Q

Structure vs function

A

all organisms need to certian things to survive like move but different organism move differently some animals have wings some have feet some have tails just like moving theres different ways to breath like gills, lungs, spiracle,skin.

Q

Vacuole

A

Organelles that store water and other substances we required by the cell

20
Q

Golgi apparatus

A

A major organelle it’s acts to process and package the macromolecules such as proteins and liquids that are synthesized by the cell

21
Q

Lysosomes

A

An organelle in the silo plasm containing degradative enzymes enclosed Ina membrane

22
Q

Nuceolos

A

A small dense spherical structure in the nucleus of cell during interphase

23
Q

Endiplasmic reticlum

A

A small sense spherical structure in the nucleus of a cell during interphase

24
Q

Plasma membrane

A

The plasma membrane is the boundary between the celll and its environment. It regulate what enters and exits the cell

25
Q

Ribosomes

A

A minute particle consisting RNA and associated proteins, found in large numbers in he cytoplasm of living cells. They bind messages RNA and transfer RNA to synthesize polypeptides and proteins

26
Q

Multicellular

A

Made up of two or more cells

27
Q

Unicellular

A

Made of one cell

28
Q

Cells

A

Cells are the smallest known functioning units of light all organisms must be made of at least one cell

29
Q

What’s the smallest group of organism so far

A

Mycoplasma

30
Q

Unicellular

A

One cell unicellular organisms do most things we need cells to do like it move react to stimuli get rid of raced and reproductive

The key is Uni cellular organisms develop specialized structures to perform these functions they rely on a single celled to meet all their needs

31
Q

Multicellular

A 
Multicellular organisms things we cells to do to be a living thing
Eat
Move
React to stimuli 
Get ride of waste 
Reproduct

The Key is multicellular organisms have many specialized cells that interact to perform these functions they rely on others to meet all of their needs

32
Q

Amoeba

A 
Amoebas  
Common
 living in water
uniclellular
Move with foot like projections 
Pseudopods is what they catch food witj
33
Q

Pseudopods

A

Engulfs the food and creates a vacuole where the food is digested and absorbed into the cytoplasm

34
Q

Paramecium

A

Unicellular
Live in water
Move around swiftly in water with hair life cilia

Catch food with cilia

35
Q

Cilia

A

Oral groove uses cilia to sweep In food create food vacuole that is digusted and then aborted into the cytokines

36
Q

Specialized cells

A

Most multicellular organisms are made up of specialized cells for

37
Q

Are tissues are most organs made up of

A

Connective tissue nervous tissue muscle tissue and epithelial tissue

38
Q

Connective tissue

A

Support and connects different parts of the body example bones fat cartilage and tendons in blood

39
Q

Nervous tissue

A

Mix up the brain spinal cord and nerves

40
Q

Epithelial tissue

A

Covers the surface of your body in the outside of your organs also lines the inside of some organs like the small instestine

Skin

41
Q

Muscle tissue

A

Allows the body muscle to move cart lick muscle to pump blood and in test dine muscle to move food

42
Q

Plant tissues

A 
A plant has three main tissues 
1. Phtosynthetic/storage
2. Protective 
3.transport
Xylem water and phloem food
43
Q

The tissues in a leaf

A 
1. Phtosynthetic/storage
Uses sunlight to produce sugar as food
2. Protective 
Waterproof and protects plant
3.transport
Tubelike cells with hollow centre
44
Q

In a stem

A 
1. Phtosynthetic/storage
Support plant stores food
2. Protective 
Waterproof and protects plant
3.transport
45
Q

In roots

A 
1. Phtosynthetic/storage
Stores food
2. Protective 
Absorbs water from the soil
3.transport
Xylem and phloem are surrounds by circle of cells
46
Q

Diffusion

A

Diffusion is the movement of particles from an area where there are more of them to an area where there are fewer of them

Or

They fusion moves particles from a more concentrated area to a less concentrated area to even them out

47
Q

Osmosis

A

Osmosis is die fusion with water
