte.
- A characteristic of bryophytes is that they are non-vascular plants.
- Marchantiophyta, a subcategory of bryophytes, is known for its flattened, ribbon-like appearance.
Plant Reproduction
- Double fertilization occurs in angiosperms.
Photosynthesis
- The main difference between C3 and C4 photosynthesis is the way they fix CO2.
Nutrient Absorption
- The primary method of nutrient absorption in bryophytes is through their leaves.
Sporophytes and Gametophytes
- In bryophytes and ferns, sporophytes and gametophytes are capable of performing photosynthesis.
Plant Anatomy
- The primary function of periderm in plants is to protect them from damage and water loss.
Seed Dispersal
- Barochory is related to seed dispersal through gravity.
Water Efficiency
- CAM (Crassulacean Acid Metabolism) plants have the highest water efficiency.
Respiration
- Respiration does not occur in viruses.
Ferns
- Ferns have a dominant sporophyte generation.
Vascular Bundles
- Xylem and phloem tissues together form vascular bundles.
