front 1 How big are cells generally? | back 1 0.1-0.5 micrometer |
front 2 Are prokaryotic or eukaryotic cells bigger? | back 2 Eukaryotic becuase they contain more organelles than prokaryotic cells |
front 3 Why does Cell growth is limited? | back 3 Becuase volume of cells increase way more compared to surface area eventhough more surface area means more area for food absorption but it still isn't sufficient for the volume you need to feed |
front 4 What is Cell theory? | back 4
|
front 5 What is the bacteria cell wall made of? | back 5 Sugars and Amino acids |
front 6 What is the function of the Capsule of prokaryotic cells? | back 6 To make the prokaryotic cell able attach to its environmental surfaces |
front 7 What is the role of pilis in prokaryotic cells? | back 7 To transform genetic materials during conjugation(sexual reproduction of bacteria) |
front 8 What does the word eukaryotic mean? | back 8 True nucleus |
front 9 What does the word organelle mean? | back 9 Little organ |
front 10 What is the function of Cholesterol in plastmatic membrane of cells? | back 10 To regulate fluidity in between the phospholipid bilayer, to not let the two layers get so close to each other when its cold snd vice versa |
front 11 What is the Fluid-moasic model? | back 11 A model to explain the structure of the plasmatic membrane of the cell, that is consist of fluid(cholesterol) +moasic(phospholipids, proteins and Carbohydrates)(moasic simply are an art made from small stones) |
front 12 What is the funcion of Protones in Nerve cells? | back 12 To transform impulses |
front 13 Name the types of proteins in the plasmatic membrane of cells based on their function. | back 13
|
front 14 Explain the function of transport proteins? | back 14 Transporting things either by:
|
front 15 What do channel proteins(pores) transport? | back 15 Lipids(like triglycerides[which is one of the components of ATP]), insoluble substances, ions(like K+,Na+ and Cl- just like how nerve cells use to transport pulses) |
front 16 What do receptor proteins do? | back 16 They bind to hormones to initiate biochemical reactions |
front 17 What do Attachment proteins do? | back 17 Support the cytoskeleton to hold the shape and structure of the cell |
front 18 What do recognition proteins do? | back 18 For cells to recognise each other, just like how red blood cells recognise each other |
front 19 Name examples of recognition proteins? | back 19 Glycoproteins, although they aren't proteins but Glycolipids |
front 20 What do intercellular junction proteins do? | back 20 Provide space between cells wether its:
To allow substance transform and enough space so if one cell is infected it'll stay away from the other cells |
front 21 What are microvilli? | back 21 Finger like structures made of folding the plasmatic membrane |
front 22 What is the use of Microvilli? | back 22 They increase the surface area of cells so that they have more places to absorb substances from |
front 23 What is celiac disease? | back 23 Its when the microvilli of the small intestine get flattened so they can't absorb the gluten proteins in bread |
front 24 Where are microvilli found? | back 24 Small intestine |
front 25 What is the function of Carbohydrates in the plasmatic cell membrane? | back 25 They decorate proteins(to make glycoproteins) and lipids(to make glycolipids) so that cells can recognise each other |
front 26 What is the function of Plasmatic membrane? | back 26
|
front 27 What are the types of passive transport? | back 27
|
front 28 What is diffusion? | back 28 Transporting of substances from high concentration to low concentration to achieve homeostasis |
front 29 What is osmosis? | back 29 Is what you call diffusion but only for water |
front 30 What substances are transported by diffusion? | back 30
|
front 31 What is Tonicity? | back 31 the ability of a solution to change cell volumes by changing their water content |
front 32 What are the types of tonicity? | back 32
|
front 33 What are the types of Active Transport? | back 33
|
front 34 What are the types of Endocytosis? | back 34
|
front 35 What is Phagocytosis? | back 35 Know also as cell eating, which is when cells dissolve bacteria in them |
front 36 What is the importance of active transport? | back 36
|
front 37 What is the function of Vesicles? | back 37 Created by the golgi apparatus to Bulk transport macromolecules in and out of cells including:
|
front 38 What do Macrophages do? | back 38 They are part of the immune system, that dissolve bacteria and old red blood cells in them |
front 39 What is Pinocytosis? | back 39 Also called cell drinking, which is when cells absorb liquid and/or small molecules dissolved in liquid, just like the intestine, kidneys and plant roots |
