Ap Biology Lab
To begin, in this lab we studied the structures of leaves under a microscope. A leaf is best described as a major photosynthetic organ of green plants. Plants carry out the process of photosynthesis to convert carbon dioxide and water into oxygen and glucose for usable energy. This can be represented in a general equation which is 6CO2 + H2O -------> (sunlight and chlorophyll) C6 H12 O6 +6O2. Initially, the leaf is protected by the upper and lower epidermis as well as the cuticle. The leaf first needs to obtain sunlight which enters through the cuticle. Eventually, the sunlight seeps through to the upper epidermis and makes its way into the mesophyll. The mesophyll contains chloroplast which are necessary organelle in order for the leaf to

Health officials realized that the mysterious illness was not caused by a bacterium because the pathogen would be identified quickly in comparison to a virus, which is more complicated (CBC, 2013). 2. It was hard to identify the infectious agent because SARS presented as flu-like symptoms with a rapid onset and is similar to the common flu (CBC, 2013). People who had other underlying health problems made it difficult to identify symptoms of SARS because it made it hard to differentiate (CDC, 2013).

Belonging To The Plantae Kingdom
1360 Words | 6 PagesThese complex organisms consist of two organ systems, the root system and the shoot system. The shoot system is an above ground organelle system, this is where the leaves, stems, buds, flowers (depending on the plant) and fruits (depending on the plant) are found. Thus, therefore, meaning that the root system is the below ground system and includes the roots, rhizomes and tubers. There are three types of plant cells which are formed in the meristem (tissue in most plants that contain undifferentiated cells, the cells produced here help various organs of the plant and help with the growth of the plant.) The first plant tissue grouping is Dermal, the Dermal system looks after the covering of the plant, and can be broken down into many subsystems.

John Stevens Henslow also took him under his wing and inspired him to travel. While reading the Henslow suggested Personal Narrative by Alexander Von Humboldt, Charles started thinking about all of the places in South and Central America that Humboldt had traveled to. Henslow setup geological training with Reverend Professor Adam Sedgwick when Charles expressed interest in going to the Canary Islands. That was when He developed his love and skill for geology.

Gene Transfer Lab Report
1030 Words | 5 PagesTransfection: One of the methods of gene transfer where the genetic material is deliberately introduced into the animal cell in view of studying various functions of proteins and the gene. This mode of gene transfer involves creation of pores on the cell membrane enabling the cell to receive the foreign genetic material. Transfection can be carried out using calcium phosphate (i.e. tricalcium phosphate), by electroporation, by cell squeezing or by mixing a cationic lipid with the material to produce liposomes which fuse with the cell membrane and deposit their cargo inside. The choice of methods of DNA transfer depends upon the target cells in which transformation will be performed. It also depends upon the objectives of gene manipulation.
Why Do Plants Grow Eukaryotic Organisms?
819 Words | 4 PagesOne of these organelles is the chloroplast. Chloroplasts are found in a plant's leaf cells, and contain a molecule of green pigment called chlorophyll, which gives many plants their green colour. The chloroplasts of a plant's cell are where photosynthesis occurs, the process in which light energy from the sun is converted to chemical energy in the form of consumable sugars or glucose (see Figure 1) (Huxley and Walter, 2014). This radiant energy from the sun is a plant's major source of energy. Oxygen is also a product of photosynthesis.
Comparing The Kingdoms Of Plantae And Animal Cells
247 Words | 1 PagesAlthough both Kingdoms of Plantae and Animalia have cells, tissues and organs; there are many differences within their cell physiology, development, biology and growth. Separated by about 1.5 billion years of evolutionary history, they are two major multicellular groups of the Domain Eukaryota, which share features such as mitochondria and nuclei, but has evolved their multicellular organization independently by using the same initial tool kit—the set of genes inherited from their common unicellular eukaryotic ancestor (Alberts 2002). Plant cells are large and rectangular and have a fixed shape, whereas animal cells are much smaller and circular. Both plant and animal cells have flexible membranes, but because plant cells are additionally encased
Why Do Animal Cells Use For Photosynthesis
1023 Words | 5 PagesDuring this process, molecules grab energy from electrons while moving around. This process occurs in the inner membrane of the mitochondria. Photosynthesis takes place within the chloroplasts of a plant cell. The chlorophyll within the chloroplast absorbs the light while carbon dioxide is grabbed from the air through an area of the leaves of a plant called the stroma. Water is also obtained through the roots of a plant which absorb water through root hairs.

722 Words | 3 PagesThey also contain xanthophyll which makes the leaves look yellow and carotene is what makes the leaves turn orange (Jensen, 2015). During the spring and summer the leaves on trees are green because of photosynthesis occurs. Photosynthesis is the progress of how leaves gets food and water (Jensen, 2015). The chlorophyll gets light from the sun and water from the ground, and then it turns into food and stores it in the leaf (Jensen, 2015).
