DATE: 22/4/2021 GRADE: 7 C CHAPTER: NUTRITION IN PLANTS Modes of Nutrition On the basis of a different mode of nutrition, organisms are categorised into two major types, i.e. (i) Autotrophs (auto-self, trobpos-nourishment) Autotrophic nutrition is the mode of nutrition in which organisms make their own food from the simple substance (e.g. CO2 and H2O) by the process of photosynthesis. Therefore, plants are called autotrophs. (ii) Heterotrophs (heteros-other) Humans and animals do not contain chlorophyll and are dependent on plants for their food in readymade form. Those organisms which cannot prepare their own food and take food from green plants or animals are called heterotrophs and the mode of nutrition isOther Modes of Nutrition in Plants There are some plants which do not contain chlorophyll in them and thus, cannot prepare their own food. These plants obtain their food from other plants or animal, i.e. they are heterotrophic in nature Parasitic Plant A parasitic plant is one that...

Integration with Art: Chlorophyll painting Chlorophyll, the green pigment found in a plant’s leaves, is a key ingredient in  the process of photosynthesis. It also makes great paint! Material required (to be sourced by the students): 8-10 leaves , a white sheet  of paper, a metal spoon. Draw the outline of the bark of a tree as shown in the image below.  Press firmly on the leaves with a metal spoon to extract the pigment and use it to colour the leaves of the tree. Avoid plastic spoons as they break when pressed as firmly as necessary.  The student can also ball up few leaves and use them as paintbrush to colour the leaves of the tree.  Upload the photograph/scanned copy of the work if the activity is done  Video 4 (Chlorophyll is necessary for photosynthesis)  Classwork  Which parts of the leaf did not turn blue black after the starch test?  List down the steps of conducting a starch test. Notebook work Draw and label the structure of a chloroplast. Homewo...
