Cells And Tissues Mod 3

Question 1

What are two types of cells?

Answer 1

Prokaryotic and eukaryotic

Question 2

Explain the function of the plasma membrane

Answer 2

Outside of the cell, has proteins, semi permiable

Question 3

Explain the function of cytoplasm

Answer 3

Surrounds all the organelles,home to amino acids

Question 4

Explain the functions of the nucleus

Answer 4

The control centre, has the genetic code, able to duplicate itself

Question 5

Explain the function of ribosomes

What are the two types?

Answer 5

Can be attached to the endoplasmic reticulum or free floating, carry substances through the cytoplasm
Rough ER: collects, folds and transports proteins
Smooth ER: manufactures proteins, fats and carbohydrates

Question 6

Explain the function of the Golgi apparatus

Answer 6

Group of flattened sacs by the nucleus that collect chemicals and transport them to the smooth ER

Question 7

Explain the function of the mitochondria

Answer 7

Powerhouse of the cell, chemical reactions occur giving it power

Question 8

Explain the function of lysosomes

Answer 8

Little digestives enzymes that protect the cell by eating bacteria and any harmful substances

Question 9

What is microvolli and what is it’s function?

Answer 9

Short extensions of the plasma membrane that increases surface area and produce movements and enhances absorption and are commonly found in the bowels

Question 10

What is cilia and what does it do?

Answer 10

Long extensions found on exposed surfaces that move freely helping to propel mucus commonly found in Fallopian tubes

Question 11

What is flagella, it’s function and where is it ONLY found?

Answer 11

Single long projections with a tail

Found only in some

Question 12

What are the three ways of passives transports?

Answer 12

Diffusion, osmosis and filtration

Question 13

Define diffusion

Answer 13

Substances that scatter them selves evenly in open spaces

Question 14

Define osmosis

Answer 14

Diffusion of water through a semi permeable membrane that move from a low to high concentration

Question 15

Define active transport

Answer 15

Moves from a higher to lower concentration requires ion pumps, phagocytosis and pinocytosis

Question 16

Define ion pumps

Answer 16

They use energy to move substances across the cell membrane

Question 17

Explain phagocytosis and pinocytosis

Answer 17

Phagocytosis: eats particles
Pinocytosis: drinks fluids

Question 18

What are the two steps in processing genetic information?

Answer 18

Transcription and translation

Question 19

Define transcription

Answer 19

Unravels so the RNA can replicate a gene from the DNA

Question 20

Define translation

Answer 20

They read the information in the RNA to direct the sequencing of amino acids

Question 21

What are the four types of tissues?

Answer 21

Epithelial, connective, muscle and nervous

Question 22

Define epithelial tissue

Answer 22

Covers and protects your body (skin) it’s functions are secretions and absorption

Question 23

What are the seven types of connective tissues?

Answer 23

Areolar, Adipose, dense, reticular, bone, cartilage and blood
