Study Notes
Vascular Tissue in Plants
- Transports water and nutrients throughout the plant.
- Xylem carries water upward from roots to leaves.
- Phloem carries sugars (produced during photosynthesis) from leaves to other parts of the plant.
Photosynthesis
- Process where plants use sunlight, water, and carbon dioxide to produce glucose (sugar) for energy.
- Takes place in chloroplasts, which contain chlorophyll.
Flower Structures
- Primarily involved in reproduction.
- Petals attract pollinators.
- Stamens produce pollen.
- Pistil contains the ovary, which houses the ovules.
Arthropods
- Belong to the phylum Arthropoda.
- Characterized by exoskeletons (hard outer coverings) and jointed appendages.
- Examples include insects, spiders, crustaceans.
Alternation of Generations
- Describes the life cycle of plants, alternating between a haploid (gametophyte) and a diploid (sporophyte) generation.
- The gametophyte produces gametes (sperm and egg), while the sporophyte produces spores.
Mitochondria
- Organelles found in animal cells, and most other eukaryotic cells.
- Responsible for cellular respiration, breaking down glucose to produce energy (ATP).
Invertebrates
- Lack a backbone (vertebral column).
- Make up the vast majority of animal species.
- Examples include insects, worms, mollusks, and crustaceans.
Body Cavity
- Fluid-filled space within the body that provides support, cushions organs, and aids in circulation.
- Found in most animal groups, such as annelids, arthropods, and vertebrates.
- Provides space for organ development and movement.
Plant Roots and Photosynthesis
- Roots absorb water and minerals from the soil.
- Water is transported through the xylem to leaves, providing the necessary component for photosynthesis.
Vertebrates vs. Invertebrates
- Vertebrates have a backbone (vertebral column).
- Invertebrates do not have a backbone.
- Vertebrates include mammals, birds, reptiles, amphibians, and fish.
Stem Functions
- Support the plant and hold leaves up for maximum sunlight absorption during photosynthesis.
- Transport water and nutrients between roots and leaves.
Open Circulatory System
- Blood flows through a system of open spaces (hemocoel) rather than enclosed vessels.
- Characteristic of arthropods such as insects, crustaceans, and arachnids.
- Allows for efficient movement of blood in smaller, less active animals.
