and the fibrous root system; both are crucial for plant growth. Second‚ the stems‚ carry water and nutrients taken up by the roots and carry it to the leaves to be produced into food. Inside the stems are the xylem cells‚ which move water‚ and the phloem cells‚ which move food. Third is the leaves‚ which are the food making factories of the plant. Leaves come in a variety of sizes‚ and can be simple or compound. Photosynthesis takes place in the leaves‚ where it uses carbon dioxide‚ water‚ chlorophyll

manganese are also abundant in Banana. Putting all of the nutritional figures together‚ it clearly shows that banana is one of the healthiest fruits. There is a protective outer layer (a peel or skin) with numerous long‚ thin strings‚ known as the phloem bundles‚ which run lengthwise between the skin and the edible inner portion. They are strings that go up and down the length of bananas and enable to help distribute nutrients to every part of the growing bananas. Toothpaste is a paste or gel dentifrice

Distinguish between the strategies used by autotrophs and heterotrophs to obtain free energy for cellular processes. In other words‚ how and in what form does each capture and store that energy? 2. Explain how photosynthesis differs in eukaryotic organisms (with organelles such as chloroplasts) and in prokaryotic organisms (single-celled‚ no organelles). 3. How does a metabolic

HW Review for Photosynthesis exam: Due Monday March 28 Reminder your lab write up will be a next week. If your lab is this Friday you also will get a week to complete your full lab write-up. Sample questions: 1. twenty-five plants were placed in each of four closed containers and then exposed to light conditions shown in the data table below. All other environmental conditions were held constant for a period of 2 days. At the beginning of the investigation‚ the quantity of CO2 present in each closed

reproductive fitness. Unlike angiosperms‚ mosses (bryophytes) have not achieved the widespread terrestrial success. They are not as successful as angiosperms due to the fact that they are non vascular. Non-vascular means that they have no xylem or phloem tissue. This lack of vascular tissue is the cause of the small size of bryophytes. Bryophytes gametophytes are the dominant stage of the life cycle. They need water for the sperm to swim to the egg during fertilization. Since their sporophytes are
