1) Indicate whether the following statements are True (T) or False (F).

(a) Unicellular organisms have one-celled body. (T/F)

Ans: – True.

Explanation – (Single cell organelles are called unicellular)

(b) Muscle cells are branched. (T/F)

Ans: – True.

Explanation – (Multiple cells are present in muscle)

(c) The basic living unit of an organism is an organ. (T/F)

Ans: –   False

Explanation – (it will be cell).

(d) Amoeba has irregular shape. (T/F)

Ans: – True.

Explanation – (Amoeba doesn’t have a specific shape)

2) Make a sketch of the human nerve cell. What function do nerve cells perform?

Ans: –

Different activity of our body is controlled by the nerve cell. This works for the maintaining the balance between the reaction and action activity of bodies. The various afferent activity works because of nerve cell.

 3) Write short notes on the following.

(a) Cytoplasm

(b) Nucleus of a cell.

Ans: –

Cytoplasm: –   This cytoplasm present between the nucleus and the cell wall. This is jelly like substance. This includes the nucleus also with small cell.

Nucleus of cell: – The nucleus of cell controls the all activity which happens throughout the body of an organisms. There present various substance in a nucleus like chromosome, cytoplasm, mitochondria.

4)Which part of the cell contains organelles?

Ans:-The cytoplasm which present in between the cell wall and nucleus also a jelly like substance contains the organelles.

5)Make sketches of animal and plant cells. State three differences between them.

Ans: –

Plant cell

Animal cell

Cell wall present. Cell wall is absent
Plastid present Plastid absent.
Cell membrane is absent. Cell membrane is present.


6)State the difference between eukaryotes and prokaryotes.

Ans: –

Eukaryotes Prokaryotes
Cell doesn’t develop more. It is developed cell
Nuclear membrane is seen. Cell membrane is seen.
Mainly unicellular types cell organelles these types. Multicellular plant and animal in this type.

7) Where are chromosomes found in a cell? State their function.

Ans: –   In nucleus of a cell the chromosome is present.

This chromosome is the main reason behind the transfer of characteristics from parents’ cell to the new one. This chromosome differs the characteristics between the male and female.

 8)‘Cells are the basic structural units of living organisms. Explain.

Ans: –   As we all know that cell is the basic structural units of living of the organisms. This nucleus is forms with the various substance including in it which helps in the body growth. As this small substance is responsible for the whole body the cell called basic structural units of living organisms.

 9)Explain why chloroplasts are found only in plant cells?

Ans: –   The chloroplast is three types as Chromoplast, chloroplast and leucoplast. This chloroplast helps in photosynthesis process in the plant and as in animal there’s no scene of photosynthesis chloroplast is absent.

10)Complete the crossword with the help of clues given below.


  1. This is necessary for photosynthesis.
  2. Term for component present in the cytoplasm.
  3. The living substance in the cell.
  4. Units of inheritance present on the chromosomes.


  1. Green plastids.
  2. Formed by collection of tissues.
  3. It separates the contents of the cell from the surrounding medium.
  4. Empty structure in the cytoplasm.
  5. A group of cells.

Ans: –
