Lesson 3.2 | Cells & Tissue

Question 1

What are the three main components of a composite cell?

Answer 1

Cell Membrane
Cytoplasm
Nucleus

Question 2

What is the Cell Membrane?

Answer 2

It serves as the cell’s boundary, while also having semi-permeable abilities.

Question 3

What is the Nucleus?

Answer 3

The central components of the cell, contains the genetic material DNA (deoxyribonucleic acid)

Question 4

Define Cytoplasm?

Answer 4

Cytoplasm can be defined as the gel-like medium that makes up the cell.

Question 5

Define Organelles?

Answer 5

Essentially the organ system inside a cell, all working together similar to a human body.

Question 6

Define Smooth Endoplasmic reticulum?

Answer 6

Responsible for lipid and cholesterol synthesis

Question 7

Define Rough Endoplasmic reticulum?

Answer 7

Contains ribosomes respobile for protein synthesis

Question 8

Define Ribosomes?

Answer 8

Spherical structures composed of protein and
ribonucleic acid (RNA), responsible for protein synthesis

Question 9

Define Vesicles?

Answer 9

Membranous sacs, responible for transferring material in and out of the cell

Question 10

Define Golgi Apparatus?

Answer 10

Flattened membranous sacs that transport proteins

Question 11

Define Mitochondria?

Answer 11

The powerhouse of the cell, produces ATP from glucose and oxygen

Question 12

Define Lysosomes?

Answer 12

Contains enzymes that destroy cellular Waste

Question 13

What are the two types of movement within a cell?

Answer 13

Diffusion and Osmosis

Question 14

Define Diffusion?

Answer 14

When atoms, molecules, or ions move from areas of greater to lower concentration

Question 15

Define Osmosis?

Answer 15

Movement of molecules through a semi-permeable membrane

Question 16

Define Aerobic Reaction?

Answer 16

Uses oxygen efficiently through cellular respiration to create ATP

Question 17

Anaerobic Reaction?

Answer 17

When a lack of oxygen results in a build-up of Co2 and Lactic acid, causing reduced ATP

Question 18

What are the four main tissue types?

Answer 18

Epithelial (skin)
Connective
Muscle
Nervous tissue

Question 19

Epithelial Tissue?

Answer 19

Essentially skin, serves many functions such as protection, secretion, and filtration

Question 20

Connective Tissue?

Answer 20

Bone, blood, cartilage, and fats are all connective tissues that serve to bind, support, protect, and produce

Question 21

What are the three types of muscle tissue?

Answer 21

Skeletal, smooth, cardiac

Question 22

Smooth muscle tissue?

Answer 22

Muscle that makes up organs like the digestive system, are involuntarily controlled

Question 23

Cardiac Muscle Tissue?

Answer 23

The main composition of the heart, controls it’s pumping

Question 24

Nervous Tissue?

Answer 24

Located in the brain, spinal cord, and nervous. Responsible for coordination and responding to stimuli

Question 25

Skeletal Muscle?

Answer 25

Moves bone and responsible for voluntary motor-controls

Question 26

What are the Eleven Organ systems?

Answer 26

Integumentary
- Largest Organ (skin), protects the body and offers temperature regulation

Skeletal
- The framework of the body

Muscular
- Essentially provides movement both voluntary and involuntary

Nervous
- Made up of nerves connecting the body to the brain, respond to stimuli

Endocrine
- Most complex system, made up of glands that control hormones

Cardiovascular
- Made up of the heart and it’s major arteries

Lymphatic
-Allows for cellular movement in the body, aiding in immunity

Digestive
-Processes nutrients and gets rid of waste within the body

Respiratory
-Allows for oxygen circulation within the body, while getting rid of co2

Urinary
-Allows for fluid/blood filtration, gets rid of any toxins and waste

Reproductive
-Mainly for reproducing, also creates hormones for males and females
