List the typical organelles of an animal's Eukaryotic cell
|
1. Cell membrane
2. Cytoplasm (not an organelle) 3. Nucleus 4. Nucleolus 5. Mitochondrion (singular of mitochondria) 6. Ribosome 7. Lysosome 8. Rough endoplasmic reticulum 9. Smooth endoplasmic reticulum 10. Golgi apparatus 11. Vacuole 12. Centrioles |
|
|
Which of those organelles are membrane-bound organelles?
|
1. Nucleus
2. Mitochondria 3. Lysosomes 4. Endoplasmic Reticulums 5. Golgi Apparatus 6. Vacuoles |
|
|
What function does a plant (and some bacteria, protist and fungi) cell's cell wall have?
|
The cell wall is a rigid layer of non-living material. It:
Provides protection and support especially when the cell vacuole has little water. |
|
|
What does a cell membrane do?
|
A cell membrane controls what enters and leaves cells, by having a phospholipid bilayer and protein channels. It is responsible for
1. Filtration 2. Adhesion 3. Communication between cells 4. Recognition between cells |
|
|
What is the cytoplasm?
|
A jelly like substance inside cell membranes that the organelles are suspended in.
|
|
|
What is the cytoskeleton?
|
It is made of microtubules and gives cells without cell walls their shape.
|
|
|
What is the function of the nucleus?
|
The nucleus contains DNA and the nucleolus. The DNA is found on chromatin strands.
The nucleus controls production of proteins needed by the cell or organism. Materials pass through the nuclear membrane. |
|
|
What does the nucleolus do?
|
The nucleolus is part of the nucleus.
The nucleolus creates ribosomes during protein synthesis. |
|
|
What is the nuclear envelope?
|
The nuclear envelope surrounds the nucleolus and DNA, protecting them.
The pores in the membrane filter materials by dimension, allowing water soluble molecules into the nucleus. |
|
|
What is the function of ribosomes?
|
The ribosomes are created in the nucleolus, and found suspended in the cytoplasm or on the Rough endoplasmic reticulum.
They produce proteins as directed by the nucleus. |
|
|
What is the endoplasmic reticulum and what does it do?
|
The endoplasmic reticulum carries proteins and other materials to the golgi apparatus. It contains enzymes important for metabolism.
|
|
|
What does the golgi apparatus do?
|
The golgi apparatus or body is made up of flattened sacs. It receives proteins and other materials and 'packages' them up in vacuoles and then 'ships' them out.
|
|
|
Describe the function of mitochondria
|
Mitochondria are rod-shaped membrane-bound organelles that release energy from glucose.
They have folded insides that create larger surface area for release of energy. |
|
|
What are centrioles?
|
Centrioles play a role in organising genetic material during cell division.
|
|
|
What is the chloroplast's function?
|
Chloroplasts are membrane-bound organelles found only in plant cells. They turn light energy into chemical energy for cell consumption.
|
|
|
What do vacuoles do?
|
Vacuoles store water and other materials in the cell.
They transport materials between cells also. They are small in animal cells, and very large in plant cells. They work along with the cell wall in plant cells to keep the plant upright. |
|
|
What is the function of lysosomes?
|
Lysosomes contain enzymes which digest dead cell parts and food.
