Plant Structure and Function

Plant Structure and Function

• Ground Tissue is important for photosynthesis and food storage and provides structure.
• Dermal Tissues prevent water loss, which is essential for photosynthesis.
• Xylem transports water from the roots to the rest of the plant, including the leaves, supplying the water needed for photosynthesis.
• Phloem transports glucose (sugar), which is produced during photosynthesis, to different parts of the plant for growth and energy.
• Stomata facilitate gas exchange, allowing carbon dioxide to enter and oxygen to be released. They close when plants lose too much water, which happens faster in plants with more leaves due to the presence of more stomata.
• Guard Cells control the opening and closing of stomata by regulating the intake and release of gases.
• Meristematic Tissue contains stem cells, allowing the plant to grow by constantly producing new cells for various organs.
• Photosynthetic Organisms like zooxanthellae are essential for producing glucose and oxygen, which are crucial for many ecosystems.
• Ovules develop into seeds, providing protection for the developing embryo. This adaptation offers an advantage to seed-producing plants over non-seed producing plants.
• Ovary develops into the fruit, which helps to attract animals to disperse seeds.

Photosynthesis

• Reactants of photosynthesis are carbon dioxide and water.
• Light energy is required to drive the process of photosynthesis.
• Products of photosynthesis are glucose (sugar) and oxygen.
• Increasing the amount of light increases the rate of photosynthesis because light is the energy source for the process.

Cellular Respiration

• ATP is the primary energy currency of cells and is produced through cellular respiration.
• Aerobic respiration requires oxygen for the process.
• Anaerobic respiration (fermentation) does not require oxygen. It is used by muscle cells when oxygen is scarce, converting pyruvate to lactic acid.

This quiz examines the various plant tissues and their roles in growth, nutrient transport, and photosynthesis. Topics include ground tissue, dermal tissue, xylem, phloem, stomata, and guard cells. Test your knowledge on how these components contribute to plant health and function.
