Animal cells have plasma membrane while plant cells have cell wall and cell membrane. A plant cell has 1 large vacuole while an animal cell has more than 1 vacuole which is smaller compared to the vacuoles of a plant cell. The vacuole of a plant cell is hypertonic because it takes up to 90% of the cells volume. A plant cell has chlorophyll or chloroplasts (which gives colors to plants), animal cells does not have chloroplasts. Cell division is also called mitosis (this term is used for both animal and plant cells, no difference on that). For plant cells, centrifugal division occurs, its starts in the middle going outwards creating the cell plate. For animal cells, division is centripetal that it comes from the outside going toward the center and that is called the cleavage furrow.

Answer from: Quest

im gonna compare the cells to jobs in factory. give brainliest

job in the factory // cell organelle //

shipping/receiving

department plasma membrane

chief executive officer// nucleus

factory floor // cytoplasm

assembly line// endoplasmic reticulum

workers in the assembly line //ribosomes

finishing/packaging department //golgi apparatus

maintenance crew //lysosomes

support beams (walls, ceilings, floors) //cytoskeleton

power plant //mitochondria/chloroplasts

here's what each part of the cell does:

plasma membrane :

regulates what enters and leaves the cell; where cell makes contact with the external environment

nucleus :

controls all cell activity; determines what proteins will be made

cytoplasm :

contains the organelles; site of most cell activity

endoplasmic reticulum:

where ribosomes do their work

ribosomes :

build the proteins

golgi apparatus :

prepares proteins for use or export

lysosomes :

responsible for breaking down and absorbing materials taken in by the cell

cytoskeleton :

maintains cell shape

mitochondria/chloroplasts :

transforms one form of energy into another
