membrane package
Unwanted substances could get in, potentially destroying the cell and membrane.
Golgi body
The organelle responsible for packaging substances inside the cell is the Golgi apparatus. It receives proteins and lipids from the endoplasmic reticulum, modifies them, and packages them into vesicles for transportation within the cell or outside of the cell.
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
membrane package
The Cell membrane on a plant cell is used to allow some substances into the cell (for nourishment) while keeping other (harmful or unwanted) substances out.
Unwanted substances could get in, potentially destroying the cell and membrane.
Inside of a cell it is the cell membrane which lets substances pass into the cell, and out. The cell wall is used to keep the shape of the cell the same.
Cell Membranes transport substances between the environment around the cell and inside the cell.
Rough ER
Golgi body
The organelle responsible for packaging substances inside the cell is the Golgi apparatus. It receives proteins and lipids from the endoplasmic reticulum, modifies them, and packages them into vesicles for transportation within the cell or outside of the cell.
The main job of the cell responsible for controlling which substances enter and leave a plant cell is the cell membrane. It acts as a selectively permeable barrier, allowing nutrients and other essential substances into the cell while keeping unwanted substances out. Additionally, the cell membrane also helps maintain the cell's internal environment by regulating the movement of molecules.
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
The primary substances responsible for making cell walls tough are cellulose, hemicellulose, and pectin. These substances provide structural support and rigidity to the cell wall, helping to maintain the shape and integrity of the cell.
