Our first homework! Recall that I take the homeworks for the marking period and count them as one test. That means you should have a 100% on this test. Certainly help the average!
This is posted on Monday and is due Friday. I will have it on hard copy (paper) if you don't have access to the computer. However, the hard copy will be availabe Tuesday. Still due Friday.
Use your book to get all these correct. Don't guess! If you have questions please ask.
This first homework we will do in class...so you all get 100%...if you pay attention.
Question #1: Cells are to tissues as organs are to:
1. organ systems
2. cells
3. genes
4. organelles
Question #2: Which sequence is listed in order from simplest to most complex?
1. tissue...cell...organ system...organ
2. cell...tissue...organ...organ system
3. cell...tissue...organism...organ
4. organism...tissue...organ...organ system
Question #3: Living things are made mostly of these four main elements:
1. hydrogen, oxygen, nitrogen, and protein
2. water, protein, carbohydrate, and fat
3. carbon, hydrogen, oxygen, and nitrogen
4. glucose, salt, mineral, and base
Question #4: Which structure is the boundry between a living cell and its environment?
1. cell membrane
2. cytoplasm
3. vacuole
4. ribosome
Question #5: The cell nucleus functions
1. in obtaining energy for the cell
2. in the storage of digestive enzymes
3. as the center of control for cell metabloism and
reproduction
4. in the transport of materials throughout the cell
Question #6 The genetic material of an animal cell is found in the
1. nucleus
2. cytoplasm
3. ribosomes
4. vacuole
Question #7 Current evidence indicates that ribosomes are most closely associated with
1. contraction of the cytoplasm
2. production of DNA
3. synthesis of protein
4. regulation of mitosis
Question #8 Mitochondria are organelles in which
1. digestive ensymes are stored
2. secretory products are packaged and stored
3. the energy needed by the cell is released from
nutrients
4. protein manufacture occurs
Question #9: Which cell organelles are most closely associated with energy changes in a plant cell?
1. mitochondria and chromosomes
2. chloroplasts and mitochondria
3. chromosomes and nucleus
4. chloroplasts and nucleus
Question #10: A scientist wanted to know whether the cells of a particular single-celled green algae could survive without any mitochondria. The scientist removed all of the mitochondria from hundreds of these cells. All of the cells died. Explain the most likely reason the green algae could not survive without mitochondria.
