Question
Hey, can i get help for my next week study guide just checking my answers. Thank you 1. What are the three components of the cell theory? 2. Of what is the cell membrane is mainly composed? 3. TRUE or FALSE: A prokaryotic cell has a nucleus. 4. TRUE or FALSE: An eukary cell does not have membrane otic bounded organelles. 5. Most organelles can be found in both in plants and animals. What three organelles are unique to plants? 6. What organelles can only be found in animal cells? 7. Which of the following contains digestive enzymes? 8. TRUE or FALSE: In most mammals, the DNA found in mitochondria is inherited from the mother only. 9. TRUE or FALSE: Flagella are not found on eukaryotic cells. 10. How do phospholipids interact with water to form the cell membrane? 11. TRUE or FALSE: All living things have a plasma membrane and a cell wall. 12. What is the first law of thermodynamics? 13. What is the example of potential energy that was given in the lecture notes? 14. What is the second law of thermodynamics? 15. What is entropy? 16. What is an exergonic reaction? 17. What is an endergonic reaction? 18. TRUE or FALSE: An enzyume is an organic molecule (usually a protein) that catalyzes a cellular reaction.Explanation / Answer
1. cell theory consists of
All known living things are made up of one or more cells.
All living cells arise from pre-existing cells by division.
The cell is the fundamental unit of structure and function in all living organisms
2. cell membrane is mainly made up of phospholipids and proteins.
3. false. because prokaryotes has nucleod. not nucleus.
4.false. eaukaryotes have mitochondra, ribosomes which are membrane bound.
5. palnts have organelles like chloroplasts, vacoule, and plastids which are unique and not found in animals.
6. animals have mitochindria, ribosomes, golgy comple, rough and smooth endoplasmic reticulum.lysosomes.nucleus etc.
7. true. mothers mitochndrial dna is transfered to offsprings in most mammals.
8. false. flagella is found in eukaryotes.
9. phospholipids are arranged as a lipid bilayer. where the hydrophillic head interact with water inside and outside and hydrophobic fatty acid tail is in the middle forming a layer around the cell.
10. false. pnly plants have cell wall. cell wall is absent in animal cell wall.
11. its also called a law of conservation of energy. energy is neither created nor destroyed.
