with what you observed for tomato plants? With both plants the photosynthesis rate increased while the light intensity increased. 2. Photosynthetic saturation is the maximum rate of photosynthesis. What value of light intensity produced photosynthetic saturation in corn leaves? 804 Lab Summary Address the following points in a 100-to 200-word summary: The purpose of this lab was to figure out the reactions of photosynthesis as the light intensity increased in tomato and corn plants.

ADAPTATIONS * Define the term adaptation and discuss the problems associated with inferring characteristics of organisms as adaptations for living in a particular habitat. An adaptation is any feature or characteristic that helps an organism survive in its environment. Adaptations can be classified as either structural‚ physiological or behavioural. When studying organisms and relating the chances of survival to body structure‚ physiology and behaviour‚ biologists are always wary of inferring

environmental extremes through specific defense mechanism [3]. The most important contributions leaves make to our planet’s ecosystem are through their processing of oxygen and carbon dioxide. Oxygen‚ though a waste product of photosynthesis is essential to plant‚ animal‚ and human survival. As leaves break down carbon dioxide and release oxygen‚ they also help determine global climate patterns [4]. On the other side‚ a block is a molded rectangular brick

dioxide enters. I predict that the stomatal density on high leafs is higher than on low leafs. During photosynthesis the chloroplasts in the leaf cells synthesize ATP from ADP as a result of exposure to light‚ while oxygen is produced as a by-product of the photosynthetic reaction. Carbon dioxide‚ which enters the plant through diffusion via the stomata‚ is needed for this process (photosynthesis) to occur. When the chloroplasts in the leafs cell is exposed to higher light intensities‚ more ATP is

Abiotic: non-living factors or components‚ e.g. soil‚ water‚ wind‚ etc… 2.1.2 Trophic level: is the position that an organism or a group of organisms in a community occupies in a food chain. 2.1.3 A food chain shows the flow of energy from one organism to the next. A food web is a complex network of interrelated food chains. Producers (autotrophs): manufacture their

cell lack the pigments‚ either because plastids are not present or the plastid cannot complete the manufacture of the pigment apparatus. White‚ therefore‚ is where color is missing. The zones where chloroplasts are not present are zones where no photosynthesis will occur‚ hence a variegated leaf has a lowered potential to fix carbon dioxide into sugars‚ and as a consequence‚ a variegated plant also tends to grow more slowly. Variegated leaves occur rarely in nature but are extremely common among indoor

55. a) Cuticles on the outermost layer of angiosperms are clear‚ which allows for light to pass through. The leaf is shaped in a way that will allow it to absorb more sunlight and be more efficient. Photosynthesis takes place in the spongy parenchyma and the palisade parenchyma. In order to obtain food‚ it is controlled by the stoma which controls the passage of gas and water. b) Water and food is transported through the xylem. The water will eventually be transported to the leaf tissue while the
