Question 1

Cell theory

Answer 1

• this theory states the observations that explain the relationship between cells and living things, and the origin of cells:

• all living things are made of cells
• cells are the smallest functional unit of life
• cells come from other cells

Question 2

Prokaryotes

Answer 2

•this cell type has a membrane, DNA, Cytoplasm, and ribosomes, but it is very small, lacks a nucleus, and does not have membrane-bound organelles.
-example; bacteria

Question 3

Bacteria

Answer 3

These are common examples of prokaryotes cells

Question 4

Eukaryotes

Answer 4

This cell has a membrane, DNA, cytoplasm, ribosomes, a nucleus, other organelles, and are generally large and complex

Examples- plants, animals, fungi

Question 5

Cell membrane

Answer 5

This is a very thin double-sheet, of special lipids, which covers the exterior of all cells. And allow water to flow freely but others substances do not flow through it freely

Question 6

Cytoskeleton

Answer 6

This is a network of microtubules in the cytoplasm that has a cell maintain its shape

Question 7

Phospholipid

Answer 7

This is a type of lipid that cell membranes are made of the hydrophobic tails point in word away from water and the hydrophilic heads. Outward towards water

Question 8

Selective permeability

Answer 8

This trait means that somethings can pass through easily but others are block from passing through

Question 9

Organelle

Answer 9

This is a small structure in a cell that serves a specific purpose it is a little like an organ in the human body

Question 10

Cell wall

Answer 10

This is a stiff covering that protects plant cells just outside of the cell membrane it is made of cellulose

Question 11

Cytoplasm

Answer 11

This comes from the Greek word for it so it and gel or fluid it is the liquid that sells organelles float in

Question 12

Nucleus

Answer 12

This is the defining organelle of all eukaryotes it contains the DNA of the cell and is enclosed by a special membrane

Question 13

Ribosomes

Answer 13

These are a special kind of enzyme organelle in the cytoplasm of cells they create proteins from amino acid’s by using dehydration synthesis

Question 14

Central vacuole

Answer 14

This is an organelle that is a very large in plants a it stores the water for the plants cell

Question 15

Centrioles

Answer 15

These are a pair of straw shaped structures and animal cells they are the source of microtubules and make up the cytoskeleton

Question 16

Cilia and flagella

Answer 16

These are hairlike structures that help a sound move Celia our lake for or hairs off like flagella or like single long whips

Question 17

Diffusion

Answer 17

This is a form of cellular transport and it solutes slowly move from an area of high concentration to an area of low concentration

Example dissolve sugar or die spreading out in a solution of water

Question 18

Transport protein

Answer 18

This is a protein in the cell membrane that helps molecules move from one side to the other

Question 19

Facilitated diffusion

Answer 19

This is any type of cell transport when the solute is moved from one side of the membrane to the other

Question 20

Channel protein

Answer 20

This is a type of transport protein that only send solutes from high concentration to low concentration just like a Rigid tunnel

Question 21

Active transport

Answer 21

This is the specific type of cell transport in which solutes are pushed against the concentration gradient in other words they are sent from low concentration to high concentration

Question 22

Carrier protein

Answer 22

This is a type of transport proteins that can perform active transport in order for this to happen the transport protein must both change shape and use energy from a TP

Question 23

Osmosis

Answer 23

This is when water moves across a semi permeable membrane from where it is more watery toward where it is less watery

Question 24

Hypertonic solution

Answer 24

This is the solution on the side of the membrane that is more concentrated with solute

Question 25

Hypotonic solution

Answer 25

This is the solution on the side of the membrane that is less concentrated with solute

Question 26

Isotonic solution

Answer 26

This is one of the solutions on both sides of the membrane have the same concentration

Question 27

Exocytosis

Answer 27

This is a complex process in which the cell membrane cents large particles like proteins out of the cell

Question 28

Endocytosis

Answer 28

This is the process in which the cell membrane sends large particles into the cell
