Answer 1

Answer:

Hope it helps you my dear friend.❤

Explanation:

1. Chloroplast is called kitchen of the cell because photosynthesis takes place in chloroplast. Photosynthesis is the process by which green plants prepare their own food with the help of sunlight,minerals and water.

2.Exocytosis is a form of active transport and bulk transport in which a cell transports molecules out of the cell by secreting them through an energy-dependent process.

3.In secretory cells, such as the secretory cells of endocrine glands, organelles related to the production, processing and “export” of substances are widely present and well-developed. These organelles are the rough endoplasmic reticulum and the Golgi apparatus.

4.Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components. All of these components work together in order for the nucleus to accomplish all of its functions.

5.The nucleoplasm has a complex chemical composition, it is composed mainly of the nuclear proteins but it also contains other inorganic and organic substances such as nucleic acids, proteins, enzymes and minerals. ... The most important basic proteins of the nucleus are nuclear proteins and the nucleo histones.
