What is chlorophyll ck12?

What is chlorophyll ck12?

The most common photosynthetic pigment is chlorophyll, which absorbs blue-violet and red wavelengths of light, and reflects green. Various types of chlorophyll exist, including chlorophyll a and chlorophyll b. Accessory pigments absorb other colors of light and then transfer the energy to chlorophyll.

What is waterweed used for?

Provides excellent cover for aquatic insects and fish and serves as a source of food for various pond wildlife. One of the few aquatic plants that provides underwater habitat during the winter months. Modest amounts of elodea are generally considered beneficial for the pond ecosystem.

Why is Elodea used in photosynthesis?

This North American pondweed is widely recommended for demonstrating oxygen formation during photosynthesis. Elodea is cheap and easy to grow, but other pondweeds can also be used.

What is the pigment that allows photosynthesis to occur?

Green plants have the ability to make their own food. They do this through a process called photosynthesis, which uses a green pigment called chlorophyll. A pigment is a molecule that has a particular color and can absorb light at different wavelengths, depending on the color.

Does waterweed use energy?

Sun. Like other plants, elodea gets its energy from photosynthesis. Photosynthesis uses sunlight and other elements to manufacture food for the plant. The food is essential in keeping the elodea plant alive and healthy.

Does waterweed reproduce?

Reproduction – Common waterweed reproduces sexually and asexu- ally. Common waterweed is dioecious and, with the female form being more abundant than the male, sexual reproduction is rare. Sexual reproduction produces cylindrical fruit capsules. Asexual reproduction is common and occurs by stem branching, growth buds.

Why do Elodea cells have chloroplasts?

This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).

Why does chloroplast move in Elodea?

It appears to be a response to light intensity. In extreme light exposure, the chloroplasts line up like the blades of a Venetian blind to let the light pass through. On dim, dark days, they flip their alignment, like the Venetian blind closing, to catch what light is present.

What is the role of ADP and NADP+ in photosynthesis?

Photosynthesis converts these energy- depleted compounds (ADP and NADP+) back to the high energy forms (ATP and NADPH) and the energy thus produced in this chemical form is utilized to drive the chemical reactions necessary for synthesis of sugars and other carbon containing compounds (e.g., proteins, fats).

What is the role of NADP in photosynthesis?

NADP+ functions as a carrier to transfer high energy electrons from chlorophyll to other molecules.
