DENDROLOGY

Detailed explanation-1: -Examples of organelles are the nucleus (a structure that contains the cell’s chromosomes and is where RNA is made), mitochondria (structures that make energy for the cell), and lysosomes (sac-like containers filled with enzymes that digest and help recycle molecules in the cell).

Detailed explanation-2: -An example of a nucleus in real life is the nucleus of human skin cells. The nucleus contains all of our genetic information and only genes that are necessary for skin cells are expressed, thus producing the unique cell type needed for the epidermis.

Detailed explanation-3: -Nucleus. The nucleus is a double-membraned organelle found in all eukaryotic cells. It is the largest organelle, which functions as the control centre of the cellular activities and is the storehouse of the cell’s DNA. By structure, the nucleus is dark, round, surrounded by a nuclear membrane.

Detailed explanation-4: -Some of the major organelles include the nucleus, mitochondria, lysosomes, the endoplasmic reticulum, and the Golgi apparatus. Plant cells also include chloroplasts, which are responsible for photosynthesis.
