Cell structures & Functions Animal Cell Bacterial Cell Plant Cell

Organelles Structures that carry out a specific activities in the cell. Found in the cytoplasm

Cell membrane Location: Surrounding the cell Function: Controls the movement of materials into and out of the cell “Selectively permeable” Made of proteins and phospholipids

Cytoplasm Location: most of cell Function: jelly like substance that provides support for organelles, and a place for reactions to occur.

Nucleus Location: center of cell, bound by the nuclear membrane. Function: controls the normal activities of the cell. Contains chromosomes!

Nucleolus Location: inside Nucleus Function: makes ribosomes.

Ribosomes Location: cytoplasm, and on the Rough ER Function: structure on which proteins are made.

Endoplasmic Reticulum A highly folded membrane used to move proteins through the cell. Two types: Smooth ER lacks ribosomes Rough ER has ribosomes on its surface

Can you tell rough ER from smooth ER?

Golgi Apparatus Flattened membrane bound sacs Function: packaging and distribution center -Contains enzymes that modify proteins received in vesicles from the ER. -Then repackaged in new vesicles to be shipped out

Lysosome Small, spherical vesicles Function: Contains cells digestive enzymes Breaks down foods, and worn out cell parts

Mitochondria Function: harvests energy from organic compounds to make ATP (energy) Has its own DNA and ribosomes Primitive prokaryotes are the ancestors of mitochondria

Cytoskeleton Made up of Microtubules & Microfilaments Function: Structure & support

Plant Cells

Chloroplast Function: photosynthesis - traps sunlight to make sugars (food) Contain green pigment called chlorophyll

Vacuole Function: stores compounds such as sugars, proteins, minerals, wastes, & pigments, maintains cell structure (turgidity) Large single central vacuole

Cell wall Function: Gives shape to cell, protection, support, prevents excess water entry & “Lysing” Made of cellulose, very rigid Outside cell membrane

Differences between plant cells and animal cells Smaller in size Irregular shape Nucleus in center No cell wall Vacuole small or none at all No chloroplasts Plant Cell Larger in size Regular shape Nucleus against wall Cell wall Single large Central vacuole Chloroplasts
