24
Q

The cell cycle

What is vital to normal growth and development of a cell?

A

Controlling the rate and timing is vital to normal growth and development

25
Parts of the cell What does the rough endoplasmic reticulum do?
Associates with making proteins
26
The cell cycle How many skin cells do we loose approximately each year?
Approximately 3kg
27
Parts of the cell Is cytoplasm found in all cells?
Yes
28
Cell theory What is biology?
Biology is a natural science concerned with the study of life and living organisms including the structure, function, growth, evolution, distribution and taxonomy
29
Parts of the cell What is the cytoskeleton made up of?
Protein filaments it helps maintain cell shape
30
The cell cycle What are the skin cels replaces by?
Cell division
31
Parts of the cell What does the nucleus do?
Controls all the activity in a cel including growth and reproduction
32
Parts of the cell What are the possible functions of organelles
``` Intake of nutrients Exchange of gasses Movement Waste removal Growth reproduction Response to stimuli ```
33
Parts of the cell What happens in the lysosomes
This is where digestion takes place
34
The cell cycle When do the DNA checkpoints occur?
G1 G2 Mphase
35
Parts of the cell What does the smooth endoplasmic reticulum do?
Production of fats and oils
36
The cell cycle What are the three reasons the cell will stop at a checkpoint?
There are not enough nutrients to support cell growth The DNA has not replicated properly The DNA is damaged
37
Parts of the cell What are ribosomes?
Small dense looking organelles that may be attached to the rough endoplasmic reticulum or free in the cytoplasm
38
The cel cycle What happens at each checkpoint?
Special proteins halt the cycle until they receive signals that allow it to proceed
39
Parts of the cell What does chlorophyll use energy from the sun for?
To convert carbon dioxide and water into sugar and oxygen in a process called photosynthesis
40
The cell cycle How many phases are in the cell cycle?
2 phases each with sub phases
41
Parts of the cell What happens in the mitochondrion?
Reactions occur in these organ cells to convert the chemical energy in sugar into energy that the cell can use
42
The cell cycle What do the molecules control?
The control the whole cell cycle
43
Parts of the cell What are thylakoids and where are they found?
Thylakoids collect light energy from the sun, they are found in the chlorophyll
44
Cell cycle What is the function of molecules?
The function of molecules many of them proteins, carry messages between cells
45
Parts of the cell What is the cell wall?
A rigid frame around the cell
46
The cell cycle Does cell division need to be controlled for the cell to function?
Yes or the organism won’t function properly
47
Parts of the cell What are lysosomes filled with?
Enzymes
48
Cel theory What is the development of cell theory?
All plant parts are made of cells
49
Parts of the cell What does the cytoplasm contain?
Nutrients required by the cel to carry in its life process
50
The cell cycle How long does it take for the skin cell to reach the surface once it divides
It takes about 2 weeks to move to the surface
51
Parts of the cell What does the cell wall do?
Provides strength protection and support to the cell
52
The cell cycle How many sub-phases are in the M-phase?
2 mitosis and cytokinesis
53
Parts of the cell Are all cells identical?
No not all cells are identical
54
The cell cycle How many sub phases are in interphase?
3 G1 G2 Sphase
55
Parts of the cell What does the chloroplast contain?
A green substance called chlorophyll
56
The cell cycle What checkpoints is the most important? What happens to many cells after that checkpoint?
For many cells the most important is after mphase. Most s leave the cycle and take on specific roles. Specialization.
