Explanation

• The evaporation of water from the leaves, also known as transpiration, creates a negative pressure that pulls water up the xylem from the roots to the leaves.
• This process is known as the transpiration-cohesion theory.

Explanation

• Phloem is the vascular tissue responsible for transporting organic materials, such as sugars, amino acids, and other nutrients.
• Produced by photosynthesis from the leaves to the rest of the plant, including roots, stems, and fruits.

Explanation

• Photolysis is the process by which water (H2O) is split into hydrogen ions (H+), electrons, and oxygen (O2) in the presence of light.
• This process occurs in the thylakoid membranes of chloroplasts during photosynthesis and is driven by light energy.

Explanation

• The dark reaction, also known as the Calvin cycle.
• It is a light-independent reaction that occurs in the stroma of the chloroplast.
• This process uses the energy from ATP and NADPH produced in the light-dependent reactions to convert carbon dioxide into glucose.

Explanation

• The light-dependent reactions (also known as the Hill reaction) occur in the thylakoid membranes of the chloroplast.
• Thylakoids are specialized membranous structures found in chloroplasts, where light energy is absorbed and converted into ATP and NADPH.

Explanation

• Glucose is the fundamental molecule produced during photosynthesis.
• It is then used by the plant cell as energy and building block for the synthesis of other organic compounds.
• Like cellulose, starch, and other carbohydrates.

Explanation

The secondary cell wall, found in plant cells, is primarily composed of:

• Cellulose (a polysaccharide, the main component of plant cell walls)
• Lignin (a complex organic compound that provides strength and rigidity)

Explanation

• Producers, also known as autotrophs.
• They are organisms that can produce their own food through photosynthesis, using water (H2O), carbon dioxide (CO2), and sunlight to produce glucose and oxygen.
