Learning Objectives:

Identify a prokaryotic cell and a eukaryotic cell

differentiate between a prokaryotic cell and a eukaryotic cell

explain the functions of various organelles present in a cell

differentiate between plant cell and animal cell

TASK 1 : PREPARING AND GUESSING RIDDLES

For Learning outcome/outcomes: explain the functions of various organelles present in a cell

Task 1: Step one: The student shall prepare riddles about the functions of various cell organelles and parts of cell.(The teacher shall allocate cell organelles to various groups/individual students) For example:

To manufacture food in plants is my job, I make it myself and do not rob,

I am a member of the plastids group, and contain stroma and grana

and I don’t care for produce per annum

I am the barrier between inside and outside of the cell, I am flexible like gel

I allow useful substances to move in and out It there is a harmful one,

I order it to get out.

I am composed of cisternae and vesicles Which are membrane- bound stacks

Lipids and proteins I am used to pack

I am the control centre in cells

Which are eukaryotic I contain the material

Which has info that is genetic

Remedial Measures:

For preparing riddles, if the student is unable to prepare riddles of good quality, the teacher shall assign a group mentor who shall help these students.

If the students are not able to guess the correct answers, the concepts shall be explained again.

Task 2 : MODEL MAKING

For Learning outcome/outcomes:

differentiate between a prokaryotic cell and a eukaryotic cell

differentiate between plant cell and animal cell

Task : Teacher should create groups of students and allocate one of the following topics to each group:

Prokaryotic cell

Eukaryotic cell

Animal cell

Plant cell Each group would be asked to prepare an outline model of the topic allocated.

Animal Cell Plant Cell

Remedial Measures:

For model making, if the students are unable to make the appropriate model, then the teacher should provide them with diagram and guidance.

If still the students are not able to complete the task, reshuffling of groups should be done, taking care of the students’ intellect.
