All living organisms are composed of cells. Multicellular organisms (example: humans) are composed of many cells while unicellular organisms (example: bacteria) are composed of only one cell. Cells are the basic unit of structure in all organisms.
Answer:
Option (2), (3) and (4).
Explanation:
Charophytes are the group of some green algae of fresh water. The cahrophyta can be included in both the division and super division. Embryophyta has been emerged from the charophyta.
A student confirm whether the algae is charophyte or not by looking at the specific features. The cahrophytes has well defined sexual characters and the structure of sperm cell, the presence of phragmoplast confirms the charophytes. The cellulose synthesizing ring complex is also present in charophytes.
Thus, the correct answer is option (2), (3) and (4).
A. A chloride ion moves across the plasma membrane from a higher to lower concentration inside the cell.
Explanation:
Diffusion is the movement of particles from a region of higher concentration to that of lower concentration. Sometimes diffusion may require energy input to drive it.
- In facilitated diffusion, the concentration gradient creates the drive that fosters the diffusion.
- A membrane allows for the movement of tiny particles of matter across two regions.
- When the concentration in a region is above that of another, particles will move from the area having high concentration to that with a lower concentration till they both attain uniform concentration.
- This is known as facilitated diffusion.
