Slide 3
Slide 4
Cytoplasm Jelly Like mixture Contains molecules and small cell
parts(organelles) Contains enzymes to drive chemical reactions
Slide 5
Slide 6
DNA Long molecule containing information Controls cells
activities Mutations can cause irregular cell division Complex
instructions
Slide 7
Slide 8
Nucleus Controls cells activities Stores DNA Large, Round/Oval
Shape Is made up of the following parts: Nuclear Membrane DNA
Nucleolus In both Plant and Animal Cells
Slide 9
Nuclear Membrane Surrounds Nucleus Selectively Permeable
Controls what moves into and out of the nucleus Both Plant and
Animal Cells
Slide 10
Nucleolus Found inside the nucleus Creates Ribosomes Both Plant
and Animal Cells
Slide 11
Slide 12
Mitochondrion (Mitochondria) Bean shaped with inner membranes
Breaks down sugar molecules into energy Both Plant and Animal
Cells
Slide 13
Slide 14
Ribosome Small bodies that are free within the cell or attached
to E.R. Produce Proteins Created by the Nucleolus Both Plant and
Animal Cells
Slide 15
Slide 16
Endoplasmic Reticulum (ER) Network of tubes or membranes
Carries materials through the cell Smooth and Rough ER Rough ER
have Ribosome attached Both plant and animal cells
Slide 17
Slide 18
Vacuole Fluid-filled sacs Store food, water, waste Plants store
large amounts of food, have large vcacuoles Both Plant and Animal
Cells
Slide 19
Slide 20
Golgi Bodies Packages proteins for transport Tubes and
membranes Thought of as UPS or Post Office of the cell
Slide 21
Slide 22
Lysosome Small, round with a membrane Breaks down larger food
molecules into smaller pieces Digests old cell parts Uncommon in
Plants, common in Animal Cells
Slide 23
Slide 24
Plant Cell Parts Parts that are common only in Plant cells
include: Cell Wall Chloroplast Chlorophyll
Slide 25
Cell Wall Outer Layer of Plant Cell Rigid, strong Made of
cellulose Provides Support, Protection Allows H2O, O2, CO2 to pass
into and out of cell
Slide 26
Slide 27
Chloroplast Green, oval Uses energy from sun to make food for
the plant Contain Chlorophyll
Slide 28
Slide 29
Chlorophyll Very small, round, green Provide pigment to the
plant Used during photosynthesis
