Q

What are red blood cells?

A

they are donut shaped. This shape helps them squeeze through tiny blood vessels and deliver oxygen to the parts of the body

Q

What are immune cells?

A

these cells are like the defenders of the body. They fight off sicknesses and destroy things like bacteria, germs and fungi

Q

What is the plasma membrane and what is it made of?

A

It surrounds the cell and it determines what comes in and out of the cell. It is made up of cholestrol, proteins, and lipids

Q

What is cyptoplasm?

A

it is a gel like substance that fills up the space between the plasma membrane and the nuclues. it fills up the rest of the cell

Q

What is lyosomes?

A

gets rid of waste material the cell does not need. It helps breakdown protein the cell does not need.

Q

What is golgi appratus?

A

they are vesicles that transport protein. It receives proteins from the ER and prepares them to send it to other parts of the body

15
Q

What is Endoplasmic Reticlum?

A

it helps make sure that proteins and fats are produced or made, packaged and sent to the right places in the cell where its needed

16
Q

Why is the cell membrane selectively permable?

A

It’s because some substances pass through the cell while others cant

17
Q

What is passive transport?

A

It requires no energy. It includes diffusion, osmoisis, filiration and facilitated diffusion

18
Q

What is diffusion?

A

it involves movement of particles from an area of high concentration to low concentration

19
Q

What is diffusion driven by?

A

it is driven by concentration gradient. Its like a driving force that influences the movement of substances

20
Q

What is filiteration?

A

causes by differences in pressure. It uses pressure gradients to force liquids and small solutes through a membrane

21
Q

What is osmosis pressure?

A

the pressure that develops from osmosis

22
Q

What is osmoisis?

A

Osmoisis is the movement of water. Its like diffusion except its the water that comes into and out of the cell.

23
Q

What does osmosis help with?

A

Osmosis helps if things or substances or even a solute cant pass through the membrane. The osmosis helps it get into the cell.

24
Q

If the cell needs water who comes in the picture?

A

Osmosis

25
Q

What is active transport?

A

solutes go from low concentration to high concentration

26
Q

What types of active transport is found in the cell?

A

active transport pump, phagotycysis, pincytosis, exocytisis

27
Q

What is isotonic?

A

water moves into and out of the cell at the same rate. It has the same amount of salt in and outside of the cell so it doesnt require movement.

28
Q

what is hypertonic?

A

when the cell loses water- it shrinks- it has more salt. If theres too much salt in the cell, water moves out because it bad for it.

29
Q

What is hypotonic?

A

water flows into the cell- the cell will swell up and it will burst called lysis. It has less salt in the cell

30
Q

What is DNA

A

Itc arries the genetic information of a cell

31
Q

Where is DNA located?

A

the nucleus

32
Q

What is the two processes in protein syntesis?

A

Transcription and translation

33
Q

What are the stages in the cell cylcle?

A

First gap phase, sysnthesis phase, second gap phase, and mitotic phase

34
Q

what is microbiome?

A

*Microbiome is the good bacteria and if you have the bad bacteria, you will get sick

35
Q

How is microbiome developed?

A

The first step into building microbiome occurs before birth

36
Q

What are factors that can improve microbiome?

A

Excercising, spending time outdoors, eating a plat based diet and taking prebiotics

37
Q

What are threats to microbiome?

A

Stress, smoking high fat and high sugar diet

38
