Algae
Photosynthetic eukaryotes, from tiny cells to giant kelp.
Where is algae found
Everywhere with water
is algae a plant
No
where does 50% of the earth’s oxygen come from
Algae Via photosynthesis
what is a autotroph
an autotroph makes their own food using sunlight, like plants and algae
what are heterotrophs ?
heterotrophs cant make their own food and eat other organisms
what is ATP
Adenosine Triphosphate
what is ATP
Adenosine Triphosphate
what is the difference between ATP and ADP
ATP has more energy than ADP
what is GLUCOSE
glucose is a monosaccharide
what is photosynthesis
Plants use sunlight, water, and carbon dioxide to make food (glucose) and release oxygen.
what is cellular respiration
Cellular respiration is how cells turn food (glucose) and oxygen into energy (ATP), water, and carbon dioxide.
what is the structure of water
1 molecule: is made up of 2 hydrogens and bonded with 1 oxygen
what is a polar molecule
a molecule that has electrically charged areas
non polar substances?
doesn’t have charged ends
what is the plasma membrane ?
the gateway to the cell
what is diffusion?
Diffusion is when molecules move from where there’s more of them to where there’s less, spreading out evenly.
what is osmosis?
the movement of water from areas of high to low concentration through the membrane.
what are the 5 stages of the cell cycle ( 3 of the 5 together are interphase)
- G1
- S
- G2
- M
- C
what is the 4 mitotic stages (PMAT)
-Prophase
- Metaphase
- Anaphase
- Telophase
what does anaphase look like
fighting spiders
what does prophase look like
a big mess of spagetti
what does metaphase look like?
straight line
what does telophase look like?
split in half
