Important Questions of this chapter: **Definition Cell cycle 2. Homologous Chromosome 3. Sister Chromatid 4. Synapsis **Short Questions 1.Describe the chief events of mitosis and show how these differ from meiosis. (V.V.I.) 2. What ‘checkpoints’ occur in cell cycle? What is the role of each? **Long Questions 1.Describe the phases of the cell cycle and the events that characterize each phase. Answer of short Definition is given below 1. Cell Cycle: The cell cycle is an orderly
Premium Cell cycle Mitosis
Increase size = decrease SA: Volume * Ratio decreases = exchange decreases * Limits cell size for efficiency * Rate of heat/waste production + nutrient consumption = function of volume * Exchange rate = function of SA 2.1.7 – Multicellular organisms show emergent properties * Whole is greater than the sum of its parts 2.1.8 * Nucleus – DNA – chromosomes – genes * Differentiation occurs when genes are “switched on” = determines development * Differences

life Cell division is reproduction at the cellular level requires the duplication of chromosomes sorts new sets of chromosomes into the resulting pair of daughter cells Cell division is used: for reproduction of single-celled organisms growth of multicellular organisms from a fertilized egg into an adult repair and replacement of cells sperm and egg production Living organisms reproduce by two methods: Asexual reproduction produces offspring that are identical to the original cell or organism involves

can make copies of themselves. A cell is also a metabolic compartment where many different chemical reaction occur. There are two types of cells‚ eukaryotic and prokaryotic. Prokaryotic cells are usually unicellular‚ while eukaryotic cells can either exist as a single celled organism or be found in multicellular organisms. The unicellular and multicellular organisms are linked to cell size and surface area to volume ratio. The experiment for cell size and diffusion was set to see how and how much water

termites‚ butterflies‚ penguins‚ hummingbirds‚ starfishes‚ and sand dollars. These species not only divide upon the two the same equivalence in characteristics‚ setting them apart from other species‚ but includes the fact that all are generally eukaryotic‚ multicellular‚ heterotrophic‚ lack cell walls‚ are motile‚ and usually pass through a blastula stage as animals. Elephants and armadillos are just two species out of the vast majority of existing mammals. These two share the same characteristics: warm-blooded;

Christopher Scott Biol 241 homework Professor: Greg Crowther 1. Compare and contrast the reasons cell division is important for unicellular and multicellular organisms. Cell division is the method in which single celled organisms reproduce. Cell division allows multi-cellular to grow and repair dead or damaged cells 2. Provide an example of why cell division remains important to an adult organism even after it isfully developed. Some cells divide to heal wounds such as cuts or broken bones.

Rizal Technological University Investigatory Study (Kingdom Animalia) Written by: Rodette Joyce Laurio Submitted to : 1 Introduction In biology‚ kingdom is a taxonomic rank‚ which is either the highest rank or in the more recent three-domain system‚ the rank below domain. Kingdoms are divided into smaller groups called phyla (in zoology) or divisions in botany. When Carl Linnaeus introduced the rank-based system of nomenclature into biology‚ the highest rank was given the name
