Oh no sciencey words
Mitochondria and Friends
Thinking Bigger
Cells? that's my speciality
Who knows?
100
What are those little dots that float around in the cell?
Extra points: what do they spend their time making?
ribosomes.
they read DNA instructions from the nucleus and use it to make proteins.
100
whats the name of the thing that acts like the 'skin' of the cell, keeping the inside and outside separate?
the cell membrane or plasma membrane. either works.
100
are these animal cells or plant cells?
plant cell
100
What type of cell is this:
extra points: what is its role in the body:
its a sperm cell. It has to move to transport DNA (genetic material) and fertilize egg cells.
100
On this graph of my caffeine intake today, what is the Independent and Dependent variables?
independent is time
dependant is caffeine.
you need both for one set of points.
125
Yolks (the big yellow things) are actually what type of organelle?
Extra points: what's their role in the cell?
the nucleus.
its the control centre. it holds DNA and manages cell activity.
125
What are those green things
Extra points: what do they do?
chloroplasts.
They photosynthesize (use sunlight to turn water and carbon dixoide into sugar and oxygen)
125
what type of cells are these?
plant cell (see the cell walls?)
125
What type of cell is this?
Extra points: what is its role in the body?
Guard Cells
It can open and close to let gases in and out
125
According to this graph of my caffeine intake today, roughly how much caffeine am i working with RIGHT NOW. Like, at this very moment.
idk its probably like 100mg. The class can decide if the answers close enough.
150
What is this (hint: its NOT a vacuole)
Extra points: What is its role in the cell?
Lysosome
they hold digestive enzymes that break things down
150
What organelle is this?
Extra points: what does it do?
Mitochondria. The powerhouse of the cell.
It turns sugar into energy
150
Why do plants need this whole thing?
plants need a cell wall because they dont have bones. Cell walls are what gives them structural support
150
What's this thing?
Extra points: What is its role in the body?
root hair cell
it absorbs and holds lots of water with its large vacuole
150
Is that a plant cell or an animal cell?
animal cell (its a white blood cell hunting down a bacteria)
175
Why does this thing need so many mitochondria?
mitochondria make energy. This cell needs to move around, so it needs lots of energy
175
What's the transparent stuff cells are filled with?
Extra points: What is its role in the cell?
cytoplasm
all the organelles are supported by it, and it contains materials needed for cellular processes.
175
plant or animal?
animal (its a mutated red blood cell)
175
What is this cell.
Extra points: What is its role in the body?
neuron / nerve cell
it transmits nerve signals
175
This slug is called Elysia Chlorotica. She likes eating plants and collecting. What does she collect and why?
she collects chloroplasts from the plants she eats (the green dots) and then uses them to photosynthesize
200
What three organelles do plants have that animal cells dont have?
chloroplasts
cell walls
BIG vacuoles
200
What organelle is this (bottom right)
extra points: What are the little dots?
Endoplasmic Reticulum.
Extra points: ribosomes
200
why do these guys have so many little grabby things?
they're neurons. They transmit nerve impulses through the body. they have long tails (called axons) to transmit the signal. Just like how metal cables transmit electricity between power poles.
200
what type of cell is this?
Extra points: what is its role in the body?
Red Blood Cell
It transports oxygen around the body
200
What type of cell is this?
bacteria cell!
Its not a plant cell. it DOES have a cell wall, but otherwise its only organelle is ribosomes (no nucleus, chloroplasts, etc)
