Study Notes
Reproductive Cells and Structures
- Reproductive cells known as gametes include egg cells and sperm cells, essential for sexual reproduction in many organisms.
- In plant roots, food storage occurs in the (root) cortex, serving as a reserve for nutrients.
Biological Processes
- Diffusion is the process where substances mix due to random molecular movement, crucial for nutrient uptake and gas exchange in organisms.
- The internode is the segment of a twig positioned between nodes, contributing to plant growth and structure.
Plant Dispersal and Growth
- Dispersal of dandelion seeds through the wind exemplifies how plants spread their progeny for reproduction, enhancing genetic diversity.
- The region of elongation in a root tip is responsible for cell lengthening, a key factor in root growth and soil penetration.
Pollination Mechanisms
- Certain grass species exhibit self-pollination in their underground flowers, as these flowers are incapable of being pollinated by others, ensuring reproduction in isolated environments.
Plant Response to Light
- Phototropism is demonstrated when plant seedlings bend toward a light source, showcasing how plants adapt to maximize light exposure for photosynthesis.
Flower Parts and Terminology
- Stigma functions as the pollen-receptive part of the flower (F).
- Style connects the stigma to the ovary, facilitating pollen transmission (G).
- Ovule is the element within the ovary that develops into seeds after fertilization (A).
- Receptacle supports the flower parts, serving as the base (C).
- Stamen represents the male reproductive organ, comprising anthers and filaments (E).
- Pedicel is the stalk that supports a single flower, linking it to the main stem (B).
