result of their random movement 2 Describe the importance of diffusion of gases and solutes and of water as a solvent. Gases Necessary for gas exchange in all living organisms Necessary for obtaining Carbon Dioxide and releasing oxygen during photosynthesis. Solutes (liquids) Dissolved salts dissolve through root hair cell. Absorption of dissolved food material in many organisms‚ like amoeba‚ bacteria and fungi is carried out through diffusion. Some digested food material is absorbed by diffusion

Plants undergo the process of photosynthesis‚ where they absorb light energy and convert it into sugar. This process expels oxygen‚ which all living things require to survive. In addition‚ plants are a food‚ and hence an energy source‚ for many living creatures‚ making them essential in the food chain. 3. Describe the purpose‚ process‚ and chemical and energy components of photosynthesis and the source of each component (e.g. CO2 is found in the air)? Chloroplast cells in the palisaide mesophyll

1.) Roots support photosynthesis and respiration by absorbing minerals and water and by storing organic nutrients. They also anchor the plant. Some roots have mycorrhizae‚ which increase the surface area and therefore increase the absorption. The endodermis‚ which is the innermost layer of cells in the root cortex‚ surrounds the vascular cylinder. It is the passage of minerals from the cortex into the vascular tissue. The stem has a system of nodes where leaves are attached. They have a waxy

SOLANO MARIANNE KRISTELLE E. YARRA INTRODUCTION Photosynthesis sustains almost all of the living world directly or indirectly. It is the process of converting light energy to chemical energy of sugars and other organic compounds. The process depends on the interaction between two sets of reactions‚ namely the

Objectives: To use the process of chromatography to separate plant pigments. To compare the plant pigments found in spinach and red leaf lettuce leaves. Hypotheses: I believe the spinach leaf in the acetone will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. I believe the spinach leaf in distilled water will have a higher pigment of chlorophyll a and the red leaf lettuce will have a higher pigment of anthocyanin. Discussion Questions:

increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate of photosynthesis will also increase in a linear trend. Carbon dioxide concentration is shown to be directly proportional to rate of photosynthesis ([CO2] ∝ rate of photosynthesis). The line of best fit
