All plants…
• Eukaryotic & multicellular• Are producers – an organism that makes its
own food by using an outside energy source (the sun)
• Have cell walls (organelle only in plants)
• Have chloroplasts (organelle only in plants)
![Page 19: Plants. Video – “Life” by BBC Answer the questions in your ISN.](https://reader036.fdocuments.us/reader036/viewer/2022062407/56649dab5503460f94a9a0a8/html5/thumbnails/19.jpg)

Organelle that converts light energy to chemical energy through a process called photosynthesis
(we’ll talk about that later)
What is a chloroplast?

Photosynthesis• A series of chemical reactions that convert
light energy, water and carbon dioxide into the food-energy molecule glucose and give off oxygen.
• Occurs in the chloroplasts• Chloroplasts contain the pigment chlorophyll,
a chemical that absorbs and reflects light.• Leaves appear green because the chlorophyll
reflects green light and absorbs all the other colors of light.
![Page 50: Plants. Video – “Life” by BBC Answer the questions in your ISN.](https://reader036.fdocuments.us/reader036/viewer/2022062407/56649dab5503460f94a9a0a8/html5/thumbnails/50.jpg)
Photosynthesis
• C=Carbon• O=oxygen• H=hydrogen• CO₂ = carbon dioxide• H₂O = water• C₆H₁₂O₆ = sugar/glucose
6CO₂ + 6H₂O
C₆H₁₂O₆ + 6O₂Light energy
Chlorophyll

Cellular Respiration• All organisms require energy (usable power)
to survive.• Energy is in the chemical bonds in food
molecules.• Cellular respiration is a series of chemical
reactions that convert the energy in food molecules into a useable form of energy called ATP.
![Page 52: Plants. Video – “Life” by BBC Answer the questions in your ISN.](https://reader036.fdocuments.us/reader036/viewer/2022062407/56649dab5503460f94a9a0a8/html5/thumbnails/52.jpg)
• ATP= (adenosine triphosphate) • ATP is the energy used for all cellular
processes (everything the every cell does) • Example: muscle contraction uses 2 million
ATP molecules per second. Without ATP we would die.

What are mangroves?
Mangroves are various kinds of trees and shrubs that grow in saltwater habitats in the tropics
and subtropics.
