8D Unicellular Oraganisms
what is the 7 life proccesses (MRS GREN)
Movement, Reproduction, Sensitivity, Growth, Respiration, Excretion and Nutrition
8D Unicellular Oraganisms
Define multicellular and unicellular organisms
multicellular: Organisms made up of more than one cell
unicellular: Organisms made up of one cell
8D Unicellular Oraganisms
which of the 5 kingdoms are unicellular and witch are multicellular
Prokaryotes: Unicellular
Protoctists: Mostly unicellular
Fungi: Mostly multicellular
plants: Multicellular
animals: Multicellular
8D Unicellular Oraganisms
give an example for all the 5 kingdoms
8D Unicellular Oraganisms
what cell parts do Animals have
Cytoplasm
Cell membrane
Nucleus
Mitochondria
8D Unicellular Oraganisms
what cell parts do plants have
Cytoplasm
Cell membrane
Nucleus
Mitochondria
Cell wall
Chloroplasts
8D Unicellular Oraganisms
what cell parts do Fungi have and give an example of a fungi
Cytoplasm
Cell membrane
Nucleus
Mitochondria
Cell wall
[Yeast]
8D Unicellular Oraganisms
what cell parts do Protoctists have
Cytoplasm
Cell membrane
Nucleus
Mitochondria
(Cell wall) some
(Chloroplasts) some
[Seaweed]
8D Unicellular Oraganisms
what cell parts do Prokaryotes have
Cytoplasm
Cell membrane
Cell wall
[Bacteria]
8D Unicellular Oraganisms
define viruses structure from outer to inner and give an example of a virus
-Protein molecules in the fat envelope
-fat envelope
-protein coat
-strands of genes
[Influenza virus]
8D Unicellular Oraganisms
How do Viruses live and reproduce
8D Unicellular Oraganisms
how do yeasts reproduce and what fctors help them do that
by a proccess called budding (asexual reproduction) in which a daughter cell grow out a parent cell which are biologically identical
-Moisture
-Sugar
-Warmth
8D Unicellular Oraganisms
how do yeast respire (equations)
yeasts do aerobic (with oxygen Glucose + Oxygen → Carbon dioxide + Water) releasing more energy and anaerobic (without oxygen Glucose → Ethanol + Carbon dioxide) respirations producing less energy
8D Unicellular Oraganisms
how are yeasts used in baking
by putting Yeasts in the dough stretch and fold it letting air in the Yeast would respire aerobically and bubbles of gas make the dough rise
8D Unicellular Oraganisms
how would a yeast cell’s populaton’s growth curve’s line graph look like
The line starts slow, gets steeper as the population grows and more budding occurs but then levels off as resources run out and reproduction slows and stops
8D Unicellular Oraganisms
define the equation for when anaerobic bacteria respire
anaerobic respiration by the equation:
glucose → Lactic acid
producing some energy
8D Unicellular Oraganisms
how do bacteria reproduce and what factors help them
by a proccess called Binary fission where one cell grows and split into 2 identical parts while the factors of nutrients (such as sugar) warmth and moisture
8D Unicellular Oraganisms
why and how are anaerobic bacteria used to make yogurt and cheese
because the lactic acid they produce could be used to turns milk sour and thick (yogurt) also used to make sour milk a key ingredient used for cheese
8D Unicellular Oraganisms
name the parts of bacteria’s and their functions
(LOOK IN BOOK DIAGRAM FOR THIS)
8D Unicellular Oraganisms
how do algae produce organic molecule (equation)
using photosynthesis to produce organic molecule:
Carbon dioxide + Water → Glucose + Oxygen
by traping energy using the chlorophyll joined by carbon dioxide and water to make glucose add oxygen
8D Unicellular Oraganisms
name and define the functions of common parts of protoctist cells

8D Unicellular Oraganisms
what does a pyramid of numbers and biomass show
Pyramid of numers: represents the amount of organisms at each trophic point
Pyramid of biomass: represents the mass of all organisms at each trophic point
8D Unicellular Oraganisms
why may the bars not seem like a pyramid in the pyramid of numbers
8D Unicellular Oraganisms
why do the bars get smaller at higher trophic points
