Looking Inside Cells

Instruction You will complete the pages you have been given using the information provided. You need to write a description of function You need to draw and color the picture You need to create and analogy using everyday things in your life to associate the organelle to. Example: Mitochondria is like a power plant You need to note if it is found in every cell, plant cell, animal cell

Inside A Cell Organelles- tiny cell structures that carry out specific function within the cell. Along with many other small features that are smaller than a cell.

Animals Vs Plant Cells Plant cells contain a cell wall and chloroplasts. Plant cells contain one large vacuole, it is the largest organelle in a plant cell. Animal cells contain lysosomes. Animal cells contain many small vacuoles. The largest organelle in the animal cell is the nucleus.

Cell Membrane The semi-permeable membrane that encloses the contents of a cell. Found in all cells.

Cell Wall The rigid, outermost layer of a plant cell. A plant’s cell wall helps to protect and support the cell, making is square.

Chlorophyll The green pigment in the leaves and stems of plants that is necessary for the production of plant food by photosynthesis.

Chloroplasts Only found in plants. A small oval green bit of protoplasm that contains chlorophyll and is the location of photosynthesis.

Cytoplasm Inherited genetic material in a cell, not specified by its own nucleus. The gel like material that surrounds the organelles.

Endoplasmic Reticulum Organelle in the cytoplasm that moves materials around in a cell and is made up of a complex series of folded membranes; can be rough or smooth.

Golgi Bodies Golgi body is the cell’s mail room. Organelles that package cellular material (proteins) and transport them within the cell or out of the cell.

Lysosomes The organelle that contains enzymes to break down or digest organic compounds and old organelles.

Mitochondria Any of the very tiny rod-like or string-like structures that occur in nearly all cells of plants and animals, and that process food for energy. Known as the powerhouses of the cell, mostly found in the muscle cells to give them energy.

Nucleolus A small spherical body in the nucleus of a cell, consisting of protein and RNA.

The Nucleus The part of a cell that controls growth and reproduction. The control center of the cell.

Ribosome Small structure on which cells make their own proteins.

Vacuoles A membranous enclosure within a cell that contains substances. The storage centers of the cell. Plant: Animal:

Specialized Cells In many-celled organisms, cells are often organized into tissues, organs, and organ systems. Blood cells Bone cells Nerve cells

Blood Cell Draw and label in specialized cell section

Bone Cells Draw and label in specialized cell section

Nerve Cell Draw and label this in the specialized cell section

Bacterial Cells While a bacterial cell does have a cell wall and a cell membrane, it does not contain a nucleus. The bacterial cell’s genetic material, which looks like a thick tangled string, is found in the cytosplasm.
