Question 1

Plant and animal cell

Cell wall cell membrane chloroplast mitochondria

Answer 1

Cell wall made of cellulose gives structure we cannot digest it

Cell membrane phospholipid bilayer selectively permeable membrane diffusion and osmosis active transport

Chloroplast photosynthesis CO2+H2O+sun—–>O2+C6H12O6

Mitochondria cellular respiration C6H12O6+O2—>CO2+H2O+energy

Question 2

Cell cycle

Answer 2

Interphase mitosis prophase metaphase anaphase telephase

Question 3

Rates of cell cycle

Answer 3

0-2 fastest
11-17 second fastest
Late twenties early thirties slows down with age

Question 4

Mutations

Answer 4

A biological error often in interphase
A mistake I. The DNA patern
Mutagens dehydration starvation radiation drugs

Question 5

Asexual reproduction

Answer 5

Fragmentation starfish 
Budding yeast 
Spore formation mushrooms
Vegetative reproduction strawberry 
Binary fission bacteria

Question 6

Sexual reproduction terms

Answer 6

Haploid half copy of DNA
Diploid full copy of DNA
Gamete matured Haploids
Zygote the first cell

Question 7

Male and female reproductive terms

Answer 7

Female: ovaries phelopean tube uterus cervix vagina

Male: testicle scrotum epididymis vas deferns Cowper’s glands prostate seminal vesicles urethra penis seminiferous tubes

Ectopic pregnancy when the zygote stays in the phelopean tube and starts to devide

Question 8

Cell theory

Answer 8

All living things are made up of one of more cells

The cell is the unit of life

All cells come from Pre existing cell
