Do Now: Draw a picture of a cell and label as many parts as you can.

The Cell The parts of a cell are called? Organelles. Organelles means “little organs”

Types of Cells Plant cell Animal cell

The Cell Membrane Surrounds the cell Allows materials to move in and out The Cell Membrane (1min 1sec).asf

Chromosomes Made of DNA Instructions for building the body

Nucleus Contains the Chromosomes Found in the center of the cell Organelles - The Nucleus (1min 6sec).asf

Nuclear Membrane Separates Chromosomes from the rest of the cell.

Cytoplasm Supports the Organelles. Many chemical reactions happen here. The Cytoplasm (21sec).asf

Just like complex organisms, cells are able to survive by coordinating various activities. Complex organisms have a variety of systems, and cells have a variety of organelles that work to help the cell survive. Describe the role of two organelles. In your answer be sure to include: The names of two organelles and the function of each. An explanation of how the organelle does it’s job. The name of the organelle and the name of a part of the human body that has a similar function.

Mitochondria Site of cellular respiration (production of ATP) Powerhouse of the cell Organelles - Mitochondria.asf

Ribosomes Site of protein synthesis (use information from DNA to make proteins) Very tiny

Endoplasmic Reticulum Transports materials around the cell Network of passageways Organelles - The Endoplasmic Reticulum (33sec).asf

Golgi Body Packages materials for export out of the cell

Lysosomes Contains enzymes that digest foreign particles and old cell parts

Storage space for food, water or waste products. Vacuole Storage space for food, water or waste products. Vacuole

Write down a part of the cell we learned today that you think is most important and describe why you think it is most important. Ask a neighbor what they thought was most important and why. Pick ONE. Why did you decide to pick that one?

Cell Parts (organelles) There are two types of cells that we are going to be talking about. Animals are made up of what type of cell? Answer: Animal cells! (includes humans). Plants are made up of what type of cell? Answer: Plant cells!

Animal Cell

Centrioles Cylindrical structures only found in animal cells that aid in replication (cell division).

Centrioles and Spindle Fibers Centrioles are anchor point for spindle fibers Spindle fibers appear during cell division

Parts of the Plant Cell Plants have organelles in them that Animal cells don’t have.

Cell Wall Rigid structure that encloses, supports and protects the cells of plants, algae, fungi and most bacteria. Cell walls in plants are made of cellulose.

Cell Wall Protective outer layer on plant cells Adds support

Chloroplasts Structures found only in the plant cell. Site of photosynthesis. Photo = Light, Synthesis = To make. So Photosynthesis means to make something (glucose) using Light!

Chloroplast Contain Chlorophyll Site of Photosynthesis Chloroplasts and Photosynthesis (50sec).asf
