which multiple biochemical processes can proceed simultaneously and independently. The cell membrane of the plant cell has a phospholipid bilayer. Plant cells often have a central vacuole‚ which is a large membrane-bounded sac that stores proteins‚ pigments‚ and waste materials. The central vacuole‚ in most mature plants‚ occupies a major portion of the internal volume of the cell and has a phospholipid bilayer. Inside the nucleus‚ an organelle with a phospholipid bilayer that regulates cell activity

Background Information: Photosynthesis is the process by which sunlight is captured by chloroplasts within plant cells and turned into energy. This energy is used to help the plant grow roots‚ leaves‚ flowers and fruit. Energy is required by living things to: change shape‚ transportation‚ movement‚ growth‚ reproduction‚ etc. Red and blue light have the greatest effect on plant growth after white light The main pigment is chlorophyll which reflects green lights l Green and yellow light are the least

Lesson 4 Laboratory: Photosynthesis Introduction: Elodea is a species of aquatic plant often called waterweed. Like other plants‚ Elodea absorbs carbon dioxide and releases oxygen during photosynthesis. In this lab‚ an Elodea specimen is submerged in water under a lamp with a filter that can change the color of the light. We will measure Elodea’s rate of photosynthesis by measuring the amount of oxygen it produces. We will investigate the effects of light color and light intensity on Elodea’s rate

obstructed by black paper‚ and red‚ blue‚ and green translucent filters. I. Abstract Photosynthesis is a process in which plants use light‚ water‚ and carbon dioxide to produce sugars‚ water and oxygen. Chlorophyll a and chlorophyll b‚ in the chloroplasts of a leaf‚ are responsible for absorbing wavelengths of light for use in photosynthesis with red and blue wavelengths being optimal. Testing for the most productive wavelength of light was done using four separate geranium leaves that were
