Introduction Genetics: the science‚ which deals with the principles of heredity and variation. Heredity: transmission of characters from parents to their off spring. Variation: Differences for various characters among the individuals of the same species. Types of variation: 1. Environmental and 2. Hereditary 1. Heredity variation: Variation observed among the individuals of the same species due to difference in their genetic constitution is termed as heredity variation. 2. Environmental variation:

Damn Near Everything There Is To Know About Cells: Biology Cell Report There are many parts of a cell‚ they all have specific duties‚ and are all needed to continue the life of the cell. Some cells exist as single-celled organisms that perform all of the organism’s metabolism within a single cell. Such single-celled organisms are called unicellular. Other organisms are made up of many cells‚ with their cells specialized to perform distinct metabolic functions. One cell within an organism may

Nucleus- The nucleus is the control center of the cell. This is where DNA is contained. This is like the town hall or the mayor’s office because it is the control center of a town. The nucleus uses DNA like a city uses blueprints to direct the production of protein. Nucleolus- The nucleolus is where ribosome is made and is rich in RNA content. It is located inside the nucleus. A mayor is like this because the mayor makes everything in the town happen. He also works from the town hall‚ or works

like the nucleus‚ vacuoles‚ the endoplasmic reticulum (ER)‚ vesicles‚ and the cell itself. It is because of the unique properties of the phospholipid bilayer that vesicles are able to so easily fuse with the Golgi apparatus and the plasma membrane‚ If not for these properties the endomembrane system would not function. The structures (organelles) that make up the endomembrane system are: The nuclear envelope‚ The rough and smooth ER‚ the Golgi apparatus and Golgi bodies‚ lysosomes‚ various vesicles

Have you ever wondered what living things are made up of? If you answered cells‚ then you’d be correct. A cell is the smallest thing that can be alive‚ and all living things are made of cells! Cells are made of tiny organelles that work together to help the cells live‚ just like organs in our body keep us alive. You must also remember that there are two types of cells. Eukaryotic and Prokaryotic. The differences are simple; Eukaryotic cells are more complex and have more organelles while Prokaryotic

we have to make sure the Golgi bodies are on time to. Furthermore we will be heading over to the lysosomes and the vacuole‚ which need each other for their task to succeed. The lysosomes is a recycler it recyclers all the burnt lumber or the extra waste found around the city‚ but if some waste can’t be recycled then where is the waste suppose to go? Well the waste will go to the vacuole which is the

also translucent to the eye and holds proteins. The contractile vacuole envelops water and food. Round in shape it can expand and contract to pull in nutrients. It has a condensation membrane on the inner side surrounded by endoplasm‚ accessory vacuoles‚ and mitochondria. The accessory vacuole aids in the formation of the main vacuole. The food vacuoles hold the nutrients and digest the intake. Lysosomes surround the food vacuoles and eliminate waste within the amoeba. The uroid excretes the waste
