Question

cell transport date cell transport - movement of molecules in and out of the cell match the definition on the left with the term on the right. 1. __ large wastes or cell products are released from inside to outside a cell 2. diffusion of water molecules through a selectively permeable membrane. 3. the transport of particles which requires the use of energy 4. a state reached when particles continue to move but in equal amounts in and out of the cell. 5. large particles are surrounded by the membrane and taken into the cell. 6. movement of any particles from an area of higher concentration to one of lower concentration, with the concentration gradient. 7. __ the transport of particles which does not require energy a. passive transport b. diffusion c. dynamic equilibrium d. exocytosis e. osmosis f. active transport g. endocytosis circle the word or phrase that best completes the statement or answers the question. 8. the structure most responsible for maintaining cell homeostasis is the cytoplasm cell wall mitochondria plasma membrane 9. the plasma membrane (cell membrane) is made up of a(n) cholesterol layer enzyme layer phospholipid bilayer protein layer 0. which of the following is not a form of passive transport? facilitated diffusion diffusion endocytosis osmosis. diffusion continues until uilibrium is reached turgor pressure is reached one side has more if a cell is placed in salt water, water leaves the cell by nosis diffusion active transport phagocytosis a cell moves particles from a region of low concentration to a region of high concentration by tated diffusion osmosis passive transport active transport illustrate the movement

Explanation:

Matching Questions (1 - 7)

1. Explanation for 1: Exocytosis is the process of releasing large wastes or cell products from inside to outside the cell. So match with d. Exocytosis.
2. Explanation for 2: Osmosis is the diffusion of water molecules through a selectively permeable membrane. So match with e. Osmosis.
3. Explanation for 3: Active transport requires energy for the transport of particles. So match with f. Active transport.
4. Explanation for 4: Dynamic equilibrium is when particles move in equal amounts in and out of the cell. So match with c. Dynamic equilibrium.
5. Explanation for 5: Endocytosis is when large particles are surrounded by the membrane and taken into the cell. So match with g. Endocytosis.
6. Explanation for 6: Diffusion is the movement of particles from higher to lower concentration (down the concentration gradient). So match with b. Diffusion.
7. Explanation for 7: Passive transport does not require energy for particle transport. So match with a. Passive transport.

Multiple - Choice Questions (8 - 10 and others)

1. Explanation for 8: The plasma membrane (cell membrane) regulates what enters and exits the cell, maintaining homeostasis. Cytoplasm is the cell's interior, cell wall (in plant cells) provides structure, mitochondria produce energy. So the answer is plasma membrane.
2. Explanation for 9: The plasma membrane is made of a phospholipid bilayer (with proteins and cholesterol embedded). Cholesterol layer, enzyme layer, and protein layer are incorrect. So the answer is phospholipid bilayer.
3. Explanation for 10: Passive transport includes diffusion, osmosis, and facilitated diffusion. Endocytosis is active transport (requires energy). So the answer is endocytosis.

Answer:

s:

1. d. Exocytosis
2. e. Osmosis
3. f. Active transport
4. c. Dynamic equilibrium
5. g. Endocytosis

7. a. Passive transport
8. plasma membrane
9. phospholipid bilayer
10. endocytosis
