Photosynthesis

What is Photosynthesis?

Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Why do we need Photosynthesis?

We need photosynthesis to stay alive. Photosynthesis provides us with most of the oxygen we need in order to breathe. In return we exhale carbon dioxide which is needed by plants.

Light Dependent & Independent cycles

The Light Dependent Cycle converts (what goes in) light energy to (what comes out) chemical energy.

The Light Independent Cycle (aka Calvin Cycle) converts (what goes in) carbon dioxide and other compounds into (what comes out) glucose.

Why is Photosynthesis required for life?

Photosynthesis is important because it creates carbon for plants and oxygen for animals. It creates a source of life for almost all plants and animals by providing the source of energy.

Chloroplast Structure

Chloroplasts are large complex double membrane bound organelles crucial in photosynthesis.

What takes place?

The chloroplast helps in the transfer of carbohydrate to all parts of the plant, helping in a plants survival. It also captures light energy which is stored in the energy storage molecules ATP for the use in the process of photosynthesis.

What does each part do?

Chloroplast

~An organelle found in plant and algae cells where photosynthesis occurs.

Inner Membrane

~Located under the smooth outer membrane.

Outer Membrane

~The smooth outer covering of the chloroplast.

Thylakoid

~A flattened membrane sac inside the chloroplast, used to convert light energy into chemical energy.

Granum

~A stack of thylakoids in a chloroplast.

Stroma

~The fluid of the chloroplast surrounding the thylakoid membrane.

Lamellae

~The tissue that connects the grana to each other.

chlorophyll

~Green pigment in plants that absorbs light energy used to carry out photosynthesis

Why Chloroplast should get raise and better benefits

Chloroplast conducts Photosynthesis which is what keeps both plants and animals alive. It creates carbon for plants. Then the plants absorb sunlight to create oxygen for animals. The Chloroplast keeps everything alive and has a very important job. Without Chloroplast plants and animals wouldn't stay alive, so of course it deserves a raise!
