Life Science Photosynthesis Guided Notes

Photosynthesis & Respiration

Photosynthesis

• The process by which a cell captures the energy in sunlight and uses it to make food is ______________________________

• During photosynthesis, plants use energy from the sun to convert carbon dioxide and ____________________ into oxygen and ____________________.

• Label the diagram below:

• The word equation for photosynthesis is ________________________________________________________.

• The chemical formula for carbon dioxide is _______________________.

• H₂O is the chemical formula for ________________________.

• The chemical formula for glucose is ___________________.

• 0₂ is the chemical formula for _______________________.

• Raw materials (carbon dioxide and water) are on the ___________________ side of the equation.

• ______________________ (glucose and oxygen) are on the right side of the equation.

• What happens to the products of photosynthesis?

______________________________________________________________

• What does your body do with the food that you eat?

______________________________________________________________

Respiration

• The process by which cells “withdraw” energy from glucose is called ______________________________. 

• During respiration, cells break down simple _______________________ molecules such as glucose to release the energy they contain.

• The word equation for respiration is __________________________________________________________.

• _______________________ for respiration are glucose and oxygen.

• Products for respiration are ________________________ and ______________________________.

Types of Respiration:

• _______________________________ refers to respiration that requires oxygen.

• How is aerobic respiration related to respiration?

      _____________________________________________________________

• Photosynthesis and respiration can be thought of as ______________________ processes.

• These 2 processes form a cycle that keeps the levels of ____________________ and _________________________ fairly constant in the atmosphere.

• Some cells are able to obtain energy from food without using ___________________________.

• Fermentation is an energy releasing process that does NOT require ______________________.

• Some _________________________ organisms live where there is no oxygen, such as deep oceans or in the mud of lakes and swamps.

Cell Project Overview

The Incredible Edible Cell

You will be required to construct a model of a plant OR animal cell (I will pick for you).  All models must be made out of edible materials that will remain fresh at least 3 days

without refrigeration. Avoid using materials that have an unpleasant odor or that

may be considered offensive!

REMINDER : FOR PLANT CELLS COLOR IS IMPORTANT.

Each model must include all of the following organelles:

• Cell wall (if plant cell) • Ribosomes

• Cell membrane • Mitochondria

• Nucleus • Vacuoles

• Cytoplasm • Lysosomes (if animal cell)

• Endoplasmic Reticulum (smooth and rough) • Chloroplasts (if plant cell)

• Golgi Bodies

Grading:

Grades will be based on the following questions:

Ö Is your name on the project?

Ö Is the cell type identified? Tell if it is a plant or animal cell.

Ö Is the model a 3-D representation of a plant or animal cell?

Ö Are all the organelles included? (11 for plant and 10 for animal cells)

Ö Are the organelles correctly labeled?

Ö Is the chart filled out/ are all functions explains and a rationale given for the representation

Ö Are the relationships between the parts (if any) shown correctly? Are the

ribosomes on the endoplasmic reticulum? Is the endoplasmic reticulum

near the nucleus? If a plant cell, are the chloroplasts around the vacuole?

Ö Are the materials acceptable?

You may use the following materials, but they cannot count as part of the cell:

container, plastic wrap, paper, or toothpicks.

Non-Edible Cells

You can also choose to do a non-edible cell.  The same organelles must be identified and the function must be explained.  If you choose to do a non-edible cell it must be three-dimensional.  If you choose a non-edible option no portion of the cell can be anything that might spoil.  

·         You may use Styrofoam to represent the cell and other materials to represent organelles (play-doh, pipe cleaners, etc.).

·         You may also create a poster as long as the organelles are not just drawn on the poster, they need to stick out (3-d)

·         You will be graded using a similar rubric as the edible cell.

Photos of examples of each type of model are available at slavichscience.blogspot.com.
