Question

(i) Name any three parts in plant cell which differentiate it from an animal cell and mention

their function.

(ii) Which organelle is known as the powerhouse of the cell? Why?​

Answer 1

Answer:

1) Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall

2) Mitochondria are tiny organelles inside cells that are involved in releasing energy from food. This process is known as cellular respiration. It is for this reason that mitochondria are often referred to as the powerhouses of the cell.

Answer 2

Answer:

(i) Cell wall in the characteristic feature of plant cell.

(ii) Chloroplast is found in plant cell which helps in photosynthesis in plants. Animals cannot synthesis their own food because chloroplast is not found in the animal cell.

(ii) Large vacuoles are found in plant cell which contains excretory waste of plant cell. Animal cell do not possess vacoules, if present these are of small size.
