Ch7.3 (Ch7 Vocabulary Guide)
A minute structure within a plant or animal cell that has a particular job or function.
Transportation of cell’s products
Respiration or Photosynthesis
Organelles that surround cells for support:
Cell Membrane= Semi-permeable,
controls what enters and leaves the cell, outer containment envelope.
gives structure to a cell (#14)
This organelle controls cell activities and reproduction
Nucleus = control center for activities & reproduction, DNA & chromosomes housed here.
Nucleolus = contains and makes RNA
Control center for plant and animal cells:
Chromatin = protein composing chromosomes
Nuclear membrane = protects and controls what goes in and out of the nucleus
(notice the nuclear pores in this picture of a nucleus)
Cytoplasm:or cytosol, = gel surrounds the organelles, contains enzymes
specializes in the production & transport of lipids and membrane proteins
Rough ER has ribosomes Smooth ER lacks ribosomes
Ribosomes: Whereproteins are manufactured.
“Rough” with Ribosomes
for protein synthesis
For transport of materials
where cell products are modified and packaged in vesicles for export from the cell.
“Sacks” for making
& storing Secretions
Do you see 2 Contractile vacuoles
in this Paramecium?
Contains digestive enzymes
Breaks down large molecules
Mitochondria = site where energy is released from glucose in the form of:
