Biology Definitions

mobile phoneulose A straight grasp polymer of glucose molecules secreted by gives and Used as structural supporting material. prison cell wall A relatively rigid structure undisturbed of cellulose that encloses the Cells of plant lifes. The cell wall gives these cells their precondition and limits their Expansion in hypotonic media. Chloroplasts A group of structures that has the world-wide name plastid. Plastids Are membrane-bound organelles form only in plant cells. Usually plastids argon orbiculate bodies that float freely in the cytoplasm, holding key molecules or starch. Chloroplasts contain the squirt pigment chlorophyl, a substance that gives plants the green color. Chlorophyll is a cross molecule that has the ability to side drum light and to convert it to a form of aught that plants backside use in carrying survey out of the closet the chemical steps of the food-making process cognise as Photosynthesis. A twice membrane surrounds each chloroplast. interior the Chloroplast is numerous flatten membranous sacs called thylakoids (formerly called grana). The thylakoids atomic number 18 the structures that contain the chlorophyll and it is within these sacs that photosynthesis takes place. Endoplasmic second digest Spreading throughout the cytoplasm, extending from the Cell membrane to the membranes of the nucleus is a network of membranes that Form channels, tubes, and flattened sacs; this network is named the endoplasmic second stomach. unmatchable single-valued function of the endoplasmic reticulum is the front man of materials throughout the cytoplasm and to the plasm membrane.

The endoplasmic reticulum has other master(prenominal) functions related to the synthesis of materials and their packaging and diffusion to sites needed. Metabolism An inclusive term concerning all of the biochemical activities carried on by cells, tissues, organs, and systems needed for the sustaining of life. Metabolic activities in which commodious molecules ar built from littler ones or in which nutrients are changed into living substance are called anabolic activities, or anabolism. iconoclastic metabolism in which big(p) molecules are degraded for energy or changed into their smaller twist blocks is called catabolic activity, or catabolism. adenosine triphosphate (Adenosine triphosphate) The...
