cell structures are structurally different. There are many organelles are membranous‚ such as the nucleolus‚ endoplasmic reticulum‚ Golgi apparatus‚ vacuoles and vesicles‚ lysosomes‚ peroxisome‚ mitochondrion‚ and chloroplast. The unique structures between the two: plant cells- large central vacuole‚ cell wall‚ chloroplast; animal cell- small vacuoles‚ and centrioles. In the animal cell‚ they have many structures and functions: plasma membrane defines the cell boundaries and regulates molecule

Centriole- Aids in cell division and it’s only in animal cells. Lysosomes- Clean-up organelle it digests and breaks down lipids‚ carbs‚ and proteins. Nuclear Pore- Dots on the envelope which allows material in the and out of the

A mitochondrion (Terminologia histologica: Mitochondrion) is a cell organelle of eucaryotes with ovoid shape that is the major source for intracellular energy. Mitochondria are present in all but mature red blood cells. They can migrate through the cytoplasm and change their shape. These organelles have an outer unit membrane (membrana mitochondrialis externa) and an inner membrane (membrana mitochondrialis interna). The latter has protrusions into the matrix (mitochondrial plasma). Depending on

Comparing Cell Theory Parts to real world applications Cell Membrane compared to a house- Cellmembrane = screen on porch or window‚ lysosome is garbage disposal or recycling bin‚ vacuole is a water storage tank‚ er are hallways‚ mitochondria is a furnace or electrical generator‚ ribosomes could be the kitchen oven that’s making dinner‚ the nucleus is the parent Lysome- Cell Wall- probably be like a city wall surrounding the city‚ protecting it and defining the boundaries (osmotic control‚ protection

increased exposure to hormone-like chemicals in the environment. C) increased sperm motility from multiple flagella. D) decreased metabolic levels from overexposure to UV rays. Points Earned: 0.5/0.5 Correct Answer(s): B 16. Contractile vacuoles A) prevent cells from bursting as a result of the influx of excess water. B) help in the excretion of excess salt. C) are generally found in protists that inhabit salt water. D) allow organisms to avoid dehydration by absorbing water from the

to family just like the ER where proteins and lipids are being mad. 6. Centriole is like a CLOTHING RACK ... because Centriole organizes cell division and just like the clothing rack it organizes different sizes and clothes. 7. Lysosome is like a TRASHCAN ... Lysosomes are cellular organelle that contains acid hydrolase enzymes that break down waste materials and cellular debris‚ just like the trash can where we disposed our trash. 8. Cytoplasm is like FLOORS because the cytoplasm in a cell allows

keeps everything in control. He/she controls the functions and activities in a mall as well as a cell. Vacuole –The vacuole stores excess food‚ waste and other substances. In a mall this could be the storage room‚ storing signs or any excess mall materials‚ or it could be a garbage can‚ storing any excess waste that shoppers and employees produce. Lysosomes – The job of the lysosomes is to clean up the cell if it is damaged. Then recycle‚ patrol and kill invaders. In the mall‚ this would be
