At-Home Learning Packet instructions for Mansfield Senior High Biology covering work from March 17 to April 6. The packet directs students to complete Chapter 11 and Chapter 12 study guides, review cell division materials, and finish multiple handouts including mitosis vs. meiosis and Mendel and Meiosis. It also emphasizes reading ahead on DNA structure, completing labeled vocabulary definitions, checking Pearson online, and preparing to submit all assignments on return.

Mansfield City Schools At Home Learning Packet | School: | Mansfield Senior High | | --- | --- | | Grade: | Biology | | Teacher: | Lawless-Week 1&Week 2 | BIOLOGY INSTRUCTIONS FOR 3/17-4/6 Checklist: Take YOUR textbook home to help complete the following packets: Lesson 11.3 and Lesson 11/4 Study quide.We have already completed 11.1 and 11.2Read Chapter 12 and complete the Study Guide for Chapter 12. Be prepared to turn in both Chapter 11 and Chapter 12 Study Guide upon return,April6th. Read and highliqht Cell Division and complete questions on the handout.Turn in uponreturn.(the following handouts are from another source,and chapters/sections are notlabelled according to your text,so go by topic,not chapters on the handout). Read the Chapter 12 summaries for lessons 12.1-12.4.p.402-403 and define the vocabularyfor each section.Turn in the definitions only,labeled and numbered for each section.Turn inupon your return April 6th.(Understanding the terms will make life sooooo much easier foryou for the upcoming chapters and tests!!!!). Complete the Mitosis and cvtokinesis handout.Turn in upon return April 6th. Look over the diagram of Comparing Mitosis and Meiosis,and use to help complete Mendel andMeiosis). Complete the handout labeled Mendel and Meiosis Chapter 10.Aaain.this is from a differentsource.so vou will have to read Chapter 12 in vour text to help Complete.Do vour best,and wewill go over this handout together upon your return. The handout"Monohvbrid Cross"is to help vou visualize the differences between Mitosis andMeiosis,Do your best to complete p.28 on this handout. Read over the handout labeled DNA Structure.This is a look ahead to Chapter 13.DNA.although the handout is from an older text.Look it over.Do vour best to complete p.62.55. 64.66.68.and 72.Leave blank what vou cannot find or do not understand well enouah tocomplete.This is detailed material,but it will go smoother and faster for you when we return,ifyou have at least tried to read Chapter 13 and complete as much as you can. Check Pearson on-line for any supplemental assignments.At this time,I am just planning to dothe packets,but if I feel there are assignments that would be helpful,I will assign them (just tohelp you understand,they will probably be a grade item with time to work on in class upon yourreturn). THE CELL CYCLE CELL CYCLE---the regular sequence of growthand division.See p.66. Two main sections to the cell cycle: # 1.Interphase --cells grows to mature size (doubles thecytoplasm and duplicates organelles such asmitochondria,chloroplasts,ribosomes,andenzymes --cell makes a copy of its DNA(process calledreplication). --prepares to divide into two cells (producesstructures to help cell divide) # 2.Mitosis --cell's nucleus divides in two.The DNAstrands(1 original,1 copy)separate into different daughter cells.There are 4 steps inmitosis:prophase,metaphase,anaphase,teleophase,and is followed by cell division(cytokinesis). PROPHASE—chromatin condenses/coilsforming the familial chromosome (doubledstrands exactly alike,which are held togetherby a CENTROMERE.Each half is called aCHROMATID). METAPHASE-chromosomes line up at thecenter of the cell.Each chromosome attachesto a SPINDLE FIBER at the centromere. ANAPHASE-centromeres split and thechromatids separate.Each chromatid movestoward opposite ends of the cell. TELEOPHASE-chromosomes uncoil.Nuclear membrane reforms. CYTOKINESIS-cell membrane pinches inaround the middle,divides the cell into twoDAUGHTER cells.Each daughter receives V₂the organelles and cytoplasm,and one of thetwo identical DNA strands. DNA REPLICATION REPLICATION-process of cell copying DNAbefore mitosis.Ensures that each daughtercell has all the instructions for cell functionsthat are held in the DNA code. DNA STRUCTURE:looks like a twisted ladderwith the"sides”and "rungs"constructed ina specific way: Ladder sides:made up of a SUGAR (DEOXYRIBOSE),alternatin

FAQs

What assignments must be completed by April 6?

Finish the Chapter 11 and Chapter 12 study guides, complete the cell division and related handouts, and turn in the labeled vocabulary definitions and completed pages referenced in the packet.

What are the two main parts of the cell cycle described in the packet?

The packet lists Interphase and Mitosis as the two main sections of the cell cycle, followed by cytokinesis as part of cell division.

How does the packet explain DNA replication and DNA structure?

DNA replication is copying DNA before mitosis so each daughter cell has the instructions in the DNA code. DNA structure is described as a twisted ladder with sugar-phosphate sides and nitrogen base rungs that pair specifically (A with T, G with C).
