Match the following cell types with their corresponding characteristics:

Prokaryotic Organisms = No nucleus, No membrane-bound organelles, Mainly unicellular, Cells are primitive compared to Eukaryotes Eukaryotic Organisms = Nucleus is present, Membrane-bound organelles are present (mitochondria/chloroplasts), Mainly multicellular, Cells are bigger and more complex than prokaryotes

Match the following types of microscopes with their descriptions:

Simple Microscope = Uses one lens to magnify an object Compound Microscope = Uses two or more lenses to magnify an object Transmitting Electron Microscope (TEM) = Sends electrons through objects and reveals the most detail Scanning Electron Microscope (SEM) = Photographs reflected electrons from surfaces and reveals 3D structures

Match the following cell structures with their corresponding organisms:

Includes bacteria i.e., members of the kingdom Monera = Prokaryotic Organisms Includes animals, plants, and fungi except Monera = Eukaryotic Organisms Extremophiles are prokaryotes which live in extreme environments = Prokaryotic Organisms

Match the following steps with the correct order of the practical of using a light microscope to view plant and animal cells:

Place the stained sample slide on the stage = Step 10 Secure the slide in place using the two spring clips = Step 11 Turn on the light or adjust the mirror = Step 12 Select the low-power objective lens (x4) = Step 13 Signup and view all the answers

Match the following parts of the microscope with their functions:

Part A = Bringing the image into focus using the coarse focus wheel Lens E = Marked 10× Lens O = Marked 40× Coverslip = Used to protect the lens Signup and view all the answers

Match the following animal cell preparation steps with their descriptions:

Obtaining a sample of cells = Swabbing the inside of the mouth using a cotton wool bud Using the coverslip = Lowering it from a 45o angle using a mounted needle Applying the stain = Using a dropper to add the methylene blue to the slide Applying the cover slip = At a 45o angle to the slide using a mounted needle Signup and view all the answers

Match the following components of a cell with their functions:

Ribosome = Protein Synthesis Cell membrane = Controls entry and exit of molecules Nucleus = Contains the cell's genetic material Mitochondria = Powerhouse of the cell, generates energy Signup and view all the answers

Match the following cell structures with their functions:

Nucleolus = Provides the individual components for ribosomes Chromosomes = Hold the genetic code for making proteins Mitochondrion = Produces almost all the energy required by the cell Vacuoles = Temporary storage of food, water, salts, pigments, and excretory products Signup and view all the answers

Match the following cell structures with their descriptions:

Chloroplasts = Double membrane structures that contain chlorophyll and DNA Cell wall = Made of cellulose and controls cell growth and shape Ribosomes = Small granular structures made of RNA and protein, involved in protein synthesis Nucleolus = Darker staining areas within the nucleus that provide the individual components for ribosomes Signup and view all the answers

Match the following cell processes with their locations:

Photosynthesis = Chloroplasts Respiration = Mitochondrion Protein Synthesis = Ribosomes DNA Coiling = Chromosomes Signup and view all the answers

Match the following cell structures with their characteristics:

Mitochondrion = Consists of a smooth outer membrane and a folded inner membrane with cristae Chromosomes = Made of DNA and proteins, and consist of two chromatids joined by a centromere Vacuoles = Usually only one in plants, very large and permanent Cell wall = Secreted by cell membrane, made of cellulose, and adjacent cells are cemented together by the middle lamella of pectin Signup and view all the answers

Match the following parts of a light microscope with their functions:

Eyepiece = This lens magnifies the image Objective lenses = Magnify the image. Low power (x4), medium power (x10), high power (x40) Body tube/barrel = Holds the eyepiece at one end and the revolving nosepiece (objective lenses) at the other end Stage = Platform on which the slide is placed Signup and view all the answers

Match the following cell structures with their functions:

Cell Membrane = Holds in cell contents and controls entry and exit of molecules Cytoplasm = Contains the entire contents of the cell inside the cell membrane, except the nucleus Nucleus = To control all cell activities and contains genetic material Nuclear Pores = Allow substances to enter and leave the nucleus Signup and view all the answers

Match the following characteristics with the correct type of microscope:

Uses light rays & focuses them with more than 2 convex lenses to illuminate an object = Light Microscope Uses a beam of electrons & focuses them with electromagnets to illuminate an object = Electron Microscope Magnifies up to 1400X = Light Microscope Magnifies up to 500,000 X = Electron Microscope Signup and view all the answers

Match the following cell types with their characteristics:

Plant Cell = Contains chloroplasts and a large, permanent vacuole Animal Cell = Does not have a cell wall or chloroplasts, and has small, non-permanent vacuoles Cell Ultrastructure = The components of the cell that are only visible using an electron microscope Cell Membrane = A fluid phospholipid bilayer coated and embedded with protein Signup and view all the answers
