Plant Growth and Development Topic 1. 1: plant tissues and their function

Learning Outcomes from this powerpoint • Know the structure and function cell components

Vacuole • Isolating materials that might be harmful or a threat to the cell. • Containing waste products. • Containing water in plant cells. • Maintaining internal hydrostatic pressure or turgor within the cell. • Maintaining an acidic internal p. H. • Containing small molecules.

Endoplasmic Reticulum • Proteins which are synthesised by the cell and then released into outer medium of the cell are called secretory proteins. Examples of secretory proteins include mucus, digestive enzymes and hormones. • The ER produces transmembrane proteins and lipids

Golgi Apparatus

Golgi Apparatus • It has been likened to the cell's post office. A major function is the modifying, sorting and packaging of proteins for secretion. It is also involved in the transport of lipids around the cell, and the creation of lysosomes

Mitochondria creates • Mitochondria are the main sources of energy for each cell, and therefore for the plant as a whole. The process for converting raw nutrient materials into usable energy is known as cellular respiration. While energy production is the main function of the mitochondria, they also perform other services for a cell.

Nucleus • This organelle has two major functions. It stores the cell's hereditary material, or DNA, and it coordinates the cell's activities, which include intermediary metabolism, growth, protein synthesis, and reproduction (cell division). Only the cells of advanced organisms, known as eukaryotes, have a nucleus.

Cytoplasm • Cytoplasm contains molecules such as enzymes which are responsible for breaking down waste and also aid in metabolic activity. Cytoplasm is responsible for giving a cell its shape. It helps to fill out the cell and keeps organelles in their place.

Cell Wall • The cell wall is the protective, semi-permeable outer layer of a plant cell. • A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.
