Cell Parts(Organelles, Plasma Membranes)

Julia Cochrane, Gabriel Bloch, Jenna Ku, Jim Yu

NucleusIn what type of cell: Both animal and plantLocation: Center of the cellFunction: Serves as an information and administrative center for the cell

NucleolusIn what type of cell: Both animal and plantLocation: Center of the NucleusFunction: Organelle in eukaryotic cell nucleus that produces ribosomes.

Cell WallIn what type of cell: PlantLocation: Outermost part of the plant cell.Function: To provide support and protection for the cell.

Plasma/ Cell MembraneIn what type of cell: Both animal and plantLocation: Outer most part of animal and inside the cell wall of the plant cell.Function: Regulates what enters and leaves the cell, and also provides protection and support.

ChloroplastIn what type of cell: PlantLocation: Near nucleusFunction: Captures energy from the Sun and converts it into chemical energy in a process called Photosynthesis.

CytoplasmIn what type of cell: Both animal and plantLocation: Throughout the cellFunction: Clear, gelatinous fluid that suspends the cell’s organelles.

Endoplasmic ReticulumIn what type of cell: Both animal and plantLocation: Around the nucleusFunction: Modifies proteins and lipids (smooth has no ribosomes, rough has ribosomes attached)

CytoskeletonIn what type of cell: Both animal and plantLocation: Within the cytoplasm Function: Cellular framework composed of microtubules and microfilaments.

MitochondriaIn what type of cell: Both animal and plantLocation: Near cell membraneFunction: Power generator for the cell

LysosomeIn what type of cell: Both animal and plantLocation: Throughout the cytoplasmFunction: Organelle that contain digestive enzymes; digest excess or worn out organelles, food particles, and engulfed viruses or bacteria.

Golgi ApparatusIn what type of cell: Both animal and plantLocation: close to the endoplasmic reticulum

and nucleus.Function: The distribution and shipping

department for the cell’s chemical products

RibosomeIn what type of cell: Both animal and plantLocation: Throughout the cytoplasmFunction: Protein production sites

VacuoleIn what type of cell: Both animal and plantLocation: In a plant cell, the vacuole is very

prominent in the center. In an animal cell, there are multiple vacuoles throughout the cell.

Function: Membrane-bound fluid-filled space in the cytoplasm for temporary storage of materials.

Structure of Plasma MembranePhospholipids• Lipids with a phosphate group attached

Carrier Proteins• Allows larger substances to move through the plasma membrane

Cholesterol Molecule• Helps stabilize the phospholipids• Prevents fatty acid chains of the phospholipids from sticking

together.

Polar Head

Nonpolar Tail
