The phloem tissue in plants is responsible for transporting sugar molecules, such as sucrose, from the leaves where they are produced through a system of sieve tubes to other parts of the plant. These sugar molecules are essential for providing energy for growth and metabolism in the plant.
Sugar molecules do not diffuse through a plant cell membrane because they are too large and polar to pass through the hydrophobic interior of the lipid bilayer. Instead, sugar molecules are transported across the membrane by specific transport proteins, such as sugar transporters, that facilitate their movement into the cell.
Passive transport does not require sugar. Passive transport is a process by which molecules move across a cell membrane without the input of energy, such as diffusion or osmosis. Sugar molecules can be transported passively, but the process itself does not depend on sugar.
The process by which molecules of sugar pass through an animal cell membrane is called facilitated diffusion. In this process, sugar molecules move across the cell membrane with the help of specific transport proteins. These transport proteins create channels for the sugar molecules to pass through, allowing them to replenish the cell's supply of sugar.

Plants store sugar mainly in the form of starch, which is a long chain of glucose molecules. They produce sugar during photosynthesis in their leaves and then transport it to other parts of the plant, like roots and stems, where it can be stored. This stored starch can be broken down into sugar later when the plant needs energy to grow or survive. It's like saving energy for a rainy day!
No, extra sugar molecules are transported out of the plant through specialized cells called phloem. Stomata are responsible for gas exchange, allowing carbon dioxide to enter and oxygen to exit the plant.
Plant sugar is "sucrose", made up of the simpler sugar molecules "glucose" and "fructose" (both produced by photosynthesis).
Active transport can transport both sugar and amino acids across the cell membrane. This process requires energy in the form of ATP to move these molecules against their concentration gradient.
The movement of sugar in a plant is called translocation. This process involves the transport of sugars like sucrose from the leaves, where they are produced through photosynthesis, to other parts of the plant for energy or storage.
