chloroplast
mitochondria
nucleus
cell membrane
Apply scientific knowledge and solve: Energy is required by all the cell organelles to function properly. One of the cell organelle is called the power house of the cell. Suggest the name of this cell organelle. [strand ii; level 5-6]
chloroplasts
mitochondria
nucleus
vacuoles
Outline the function and name of the cell organelle which is found only in plant cell and not in animal cell. name of the part of the plant cell does the process of photosynthesis take place? [strand i; level 7-8]
cell membrane, which decides the entry and exit of substances in and out of the cell
mitochondria, helps in generating energy for the cell
chloroplasts, helps in making glucose by the process of photosynthesis
lysosomes, which helps in digesting the unwanted material (waste material) in the cell.
State which is the correct statement. [strand i; level 5-6]
prokaryotes are cells without distinct nucleus. Eg- plants
eukaryotes are cells with distinct nucleus. Eg- animals
Prokaryotes are cells with distinct nucleus. Eg- animals
Eukaryotes are cells without distinct nucleus. Eg-plants
Apply your understanding of the cells and answer: A guard is standing at the main door of a house. He is responsible for the entry of exit of all the people in and out of the building. The security guard ensures that the unknown person does not get the entry inside the house. Similarly, there is one cell organelle which decided the entry and exit of substances into the cell. If you were some bad guy trying to sneak into an animal cell, which cell organelle would be there to stop you? [strand iii; level 1-2]
nucleus
mitochondria
cell membrane
cell wall
Solve this: Albie, was taught the difference between autotrophs and heterotrophs by his mother. he got confused about the function of each one of them. As a science student and a friend of Albie, help him choose the correct option. [strand ii; level 7-8]
autotrophs prepare their own food and the process is called photosynthesis. Eg- plants
heterotrophs prepare their own food and the process is called photosynthesis. Eg- birds
autotrophs depend on others for their food. Eg- fishes
heterotrophs depend on other organisms for their food. Eg- plants.
Solve the mystery: cells are divided into categories as: unicellular and multicellular; eukaryotic and prokaryotic. Choose the correct explanation of the category mentioned. [strand ii; level 5-6]
unicellular organisms have only one cell. Eg- grasshopper.
prokaryotic cells do not have a distinct nucleus. Eg- bacteria
multicellular organisms are made up of many cells. Eg- bacteria
eukaryotic cells do not have a distinct nucleus. Eg- grasshopper.
Apply your understanding of animal and plant cell and make a judgement: According to the information in the given chart, what type of cell is cell X? [strand iii; level 3-4]
bacteria cell

DNA stores the genetic information, which is present inside the nucleus of the cell in every human body.
nucleus contains the genetic information which is present inside the DNA of every human body.
The genetic information for every human can be present in either of DNA, cells or nucleus.
