the factories of photosynthesis.

Variables: The variables that might affect the rate of photosynthesis in this experiment are: Temperature: When the temperature rises so does the rate of photosynthesis; this is because as the temperature around the plant rises the enzymes controlling photosynthesis inside the chloroplasts heat up and start moving around faster, the fast moving molecules collide with other fast moving enzymes causing them to react....

In this experiment we were told that we would be measuring the rate of photosynthesis.

Prediction: I predict that as the light source (desk lamp) is moved closer to the pondweed (Elodea), the rate of photosynthesis will increase therefore more oxygen will be produced creating more bubbles.


Where does photosynthesis take place in a plant cell?

The internal structure of the leaf is also adapted to promote efficient photosynthesis:

Next, a leaf was retrieved from the top of a bean plant and sealed from the air in the laboratory via thumbscrews inside the leaf chamber of the apparatus....


of the leaf, and the products of photosynthesis, ..

Cells of the mesophyll make up the bulk of internal leaf tissue and are the major site of photosynthesis in a plant by virtue of containing large populations of chloroplast organelles. The differentiation of the mesophyll and its coordinated expansion is important to leaf function because light interception by chloroplasts and gas exchange in the internal airspaces of the leaf are crucial to optimise rates of photosynthesis. In dicotyledonous leaves there are two types of mesophyll cell; palisade mesophyll and spongy mesophyll. Palisade mesophyll cells are elongate and form a layer beneath the upper epidermis, whereas spongy mesophyll cells are internal to the lower epidermis. Mesophyll cells in monocotyledonous leaves are often highly lobed. All mesophyll cells contain large populations of chloroplasts, which enable the leaf to carry out photosynthetic carbon assimilation.

Nucleus: this contains genetic make (the DNA), which controls the activities of the cell.

Chlorophyll absorbs the light energy needed to make photosynthesis happen. It is important to note that not all the color wavelengths of light are absorbed. Plants mostly absorb red and blue wavelengths — they do not absorb light from the green range.

6 Answers - In what part of a plant does photosynthesis occur?

The function of a leaf is photosynthesis – to absorb light and carbon dioxide to produce carbohydrates. The equation for photosynthesis is:

Palisade cell layer at top of leaf:

A major role of leaf mesophyll cells is to contain large populations of chloroplasts, which carry out photosynthetic carbon assimilation facilitating plant growth.
