EVERYDAY SCIENCE

Detailed explanation-1: -The organelles found only in plant cells include chloroplast, cell wall and a vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.

Detailed explanation-2: -Typical components of the cell wall include cellulose, non-cellulosic, and pectic polysaccharides, proteins, phenolic compounds, and water.

Detailed explanation-3: -Chloroplasts are found in plant cells, but not in animal cells. The purpose of the chloroplast is to make sugars that feed the cell’s machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating sugars.

Detailed explanation-4: -The cell wall is present only in plant cells but not in animal cells because they provide rigidity and support to plants. The cell wall provides definite shape, strength, and protection against mechanical stress and physical shocks. It helps to control cell expansion due to the intake of water.
