Isaac Newton
Charles Darwin
Gregor Mendel
Louis Pasteur
Question 2
2.
What biological concept did Mendel's experiments with pea plants help uncover?
Metabolism
Heredity
Cell division
Photosynthesis
Question 3
3.
Why are Mendel's hereditary findings relevant to humans?
They explain human anatomy
They apply to all sexually reproducing living things
They are exclusive to humans
They explain human evolution
Question 4
4.
What attribute made Mendel's work particularly significant?
Curiosity, scientific methods, and good luck
His wealthy background
Sophisticated laboratory equipment
Opportune timing
Question 5
5.
What is the science of heredity referred to as?
Geology
Genetics
Chemistry
Biology
Question 6
6.
Why did offspring resemble their parents in Mendel's experiments?
It was a coincidence
They had similar environments
It was due to nurture not nature
Characteristics are inherited
Question 7
7.
In which country was Gregor Mendel born?
Austria
Germany
France
Switzerland
Question 8
8.
Which plant is Gregor Mendel best known for experimenting with?
Corn plant
Rose plant
Sunflower plant
Pea plant
Question 9
9.
What was the blending theory of inheritance popular in Mendel's time?
Offspring inherit the least dominant traits
Offspring characteristics are unrelated to parent's
Characteristics of only one parent are inherited
Offspring are a mix of the parent's characteristics
Question 10
10.
Why did Mendel question the blending theory of inheritance?
He noticed plants that weren't a blend of the parents
He believed the theory was widely accepted
He thought the theory was too complex
Plants in his garden contradicted Darwin’s theory of evolution
Question 11
11.
Approximately how many pea plants did Mendel experiment with?
Approximately 300
About 3 million
Around 3,000
Almost 30,000
Question 12
12.
Why did Mendel choose pea plants for his genetics experiments?
They were easy to find in his location.
Pea plants were his favourite.
They were the only plants available.
Fast-growing, easy to raise, with multiple visible characteristics.
Question 13
13.
What visible characteristics vary in pea plants?
Only stem length.
Seed form/color, flower color, pod form/color, placement, stem length.
Only pod form and color.
Only seed form and color.
Question 14
14.
How many common values does each characteristic have in pea plants?
Four
Two
One
Three
Question 15
15.
What may the flower color of a pea plant be?
Orange or brown
Blue or green
Red or yellow
White or purple (violet)
Question 16
16.
What do cotyledons refer to in gregor Mendel's experiments?
Seed shells
The tiny leaves inside seeds
Roots of the plants
Pods of the plants
Question 17
17.
Where are axial pods located on pea plants?
At the ends of the stems
Inside the seeds
Along the stems
At the top of the plant
Question 18
18.
Where are terminal pods located on pea plants?
Along the stems
Inside the seeds
At the ends of the stems
At the base of the plant
Question 19
19.
What part of the flower produces the male gametes of plants?
Ovary
Anther
Stigma
Petal
Question 20
20.
What is the correct term for the fertilization step in the plant's sexual reproduction?
Conjugation
Germination
Replication
Pollination
Question 21
21.
What is the role of the stigma in a flower?
It passes pollen grains to female gametes in the ovary
It protects the ovary
It produces pollen grains
It transfers pollen to the anther
Question 22
22.
What is the term for the process where pollen is transferred from the anther to the stigma?
Fertilization
Germination
Pollination
Translation
Question 23
23.
What are the reproductive organs of plants?
