Study Notes
Plant Structure and Function
- Roots anchor plants in the soil and absorb water and nutrients.
- Stems provide support, transport water and nutrients between roots and leaves, and position leaves to receive sunlight.
- Leaves are responsible for photosynthesis, capturing sunlight and exchanging gases.
- Flowers are involved in reproduction, producing seeds that grow into new plants.
- Fruits develop from flowers and contain seeds.
Photosynthesis
- Plants produce food through photosynthesis, using sunlight, carbon dioxide, and water to create glucose (sugar) and oxygen.
Gas Exchange in Leaves
- Stomata are tiny openings on the underside of leaves that allow for gas exchange.
- Carbon dioxide enters the leaf through stomata, while oxygen produced during photosynthesis exits through stomata.
Pollination and Reproduction
- Pollination is the transfer of pollen from the male part of a flower to the female part.
- Pollination is essential for fertilization and the production of seeds.
Photosynthesis
- Plants use sunlight to convert carbon dioxide and water into glucose and oxygen.
- This process primarily takes place in the leaves.
Importance of Flowers
- Flowers are essential for plant reproduction.
- They produce seeds through pollination and fertilization.
Fruits and Seed Dispersal
- Fruits protect seeds.
- They also aid in seed dispersal.
- Animals eating fruits carry and deposit seeds in new locations, facilitating plant propagation.
Role of Leaves
- Leaves are the primary sites for photosynthesis.
- They capture sunlight and exchange gases through stomata, enabling food production for the plant.
Chlorophyll
- Chlorophyll is the green pigment in leaves and is crucial for photosynthesis.
- It absorbs light energy from the sun.
Water Transport
- Water travels through a plant through a system of vascular tissues called xylem.
- Xylem transports water from the roots upwards to the rest of the plant.
