Ngee Ann Poly trip bio photos

First observation: Viewing of pond water

This is a picture of a algae found in the pond water. If you look closely enough you can see an amoeba at the top left corner.
Second observation: Fungi isolation and viewing

This picture show many cells (probably yeast). They come from the mould of a piece of mouldy bread.
This shows a very interesting picture that has a few different types of cells.
Third observation: Staining of bacteria

i) Yogurt.

This picture shows what is observed when yogurt is run under crystal violet and put under a microscope.
This is a closer view of the yogurt specimen.
ii) Tooth swab

This shows the organisms found in Rayner's teeth.
Fourth observation: Hanging Drop

This shows what is observed under the microscope after the experiment is carried out.
A closer view of the bacteria.

Disorder in the Digestive System

1. Each group will be assigned a disorder in digestive system, in respect to each organ in the digestive system.

2. The disorders are:

a. Xerostomia

b. Peptic Ulcer

c. Gallstone Disease

d. Pancreatitis

e. Hereditary Colorectal Cancer

Digestion

http://kitses.com/animation/swfs/digestion.swf

Summary:

In Mouth:

- Salivary amylase breaks down starch into maltose.

In Stomach:

- Proteases break down proteins into peptides.

In Duodenum:

- Amylase breaks down any remaining starch into maltose.

- Maltose further broken down into glucose by maltase.

- Proteases break down proteins into peptides.

- Peptides further broken down into amino acids by proteases.

- Lipases break down fats into fatty acids and glycerol.

DNA Extraction at HOME!

Group: Rayner, Niklaus, Tim , See Toh, Johanan(Red Blood Cells

Organelle in Red Blood Cell are cytoplasm, cell membrane.

Cytoplasm - rich in hemoglobin, which is an iron-containing biomolecule that can bind oxygen and is responsible for the blood's red colour. It contains simple protein and iron pigment. It will turn redder when there is more oxygen.

Cell membrane - It aid in regulating their surface deformability, flexibility, adhesion to other cells and immune recognition. It also have three layers.

(Has no nucleus to maximize space to carry oxygen. Human red blood cells do reproduce by cell division. They are produced in the bone marrow. Immature erythrocytes have a nucleus but mature erythrocytes have no nucleus.)

Function of cell

-Controls pH. The pH of blood must remain in the range 6.8 to 7.4, otherwise it begins to damage cells.

- Transfer Oxygen to different parts of the body

- Transfer waste gas( carbon dioxide) to the lungs

Group: YuChong, Naveena, Cherin, Jun Wei, Benjamin, Min Suk

Question 1,2 & 3

1.Cell wall-protects the cell and regulates the life cycle of the plant organism.

2. Chloroplast-The most important characteristic of plants is their ability to photosynthesize, in effect, to make their own food by converting light energy into chemical energy. This process is carried out in specialized organelles called chloroplasts.

3. Endoplasmic recticulum-manufactures, processes, and transports chemical compounds for use inside and outside of the cell.

4. Golgi Apparatus-is the distribution and shipping department for the cell's chemical products. It modifies proteins and fats built in the endoplasmic reticulum and prepares them for export as outside of the cell.

5. Mitochondria-breaks down carbohydrate and sugar molecules to provide energy, particularly when light isn't available for the chloroplasts to produce energy.

6. Nucleus- Controls all activities in the cell.

7. Cell membrane-Controls the movement of substances into and out of the cell.

8. Vacuole-Each plant cell has a large, single vacuole that stores compounds, helps in plant growth, and plays an important structural role for the plant.

Root Hair Cell

Preston's Group

a) There are 5 organelles found in a root hair cell. The 5 organelles are the nucleus, plasma membrane, cytoplasm, vacuole and the cell wall.

b) The functions of the cell is to absorb water and mineral ions from soil. The projecting section has large surface area for absorption of water and minerals from soil water, there are no chloroplasts. The nucleus stores the DNA of the cell and it controls all the activities in the cell. Cellular activities takes place in the cytoplasm. The cell membrane controls the movement of substance in and out of the cell. It is a selectively permeable membrane because it allows only some substance to pass through. The large central vacuole is filled with a fluid (sap fluid: contain dissolved sugars and amino acid) and is surrounded by a sap membrane or tonoplast. It provides structural support and maintains turgor pressure. The cell wall gives the plant its shape and has a fully permeable structure (allows all substance to pass through).

c) Root hairs form an important surface over which plants absorb m

ost of their water and nutrients. They are also directly involved in the formation of root nodules in legume plants.

They have a large surface area, relative to the other cells, that helps them absorb water and minerals more efficiently.

Muscle Cell: By Jonan, Davina, Hardy, Jun Hong, Chris

Organelles present in the muscle cell: Mitochondria, Myofibrils, Nucleus, Golgi Apparatus, Endoplasmic Reticulum.

Functions: Release energy and initiate movement.

The purpose of muscle is to regulate/initiate movement (using Adenosine triphosphate aka. ATP), they have larger mitochondria's so to produce a larger quantity of ATP. To completely oxidize carbohydrates an organelle called Mitochondria is required and so muscle cells have many of these.

Specialised Cells Research

1. Students to research on one of the following cells assigned to you (e.g., root hair cell, green leaf cell, human muscle cell and human red blood cell), and get ready the following answers by next lesson.

Area of focus:
a. What are the organelles found in the cell?

b. What are the functions of these organelles?

c. Why are these functions of the organelles important to the living cell?
