Chloroplasts in plant cells convert sunlight into chemical energy that will be used to make ATP ATP is manufactured through cellular respiration that takes place in the mitochondria Peroxisomes

The cytoskeleton Microfilaments Actin Two intertwined str in addition to s maintain cell shape by resisting tension Actin subunit Protein subunits Structure Functions motility via pseudopodia muscle contraction cell division in animals 7 nm Intermediate filaments Keratin, others Fibers wound into thick cables anchor nucleus in addition to some other organelles Microtubules a-tubulin in addition to b-tubulin dimers Hollow tube Keratin subunits Tubulin dimer maintain cell shape by resisting compression motility via flagella/cilia move chromosomes during cell division move organelles 10 nm 25 nm 3 types of cytoskeletal structures Structure of kinesin Tail Stalk Head Motor molecules like kinesin, myosin, in addition to dynein work with the cytoskeleton to produce movement

Transport vesicle Kinesin Microtubule ATP ADP+Pi Kinesin “walks” along a microtubule track Microfilaments in addition to Intermediate Filaments Networks of filaments near the plasma membrane help to maintain a cell’s shape Microfilaments aid in motility

Centrosome containing a pair of centrioles Microtubules often grow out from the region called the centrosome Cilia Flagella Cilia in addition to Flagella move the entire cell TEM of flagella Microtubule doublet Cell membrane Central pair Outer doublet Dynein Spoke Cilia in addition to Flagella have a “9 +2” arrangement of microtubule doublets

Bend The motor protein Dynein “walks” along the microtubules within the flagella on one side, causing bending Figure 7.23 A comparison of the beating of flagella in addition to cilia Plant cells are surrounded by cell walls made of cellulose Plasmodesmata connect adjacent plant cells
