During photosynthesis, what is the primary role of the stomata?
During photosynthesis, what is the primary role of the stomata?
- Distributing manufactured sugars throughout the plant.
- Absorbing water and minerals from the soil.
- Allowing carbon dioxide to enter the plant. (correct)
- Releasing oxygen into the atmosphere.
What is the key function of chlorophyll in the process of photosynthesis?
What is the key function of chlorophyll in the process of photosynthesis?
- Absorbing water from the soil.
- Absorbing light energy. (correct)
- Releasing oxygen into the atmosphere.
- Transporting manufactured sugars.
What best describes the transformation of raw sap into elaborated sap in a plant?
What best describes the transformation of raw sap into elaborated sap in a plant?
- Elaborated sap transforms into raw sap as it releases oxygen into the atmosphere.
- Raw sap is the result of photosynthesis, while elaborated sap is the initial mixture of water and minerals.
- Raw sap, containing manufactured sugars and water, becomes elaborated sap after absorbing minerals from the soil.
- Raw sap is converted into elaborated sap when manufactured sugars are mixed with water and distributed throughout the plant. (correct)

Study Notes
Photosynthesis Process
- Photosynthesis uses light energy from the sun to convert carbon dioxide (CO2) and water (H2O) into glucose (sugar) and oxygen (O2).
- Light energy is absorbed by chlorophyll in chloroplasts.
- Carbon dioxide enters the leaves through stomata.
- Water is absorbed by the roots and transported to the leaves.
- Glucose is the plant's food source and also used in respiration.
- Oxygen is released into the atmosphere.
Plant Structure and Function
- Water and minerals are absorbed through roots and transported as "sap" throughout the plant.
- Minerals and water move up the plant from roots to leaves forming "raw sap."
- The glucose produced in photosynthesis is transported as "processed sap."
- Stomata are small openings on leaves that allow gas exchange (intake of CO2 and release of O2.)
- Roots absorb water and minerals to support the plant.
Photosynthesis Experiment (Elodea)
- Materials for the experiment likely include:
- Elodea plant
- Beaker
- Funnel
- Test tube
- Light source
- Graduated cylinder
- Water
- The bubbles produced in the experiment are oxygen.
- The purpose of the experiment is likely to demonstrate photosynthesis in an aquatic plant, while observing the release of oxygen.
