Lab Practical 1- Biology

Exercise 4, 6, and 9

Cytology

Study if cellular structure and function

Prokaryotes do not have a

membrane-bound nucleus

Eukaryotes have

membrane-bound nuclei

What type of cell is this

Prokaryotes

This animal cell is classified as a

Eukaryotes

Main difference between Prokaryotic and eukaryotes cells (3 of them)

Nucleus, DNA, Organelles

Main similarities between prokaryotic and eukaryotes cells (4 of them)

Plasma Membrane, Cytoplasm, Ribosomes

Give three Eukarototes cell examples

Animal, Plants, Fungi

Give 2 examples of Prokaryotic cells

Bacteria, archaea

What type of cell is this (E or P)

Prokaryotic

How to know if I cell is Pro (Prokaryote)
it doesn’t have….

a nucleus, a membrane

What is the largest Prokaryotes

Cyanobacteria

This is a Cyanobacteria cell which is classified as a

Prokaryote

Cyanobacteria possess chlorophyll which is used for

Photosynthetic

This is a cyanobacteria cell but more specifically it is a

Oscillatoria cell

Describe Filamentous

Elongated Cell structures

Is either Oscillatoria or Gleocapsa filamentous (elongated cell structure)

Oscillatoria

This shows a Cyanobacteria but is a

Gleocapsa

What do tiny bacteria lack

chlorophyll

What are two examples of tiny bacteria

Lactobacillus and Sterptococci

Streptococci is found in

yogurt

Which tiny bacteria is shown here

Lactobacilli’s

This bacterium is commonly found in yogurt what is it and what type of broad cell is it

Streptococci, Prokaryotic Cells

Cocci are what shape

Round/spherical

Bacilli are what shape

Elongated and rod shaped

This is a example of Bacilli or cocci

bacilli

Prokaryotic cells have

Cell membrane, Cytoplasm, Nucleoid, Pilus, RObosome’s, Cell wall,

When talking about ANIMAL cells what does the plasma membrane do

controls substance of going in and out of the cell

When talking about ANIMAL cells what does the Ribosome do

making Polypeptides

When talking about ANIMAL cells what does the Lysosomes do

Decides what is kept and thrown out (like garbage truck)

When talking about ANIMAL cells what does the Nuclear Envelope do

encloses the nucleus

When talking about ANIMAL cells what does the Nucleus do

stores genetic material

When talking about ANIMAL cells what does the Nuclear Pore do

Is a passageway for molecule info to get to the nucleus

When talking about ANIMAL cells what does the Rough ER do

Site or protein sorting and secretion

When talking about ANIMAL cells what does the Smooth ER do

Detoxifies and makes lipid

When talking about ANIMAL cells what does the Mitochondrion do

Site ATP production

When talking about ANIMAL cells what does the cytoskeleton do

Protein filaments that provide shape aid in movement

When talking about ANIMAL cells what does the Peroxisome do

Break down hydrogen peroxide and other harmful molecules are broken down

When talking about ANIMAL cells what does the Golgi Apparatus do

site of modification sorting and section of lipids and proteins

When talking about PLANT cells what does the CHLOROPLAST

Site of photosynthesis

When talking about ANIMAL cells what does the CYTOSOL do

site of many metabolic pathways
