Answer 2

Explanation:

➡️ Uniport - It is one sided movement of a substance through the cell membrane independent of other solutes.

➡️ Symplast - It is simultaneous movement of two or more solutes across cell membrane in the same direction.

➡️ Antiport - It is simultaneous movement of two solutes in opposite direction across the cell membrane.

▶️ Uniport, symport and antiport are types of facilitated diffusion which does not require energy. Similar type of passage also occur in case of active transport where energy is required.

Hope it helps!!✌️
