What are the two main functions of roots in a plant?
What are the two main functions of roots in a plant?
The roots anchor the plant into the ground and absorb water and minerals from the soil.
How do leaves contribute to the process of photosynthesis?
How do leaves contribute to the process of photosynthesis?
Leaves convert carbon dioxide and water into food using sunlight through photosynthesis.
What is the role of xylem and phloem in a plant?
What is the role of xylem and phloem in a plant?
Xylem carries water from the roots to the leaves, while phloem transports sugar from the leaves to the rest of the plant.

Study Notes
Plant Structure and Functions
- Roots: Absorb water and nutrients from soil, anchoring the plant firmly in the ground.
- Stem: Provides structural support for leaves, flowers, and fruits while transporting water and nutrients from roots to leaves.
- Flowers: Facilitate sexual reproduction in plants, attract pollinators for effective pollination.
- Leaves: Engage in photosynthesis, converting carbon dioxide and water into food using sunlight.
Seed Structure
- Embryo: A developing plant that includes the radicle (root) and plumule (shoot).
- Cotyledons: One or two seed leaves; monocots have one, dicots have two; they contain starch to nourish the seedling.
- Seed Coat: Protective outer layer safeguarding the seed.
Germination Process
- Definition: Transition from seed to plant.
- Requirements: Requires water, oxygen, and warmth for successful germination.
Photosynthesis
- Function: Process by which plants synthesize food (starch and sugar) and oxygen using sunlight, water, and carbon dioxide.
- Location: Occurs primarily in leaves; specifically in chloroplasts.
- Stomata: Small openings in leaves facilitating gas exchange (oxygen and carbon dioxide); surrounded by guard cells which regulate their opening and closing.
Plant Transport Systems
- Xylem: Tubes that transport water from roots to leaves.
- Phloem: Tubes that distribute organic compounds like sugars from leaves to the rest of the plant.
- Veins: Networks within leaves that help transport food, water, and minerals.
Flower Structure
- Stamen: Male reproductive part consisting of anther (produces pollen) and filament.
- Carpel: Female part consisting of stigma (captures pollen), style, and ovary (contains ovules).
- Petals: Often colorful to attract pollinators.
Reproductive Processes
- Pollination: Transfer of pollen from anther to stigma of the same species flower.
- Fertilization: Fusion of pollen with ovule, leading to seed development.
Cellular Biology
- Cell: The fundamental unit of life capable of independent survival.
- Magnification: Total magnification calculated by multiplying eyepiece magnification by objective magnification (e.g., 10x eyepiece with 4x objective results in 40x total magnification).
