Transcript of Cell Process

The Life Process of a Cell By: Nandhitha Ramasekaran, P-7, 11/16/12 Chapter 1: Daisies Discovery Chapter 2: Cell Discovery The following day, Daisy was walking through a meadow. While she was walking, she saw a dandelion giving off its petals. She didn't realize it at first, but a couple days later, she saw dandelions where the petals had landed... " This means all living things reproduce in some way,''she said. Chapter 3:
The Microscope Daisy's birthday was just a day away and she was really excited. On her B-day, her parents got her a microscope. With that, she started examining different things like a blade of grass or a piece of animal skin. What she saw was really amazing! Daisy saw all the cells moving around with their flagella. " All living things have cells,'' shouted Daisy. Chapter 4: Stimulus The days slowly turned to winter and Daisy fell sick. She had the flu. All she could do was stay inside and sleep. She had no energy to move. Daisy's petals all wilted. This means all living things must have energy to live. Chapter 5: DNA Strands One day, Daisy was playing with her microscope. While she was playing with it, Daisy saw some strand like things, it was DNA. She got really excited and examined more things. She realized all living things have DNA. She was really excited!!! Chapter 6:
The Sunflower One day, Daisy was walking through the meadow. While she was strolling, she saw a fly landing in a Venus flytrap. "The fly must have triggered the flytraps senses. Then the flytrap must have digested it,that means all living things have stimulus!'' she thought. Once there was a plant named Daisy. Daisy was very curious about life and always wanted to be a scientist. A few days later she was observing a tree. At first it was just a tiny plant, then it grew larger and larger and started bearing fruit till it was an huge apple tree. At that moment, Daisy realized that all living things grow and develop. Passive transport: Passive transport is the movement of particles across the cell membrane without the use of energy. The two types are diffusion and osmosis. Diffusion is the the movement of particles from high to low concentration. Osmosis is the diffusion of water through the cell membrane. Active Transport Active transport is the movement of substances across the cell with energy. The two types are endocytosis and exocytosis. Endocytosis is when a particle enters the cell. Exocytosis is when a large particle exits the cell. How Cells Make Energy Daisy had a test tomorrow and she had to study!
For her test, she needed to know how cells make energy. Plant cell make energy by taking water, sunlight, and carbon dioxide, putting it into the chloroplast, and oxygen and glucose will come out. Animal cells make energy by taking in glucose and oxygen, putting it in the mitochondria, and giving out water, ATP, and carbon dioxide, Flower Dandelion microscope lightning DNA Venus Flytrap Active Transport Science Textbook Science Textbook Science Textbook Science Textbook Science Textbook Science Textbook Science Textbook Science Textbook
and worksheet Science Textbook How Cells Reproduce Daisy, the flower, had another quiz on Friday! She was not prepared. she had to learn about binary fission, mitosis, and meiosis. Daisy started studying as soon as she got home. she remembered in school that binary fission occurred in prokaryotic cell and that it is cell division in bacteria. When it finished each cell has a copy of DNA. Mitosis and Meiosis Mitosis is in the eukaryote cells. Its the cell division that forms two nuclei with the equal amount of chromosomes. Meiosis also happens in eukaryote cells. Its the cell division when the number of the chromosomes decrease to the half of the original, by the two divisions of the nucleus. This results as sex cells. Cells Grow and Develop The next day in school Daisy was learning about how cell grow and develop(cell cycle)."The cell first goes through the inter phase; that's when the cell grows and copies its organelles,... Daisy, can you tell me what the second stage is?''said the teacher "The next stage is the chromatids. In that stage, 2 nuclei are formed with the same amount of chromosomes,'' answered Daisy."Good job!'' said the teacher."Lastly, then comes the centromere, this is when the cytoplasm splits and two cells are formed Binary Fission Science Textook Cell Division Science Textbook Cell Cycle Cell Process Notebook This book is about a plant, named Daisy who is very curious about everything. She learns everything from the cell process to the characteristics of life. Come read the book! Nandhitha Ramasekaran
