muscle cells do not require energy from respiration. Have many mitochondria due to energy requirements. Gravity. Tags: Question 3 . Title: Cell Specialization Lab Author: Kalamazoo Public Schools Last modified by: Kalamazoo Public Schools Created Date: 2/15/2011 6:17:00 PM Company Why would this affect the heart? Biology. One cell cannot carry out all functions quick enough or effectively. Endoplasmic Reticulum. These cells are responsible for contracting and expanding in order to make the heart beat. The heads extend upward from a thick fiber made of many myosin tails wound together. Long thin cells. Blue Histology - Muscle.pdf. Nuclei are much more frequent and larger in smooth muscle and they are very; University of Waterloo ; BIOL 302 - Spring 2012. Specialization of cells. Delete Quiz. Cell Differentiation and Specialization. A muscle cell is a special kind of cell that makes up an organism's muscle tissues. Hair like structures are there to move or push substances along. Print; Share; Edit; Delete; Host a game. When many sarcomeres are doing this at the same time, the entire muscle contract. Endothelial cells: Flat cells that create overlapping regions to form the endocardium. to maximise absorption of water and mineral ions. The cells along the or windpipe have cilia, which look like hairs, to move trapped dust and particles up and out of the trachea.. Red Blood Cells. Animal. Key Concepts: Terms in this set (10) Specialized cells called _____cells help move the skeleton and help the heart beat and pump blood. EXAMPLES OF SPECIALIZED CELLS A. Once this happens, myosin can used the energy gained from ATP to crawl along the actin filament. Muscle Cell. Each sarcomere is a complex of proteins, which … Homework. This image shows the internal organization of a muscle cell. Most skeletal muscles are attached to bones by bundles of collagen fibers known as tendons.. A skeletal muscle refers to multiple bundles of cells joined together called muscle fibers. Cell Specialization Topic: Mechanisms Of Development. Where is a sperm cell found? Neuron. A. Actin and Myosin control contractions in the heart B. Each muscle fiber is formed from a chain of multinucleated muscle cells. Muscle Cells. The impulse is transferred to the nerve cell and travels down specialized canals in the sarcolemma to reach the transverse tubules. B1: CELL BIOLOGY . Plant. Animal cells are made up of many different elements: Such cells include muscle cell, sperm cell, apical meristem cells, and kidney cell. Muscle Cells. Muscle cell efficiency plays an important role in minimizing both excessive heat production as well as daily food requirements. Adipose cell, connective-tissue cell specialized to synthesize and contain large globules of fat. In general, these cells are characterized by having a large surface area which then increases surface area for absorption. 1. 13 pages. Xylem vessels: It transports water and minerals to the plant. 2.23). Which of the following will happen? 64% average accuracy. To allow them to do this they have multiple adaptations: - Contain mitochondria to transfer the energy needed for contracting. *. The contraction and relaxation of cardiac muscles cells cause the heart to pump blood throughout the body Stripe appearance and from short … ATS GCSE Biology - Cell Specialisation DRAFT. Long thin cells. A muscle cell, known technically as a myocyte, is a specialized animal cell which can shorten its length using a series of motor proteins specially arranged within the cell. Introduction The cells of muscle tissue are called muscle fibers. All cells are small because. A. xylem cells. RED BLOOD CELL (ERYTHROCYTE) A red blood cell is a tiny, disc-like cell (biconcave shape) which has no nucleus. Write. These are known as sarcomeres, and give skeletal muscle a banded or striated appearance. 3 years ago. Another specialized cells in animals are the muscle cells which generally have spindle-shaped cell body containing numerous mitochondria. One of the most fundamental questions in biology is how cells undergo specialization. Another large protein, titin, connects the Z plates together and prevents the sarcomere from being overstretched when it is not contracting.
