Endoplasmic Reticulum and Mitochondria
Endoplasmic Reticulum:
- Rough- pebbled shape
- endoplasme retoidem is collected and transported through the cell
Smooth- it has bound vesicles and tubules
- it breaks down of lipid-soluble and controls calcium releases
- in animal and plant cells
Mitochondria:
- has a double membrane
- its outer layer is smooth but that inner layer is convoluted
- it provides energy a cell needs and the power at the center
- in animals and plant cells
Nucleus and Ribosomes
Nucleus:
- The nucleus is the brain of the cell which controls everything within the cell. DNA is stored in in the nucleus.
- are in animals and plant cells
Ribosomes:
- The ribosomes carry out proteins of synthesis for the nucleus. It brings together things such as RNA and amino acids to make proteins.
- There is a small and large subunits
- are in animals and plant cells
Cell Membrane and Cytoskelton
Cell Membrane:
- cell membranes surround the cell and regulate substances that enter and exit.
- These membranes also protect the inner cell from outside forces
- are in both animal and plant cells
Cytoskeleton:
- makes up the internal framework
- It is important for cell movement and cell division
- are in both animal and plant cells
Cytoplasm and Golgi Apparatus
Cytoplasm:
- semi-fluid substance inside the cell.
- The cytoplasm encases and cushions and protects the internal organelles.
- in both animals and plant cell
Golgi Apparatus:
- used for shipping goods created by the ER and ribosomes to the rest of cell.
- are in animal and plant cells
Chloroplast and Lysosomes
Chloroplast:
- they use sunlight to create energy for the city.
- only found in plant cells
Lysosomes:
- digestive sacs that can break down macromolecules in the cell using the process of hydrolysis.
- help keep excessive or bulky macromolecules from building up in the cell
- found in animal and plant cells
Vacuole and Peroxisomes
Vacuole:
- Hold many substances from organic molecules to simple excess water
- Plant cells have a central vacuole that is important in maintaining plant turgidity
- found in both animal and plant cells
Peroxisomes:
- converts fat into sugar and uses it in chloroplasts
Centrioles and Nucleolus
Centrioles:
- ring of 9 groups of fused microtubules
- 3 microtubules in each group
- found in animal cells
Nucleolus:
- provides ribosomes, which moves the nucleus and take positions on rough endoplasmic reticulum where they are critical in the protein synthes
Chromatin and Nuclear Membrane
Chromatin:
- package DNA into a smaller volume to fit in the cell
- found in both animal and plant cell
Nuclear Membrane:
- separates the fluids inside the nucleus, from the fluids outside the nucleus.
- double-layered membrane
- Found in both animal and plant cells
