Bell Ringer questionWrite down things inside a cell you al-
ready know.

Organelles of a cell 1. Plasma membrane: the outer membrane of the cell2. Cytoplasm
Things inside the cytoplasm: a. Centrioleb. Ribosomec. Mitochondriond. Vacuole
e. Endoplasmic reticulum f. Golgi complex g Lysosome h. Chloroplast (only for plants)3. Nucleus Things inside the nucleus: DNA

Activity Label each organelle and write its
function on the cell diagram booklet.

Special organelles• Mitochondria: found in all eukaryotic cells
(both in plant cells and animal cells)Function: extraction of energy from nutrients
through cellular respiration (chemical res-piration). Power house of a cell.

Special organelles• Chloroplast: found only in plant and
algae cells Function: photosynthesis/ contains
chlorophylls

Cell wall: found primarily in plants.Function: provides support and protec-
tion.

Cellular communication• How do cells communicate with each
other? Receptor molecules (proteins embed-
ded in the plasma membrane) play an important role in the interactions. between cells.

Cellular communication con’t
Receptor molecules recognize specific hormones or neurotransmitters and deliver the information to the interior of the cell.
Two types of agents of cellular com-munication:
1) Hormones i.e.) growth hormone2) Neurotransmitters i.e.) acetylcholine

Cellular communication con’t1) Hormones
i.e.) growth hormoneChemicals that are secreted by en-
docrine glands and delivered through the blood to affect target cells.
2) Neurotransmitters i.e.) acetylcholine Chemicals that are secreted from one
neuron cell and carry the impulse to the next neuron.
