Match the following: Column 1 Column 2 A. Plasma membrane (i) Cells of common origin B. Cell wall (ii) Nucleus and cytoplasm C. Protoplasm (iii) Prevents the bursting of cells D. Cytoplasm (iv) Maintains homeostasis E. Tissue (v) About 90% of water

A-(iv) The plasma membrane maintains homeostasis. Homeostasis is defined as the stability, balance, or equilibrium within a cell or the body. B-(iii) The cell wall helps in preventing the bursting of cells. It is a structure that surrounds the cytoplasm of a cell. C-(ii) The protoplasm consists of a nucleus and cytoplasm. The protoplasm that surrounds the nucleus is called the cytoplasm and the protoplasm present inside the nucleus is called the nucleoplasm. D-(v) The cytoplasm is made up of 90% water. It contains organelles such as mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, etc. E-(i) The tissues are a group of cells that have a common origin that gives rise to organs and organ systems. Column 1 Column 2 A. Plasma membrane (iv) Maintains homeostasis B. Cell wall (iii) Prevents the bursting of cells C. Protoplasm (ii) Nucleus and cytoplasm D. Cytoplasm (v) About 90% of water E. Tissue (i) Cells of common origin

Match the following: Column 1 Column 2 A. Mitochondria (i) Harness sunlight B. Ribosome (ii) Food storage C. Endoplasmic reticulum (iii) Cellular respiration D. Chloroplast (iv) Intercellular transport E. Leucoplast (v) RNA

A- (iii), Mitochondria is the site for cellular respiration thereby releasing energy in the process. B- (v), Transcription is the synthesis of RNA that is transferred to the ribosomes for the synthesis of proteins. C- (iv), The endoplasmic reticulum is the intercellular transport system of the cell. D- (i), The chloroplast helps in the trapping of solar energy during photosynthesis. E- (ii), Leucoplast is a cell organelle that helps in storing food materials. Column 1 Column 2 A. Mitochondria (iii) Cellular respiration B. Ribosome (v) RNA C. Endoplasmic reticulum (iv) Intercellular transport D. Chloroplast (i) Harness sunlight E. Leucoplast (ii) Food storage

Match the following: Column 1 Column 2 A. Production of melanin (i) Lysosomes B. Storage of sugars (ii) Golgi complex C. Digestive bags of cells (iii) Centrosome D. Cell division regulation (iv) Vacuoles

A- (ii), The Golgi complex is involved in the production of melanin. It is made up of a series of flattened, stacked pouches called cisternae. It plays an important role in the packaging of proteins. B- (iv), Vacuoles are responsible for the storage of dissolved materials such as sugars, amino acids, etc. C- (i), Lysosomes are called digestive bags of the cell. They contain digestive enzymes that break down worn out parts of the cell. D- (iii), The centrosome initiates and regulates the cell division. They are made up of two centrioles and their main function is to organize the microtubules. Column 1 Column 2 A. Production of melanin (ii) Golgi complex B. Storage of sugars (iv) Vacuoles C. Digestive bags of cells (i) Lysosomes D. Cell division regulation (iii) Centrosome
