Cells

Question 1

The Outer boundary if the cell, that separates if rom neighboring cells and the external environment. Made of a double layer made of lipid molecules and proteins.

Answer 1

Cell membrane

Question 2

Thick liquid within the cell membrane which has got all the cell structures suspended in it. Cytosol is he liquid part which is 75-90% water.

Answer 2

Cytoplasm

Question 3

Specialized structures suspended in the cytoplasm

Answer 3

Organelles

Question 4

Consists of microfilaments and microtubules that give the cell its shape as well as assisting in movement.

Answer 4

Cytoskeleton

Question 5

A membrane-bound sac that transports materials in and out of the cell.

Answer 5

Vesicles

Question 6

Flattened, membranous bags stacked on top of each other. These modify proteins and package them in vesicles for secretion from the cell (Transport).

Answer 6

Golgi body/apparatus

Question 7

Double membrane- the outer smooth and the inner folded in towards the center of the mitochondrion. Organelle releases energy for the cell through the process of respiration.

Answer 7

Mitochondria

Question 8

Contain enzymes that are able to break down proteins, lipids, nucleic acids, and some carbohydrates. This organelle breaks down materials that are taken into the cell or break down worn out organelles

Answer 8

Lysosomes

Question 9

Made of RNA and proteins. Amino acids are joined together to make the proteins.

Answer 9

Ribosomes

Question 10

Provides a surface on which chemical reactions can occur. Channels between the paired membranes are used for storage or transport of materials. Most have ribosomes (Rough) some have none (Smooth)

Answer 10

Endoplasmic Reticulum

Question 11

Composed mainly of RNA

Answer 11

Nucleolus

Question 12

Contains the generic components, mostly DNA, have nuclear pores, which allows large molecules to pass through.

Answer 12

Nucleus

Question 13

Pair of cyclindrical structures located near the nucleus, involved in

Answer 13

Centrioles

Question 14

Why are cells are so small?

Answer 14

Small cells have a large surface area to volume ratio. This allows all substances needed to pass across to all cell parts.

Question 15

Cell drinking/ Engulf liquid particles

Answer 15

Pinocytosis

Question 16

Cell eating/ Engulf solid particles

Answer 16

Phagocytosis

Question 17

Organelles directly associated with the transport of the synthesized lipase within or from the cells.

Answer 17

Rough Endoplasmic Reticulum
Golgi Body
Vesicles
Plasma membrane
Mitochondria

Question 18

Red Blood Cells, do not have a nucleus.
What processes cant they carry out? And why?

Answer 18

They cant undergo cell division, repair. DNA in the nucleus control these function, DNA replication for cell division

Question 19

What tends to move into the cell by passive transport?

Answer 19

Sodium
Glucose
Oxygen

Question 20

How do amino acids move from the intercellular fluid into the cell? Because they are so large they don’t fit

Answer 20

They move through protein channels

Question 21

Difference between the concentration of oxygen and carbon dioxide inside and outside the cell

Answer 21

Respiration in the cell uses oxygen and produces carbon dioxide.
Keeping oxygen levels low and carbo dioxide levels high inside.
Blood flow to cells supplies oxygen and removes carbon dioxide.
maintaining high oxygen and low carbon dioxide outside of the cell.
