FC: Cell City! | By:Samantha Stokes,Adrian Flores,Jessica West,and Tyresha Gibbs
1: In Cell City there are two divisions; Animal Cell Drive and Plant Cell Place. We will take you on an amazing journey to learn about both sections.
2: First,lets' go to the control center and see the nucleus!It manages all cell activity and contains the DNA.It is located in the center of the cell in the animal cell and in the plant cell it is at the side of the cell. The nuclear pore is a protein-lined that regulates transcription between the nucleus and the cytoplasm.
3: What are chromosomes and chromatin? Chromosomes are packaged,thread-like structures made of proteins and nucleic acids that give an organism traits (hair color,size,etc.). Chromatin is the material the chromosomes are grouped inside the nucleus.
4: In animal and plant cells,the mitochondria has two different functions.In the animal cell,it is the power house,while in the plant cell,it breaks down sugars and carbohydrates if light isn't present for photosynthesis.
5: Golgi bodies are responsible for packaging proteins for the cell. Once the proteins are produced they go to the rough E.R.
6: Vacuoles in animal cells are small that help intracellular digestion and helps release waste products. In the plant cell,however,it stores water for producing rigidity in the plant.Without enough water, the pressure in the vacuole is reduced and the plant wilts.
7: The rough E.R.(endoplasmic reticulum) is responsible for the production of the protein and lipid components of most cell organelles. The smooth E.R. breaks down, detoxify the cell, transports and synthesizes membrane phosholipids.
8: Flagellum are whip-like structures in the cell and has usually one.It helps the cell move. | The cilium are tiny hair-like structures that help the cell move.It has more liquid around it and cleans it.
9: Centrioles are organelles that are only found in animal cells. They are responsible for cell division.
10: Lysosomes serves as the digestion system of the cell.It breaks downs obsolete material outside the cell and the components inside the cell itself.
11: Cytoplasm is the cell substance between the cell membrane an the nucleus. It contains cell organelles and various particles.
12: The plasma membrane is the barrier of the cell which is semi-permeable (only certain materials can enter the cell).It is located in the animal cell.
13: What if the cell doesn't have a cell membrane? | Every organelle in the cell would be out of place without proper security,we would not exist.
14: The cell wall is the defined boundary or wall that is part of the outer structure of the plant cell.It also supports the cell's rigidity .
15: What does the plasma membrane contain? | The plasma membrane is a bilayer composed of the following: Head-hydrophilic component which takes in water. Fatty acid tail-hydrophobic component which bounces water out. Carbohydrate-stabilizes the plasma membrane Cholesterol-chemical component which keeps the other fatty acid tails from sticking together. Membrane Protein-sends chemical signals to local cells for communication.
16: What is photosynthesis? | Photosynthesis is the process when carbon dioxide with sunlight and water into oxygen and sugars in the plant cell.
17: What is chloroplast and chlorophyll? | In the plant cell chloroplast is a specialized organelle that produces the chemical pigment chlorophyll(which gives the plant a green color).
18: Homeostasis is the state of equilibrium inside the body. Example:When you get sick,your body temperature rises to kill the micro-bacteria.
19: Diffusion is when particles go from high concentration to low concentration. Osmosis is the process of which water molecules go from high to low concentration. Example:The particles in a spray bottle are in high concentration.When you spray it,it goes to low concentration because the particles disperse.
20: Ribosomes are special organelles that are directly involved in protein synthesis.They are made of RNA (ribonucleic acid) and proteins.They then go out of the cytoplasm and into the cytoplasm to function.
21: How does the plasma membrane let things in and out? The phospholipids in the bilayer clump together with the part that is hydrophilic(head) pointing out and the hydrophobic(tail) is pointing in.
