Study Notes
Basic Organs of Plants
- Three basic organs of plants are roots, stems, and leaves.
- Roots anchor the plant, absorb water and nutrients, and store food.
- Stems support leaves and flowers, transport fluids between roots and leaves, and store nutrients.
- Leaves are primarily involved in photosynthesis and gas exchange.
Root System Functions
- The root system stabilizes the plant by securing it in the soil.
- Roots absorb water and essential minerals from the soil to support growth.
- They store energy and nutrients, helping the plant survive adverse conditions.
Water and Mineral Absorption
- In most plants, water and minerals are primarily absorbed through the root hairs.
- Root hairs increase surface area, enhancing absorption efficiency.
Meristem Function
- Meristem tissue is responsible for plant growth, allowing for continuous cell division.
- It is located at the tips of roots and stems, enabling elongation and new tissue formation.
Evolutionary History Reflection
- Plant evolution reflects adaptation to terrestrial and aquatic environments through structural and functional changes.
- Traits like cuticles and stomata evolved for water retention and gas exchange in land plants.
