Plants get taller because they are stretching in search of sunlight. Sunlight is essential for photosynthesis; which energy, light, sunlight, water, carbon dioxide come together to produce sugar for the plants to survive.
Correct answer: B). With fewer contractions
The main function of a contractile vacuole is to maintain the sufficient amount of water in the protoplasm of the cell. For the freshwater amoeba contractile vacuole is needed to pump water and maintain a osmoregulation.
But when it is kept in sea water, more contraction is required to expel the water out of the cell in order to make the environment inside amoeba same as of sea water.
The directed movement of substances, into, out of or within a cell, either in a vascular tissue or in the vascular membrane.
The main roles of plant stems and roots are to transport substances around the plant. They have two types of transport systems – xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.
hope it helps because there is not any issue of transport , and if my answer i s not supportable comment i will provid emore information.
Answer:
The cell will swell.
Explanation:
The cells react distinctly when placed in different solutions like hypertonic, isotonic and hypotonic solutions. In the mentioned question, that is, in the fluid surrounding the cells, the concentration of salt reduces, which makes the solution hypotonic. Hypotonic solution exhibit high water potential and low solute concentration.
This makes the water move from the hypotonic solution to the inside of the cell as the osmotic movement occurs from high solvent concentration to low solvent concentration, thus, swelling of the cell takes place.
