Antibiotics are chemicals produced by living organisms that are used to kill or inhibit the growth of other infectious micro-organisms. Most antibiotics prevent the growth of microorganisms‚ which they act on instead of completely killing them. Antibiotics are extra cellular products meaning that they can be extracted for use; Penicillin is an example of this as it comes from the fungus Penicillium notatum. Hormones are chemicals that transfer information and instructions between cells in animals

Structure & Function of Plants Review: Plant Structure‚ Growth‚ and Development I 1. How does the vascular tissue system enable leaves and roots to function together in supporting growth and development of the whole plant? 2. When you eat the following‚ what plant structure are you consuming? Brussels sprouts‚ celery sticks‚ onions‚ and carrot sticks. 3. Characterize the role of each of the three tissue systems in a leaf. 4. Describe at least three specializations in plant organs and

Introduction To differentiate between bacteria‚ fungi and yeast‚ we plant four different microbes in plates under the same environment for one week and compare the growth of the four microbes by macroscopic and microscopic observation. Meanwhile‚ the diversity of bacteria and fungi in humans‚ the environment and wood could be observed. In addition‚ the four substrates are cultured in two media‚ MEA and NA‚ under the same condition. Thus‚ how nutrients affect the growth of bacteria and fungi could

Ty Yarbrough Introduction The purpose of this lab was to recognize the stages as well as events of mitosis and meiosis in a plant cell or an animal cell. The relative duration of each stage in the cell cycle will also be learned during this lab. By doing this lab we will also create a model of and understand the process of crossing over. This lab also helps students understand the similarities along with differences between mitosis and meiosis. Purpose The objectives of the lab were to

Imagine a busy factory making the latest must-have toy. Whether they make bicycles‚ cell phones‚ or hot air balloons‚ most factories are set up the same way. All factories have outside walls that protect and support them and inside walls that create different work areas. They usually have a production line where a product is put together and an executive department that decides what product is made. A finishing department processes and prepares the product for shipping‚ and a packaging department

Plants and animals have a lot of things in common so much in fact i couldn’t fit half of them into this essay‚ there similarities and differences span from the smallest things like cells to huge thing like the whole organism. One thing that plants and animals both have in common is the fact that they adapt‚ the main thing isn’t that they adapt though it’s why they do it. Animals‚ plants‚ and humans all share the same thing they have a will to live in different ways maybe or some might want to live

Animals have been used in countless numbers of experiments ever since humans first developed a curiosity of how the human body works. Due to opening up a human in ancient times being not only taboo but also considered blasphemous to God‚ animals were used as substitutes to understand the human anatomy. It was relatively recently that humans started to use animals to understand diseases and test new chemicals we have developed. These animals have helped humanity advance to where it is today‚ and we

Compare the size of cheek cell and onion cell DCP: Introduction: In this experiment‚ Onion cells (Allium cepa) Cheek cells (Homo sapiens) were measured and compared. The aim of this experiment is to find out how both cells differ by comparing their size. Onion cells (Allium cepa) is plant cell and Cheek cells (Homo sapiens) is an animal cell. Hypothesis: The size of an animal cell (Homo sapiens) should be smaller than a plant cell (Allium cepa). Because a plant cell has cell wall which
