Biology Q1 Midterm on SOLS REVIEW
ria,nucleus,
ribosomes,E
r golgi,cell
membrane,
nucleolus,
cytoplasm
Plant
Chloroplast
Cell well
Large central
vacuole
1. Characteristics of animal and plant cells
Animal
Lysosome
centriole
2. Photosynthesis converts light energy into_sugar/food/high energy sugar/glucose
3. Calculating total magnification=objective # x eyepiece #
4. What makes a cell motile? cilila or flagella
5. Function of ribosomes:to make proteins
6. Function of mitochondrion----Energy-it turns food into energy with the
presence of oxygen(O2)
7. Regulates cell activities by increasing reaction rate----Enzymes-end in -ose
8. A function both carb’s and lipids share---storage of energy-carb’s 1st source of
energy
9. Protein’s monomer: amino acids
10. cell theory-inc. that cells are building blocks of life-and…all plants and animals
made of cells and new cells come from existing cells
11. Why do enzymes work with specific substrates? They connect and react at an
activation(active) site
12. –Compare eukaryotes and prokaryotes:
Prokaryotes-all
are bacteria
No nucleus and no
membrane-bound
organelles ,less
complex
Ribos
ome,
cell
memb
rane
DN
A
Eukaryotes-all organelles-like
mitochondria,ER,etc…
13. Properties of water-inc ability to dissolve many things
14. Macromolecule enabling insulation--lipids
15. “brain” of cell---nucleus
16. Organelle in both prokaryoetes and eukaryotes—ribosomes-which are NONmembrane bound

17. Which organelle should a muscle cell have plenty of---mitochondria
18. Organelles of photosynthesis and cellular
respiration:________________________________
19. Explain homeostasis:--internal balance necessary for organisms—like
temp.,pH,etc….
20. Autotrophs v, heterotrophs—Autotrophs(plants and algae main examplesz) make
their own food and heterotrophs don’t(animals-inc. humans,fungi,most protists
most bacteria)
21. Cell 1st defense-----cell membrane
22. benefit of ice floating on a winter lake---prevents it from freezing solid
23. reason one molecule will diffuse easier than another:smaller size slips through
membrane easier
24. Compare diffusion/osmosis in hypertonic---water out/cell size shrinks,hypotonic
–water in and size increases and isotonic—water comes in and out evenly and
size stays the same
25. Type of molecule that move larger molecules through cell membrane---channel)protein
26. Remember that photosynthesis and cellular respiration are basically opposite
---the reactants for one are the products of another and vice-verse
27. Enzymes speed up reactions and therefore control cell activities
28. Organelle of photosynthesis-chloroplast/organelle of making energymitochondria
29. Know that knowledge of cells would not have happened w/ microscopes and
work of Von Leewehoeck/Hooke
