(a) -→ (iii) Vacuoles are the membrane-bound cell organelles present in the cell. These are larger in plant cells hence, the nucleus is towards the sides in a plant cell. This organelle is covered with a membrane called tonoplast. (b) -→ (v) The structure of a nucleus is covered with a membrane called the nuclear envelope. The nucleolus is the dense portion of the nucleus, contains the genetic material and formation of RNA takes place. (c) -→ (i) The lysosomes secrete 40 types of powerful digestive enzymes and helps in the intracellular digestion that can break lipids, proteins (body-building foods), carbohydrates, and nucleic acids. (d) -→ (iv) Anthocyanin is a type of natural plant pigment that dissolved in the cytoplasm. They are water-soluble, non-plastidial pigments that are dissolved in the cell sap. (e) --> (ii) The mitochondria are bounded by a double membrane. The inner membrane is folded into finger-like projections and have a surface area more than the outer membrane. This feature of cristae helps in the faster production of ATP during the final stages of cellular respiration by respiratory enzymes. <table class="MsoTableGrid" style="border-collapse: collapse; width: 500px; color: rgb(102, 102, 102); font-family: Roboto, sans-serif; font-size: 14px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: start; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; text-decoration-style: initial; text-decoration-color: initial; border: 1pt solid black;"> Column A Column B (a) Vacuoles (iii) Covered by tonoplast (b) Nucleolus (v) Forms RNA (c) Lysosomes (i) Intracellular digestion (d) Anthocyanin (iv) Dissolved in the cytoplasm (e) Cristae (ii) Respiratory enzymes

Given below are the sketches of two types of cells A and B. Which one of these is a plant cell? Give reason in support of your answer.

Plant cell contains both the cell wall and the cell membrane and also it has a large vacuole that pushes the nucleus towards the periphery. Hence, Figure B is the Plant cell.

Given below are the sketches of two types of cells A and B. List the cell structures which are common to both the types.

The plant and animal cell contains almost similar cell organelles except few. The cell organelles are present in the fluid part of the cell called cytoplasm. The cell membrane, ribosomes, nucleus, endoplasmic reticulum, lysosomes, Golgi body, and mitochondria are common to both the types.

Given below are the sketches of two types of cells A and B. Name the structures found only in plant cells and those found only in animal cells.

The cell organelles are present in the fluid part of the cell called cytoplasm. Both plant and animal cell contains almost similar cell organelles except few like plastids, and centrosomes. Plastids and the cell wall are found only in plant cells whereas centrosomes are found only in the animal cell.
