Study Notes
Plant Structures and Their Functions
- Roots anchor the plant in the soil and absorb water and nutrients from the soil.
- Stems provide support to the plant and transport water, nutrients, and sugars between the roots and leaves.
- Leaves are the primary site for photosynthesis, converting sunlight, carbon dioxide, and water into glucose and oxygen.
- Leaves also regulate water vapor and gas exchange.
- Flowers are reproductive structures that produce seeds through the combination of male (stamens) and female (pistils) parts.
- Fruits are mature ovaries of flowers that contain seeds, protecting and dispersing them to aid in reproduction.
- Seeds are fertilized ovules of flowers that contain the embryo of the plant, disperse to new locations, and germinate into new plants.
- Meristems are regions of actively dividing cells where growth occurs, found in the tips of roots and shoots.
Main Parts of a Plant
- A plant consists of two main parts: the root and shoot, which grow in opposite directions.
Shoot
- The shoot is composed of stem, leaves, flowers, and fruits.
- The stem provides structural support, allowing the plant to stand upright.
- The stem acts as a transport system, carrying water and minerals from the roots to the leaves and distributing food prepared by the leaves to other parts of the plant.
- Branches are extensions that grow from the stem.
Leaves
- Leaves are attached to the stem and branches.
- The green color of leaves is due to the presence of chlorophyll, which enables food preparation through photosynthesis.
- Leaves have tiny openings called stomata, responsible for gas exchange, taking in oxygen and releasing carbon dioxide.
Flowers
- Flowers are the reproductive structures of the plant, varying in shape, size, and color.
- Many flowers undergo pollination, eventually developing into fruits.
Roots
- Roots anchor the plant firmly in the ground, providing stability.
- Roots absorb water and essential minerals from the soil, supporting the plant's growth and development.
This quiz covers the different parts of a plant, including roots, stems, leaves, and flowers, and their respective roles in supporting the plant's growth and survival.
