CONCLUSION
Concluded that plants are
made of cells.
Concluded that animals are
made of cells.
“all cells come from other
cells”
Rough E.R- Maze of passageways that carry materials from one part of the cell to
another.
Ribosome- Site where proteins are made
Smooth E.R.- Maze of passageways that carry materials from one part of the cell to
another
Mitochondria- powerhouse of the cell because they convert the energy found in the food
to molecules into energy that cell can use to carry out its functions.
Vacuole- Stores food, water, waste, and other materials
Cell Membrane- Protects the cells and controls what substances come into and go out of
the cell.
Cytoplasm-A clear, thick, gel-like fluid in between the cell membrane and the nucleus.
Lysosome- Small and round, they contain chemicals that break down large food
molecules into smaller ones, and old cell parts so they can be used again. They are called
the “clean-up crew”.
Golgi Body- Looks like flattened sacs and tubes. They receive proteins and other newly
formed materials from the E.R., package them, and distribute them to other parts of the
cell or outside. Called the “mail room” of the cell. Located towards the outside of the
cell.
Cell Wall- Gives the plant support, structure, and protection so they can stand up straight
and reach for the sun.
Chloroplasts- Contain the pigment, which captures sunlight and converts it to chemical
energy. This happens during photosynthesis.
Nucleus- The “control center” of the cell, directing all of its activities.
Nucleolus- Ribosomes are made here. Located in the middle of the nucleus.
Nuclear Envelope- Membrane that protects the nucleus.
Pores- Area where materials pass in and out of the nucleus.
Chromatin- The genetic material that holds the instructions for directing the cell’s
functions.
