Cell Organelles

Cell Organelles= “little organs” Different cells have different amounts of them depending on cell

Cell Organelles= “little organs” Different cells have different amounts of them depending on cell function They are suspended in a liquid called cytoplasm

Cell Membrane Boundary of cell Can control what enters or leaves cell Made of

Cell Membrane Boundary of cell Can control what enters or leaves cell Made of phospholipid bilayer and protein “gates”

Nucleus Control center of cell Contains DNA in the form of chromosomes Surrounded by

Nucleus Control center of cell Contains DNA in the form of chromosomes Surrounded by a nuclear membrane Usually one per cell

Cytoskeleton Made of “microtubules” Acts as skeleton and muscle creates shape and structure Helps

Cytoskeleton Made of “microtubules” Acts as skeleton and muscle creates shape and structure Helps move organelles around the cell

Endoplasmic Reticulum A. k. a. “ER” Transport “Highway” of the cell Rough ER: studded

Endoplasmic Reticulum A. k. a. “ER” Transport “Highway” of the cell Rough ER: studded with ribosomes; it makes proteins Smooth ER: no ribosomes; it makes lipids

Ribosome Make protein Found attached to rough ER or floating free Produced by the

Ribosome Make protein Found attached to rough ER or floating free Produced by the nucleolus (the dark spot in the nucleus) That looks familiar…what is a polypeptide?

Cell Wall in plant and bacterial cells Rigid, protective barrier Located outside of the cell membrane Made of cellulose (fiber)

Vacuoles Large central vacuole usually in plant cells Many smaller vacuoles in animal cells

Vacuoles Large central vacuole usually in plant cells Many smaller vacuoles in animal cells Storage container for water, food, enzymes, wastes, etc.

Centriole Aids in cell division (mitosis) Usually found only in animal cells Made of

Centriole Aids in cell division (mitosis) Usually found only in animal cells Made of microtubules Where else have we talked about microtubules?

Flagella and Cilia Flagella=whiplike tail for swimming Cilia= hairlike structures for movement

Quick Review Which organelle is the control center of the cell? Nucleus Which organelle

Quick Review Which organelle is the control center of the cell? Nucleus Which organelle holds the cell together? Cell membrane Which organelles are not found in animal cells? Cell wall, central vacuole, chloroplasts Which organelle helps plant cells make food? Chloroplasts What does E. R. stand for? Endoplasmic reticulum
