Evergreen & Deciduous
9SCIE - Plants as Producers
Respiration and photosynthesis can be thought of as opposites to each other.
- Give the equation for respiration
- Give the equation for photosynthesis
- Discuss with the person next to you why plants and animals are important for each others survival using the equations above.
- Leaves are little factories that create energy for the plant!
- They combine carbon dioxide and water inside chloroplasts
- Evergreen trees has leaves throughout the year, and they are always green.
- Some tauria are pine, eucalyptus and rainforest trees.
- Some evergreen tree leaves can live up to 30 years!
- Shed their leaves as an adaptation to a cold or dry/wet season.
- This helps them survive when there are less nutrients, sunlight, water etc. available
- When cold, organic material (dead plants & animals) decays slowly (fewer nutrients)
Adaptations of Leaves
- Broad and flat to capture lots of sunlights
- Veins carry water to the leaf and carry sugar to the rest of the plant
- Some cells contain chloroplasts with chlorophyll
- Have stomata on the underside to allow gasses in and out
What is Glucose Used For?
- Used in respiration straight away to produce energy
- Converted into starch for long-term energy storage
- Used to make new chemicals like proteins, fats and other sugars
