Cells

Question 0

Organelle

Answer 0

Specalized structure that performs important cellular functions within a eukaryotic cell
Ex: Golgi bodies, mitochondria, nucleus, etc.

Question 2

Cell membrane

Answer 2

Thin, flexible barrier around a cell, regulates what enters and leaves the cell
It’s found on a plant and animal cell
If the molecule is too large than it can’t go through
Can only go through if it’s small enough

Question 3

Cell wall

Answer 3

Strong supporting layer around the cell membrane in plants, algae, and some bacteria
Found only on plant cells, not animal cells
Made out of cellulose

Question 4

Chloroplast

Answer 4

Organelle found in cells of plants and some other organisms that captures energy from sunlight and converts it into chemical energy
Contains green pigment, chlorophyll
Used to make food during photosynthesis

Question 5

Chlorophyll

Answer 5

Principal pigment of plants and other photosynthetic organisms; captures light energy
It’s green
In the chloroplast

Question 6

Cytoplasm

Answer 6

Material inside the cell membrane-not including the nucleus
Like gel
Makes up most of the cell

Question 7

Mitochondria

Answer 7

Cell organelle that converts the chemical energy stored in food into compounds that are more convenient f the cell to use
Mighto/ lighto
Mighty Mitochondria
Power house of the cell

Question 8

Nucleus

Answer 8

Structure that contains the cell’s genetic material(DNA) and controls the cells activities
“Boss” of the cell

Question 9

Chromatin/Chromosomes/ DNA

Answer 9

(There are differences in these words that we will learn later)- genetic material
Gives the certain code to the messenger RNA to give to the ribosomes to make the proteins

Question 10

Ribosome

Answer 10

Small particle in the cell on which proteins are assembled; made of RNA & protein
Also found on the ER and in the cytoplasm

Question 11

Vacuole

Answer 11

Cell organelle that stores materials such as water, salts, proteins, and carbohydrates
Stores like a vacuum

Question 12

Eukaryotic cell

Answer 12

Cell that contains a nucleus

Plant and animal cell

Question 13

Prokaryotic cell

Answer 13

Unicellular organism without a nucleus

Bacteria cell

Question 14

Cell specialization

Answer 14

The process in which cells develop in different ways to perform different tasks
Chemical signals tell each cell which genes to read
Cells - tissues - organs - organ systems - organisms

Question 16

Antigen

Answer 16

Protein marker on cell membrane

Induces information of antibodies because it is recognized by the immune system as foreign to the body

Question 17

Diffusion

Answer 17

Process by which molecules tend to move from an area of high concentration to an area where they are less concentrated
ATP is not used
It’s a passive transport

Question 18

Osmosis

Answer 18

Diffusion of water through a selectively permeable membrane

Question 19

Cellular respiration

Answer 19

Energy releasing process
Puts carbon dioxide back and takes oxygen
Happens in the mitochondria
Oxygen+ Glucose-> CO2+ Water

Question 20

Photosynthesis

Answer 20

Biochemical food making process
Removes carbon dioxide releases oxygen
Happens in the chloroplasts
Carbon dioxide+ water-> glucose & oxygen
