statement is incorrect?
oplastids are present in animal cell
O Mitochondria has its own DNA
O None of the above​

Answer 1

[(a) Plastids are present in animal cells . ]

The above sentence is incorrect .

Plastids are only found in plant cells which is used for storage . There are 3 types of plastids :

1. Chloroplast - Green in colour . One that helps in photosynthesis
2. Leucoplast - Storage
3. Chromoplast - Other colours that are especially found in petals to attract insects.

Supplementary information :

• Mitochondria has its own DNA

→ Mitochondria has its own DNA hence also called as Semi Autonomous body.

Answer 2

★ QUESTION :

Which of the following statement is incorrect ?

(i) Plastids are present in animal cell.

(ii) Mitochondria has its one DNA.

(iii) None of the above

ANSWER :

The following statement which is incorrect in the above given options are :

(i) Plastids are present in animal cell.

━━━━━━━━━━━━━━━━━━━━━━━

JUSTIFICATION :

➠ Yes....The above given option (i) is incorrect because as we know that – 'Plastids are found in plant cell.'

Here, we have selected the (i) option because

★ What is the difference between plant cell and animal cell ?

The plant cell generally have a definite shape due to a rigid cell present around them. In comparison, animal cell have a cell membrane as their outer cover. This provides flexibility to the animal cell ; hence they can show a large variation in their shapes. Moreover, plant cells have plastids present in them ; whereas these are absent in the animal cells. Plant cell generally have large vacuoles ; animal cells, on the other hand, other lack of vacuoles or have very small vacuoles present in them.

★ What is plastids ?

Plastid are present in plant cell and these may contain pigment which help in photosynthesis and are responsible for imparting colour to fruits, vegetables and flowers.

★ What is mitochondria ?

Mitochondria is a rod shaped structure which is present inside the cell ; these help in the cellular respiration and production of energy.
