Biology HELP?

Question

My biology instructor insists that we learn the definintion of alot of words on our study guide; however, we are also to learn the concept of these words and I am having trouble. There is so much information out there on these and I could easily copy it down. The definintions are not the problem, its the concept. Please Help!!

1. Enzymes
2. DIffusion ( all types)
3. Glycoproteins
4. Mitosis
5. Osmosis
6. Anaphase
7. Glycolipids
8. Metaphase
9. Peptidoglycan
10. Cell
11. haploid
12. Cellulose
13. Thalakoid
14. Nuclear Envelope
15. phagocytosis
16. Gametes
17. Prokaryotic Flagellum
18. Hydrophobic
19. Mattias Schlediden
20. peroxidase
21. Tugor Pressure
22. Chloroplasts
23. Cell Theory
24. Mitochondria
25. Pinocytosis
26. Lignin
27. Hexose
28. Organelless

This is only half of it, like I explained, the definition is not the issue, it is the concept. If I do not understand the concepts, and I don't, There is not hope! ty!!

Is there anyone out there who has actually taken College Level Biology? Because they would understand what i mean by concept! The textbook IS NOT always the answer!!

Answer 1

A "definition", for me, is a "concept" expressed in concise and very clear words.
It follows that if you understand the definitions, you understand the concepts.
Try to use examples of each.
Example of an example, using # 1 and #12 of your list:
Enzyme:
def.: "It is a biological catalyst that speeds up reactions in a cell."
Ex.: Cellulose, a long molecule contained in the fibers of plants, can be digested to small fragments only by organisms that have the enzyme cellulase; cows, a ruminant, have this enzyme in their gastro-intestinal tract, can eat and digest grass (and they like it); human beings don´t - if they eat grass (and they don´t like it) it will be liberated in their feces.
Got it?

Answer 2

These are basic terms used in college level biology, so I really don't see why you can't understand them based on what's in the textbook, because I did.

My suggestion is that to help you grasp the concepts, read through the definitions and then look through worked examples, or read through textbooks that link concepts up together.

You'd find that a lot of the terms you mentioned are related, e.g. mitosis, anaphase, metaphase. Any decent textbook will be able to trace the whole process of mitotic division for you, including what exactly is happening during anaphase and metaphase. The 4 breakdowns are prophase, metaphase, anaphase and finally telophase, and they occur either during mitosis or meiosis.

Answer 3

I think the concept, as described by your instructor, means you know what the term means beyond the simple definition. For instance, you could define cellulose, as "Cellulose (C6H10O5)n is a long-chain polymeric polysaccharide carbohydrate, of beta-glucose [1][2]. It forms the primary structural component of green plants." (as described by wikipedia), but to know the concept, you would also include that cellulose is what gives rigidity to plant cells, which is why plants don't need a skeleton. It is difficult to digest, and also the primary component of paper.
You have too many terms to go through each one in a forum like this...

Answer 4

Okay here we go, I am currently in that class in my college as well.
enzyme- what is made when proteins are combined, and are used as catalyst in the cell. Making sure stuff gets in and out of the cell, and even braking down food to be digested. ex: make up of saliva.

diffusion-is different than osmosis, do not think they are the same thing. Diffusion is any substance off high concentrated to low concentration, making it equal in concentration. Perfume moving thru out the room.

Osmosis is the movement of water across a semi-holey membrane, or semi-permeable membrane ex: cell

Glycoprotein is any covalently bonded to a carb. covalent bonding is referring to the sharing of electrons of certain elements like carbon that is found in glucose that is found in carbs.

There is alot of stuff if you want to email me back and forth to get what you really do no understand you can. [e-mail]

Answer 5

I know the answers to all them. No way am I typing up on all that.
Sorry look up your textbook instead

Answer 6

HAHAHAHA! I just had biology last year, and I have no idea about most of em. He's what my mom would say: " IF YOU DON"T UNDERSTAND THE CHAPTER, READ IT AGAIN!!"

Answer 7

DAGGUM!!! I remember doin' this in 9th grade

Use textbook

Answer 8

all of them are things that deal with single cell organisms.

Answer 9

try www.dictionary.com

they should have all the information in your text book though.

Answer 10

that's a lot...
read your textbook... and if you aren't getting it, read it again and slower.
that's what i do..
