Life science Name : Anna Vanessa Valenzuela ID # : 284661 Course: Life Science,the science of life Teacher : Module : Biolog Activity : Exercise 3 Date :Tuesday 22 March,2019 Bibliografy : (APA Format) 1. Look for 15 representative images of the eukaryotic cell of animal and vegetal origin; also, look for the illustrations of each one. 2. Locate your images in a comparative chart and point out the function of each part of the cell. 3. In the comparative chart, place the image and indicate the part of each cell using lines.
Life science Nissl bodies, and the mitochondria. plant collenchyma cells Angular collenchyma; thickening is located at the edge or pheripheral part. Lamellar collenchyma; thickening is located at the tangential side. Lacunar collenchyma; thickening is located in the intracellular spaces. The thickened walls of the collenchyma cells enable them to provide additional support to the areas where they are found. Most notably, collenchyma cells serve growing parts of the plant, such as shoots and leaves, both by providing support and by filling in vacant spaces that will be used for later growth.
Life science plant Dermal cell Cuticle: the outer walls of epidermal cells are covered with a waterproof cuticle made of a fatty material called cutin. Trichomes: single or multi-celled outgrowths of epidermal cells (hairs or scales), deter animals and insects and, is some plants, humans. Protects the soft tissues of plants and controls interactions with the plants' surroundings. plant Sclerenchyma cells Lignin: Provides hardness to them. The major function of sclerenchyma is support and structure.
Life science plant Parenchyma Cellulose: Is the substance that makes up most of a plant's cell walls Hemicellulose: Are synthesised from sugar nucleotides in the cell's Golgi apparatus. Calcium pectate: Calcium holds the cell walls of plants together. It also activates specific plant enzymes, which send signals to the plant cells that coordinate certain growth activities. Parenchyma cells huge carry amounts of chloroplasts, ribosomes, ER, and Golgi bodies. Depending on what type, they may carry starch, proteins, fats, pigments, and even crystals.
Life science plant Stem cell Epidermis: It protects against water loss, regulates gas exchange, secretes metabolic compounds.
