process continues until the concentration of the substance is the same on both sides of the
membrane. This is considered __________________.
6. The circles in the diagram represent oxygen molecules. Based on what you know about diffusion,
which way will oxygen diffuse in this example? Into the blood from the lungs, or out of the blood to
the lungs?
7. _____________ is the diffusion of WATER molecules across a semi-permeable membrane. The
movement of water into and outs of cells depends on _____________.
8. Use the pictures of the red blood cells to answer these questions.
a. When water is at a higher concentration outside the cell than inside the cell water will move
_______ the cell and the cell will _________.
b. When water is at a higher concentration inside the cell than outside water will move ______ of
the cell and the cell will ___________.
c. When water is evenly concentrated inside and outside of the cell the cell is said to be at
________________.
9. Osmosis and diffusion are both examples of _____________ transport because they are moving
molecules from a high to low concentration which is with the concentration gradient and no energy is
required. _____________ transport moves molecules from low to high concentration or ________ the
concentration gradient and therefore requires the use of energy or _____.
10. What would happen to a salt water fish placed into a freshwater environment?
Station 3: Mitosis and Meiosis
1. Cells reproduce by a process called cell ______________. The cell ___________ is the sequence of
stages of growth and division that the cell undergoes. The three stages of the cell cycle include
______________, __________________ and cytokinesis.
2. Label the lettered cell pictures with the name of the cell cycle, then identified the numbered
structures involved in the process. Some are labeled for you. Numbers 1 and 8 are the same.
Nuclear membrane
Nucleolus
3. At the end of mitosis there are ______ daughter cells that are genetically identical.
4. During ____________ a cell divides into four _____ cells, each with half the number of chromosomes
(haploid). Sex cells of males are called _________ cells and sex cells of females are called ____ cells.
5. Looking at the picture, how many divisions does Meiosis go through?
6. At the end of Meiosis 1 the two new cells have ____________ the number of chromosomes but they
are still doubled. Meiosis 2 separates the doubled chromosomes and four sex cells are produced,
each with only ______ chromosomes from each original homologous pair.
7. Mitosis is used for asexual reproduction, whereas Meiosis is used for _________ reproduction.
8. One thing that is left out of the poster that takes place during Meiosis 1 and increases genetic
variation is pictured below. This process is known as: ___________-_______.
Station 4: Photosynthesis and Respiration
1. Photosynthesis is the process by which green plants and certain bacteria use the energy from the
______ to convert carbon dioxide and water into the simple sugar ___________ C6H12O6 and
___________.
2. What do plants and animals use glucose as a source of? _____________________
3. The process of photosynthesis takes place in the ______________ of plants where light energy is
absorbed by the green pigment _______________. Chlorophyll is found within a plant cell organelle
called the ________________.
4. Write the chemical equation for Photosynthesis.
5. What gas is released as a product of photosynthesis? _______________
6. Leaves have tiny pores called __________________ which allow water and gases to pass in and out of
the plant. The gas __________ ____________ is coming INTO the leaf and ____________ is going out
of the leaf.
7. ____________ _______________ is a process by which cells break down glucose to release stored
__________.
8. Respiration takes place in the organelle called the ____________________.
9. Write the chemical equation for respiration.
10. The form of energy created by respiration is called ________.
