Question

1. a) what is a mutation? c-2 b) list two mutagens. c-2 6. complete the sentences c-6 a. organelles are located in __ b. the largest organelle in a plant cell is the c. dna inside the cell is found in the d. proteins are made by e. animal cell lacks f. the power plant of the cell is called__

Explanation:

a) A mutation is a permanent change in the DNA - sequence of a gene or an organism's genome. It can occur spontaneously or be induced by mutagens.
b) Mutagens are agents that cause mutations. Two common mutagens are ultraviolet (UV) radiation (a physical mutagen) and certain chemicals like nitrous acid.
6a) Organelles are located in the cytoplasm of a cell. The cytoplasm is the gel - like substance within the cell membrane that contains all organelles and cell parts.
6b) The largest organelle in a plant cell is the vacuole. It can occupy a large portion of the plant cell's volume and has functions like storage and maintaining turgor pressure.
6c) DNA inside the cell is found in the nucleus in eukaryotic cells. The nucleus is the control center of the cell that houses the genetic material.
6d) Proteins are made by ribosomes. Ribosomes are the sites of protein synthesis in the cell, where they translate mRNA into polypeptide chains.
6e) Animal cells lack a cell wall. Plant cells have a rigid cell wall made of cellulose, which provides structure and support, while animal cells rely on other mechanisms for shape and support.
6f) The power plant of the cell is called the mitochondria. Mitochondria are responsible for cellular respiration, generating ATP (energy) for the cell.
