Yes they are vascular like other gymnosperms
Explanation:
Rock fragments squeeze together
Active transport requires that the cell move engegy that it has obtained the food to move the molecule threw the cell membrane.The passive transport doesn't required as much energy for the molecule to move....
Answer:
b- It is a spontaneous process.
Explanation:
Passive transport is the type of transport of substances across the plasma membrane that occurs without energy expenditure and occurs spontaneously. There is no energy expenditure during passive transport because substances naturally move from the more concentrated to the less concentrated medium, ie in favor of the concentration gradient.
Substance transport occurs until concentrations inside and outside the cell are equalized.
According to this conceptualization we can conclude that the correct answer to your question is the letter B.
