Through this experiment‚ Egeria densa was observed using a microscope. The task was to observe and identify the different types of cell‚ cytoplasmic streaming‚ and plasmolysis of Egeria densa. First‚ the microscope was examined and investigated to master the use of the equipment. A microscope slide grid which was on the slide glass was required to be seen clearly using 4x‚ 10x and 30x. During the latter part of the experiment‚ the Egeria densa was observed using the microscope to understand the

Light is everywhere in our world. We need it to see: it carries information from the world to our eyes and brains. Seeing colors and shapes is second nature to us‚ yet light is a perplexing phenomenon when we study it more closely. Here are some things to think about: Our brains and eyes act together to make extraordinary things happen in perception. Movies are sequences of still pictures. Magazine pictures are arrays of dots. Light acts like particles—little light bullets—that stream from the

Introduction Man has propagated plant material almost as long as he has cultivated the land to produce food. For a long time‚ plant material was propagated mainly by using the seeds of existing plants. Better methods were discovered over time‚ methods that allowed the farmer to retain the desirable qualities of the plant material‚ while eliminating some of the less desirable qualities. Through these methods‚ the farmer was also able to eliminate the variations between plants of the same cultivar and produce

PLANT CELL Introduction Plant cell is the basic unit of structure and function in nearly all plants. The range of specialization and the character of association of plant cells are very wide. In the simplest plant forms a single cell constitutes a whole organism and carries out all the life functions. In just slightly more complex forms‚ cells are associated structurally‚ but each cell appears to carry out the fundamental life functions‚ although certain ones may be specialized

Caffeine is a xanthine alkoid compound that acts as a stimulant. In humans‚ caffeine can help with alertness and wards off drowsiness. Caffeine can be found in cocoa‚ coffee beans‚ and tea leaves. It can also be found in over the counter medication. One of the newest sources of caffeine are energy drinks. Many people drink caffeine making it very popular and a widely consumed product. Over 90% of the population consumes caffeine. Even though caffeine is very popular it has some negative effects to

The factors affecting plant yield: light level Abstract The factors affecting Zea mays‚ maize (C4) and Pisum sativa‚ or pea (C3) plant yield and growth patterns placed under shade and full sunlight were investigated. 20 plantlets placed into four vermiculite compost pots (5 from each plantlet) and submitted to fertilizer or no fertilizer. And after 4 weeks the results showed that maize grown in light with no fertilizer had a higher relative growth rate and root to shoot ratio indicating the allocation
Premium Photosynthesis Carbon dioxide
Parts of plants Each part of a plant has a very important function. All plants produce flowers for the same reason: to make seeds so another plant can grow. Leaves: These are the parts of the plant where food is made by photosynthesis. Leaves take in carbon dioxide from the air‚ water from the soil‚ and energy from the sunlight. During photosynthesis‚ the leaves use light energy to change carbon dioxide and water into food. (sugar) Flowers: These are the reproductive parts of

Imbibition in Kidney Beans * Aim of Experiment: * To investigate the effect that emersion in salt solutions has on imbibition in kidney beans. * Safety Considerations: * One must use extreme caution when working with chemicals. Always wear protective goggles and gloves when handling them. KCl is slightly hazardous in case of skin contact‚ eye contact‚ ingestion‚ or inhalation. In case of eye contact‚ immediately flush eyes with plenty of water for at least 15 minutes. Seek

Excellent; I couldn’ t have written a better paper myself. DIVERSITY OF PLANTS Plants evolved more than 430 million years ago from multicellular green algae. By 300 million years ago‚ trees had evolved and formed forests‚ within which the diversification of vertebrates‚ insects‚ and fungi occurred. Roughly 266‚000 species of plants are now living. The two major groups of plants are the bryophytes and the vascular plants; the latter group consists of nine divisions that have living members. Bryophytes
