Cell Parts Actual Test Flashcards
Describe the characteristic pf mitochondria that makes them well suited for their role
They have double membrane that helps them build up different concentration gradients
Cells of the stomach lining have large numbers of ribosomes and Golgi explain
They need many enzymes to they to manufacture and distribute them
How does a cell membrane differ from a cell wall
Cell membrane is made of phospholipids and cell wall is made of cellulose, rigid and only in plants
What does the rough Er have attached to it
Ribosomes
What organelles are only found in plants and what are only found in animals
Chloroplast and cell Walls
Centrioles
Water moves into a cell in a — solution
Hypotonic
Water moves out of a cell if the cell is placed in a — solution
Hypertonic
If cells are placed in a strong sugar solution water will
Move out of the cell
A cell moves particles from a region of lesser concentration to greater concentration by
Active transport
If a tulip is not watered or wilts because
The vacuole loses water
If a cell is placed in salt water, water leaves the cell by
Osmosis
Facilitated diffusion
Diffusion through a channel protein
Endocytosis
Active transport bringing substances into the cell
Exocytosis
Getting things out of cell using energy
Phagocytosis
Moving food into your cell using energy
Pinocytosis
Moving liquid into your cell using energy
Lysis
When cell explodes because water moves into cell (towards hypertonic)
Plasmolysis
When the cell shrinks due to water moving out of the cell
Hypertonic
More solute than solvent
Isotonic
Both sides equal
Hypotonic
Less solute than solvent
Diffusion
Passive transport of substances not water, from high to low concentration
Osmosis
The diffusion of water
Structure responsible for homeostasis
Cell membrane
Movement of particles from high concentration to low
Diffusion
Cellular eating
Phagocytosis
Movement of food particles into the cell using energy
Endocytosis phagocytosis
Loss of water from a cell resulting in a drop in turgor pressure
Plasmolysis
Diffusion of water molecules through a selectively permeable membrane
Osmosis
Release of wastes or cell products from inside to outside of a cell
Exocytosis
Active transport differs from passive
Active moves against the gradient ad they require energy to do so
Where is all the cellular energy needed for the cell made and how is it stored
Made in the chloroplast and it is stored in glycogen and starch
What do carbohydrates break down to
Monosaccharides
Lipids break down to
Fatty acids
Proteins break down to
Amino acids
Nucleic acids break down to
Nucleotides
What are two types of membrane proteins and what are their functions
Channel proteins: facilitated diffusion
Transport proteins: active transport or large molecules
When a lysosomes collides with a food vacuole what happens
They would digest the food in the vacuole
What packages materials for removal from the cell
Golgi body
How do materials get passed out of cell
Exocytosis
What contains identification markers for other cells
Cell membrane
In the final phase of completion, proteins are modified by special enzymes in what organelle
Golgi apparatus
What produces ATP
Mitochondria
Cell membranes are mostly composed of
Proteins and lipids
What structure is the site of protein synthesis
Ribosomes
What are found in every living cell
Cell membrane and ribosomes
What factors increase the Rate of diffusion
Distance, concentration of substance, and weight of molecules
Why is surface area to volume ratio important for cells
The ratio must remain small for the transport of molecules
