Cell stwucturs :>

Chromatin

• forms the boundary of the cell, acts as a selective barrier allowing certain materials to pass but not others

• • Consists of DNA and protein, condenses to form chromosomes

• site of photosynthesis; produce food using light energy, CO2 and H2O

• Site of cellular respiration, produces ATP from sugar

Cell Membrane

• Supports the shape of the cell, anchors organelles and serves as a "track" for organelles to move on.

• site of photosynthesis; produce food using light energy, CO2 and H2O

• Forms the boundary of the cell, acts as a selective barrier allowing certain materials to pass but not others.

• Consists of DNA and protein, condenses to form chromosomes

Cytoskeleton

• Proteins found outside an animal cell that function in support, adhesion and movement

• Consists of DNA and protein, condenses to form chromosomes

• Supports the shape of the cell, anchors organelles and serves as a "track" for organelles to move on.

• -may be smooth:

  builds lipids and

  carbohydrates

  -may be rough:

  stores proteins

  made by attached

  ribosomes

Chloroplast

• Site of photosynthesis; produce food using light energy, CO2 and H2O

• Protective external to the cell membrane, consists of chitin

• Where the components of the ribsomes are synthesized and assembled; found in the nucleus

• Contains most of the genes that control the eukaryoitic cell, contains the nucleolus and chromatin

Extra Cellular Matrix

• Part of the endomembrane system, sacs of enzymes used to digest food and old, worn out cell parts

• Proteins found outside an animal cell that function in support, adhesion and movement

• Consists of flattened membranous sacs; receives transport vesicles from the ER. modifies ER produces, produces secretory vesicles.

• Protective layer external to the cell membrane, consist of chitin

Fungus Cell Wall

• Protective layer external to the cell membrane, consists of cellulose

• Consists of flattened membranes sacs; recieves transport vesicles from the ER, modifies ER produces, produces secretory vesicles

• Protective layer external to the cell membrane, consists of chitin

• Where the components of the ribsome, are synthesized and assembled; found in the nucleus

Golgi Apparatus

• Site of cellular respiration, produces ATP from sugar

• Consists of flattened membranes sacs; recieves transport vesicles from the ER, modifies ER produces, produces secretory vesicles

• Part of the endomembrane system, sacs of enzymes used to digest food and old, worn out cell parts

• Where the components of the ribosome are synthesized and assembled; found in the nucleus

Lysosome

• Part of the endomembrane system, sacs of enzymes used to digest food and old, worn out cell parts

• Proteins found outside an animal cell that function in support, adhesion and movement

• Double membrane that forms the boundary between the nuclear contents and te cytoplasm; perforated with pores

• Where the components of the ribsome are synthesized and assembled; found in the nucleus

Mitochondria

• Protective layer external to the cell membrane, consists of chitin

• Double membrane that forms the boundary between the nuclear contents and the cytoplasm; perforated with pores

• Part of the endomembrane system, sacs of enzymes used to digest food and old, worn out cell parts

• Site of cellular respiration, produces ATP form sugar

Nuclear Membrane

• Site of cellular respiration produces ATP from sugar

• Where the components of the ribosome are synthesized and assembled; found in the nucleus

• Double membrane that forms the boundary between the nuclear contents and the cytoplasm; perforated with pores

• Proteins found outside an animal cell that function in support, adhesion and movement
