For example, when teaching a unit on plants, use statements such as: “Plants use light from the sun in the process of photosynthesis” (true), and “Plants must depend on animals for food” (false).
– Very informative computer animated videos showing the process of photosynthesis. There are two, one for land based plants and one for marine life.
In what part of the plant does photosynthesis take place
All plants, algae, and cyanobacteria which photosynthesize contain the pigment chlorophyll "a." A second kind of chlorophyll is chlorophyll "b", which occurs only in green algae" and in the plants.

Photosynthesis is defined as the formation of carbohydrates inliving plants from water and carbon dioxide (CO2). It is the mostimportant chemical pathway (series of chemical reactions) on ourplanet. Almost all of the biomass on Earth was initially createdby photosynthesis.

It should be emphasized that plants respire just like any other higher organism, and that during the day this respiration is masked by a higher rate of photosynthesis.

Algae are a very diverse group of predominantly aquatic photosynthetic organisms that account for almost 50% of the photosynthesis that takes place on Earth. Algae have a wide range of antenna pigments to harvest light energy for photosynthesis giving different types of algae their characteristic colour. Early work done with algae contributed much to what is presently known about the carbon dioxide fixation pathway and the light harvesting reactions. The processes of photosynthesis in algae and higher plants are very similar. From among the three types of carbon dioxide‐concentrating mechanisms known in photosynthetic organisms, two types are found in different types of algae. Algae are proposed to play a role in the global carbon cycle by helping remove excess carbon dioxide from the environment. Recently, algae are recognized as a promising biodiesel source due to its efficient absorption and conversion of solar energy into chemical energy.

In leafy plants, the process of photosynthesis occurs largely in the leaves. Because of this, all the necessary ingredients need to be present in the leaves for the reaction to take place. Carbon dioxide is absorbed into the leaves from the air, water is routed from the roots to the leaves, and sunlight is absorbed into the leaves through chlorophyll. Chlorophyll is a green pigment inside plant cells called chloroplasts - which also have several other structures within them. Chloroplasts are important because they are where photosynthesis takes place.
Do both plants and animals carry out photosynthesis …
Wecan only do the second thing.
The first law ofthermodynamics tells us that matter cannot becreated or destroyed. It cannot come from nothingand it cannot disappear. So the same number ofatoms (C, H, O) have to enter and leave. Let uswrite photosynthesis as a balanced equation.
