SCIENCE

Question 1

A process used by microorganisms to preserve food by converting sugars into acids.

Answer 1

Fermentation

Question 2

Controls cell activities and houses DNA, but doesn’t synthesize proteins

Answer 2

Nucleus Function

Question 3

Movement of molecules from high to low concentration without using energy.

Answer 3

Diffusion

Question 4

Known as the powerhouse of the cell; produces energy (ATP).

Answer 4

Mitochondria

Question 5

Microorganisms like Lactobacillus ferment sugars, producing acids (e.g., in yogurt and pickles) to prevent spoilage.

Answer 5

Microorganisms in Food Preservation

Question 6

Organelle that modifies, packages, and transports proteins.

Answer 6

Golgi Apparatus

Question 7

Found in plant cells; the site of photosynthesis.

Answer 7

Chloroplasts

Question 8

enable photosynthesis, converting sunlight into energy for plants.
This is vital for agriculture to produce food crops.

Answer 8

Chloroplasts and Agriculture

Question 9

Plant tissue responsible for transporting water and minerals.

Answer 9

Xylem

Question 10

A specific type of diffusion involving water movement

Answer 10

Osmosis

Question 11

Plants absorb carbon dioxide and release oxygen

Answer 11

Photosynthesis Gas Exchange

Question 12

Organelle is responsible for breaking down waste materials, especially in animal cells.

Answer 12

Lysosomes

Question 13

Microorganisms ferment sugars to produce acids, which help preserve food.

Answer 13

Food Preservation by Microorganisms

Question 14

is crucial for maintaining cell hydration and nutrient absorption, such as water uptake in plant roots

Answer 14

Osmosis

Question 15

Involves Sexual Reproduction in plants

Answer 15

Reproduction with Seeds

Question 16

involves genetic mixing and seeds, creating diversity.

Answer 16

Sexual Reproduction

Question 17

Lysosomes are typically found in animal cells, not plant cells.

Answer 17

Plant Cell Components

Question 18

Found only in plant cells not, in animal cells

Answer 18

Cell Wall Presence

Question 19

Regulates gaseous exchange and water loss in plants.

Answer 19

Stomata Function

Question 20

Major difference: Plant cells have chloroplasts and a cell wall, which animal cells lack.

Answer 20

Plant cells vs. Animal cells

Question 21

(e.g., cuttings) produces identical offspring rapidly.

Answer 21

Asexual Reproduction

Question 22

Requires energy to move molecules against a concentration gradient

Answer 22

Active Transport

Question 23

Sexual reproduction promotes genetic variation, unlike asexual reproduction

Answer 23

Genetic Variation in Reproduction

Question 24

Includes releasing oxygen as a byproduct of photosynthesis

Answer 24

Plant Excretion

Question 25

allow CO2 entry and oxygen release, critical for photosynthesis and plant respiration.

Answer 25

Stomata Function

Question 26

The movement of water through a semipermeable membrane.

Answer 26

Osmosis
