Levels of Organization Elements The colored spheres represent atoms. Which examples represent the same element?

Levels of Organization Molecules and Compounds Carbon dioxide is a compound. So is water.

Levels of Organization The graph compares the percentages of some molecules found in a bacterial cell and in an animal cell. What would be a title for the graph?

Levels of Organization Living things are organized in levels of increasing complexity. Complete the missing terms to show the patterns of organization of organisms from simple to complex.

Discovering Cells Needs of Cells A single cell has the same needs as an entire organism. What material moves in the direction shown by each blank arrow?

Discovering Cells Eyepiece lens A Compound Microscope This microscope has a 10 x lens in the eyepiece. The revolving nosepiece holds three different lenses: 4 x, 10 x, and 40 x. Revolving nosepiece Lenses Stage Light rays Light source Slide Lens

Discovering Cells Resolution The images in colorful photographs actually consist of only a few ink colors in the form of dots. This circle has been enlarged to show a tiny section of a picture of a bird's wing.

Cells and Homeostasis Energy From Food Florida’s orange crop comes from the energy captured in photosynthesis. The 2008– 2009 crop totaled 162 million boxes. Which process applies to each organism?

Cells and Homeostasis Diffusion Some materials move across the cell membrane by way of diffusion. Show the overall direction that molecules will travel as a result of diffusion.

Looking Inside Cells A Typical Animal Cell Each kind of cell structure has a different function within a cell. Where is the cell membrane?

Looking Inside Cells Chromatin Ribosomes Nucleolus Nuclear envelope Pores What does the nuclear envelope do? In what types of cells would What do ribosomes do? you expect to find a lot of mitochondria? Organelles of a Cell The structures of a cell look as different as their functions. Where do you find these structures in the cell diagram?

Looking Inside Cells Plant Cell These illustrations show typical structures found in plant cells. What is the function of each structure?

Looking Inside Cells Animal Cell These illustrations show typical structures found in animal cells. What is the function of each structure?

Looking Inside Cells Compare and contrast the structures present in plant cells and animal cells.

Looking Inside Cells Golgi Apparatus How can this sentence be completed? The Golgi Apparatus is an organelle that ______ and ______ materials made in the _____.

Looking Inside Cells Model for a Cell Function How do the parts of a cell function in ways that are similar to the parts of a building?

Looking Inside Cells Chloroplast A chloroplast captures energy from sunlight and changes it to a form of energy cells can use in making food. Chloroplasts make leaves green because leaf cells contain many chloroplasts.

Cell Division Comparing Cell Cycles The table below compares the length of different cell cycles.

Cell Division Interphase: Preparing to Divide The changes in a cell during interphase prepare the cell for mitosis.

Cell Division When one cell splits in half during cell division, the result is two new cells. Each of those two cells can divide into two more, and so on.

Cell Division Mitosis: Prophase Mitosis begins with prophase, which involves further changes to the cell.

Cell Division Centriole pairs Spindle fiber Centromere Chromatids The Cell Cycle Cells undergo an orderly sequence of events as they grow and divide. What are the missing parts of the stages?

Cell Division Firmicutes Certain bacteria divide only once every 100 years! Bacteria known as Firmicutes live in certain rocks that are found 3 kilometers below Earth’s surface. The life functions of Firmicutes occur so slowly that it takes 100 years or more for them to store enough energy to split in two.

Cell Division Length of a Liver Cell Cycle Human liver cells generally reproduce less than once per year. At other times, they can complete one cell cycle in about 22 hours.
