Q

The plasma membrane is a fluid mosaic:

A

Fluid because molecules can move freely past one another

A mosaic because of the diversity of proteins in the membrane

Q

What are ribosomes and what do they do?

A

Ribosome components are made in the nucleolus but assembled in the cytoplasm and are responsible for protein synthesis.

Q

What do the lipids belong to?

A

special category called phospholipids which form a two-layered membrane, the phospholipid bilayer.

17
Q

The nucleus is bordered by a double membrane called…

A

the nuclear envelope.

18
Q

Ribosomes (the small blue dots)

A

Synthesise protein by mixing the mRNA and protein

19
Q

mRNA

A

Carries the genetic message form the DNA to the ribosomes

20
Q

ER

A

Makes molecules.

21
Q

Rough ER

A

Studded with ribosomes and transports protein by pinching off into a vesicle

22
Q

Chlorophyll

A

A light absorbing molecule in chloroplasts that converts solar energy into chemical energy

22
Q

Photosynthesis equation

A

Carbon dioxide+water+light energy+glucose+oxygen gas

6co2 6H2O C6H12o6 6o2

22
Autotrophs
Self feeders
22
Cellular respiration
The main way chemical energy is harvested from food and converted into ATP
22
Where does cellular respiration take place?
The Mitochondria
22
What are the three stages of cellular respiration?
Glycolysis The citric acid cycle Electron transport
22
Mitosis
Growth Repair Asexual reproduction
22
Meiosis
Sexual reproduction
22
What happens during cell devision?
Each daughter cell gets a set of chromosomes
22
What is cell decision?
It replaces damaged cells by dividing into and making a copy of itself
22
The cell cycle consists of two distinct phases:
Interphase | Mitonic phase
22
During Interphase a cell:
Double everything
23
During mitosis the mitosis spindle;
Guides the separation of two sets of daughter chromosomes
24
What happens during glycolysis?
Glucose is broken in half and donate high energy and can make two ATP per glucose.
25
Which stage of cellular respiration produces the most ATP?
Electron transport
26
What does anaerobic mean?
Without oxygen
27
What is a waste product of photosynthesis?
Glucose and O2
28
Which stages of cellular respiration take place in the mitochondria?
The citric acid cycle | The electron transport
29
Glycolysis produces ATP even without----
O2
30
Mitosis cycle
``` Interphase Prophase Metaphase Anaphase Telophase and cytokinesis ```
