Question

1. Name 3 Places in an animal and plant that active transport takes place.
2. What happens to an animal cell in a concentrated (hypertonic) and dilute (Hypotonic) solution?
3. What happens to a plant cell in an concentrated and dilute (hypertonic) solution?

Answer 1

Answer:

1. Active transport is the process by which materials move from a lower concentration to a higher concentration. Using adenosine triphosphate (ATP, needed for cellular energy) from respiration, molecules can move from one side of a cell wall to another. Keep reading to find examples of active transports in both plants and animals.

2. Most biological membranes are more permeable to water than to ions or other solutes, and water moves across them by osmosis from a solution of lower solute concentration to one of higher solute concentration. Animal cells swell or shrink when placed in hypotonic or hypertonic solutions, respectively.

3. If you place an animal or a plant cell in a hypertonic solution, the cell shrinks, because it loses water ( water moves from a higher concentration inside the cell to a lower concentration outside ).

Explanation:

• Some examples of active transport in plants include:
• Ions moving from soil into plant roots
• Transportation of chloride and nitrate from the cytosol to the vacuole
• Sugars from photosynthesis moving from leaves to fruit
• Calcium using energy from ATP to move between cells
• Minerals traveling through a stem to various parts of the plant
• Water moving from plant roots to other plant cells via root pressur
