Make predictions comparing kale spinach and collard greens M

Make predictions comparing: kale, spinach, and collard greens

Make predictions with the following:

1. Chlorophyll determination (which one will have more kale, spinach or collard greens)

2.Total Protein:((which one will have more kale, spinach or collard greens)

3. TLC – Plant pigments (which one will have more kale, spinach or collard greens)

4. SDS-PAGE – separation of rubisco subunits and light harvesting complex

(which one will have more kale, spinach or collard greens)

hypothesis must be stated in a if, then, because format.

Solution

1)

Usually darker green vegetables are known to have more chlorophyll content. In this context, all the three kale, collard greens and spinach must have higher chlorophyll content as they all are equally greenish. But, technically it has been studied that spinach tops the list of most of the green vegetables in having higher amount of chlorophyll per cup (24gms).

2)

The protein content found to be present in 100gms of Kale is 4.3g, in that of collard green is 3g and that of spinach is 2.9g. So, Kale has higher protein content. Kale is a healthy nutrient with 36 calories of energy per cup and it has 0 fats and 5g of fiber.

3)

Kale has plant pigments like lutein, beta-carotene and chlorophylls. Collard greens have pigments like beta-carotene and lutein zea-xanthin. Spinach has pigments like chlorophylls, lutein, beta-carotene, zea-xanthin or any xanthophyll.

4)

Based on the habitat in which these plants are growing, spinach will have more Rubisco subunits and light harvesting complex as it grows in tropical areas. Tropical regions will have sun exposed very much and the tendency for the plant to carryout photosynthesis will be very high. In that context, spinach will be followed by collard greens as they are seen equally well in tropical and temperate countries. Then both are followed by Kale. Kale is a winter crop.
